** Description changed:
I'd very much like to use the official cloud images from cloud-
images.ubuntu.com on the Brightbox cloud, but I can never get them to
boot properly in KVM.
If the disk is resized then the VM always crashes with a kernel panic.
Process is as follows:
On a Precise Host running libvirt.
- wget
http://cloud-images.ubuntu.com/quantal/current/quantal-server-cloudimg-amd64-disk1.img
- sudo cp quantal-server-cloudimg-amd64-disk1.img
/var/lib/libvirt/images/test.img
- sudo qemu-img resize /var/lib/libvirt/images/test.img 20G
- virsh create test.xml
If you view the console in virt-manager you'll find that the kernel has
panicked on the disk remount after resizing.
Issuing a 'virsh reset srv-7867c' causes the boot to progress normally.
Similarly if the disk isn't resized the boot progresses normally.
You get the same problem with:
- all the standard images - with varying degrees of feedback in the failure
message.
- using the RHEL6 version of libvirt and kvm
- if you remove the virtio from the disk stanza and replace with ide
emulation.
Any ideas?
