Slightly offf-topic now, I suppose: you're right regarding the containers. However, if I want to run a VM in GNS3/vrnetlab, it means using QEMU - either: * QEMU in a GNS3 domU, or * QEMU in a container in a Linux domU, as seen with vernetlab In both cases I need nested HVM, to be able to use the nested VMs at a acceptable speed. Could you elaborate on what isn't supposed to work properly in Xen's nested virtualization? FWIW, it works without problems in my setup. -- Mit besten Wünschen / With best wishes, Manuel Kuklinski
