Hello setrox,

how much memory did you define for the VM? Min/max or just fixed size?

Kind regrads

Re: High Virt and Res Usage in proxmox kvm

i only use IDE disk and 2gb fixed and i see this problem again. ram usage very high 10-11GB page memory cache or something i dont know.

I also can imagine that´s something with caching - what happens if start more machines, do you run in trouble because of lack of resources? If not - don´t worry ;)

In principle I observed something similar in case of windows: process kvm uses much more memory that assigned to guest as seen in the "Summary" graphs (in my case the difference is 1GB). Moreover I saw that the windows graphical adapter consumes a lot.

But these are just observations - maybe somebody has a deeper knowledge how kvm works ....

All the best

i found my problem. This is a bug. i need sound card in xp. if i use

Code: 
args: -device AC97,addr=0x18
or
Code: 
args: -device intel-hda,id=sound5,bus=pci.0,addr=0x18 -device hda-micro,id=sound5-codec0,bus=sound5.0,cad=0 -device hda-duplex,id=sound5-codec1,bus=sound5.0,cad=1
vps using high memory. i removed this in conf file. This problem gone.

Thanks
