Hello,
I've installed Proxmox 3.1-3 on my HP Proliant with 12GB of RAM, 1x Xeon E5120 @1.86GHz (2 cores).
At the moment I have 5 CT and 2VM - one VM is Pfsense Gateway and another one is Windows 7 x64 HP.
On that Windows machine I've installed SQLServer 2012 Express and VNC server (UltraVNC) as well as virtio drivers.
The problem is that even in idle state, guest CPU usage is about 30-40% (proxmox reports very similiar values) and there are spikes to 100%. What can be the cause of such problem?
Here's my VM .conf file:
And here is what dstat reports when this machine is off:
And here's with Windows VM running. Look at the increase in int and csw :/
pveversion --verbose
