[64 bit] KVM Memory usage

view full story

http://ubuntuforums.org – Hi there, I'm seeing some high memory usage and was wondering if it was normal. I'm running 2 VMs on my Ubuntu 12.04 (server edition) : 1) Windows 2008R2 server which has 2048MB assigned to it. 2) Ubuntu server edition 12.04 which has also 2048MB assigned to it. in TOP I get 2 processes : The first kvm process (windows 2008R2) uses about 2G of memory. But the second kvm process (Ubuntu 12.04) uses more than 4G of memory. 2.03G in SWAP and 2G in RES.. Isn't that quite high for a simple lamp stack running a few websites ?
