HI, I wanna to do some experiments about VM migration. Currently I focus on the local migration which means migrating a domain from one VM to another VM in the same host. First, I create two guest VMs, XEN1 and XEN2, on the same host. Both of guests use FC6 as the operating system. And I also selected the XEN package when I customize the FC6 installation. Then, I was trying to create another VM, XENX, which is inside XEN1. The layering relationship is like this: HOST[VM1[VMX],VM2] The host includes two VMs, VM1 and VM2. And I wanted to create another VMX inside the VM1. Since the operating system of VM1 is FC6 and XEN is an built-in application of VM1 I thought I could create VMX successfully. However it prompted: "Unable to open a connection to the Xen Hypervisor/daemon Verify that: -A Xen host kernel was booted -The Xen service has been started" Is there anything wrong with what I have done? Or currently we are not allowed to create a virtual machine inside another VM. The only possible way to create guest VM is to create it inside a physical machine, not VM? Could you please let me know if you have any idea about above problem? Thanks a lot. Regards, Angel -- Fedora-xen mailing list Fedora-xen@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/fedora-xen
