For virt-p2v we want to get the host CPU model, topology etc, and the best way we found to do that was to pull it from libvirt capabilities[1]. Since libvirt is already parsing the host CPU information, and because /proc/cpuinfo is such a stupid format to parse, this is very convenient.
Unfortunately it doesn't work unless libvirtd _and_ KVM are both installed.
Without libvirtd installed:
# virsh capabilities error: failed to connect to the hypervisor error: Failed to connect socket to '/var/run/libvirt/libvirt-sock': No such file or directory
With libvirt-daemon installed, but not QEMU:
# virsh capabilities error: failed to connect to the hypervisor error: no connection driver available for <null>
I feel I should be able to fiddle with the connection URI in some way to make this possible, at least in the second case. However there's not a concept of "no hypervisor", and I couldn't find any other way to make it work. Using "test:///default" seems tempting, but it substitutes some imaginary host (i686) so that's no good.
Installing KVM isn't really an option for us since we are trying to build a minimal bootable ISO. Just installing qemu-system-x86_64 pulls in half the world. (Even installing libvirtd is difficult, and we'd prefer to avoid it).
Any ideas?
Rich.
