Hello

I have windows 10 with last updates and installed few VM like "Windows 10 dev" and "ubuntu 20.04". My question is how to access to usb device from Ubuntu VM? 

When I run "windows 10 dev" VM it allow me use enhanced session mode and there I can share those usb devices, but for ubuntu and other VM based on linux I dont see that option. So how to do if "enhanced session" mode doesnt work for those
VM?

Whenever I try to move the VM the following error message appears: Live migration of ‘Virtual Machine GameCache’ failed. But with all other VMs the migration works. Does anyone know what the error could be?

Hi 

I have copied from backup the disk images of a server 2016 which was running on a HyperV (2016) server and re created the server on a new server ( same spec, make and model), I have used server 2016 again and created with the same named virtual switch 

when i boot up the VM the server loads ok and lets me log in BUT the network card has no IP4 or IP6 protocols.If i try add them it says that the feature cannot be added as the file cannot be created as the file already exists.

I have tried deleting the network card and rebooting

I have tried showing disabled adaptors in device manager and removed them 

any ideas what to do next.

I restored another server (2012r2 the same way on the same new server and this works perfectly so I dont think its the Virtual switch thats at fault, 

any advice would be great

Thanks

Hi Hope someone can assist 

I have copied a VM servers data drives  from  a backup of a DELL hyperv server to a different Hyperv server of the same spec, 

I have re created the server and attached the drives, when I boot up the server ( server 2016) it loads ok and lets me log in BUT

the Virtual nic adapter has a red cross, when I go look at it, it is missing ip4 and ip6 protocols, if I try add them I get the error "could not add the requested feature, the error is: cannot create file when file already exists"

I have removed all old network devices from device manager and also tried recreating the network on the HyperV Host 

I have a second also copied server running on this backup server ( server2012r2) attached to the same virtual network and this is ok. 

any ideas what would cause this

thanks in advance

I create a new virtual disk and choose to copy the contents of the physical disk and get an error.

Hello Fellow Hyper-V Engineers,

I am trying to find a solution in my org at my company to find a method of tracking meta-data that could be used as a UUID for an automation system where VMs would be decommed and deleted via a customer facing portal.   My problem here is that
Hyper-V does not have legit UUIDs for VMs as they can be changed when migrated across clusters, be empty (due to error ) or be copied from a clone.

I am trying to find an easy and practical solution like perhaps parsing the licensing meta-data of a VM when trying to identify the correct VM to delete .

Thank you for your time.

What is the easiest way to connect a USB thumb drive in Hyper V version 10.0.18362.1? I need to move some info from into (Windows 7) running in my Hyper V. I have used another virtual machine and the USB would show up, you had to tell it to connect. I
cant even find it in Hyper V.

My work laptop is a Lenovo Thinkpad X1 Carbon w/16GB of Ram, 4c/4T intel 8th gen CPU, integrated GFX & SSD.

The laptop performs reasonably well and I use it for running a single VM connected to a Thunderbolt Lenovo Docking Station (that supports 4k) and a 4k DP monitor.

I connect to the VM by using VMConnect and I noticed significant lack of desktop performance (during normal usage)
only when the VM screen is Maximised.

• Why is that? Can anything be done to improve its Full Screen 4k Desktop performance?

NOTES.

- VM Resources maximised as follows:

CPU = 8 Virtual Processors (Physical CPU has 4 cores + HT).

RAM = 10752 MB - No Dynamic Memory (DynMem Disabled).

Pagefile.sys = fixed size, 4GB.

- Host Win10 Pro OS set to prioritise Background processes.

- When the VM runs on a 1920×1080 window, it is usable.

- When the VM is Full Screen, it becomes unusable (the issue occurs both On VMConnect & RDP Client).

I updated to Win10 2004 (Build 19041.208 as of this writing) and I’ve noticed that on my system with Hyper-V installed, I now have an auto-created vEthernet interface for every physical Ethernet interface on my system, including interfaces with no connectivity. 
Each one is named "vEthernet (Physical interface name)".  This is occurring despite that fact that only virtual switch I have on my host system is the Default Switch.

All of these vEthernet interfaces have auto-assigned 172.x.x.x IP addresses.  These vEthernet interfaces cannot be deleted in Network Connections (option is grayed out) and if I use Device Manager to uninstall the actual Hyper-V Virtual Ethernet adapter
device associated with these interfaces, they reappear on reboot.

Strangely, when I installed Win10 2004 in a guest VM with 3 virtual NICs and installed Hyper-V within that VM (after enabling nested virtualization), I was NOT able to reproduce this behavior. The guest VM’s Hyper-V environment did not create 3 new vEthernet
interfaces, even after multiple reboots.

Is anybody else seeing this? Does anybody have any idea why this is occurring or what the purpose of these vEthernet interfaces is?  Previously I only ever had one vEthernet interface for the Default Switch, and then I would get one more for each Internal
or External virtual switch I created. This is how another Hyper-V host system I have that’s still running Win10 1809 is working right now. I have no idea why Hyper-V now feels the need to give me one per physical interface, each with a 172 IP address.
