I just tried to change the memory for my F11 xen guest from 512 to 1024. After executing: xm mem-set workstation 1024 xm list shows the memory still being 512. Anyone else see this behavior before? I tried other values as well - but the memory is still what it was when I created the VM... I'm running CentOS 5.4 on an i386... Scot P.
