Hi UnRAID Experts,

 

I don't know what changed but suddenly all my VMs and even new VMs won't boot after installing a 10Gb NIC card and a Graphics Card into my UnRAID PC.

I've tried to install several Linux distros but none seems to work. The VM says it has started but VNC can't connect.

 

When accessing the LibVirt logs (in Settings -> VM Manager), I get the following messages:

2024-10-11 14:20:06.216+0000: 16843: error : virNetDevSendEthtoolIoctl:3039 : ethtool ioctl error on vethdbfc709: No such device

2024-10-11 20:35:09.481+0000: 16740: warning : virProcessGetStatInfo:1755 : cannot parse process status data

 

What's wrong? 

Can anyone help me discover what is the problem?

Did you have any devices bound to vfio? Adding cards will change PCI IDs. 

 

Post diagnostics. You can delete the vfio cfg file in /boot/config and reboot to remove bindings.

There are no files named vfio.cfg in /boot/config.

Sorry, but I'm still a noob in UnRAID...

 

See attached file for diagnostics.

Looks like the VM is trying to use virtbr0 but you dont have bringing enabled. Change the VM nic to you the vhost interface. network source

Hi Simon,

I've tried both vhost0 and vhost1. None seems to work.

 

Here are the Libvirt logs:

Any other suggestion?

 

 

I still can't run any VM.

Can anyone else help me with this issue?

 

Regards.

Only other thing would be to try with a new image file to see if that fixes the issue.

 

create a disgnostic file as this will have the XMLs for your VMs.

 

Stop VM Manager

 

From the cmd line mv /mnt/user/system/libvirt/libvirt.img /mnt/user/system/libvirt/libvirt.img.old based on your image file.

 

Goto settings and then recreate image, Start VM manager a create a new VM to see if that works.

Hi Simon,

 

I've already backed up all my VM's and deleted them all in UnRAID to start from fresh.

Then I've moved the libvirt.img as indicated.

Started VM Manager again. It created a new image file for libvirt.

 

And I've tried to create several VMs (Windows and Linux). But all of them doesn't connect with VNC.

 

 

This is the Windows VM log:

 

I just don't know what else to do!

All this happened since I've installed a 10Gb NIC and a RTX 3090 graphics card.

 

All docker containers are working fine, only the VMs are not working.

 

Thanks for all your help.

Is this normal?

 

Hi,

This issue persists. Can anyone help me?

I still can't run any VM on UnRAID.

 

Regards

Problem solved in this thread.
