libvirt users - Feb 2013 - VMs XML difinitions can't be recognized after upgrading to libvirt 0.9.13

I used to run many VMs on my Ubuntu 10.04 box. However, after upgrading to 
Ubuntu 12.10 (and thus, libvirt 0.9.13), The VMs can't be recognized
anymore.
Nothing appears in the output of 'virsh list --all', nor in
virt-manager.

When I created a new VM based on a disk image of one of the 
not-recognized-any-more VMs, a new schema file has been auto-generated, and the 
new VM now is recognized.

So, if this is caused by incompatibility with the old schemas, would the 
solution be to manually recreate all the VMs by importing their disk images to 
the newly created VMs, or is there a more intelligent approach?

Thanks for your time.

capabilities detection for qemu/kvm bits likely failed. Do you have
kvm and kvm_amd or kvm_intel loaded? Best place to start is checking
/var/log/libvirt/libvirtd.log
