Yes, you can have both hypervisor drivers running on the same machine; you choose which hypervisor you connect to according to the URI that you pass to 'virsh -c' or virConnectOpen(). > If so, can resource isolation work properly? that is, can LXC and KVM get > their corresponding shares of resources(vcpu, memeory, etc..)? > In that case, how does LXC vcpu map to cgroups cpu.shares? Yes, both LXC and qemu hypervisors know how to limit guest resources using cgroups under the hood; in particular, see http://libvirt.org/formatdomain.html#elementsCPUTuning for the XML to use. <cputune> has a sub-element <shares> that maps nicely to the cgroups cpu.shares. -- Eric Blake eblake redhat com +1-919-301-3266 Libvirt virtualization library http://libvirt.org
