[pve-devel] [PATCH qemu-server 3/8] meta info: also add current pve-machine version

[Dominik Csapak]

when we bump the pve machine version, we also want to include that info
in the meta creation info. With that we can pin guests to the specific
version they were created on.

we could also give the kvm_version as parameter directly here, since
we already need it...
