I upgraded my Debian host to KVM 72 and libvirt 0.6.3-4 in the hopes of gaining use of PCI passthrough. I suspect that the upgrade may have gone a bit awry, because when I attempt to enable passthrough, I get the following error:

/usr/bin/kvm: invalid option -- '-pcidevice'

Is the version of KVM that I installed too old or is something else going on?

It is too old. That option was added in kvm-79, and there's still updates to help make pci device assignment work so moving to as recent as possible would be the right move. thanks, -chris
