Virginia Tech won its first game without nearly two dozen players and even some coaches unavailable due to a combination of coronavirus and injury issues. The question is whether they’ll be shorthanded again when they play Saturday at Duke.
The Hokies (1-0, 1-0 Atlantic Coast Conference) beat North Carolina State last weekend despite missing 23 players and two full-time coaches, including starting quarterback Hendon Hooker and defensive coordinator Justin Hamilton. That came days after coach Justin Fuente had wondered aloud whether his team would have enough players to even take on the Wolfpack.
Fuente said preparation must include ensuring both coaches and players are ready to take on multiple roles if needed due to an injury, positive COVID-19 test, quarantine or any other potential issue.
“There’s no guarantee that we’ll have a full complement of everybody coming into the next week,” Fuente said. “So it was nice for us to get to do it. It was nice for us to play well. Certainly I don’t want to make too much of it. There’s plenty of things that we’ve got to do better that other people on our schedule, starting with Duke, will highlight if we don’t get fixed.”
The Blue Devils have their own problems, though. Namely, turnovers.
Duke (0-3, 0-3) have lost 14 turnovers in three games, the most among all 72 Bowl Subdivision teams who have taken the field so far this season. The Blue Devils committed five turnovers in a home loss to Boston College on Sept. 19, then followed with seven turnovers – five coming on interceptions – in last weekend’s loss at Virginia.
The Blue Devils led that game 20-17 entering the fourth quarter, but had a run of four straight turnovers starting late in the third as the Cavaliers pushed ahead.
“There’s not a play on the practice field, not one play, that we’re not coaching ball security better,” Duke coach David Cutcliffe said. Obviously, it’s not been done well enough on my part. … You might not believe this, but we’re close. And so we’re certainly not going to lose hope, we’re not going to run from the challenge. We’re going to run to it.”
Here are things to know about Saturday’s Virginia Tech-Duke game:
HOOKER’S STATUS
Fuente said this week that he expects Hooker to be available, but he didn’t say whether Hooker would start or even play. Hooker missed the opener and Braxton Burmeister started, while Quincy Patterson II also played – and threw for two touchdowns – when Burmeister experienced a hand cramp.
BRICE AND TURNOVERS
Clemson graduate transfer Chase Brice is having trouble protecting the football for the Blue Devils, throwing four interceptions against Virginia while also losing two fumbles this season.
“We’ve got to give him more time so he feels more comfortable in the pocket,” offensive tackle Casey Holman said. “So he can move around, he can go through his progressions and he can make the throws we all know he can.”

GRINDERS
The Hokies ran for 314 yards in their opener, with five players running for at least 40 yards.
Kansas graduate transfer Khalil Herbert led Virginia Tech with 104 yards and a score on six carries. Receiver Tre Turner also had a 51-yard burst on a jet sweep, while Patterson (47 yards) and Burmeister (46) provided production from the QB position.
TURNING POINT
Duke won last year’s meeting 45-10 on the road. That performance included 21 second-quarter points, two second-half touchdown runs of at least 30 yards, a successful fake punt with a 38-10 fourth-quarter lead and a defensive effort that held the Hokies to 259 yards.
Virginia Tech responded by winning six of seven before reaching a bowl game.
“We were a different team for the better after that,” Fuente said, adding: “We have an opportunity now to see if we have improved.”
A FIRST Millumin 3 v3 14 d.
Duke is 0-3 for the first time in 13 seasons under Cutcliffe and 0-3 in ACC play for the first time since 2016. The Blue Devils hadn’t started 0-3 overall since an 0-12 season in 2006 under Ted Roof.

