[pve-devel] pve-manager : expose balloon to gui

[Dietmar Maurer]

What guest OS (windows version) and what binaries virtio drivers do you use exactly?

I just tested with win2008r2, and always get

> timer hasn't been enabled or guest doesn't support 'stat-free-memory'

I also run 'blnsrv -i' inside the guest, but still can't get usable values. Any ideas?
