Cannot add any virtio discs in virt-manager, how to fix?

  • 772

I’ve just freshly installed virt-manager and libvirt-bin (and related packages) on a Debian sid system, and have a strange problem I’ve not yet seen on another similar installation:

When creating a new VM, I get presented one with an IDE disc and an RTL8139 NIC. I can change the type of the NIC to virtio, no problem, but I cannot add a virtio disc. All I get offered are IDE disc/CD, Floppy, SCSI disc, USB disc.

How to fix this? Am I unexpectedly missing any supplementary packages?

Clarification: I’ve got a disc image which I can add to the VM, no problem, just I’d like to add it as virtio disc, not as IDE disc. No filesystem permission problems or anything.

  1. I just had the same problem and came up with this solution:

    Check: Is kvm really enabled in your bios?? Run this: dmesg | grep kvm

    If it says kvm: disabled by bios go to the bios and enable it! in virt-manager you can now select kvm as emulator for new machines. I just recreated my machine without modifying the image and now virtio is available for disks.

    What confused me for quite a while is that vmx is shown in /proc/cpuinfo even if VT is disabled in the bios so I did not check there first.
