[pve-devel] [PATCH qemu-server] api: vmlist: add plugged cpu count to vmlist table

[Daniel Herzig]

I just tested this patch and think it gives very valuable information.

One thing I noticed, more by chance than intentional -- if the host has
a lower cpu-count than the count configured for the VM, the stats will
not be updated. E.g. my pve-host only has 2 cores available and if I
configure 4 cores for the VM, `qm list` will still show 2 cores,
although the VM is actually configured in an unbootable state.

Do you think it's possible to render something like '$NUMBER:
too_many_for_this_host' (or something similar) in this edge case?
