libvirt.libvirtError: internal error no supported architecture for os type 'hvm'

[Arnaud]

vm-builder 0.11.1-0ubuntu1

This is on kubuntu karmic intel x86_64 (fresh install using alpha6 alternate CD):
Description: Ubuntu karmic (development branch)
Release: 9.10

the problem is that creating a new VM image fails when registering new VM into libvirt.

Steps to reproduce: build a new VM using the following command:
sudo ubuntu-vm-builder kvm ${release} --tmpfs=- -d test-t1 --domain=test --hostname=t1 --user=toto --ssh-key=/home/toto/.ssh/id_dsa.pub --ssh-user-key=/home/toto/.ssh/id_dsa.pub --libvirt=qemu:///system

where release is set to one of intrepid, jaunty, karmic.

Here is the output (for release set to jaunty):

virtualization was disabled in the BIOS (default settings):
kernel: [ 476.938973] kvm: disabled by bios

I think this is what caused the problem, closing...

[Thijs Thiessens (t-thiessens)]

Hey all,

The problem still exists even with kvm enabled in the bios.

I'm getting the exact same error on Jaunty on an AMD x86_64

[Andrew Bulmer (bulmer)]

Hmmmm I suspect that this may be due to the hardware virtualisation not being enabled in the BIOS. Unfortunately I don't have immediate physical access to that server to check. I only have ssh access to it right now. Anyone know a command I can run to check if hardwar virtualisation is enabled?

/proc/cpuinfo does have vmx listed, but according to the docs that doesn't mean its enabled.

[Andrew Bulmer (bulmer)]

I haven't been able to confirm that it is the BIOS setting thats the problem, but running virsh capabilities doesn't show anything for guest, and from I've found in other forums I think it should.

is it possible for vmbuilder to run "virsh capabilities" to make sure hvm is working (throwing up an error telling the user to check BIOS settings if its not) before building anything?

[Andrew Bulmer (bulmer)]

oh and it seems that this error only comes up if you use the --libvirt=qemu:///system option. So if someone uses that option the virsh capabilities needs to be checked.

[Robert Light (light-alum)]

I just added a node-controller which doesn't have a virt.accelerated processor in it and I'm getting "libvirt: internal error no supported architecture for os type 'hvm' (code=1)"

Can I use a node-controller which doesn't have virt.acceleration??

[NeilGreenwood (neil-greenwood)]

I had this same problem. kvm-ok was reporting success, but the VM creation was still failing. I had to power off the server after changing the BIOS in order for the 'hvm' type to be valid.

[Itraju Devendra Babu (itraju-babu)]

check the --libvirt-type if it is "kvm" then
change it to --libvirt-type=qemu in /etc/nova/nova-compute.conf
and reboot the machine
your bug will get resolved
