I had been fooling around with several test Windows VMs, messing with the XML, etc., and now have managed to screw things up enough that I cannot delete the VMs to start over.

 

That means I can't reuse my UUID that I need for my licensed copy of Windows, because it is currently reserved by one of these busted VMs.

 

If I try to delete any of these VMs (which are currently stopped), I get an error that:

 

Requested operation is not valid: cannot delete inactive domain with nvram

 

Is there a way to remove these manually? A config file or something on the flash drive? I located the actual VM disc image but deleting that will not remove the entry from the Unraid GUI.

 

The big problem is freeing up my UUID because it is tied to a paid version of W10, which right now is stuck on a useless VM.

Run from a shell (SSH, etc):

 

virsh undefine --nvram "name of VM"

You can also go to /etc/libvirt/qemu/ through the command line or mc and delete the vm's xml. Then restart rc.libvirt, the array or the server.

Run from a shell (SSH, etc):

 

virsh undefine --nvram "name of VM"

 

Tried that and got the same error... I assume the GUI is just running this exact command behind the scenes

 

Edit: the --nvram flag changes things, let me try again

Thank you, works great. I had to delete the vdisk from the cache after I ran the code, and voila... as if it never happened.

This helped me get rid of it as well, Thanks!! 

Had this exact error and then figured since the nvme drive is enabled and checked within the vm template to just go back to that busted or bad VM template and then uncheck NVME drive in the other pci devices section or just uncheck any usb or pci express devices and hit apply. Now you should be able to simply delete the vm without any error message.

 

Unraid is so logical that if you try to 'Windows' it, it won't forgive you for being stupid and it will just tell you off, but if you think like spock unraid just works.

 

 

Thank you kode54, this was the solution for me as well:

Thanks for this. I checked the button for my Logitech wireless mouse, updated the template, then was able to delete it without error.

Thank you guys, saved my day!

I bet your vm name is not "Macinabox BigSur of VM", but maybe "Macinabox BigSur"

Thanks

it was my first time I did this wrong. I removed the VM files but the VM still shows in the VM list an I cant remove it. Any thoughts Thanks dlfz

Type this in unraid terminal:

virsh undefine --nvram "Macinabox BigSur"

 

OMG Thank you it worked right off the Bat !!!!!!!!!!!!!!!!

How do I go about restarting rc.libvirt?
