Limit CPU flags exposed to the VM
Hello, I'm having some troubles migrating VMs between certain Xenservers that are very similar, it's just the CPUs vary slightly. With KVM/libvirt I can limit the CPU flags exposed to the VM, how would I do the same with Xenserver? Lucian -- Sent from the Delta quadrant using Borg technology! Nux! www.nux.ro