-->The primary difference and reasons for updating the Windows Subsystem for Linux from WSL 1 to WSL 2 are to:
- increase file system performance,
- support full system call compatibility.
WSL 2 uses the latest and greatest in virtualization technology to run a Linux kernel inside of a lightweight utility virtual machine (VM). However, WSL 2 is not a traditional VM experience.
Comparing features
Feature | WSL 1 | WSL 2 |
---|---|---|
Integration between Windows and Linux | ✅ | ✅ |
Fast boot times | ✅ | ✅ |
Small resource foot print | ✅ | ✅ |
Runs with current versions of VMware and VirtualBox | ✅ | ✅ |
Managed VM | ❌ | ✅ |
Full Linux Kernel | ❌ | ✅ |
Full system call compatibility | ❌ | ✅ |
Performance across OS file systems | ✅ | ❌ |
As you can tell from the comparison table above, the WSL 2 architecture outperforms WSL 1 in several ways, with the exception of performance across OS file systems.
Performance across OS file systems
We recommend against working across operating systems with your files, unless you have a specific reason for doing so. For the fastest performance speed, store your files in the WSL file system if you are working in a Linux command line (Ubuntu, OpenSUSE, etc). If you're working in a Windows command line (PowerShell, Command Prompt), store your files in the Windows file system.
For example, when storing your WSL project files:
- Use the Linux file system root directory:
wsl$Ubuntu-18.04home<user name>Project
- Not the Windows file system root directory:
C:Users<user name>Project
All currently running distributions (
wsl -l
) are accessible via network connection. To get there run a command [WIN+R] (keyboard shortcut) or type in File Explorer address bar wsl$
to find respective distribution names and access their root file systems.You can also use windows commands inside WSL's Linux Terminal. Try opening a Linux distribution (ie Ubuntu), be sure that you are in the Linux home directory by entering this command:
cd ~
. Then open your Linux file system in File Explorer by entering (don't forget the period at the end): powershell.exe /c start .
Important
If you experience an error -bash: powershell.exe: command not found please refer to the WSL troubleshooting page to resolve it.
WSL 2 is only available in Windows 10, Version 1903, Build 18362 or higher. Check your Windows version by selecting the Windows logo key + R, type winver, select OK. (Or enter the
ver
command in Windows Command Prompt). You may need to update to the latest Windows version. For builds lower than 18362, WSL is not supported at all.Note
WSL 2 will work with VMware 15.5.5+ and VirtualBox 6+. Learn more in our WSL 2 FAQs.
What's new in WSL 2
WSL 2 is a major overhaul of the underlying architecture and uses virtualization technology and a Linux kernel to enable new features. The primary goals of this update are to increase file system performance and add full system call compatibility.
WSL 2 architecture
A traditional VM experience can be slow to boot up, is isolated, consumes a lot of resources, and requires your time to manage it. WSL 2 does not have these attributes.
WSL 2 provides the benefits of WSL 1, including seamless integration between Windows and Linux, fast boot times, a small resource footprint, and requires no VM configuration or management. While WSL 2 does use a VM, it is managed and run behind the scenes, leaving you with the same user experience as WSL 1.

Full Linux kernel
The Linux kernel in WSL 2 is built by Microsoft from the latest stable branch, based on the source available at kernel.org. This kernel has been specially tuned for WSL 2, optimizing for size and performance to provide an amazing Linux experience on Windows. The kernel will be serviced by Windows updates, which means you will get the latest security fixes and kernel improvements without needing to manage it yourself.
The WSL 2 Linux kernel is open source. If you'd like to learn more, check out the blog post Shipping a Linux Kernel with Windows written by the team that built it.
Increased file IO performance
File intensive operations like git clone, npm install, apt update, apt upgrade, and more are all noticeably faster with WSL 2.
The actual speed increase will depend on which app you're running and how it is interacting with the file system. Initial versions of WSL 2 run up to 20x faster compared to WSL 1 when unpacking a zipped tarball, and around 2-5x faster when using git clone, npm install and cmake on various projects.
Full system call compatibility
Linux binaries use system calls to perform functions such as accessing files, requesting memory, creating processes, and more. Whereas WSL 1 used a translation layer that was built by the WSL team, WSL 2 includes its own Linux kernel with full system call compatibility. Benefits include:
- A whole new set of apps that you can run inside of WSL, such as Docker and more.
- Any updates to the Linux kernel are immediately ready for use. (You don't have to wait for the WSL team to implement updates and add the changes).
WSL 2 uses a smaller amount of memory on startup
WSL 2 uses a lightweight utility VM on a real Linux kernel with a small memory footprint. The utility will allocate Virtual Address backed memory on startup. It is configured to start with a smaller proportion of your total memory that what was required for WSL 1.
Exceptions for using WSL 1 rather than WSL 2

Money pro 2 0 700. We recommend that you use WSL 2 as it offers faster performance and 100% system call compatibility. However, there are a few specific scenarios where you might prefer using WSL 1. Consider using WSL 1 if:
- Your project files must be stored in the Windows file system. WSL 1 offers faster access to files mounted from Windows.
- If you will be using your WSL Linux distribution to access project files on the Windows file system, and these files cannot be stored on the Linux file system, you will achieve faster performance across the OS files systems by using WSL 1.
- A project which requires cross-compilation using both Windows and Linux tools on the same files.
- File performance across the Windows and Linux operating systems is faster in WSL 1 than WSL 2, so if you are using Windows applications to access Linux files, you will currently achieve faster performance with WSL 1.
Note
Consider trying the VS Code Remote WSL Extension to enable you to store your project files on the Linux file system, using Linux command line tools, but also using VS Code on Windows to author, edit, debug, or run your project in an internet browser without any of the performance slow-downs associated with working across the Linux and Windows file systems.

