Hi Daniele, Here are the packages I started with in my test environment and what the initial instances were based on:
dpkg -l | grep qemu ii kvm 1:84+dfsg-0ubuntu16+1.0+noroms+0ubuntu14.19 ii qemu-common 1.0+noroms-0ubuntu14.19 ii qemu-kvm 1.0+noroms-0ubuntu14.19 ii qemu-utils 1.0+noroms-0ubuntu14.19 dpkg -l | grep libvirt ii libvirt-bin 1.2.2-0ubuntu13.1.6~cloud2 ii libvirt0 1.2.2-0ubuntu13.1.6~cloud2 ii nova-compute-libvirt 1:2014.1.3-0ubuntu1~cloud0 ii python-libvirt 1.2.2-0ubuntu2~cloud0 And here's the result after I upgraded the packages using the Icehouse cloud archive: dpkg -l | grep qemu ii ipxe-qemu 1.0.0+git-20131111.c3d1e78-2ubuntu1~cloud0 ii qemu-common 2.0.0+dfsg-2ubuntu1.6~cloud0 ii qemu-keymaps 2.0.0+dfsg-2ubuntu1.6~cloud0 ii qemu-kvm 2.0.0+dfsg-2ubuntu1.6~cloud0 ii qemu-system-common 2.0.0+dfsg-2ubuntu1.6~cloud0 ii qemu-system-x86 2.0.0+dfsg-2ubuntu1.6~cloud0 ii qemu-utils 2.0.0+dfsg-2ubuntu1.6~cloud0 dpkg -l | grep libvirt ii libvirt-bin 1.2.2-0ubuntu13.1.6~cloud2 ii libvirt0 1.2.2-0ubuntu13.1.6~cloud2 ii nova-compute-libvirt 1:2014.1.3-0ubuntu1~cloud0 ii python-libvirt 1.2.2-0ubuntu2~cloud0 The libvirt packages (1.2.2-0ubuntu13.1.6~cloud2), I think, are the most important part to bridge everything together. These new versions for both 12.04 and 14.04 included the compatibility for vms / instances created with older qemu versions. >From the tests I've done so far, everything looks good. I'd love to hear if you, or others, are still seeing issues after upgrading to the latest packages.