Accessing network applications
Nice Todo 2 0 5d 3
Accessing Linux networking apps from Windows (localhost)
If you are building a networking app (for example an app running on a NodeJS or SQL server) in your Linux distribution, you can access it from a Windows app (like your Edge or Chrome internet browser) using
localhost
(just like you normally would).However, if you are running an older version of Windows (Build 18945 or less), you will need to get the IP address of the Linux host VM (or update to the latest Windows version).
To find the IP address of the virtual machine powering your Linux distribution:
- From your WSL distribution (ie Ubuntu), run the command:
ip addr
- Find and copy the address under the
inet
value of theeth0
interface. - If you have the grep tool installed, find this more easily by filtering the output with the command:
ip addr | grep eth0
- Connect to your Linux server using this IP address.
The picture below shows an example of this by connecting to a Node.js server using the Edge browser.
Accessing Windows networking apps from Linux (host IP)
If you want to access a networking app running on Windows (for example an app running on a NodeJS or SQL server) from your Linux distribution (ie Ubuntu), then you need to use the IP address of your host machine. While this is not a common scenario, you can follow these steps to make it work.- Obtain the IP address of your host machine by running this command from your Linux distribution:
cat /etc/resolv.conf
- Copy the IP address following the term: nameserver
.- Connect to any Windows server using the copied IP address.The picture below shows an example of this by connecting to a Node.js server running in Windows via curl.
Additional networking considerations
Connecting via remote IP addresses
When using remote IP addresses to connect to your applications, they will be treated as connections from the Local Area Network (LAN). This means that you will need to make sure your application can accept LAN connections.
For example, you may need to bind your application to
0.0.0.0
instead of 127.0.0.1
. In the example of a Python app using Flask, this can be done with the command: app.run(host='0.0.0.0')
. Please keep security in mind when making these changes as this will allow connections from your LAN.Accessing a WSL 2 distribution from your local area network (LAN)
When using a WSL 1 distribution, if your computer was set up to be accessed by your LAN, then applications run in WSL could be accessed on your LAN as well.
This isn't the default case in WSL 2. WSL 2 has a virtualized ethernet adapter with its own unique IP address. Currently, to enable this workflow you will need to go through the same steps as you would for a regular virtual machine. (We are looking into ways to improve this experience.)
Here's an example PowerShell command to add a port proxy that listens on port 4000 on the host and connects it to port 4000 to the WSL 2 VM with IP address 192.168.101.100.
IPv6 access
WSL 2 distributions currently cannot reach IPv6-only addresses. We are working on adding this feature.
Expanding the size of your WSL 2 Virtual Hard Disk
WSL 2 uses a Virtual Hard Disk (VHD) to store your Linux files. In WSL 2, a VHD is represented on your Windows hard drive as a .vhdx file.
The WSL 2 VHD uses the ext4 file system. This VHD automatically resizes to meet your storage needs and has an initial maximum size of 256GB. If the storage space required by your Linux files exceeds this size you may need to expand it. If your distribution grows in size to be greater than 256GB, you will see errors stating that you've run out of disk space. You can fix this error by expanding the VHD size.
Nice Todo 2 0 5d Mark Ii
To expand your maximum VHD size beyond 256GB:
- Terminate all WSL instances using the command:
wsl --shutdown
- Find your distribution installation package name ('PackageFamilyName')
- Using PowerShell (where 'distro' is your distribution name) enter the command:
Get-AppxPackage -Name '*<distro>*' | Select PackageFamilyName
- Locate the VHD file
fullpath
used by your WSL 2 installation, this will be yourpathToVHD
:%LOCALAPPDATA%Packages<PackageFamilyName>LocalState<disk>.vhdx
- Resize your WSL 2 VHD by completing the following commands:
- Open Windows Command Prompt with admin privileges and enter:
- Examine the output of the detail command. The output will include a value for Virtual size. This is the current maximum. Convert this value to megabytes. The new value after resizing must be greater than this value. For example, if the detail output shows Virtual size: 256 GB, then you must specify a value greater than 256000. Once you have your new size in megabytes, enter the following command in diskpart:
- Exit diskpart
- Launch your WSL distribution (Ubuntu, for example).
- Make WSL aware that it can expand its file system's size by running these commands from your Linux distribution command line.NoteYou may see this message in response to the first mount command: /dev: none already mounted on /dev. This message can safely be ignored.Copy the name of this entry, which will look like:
/dev/sdX
(with the X representing any other character). In the following example the value of X is b:NoteYou may need to install resize2fs. If so, you can use this command to install it:sudo apt install resize2fs
.The output will look similar to the following:
Note
In general do not modify, move, or access the WSL related files located inside of your AppData folder using Windows tools or editors. Doing so could cause your Linux distribution to become corrupted.
