Re: [libvirt] Trouble booting Xen VM with NFS root file system

Hi, I'm currently trying to boot a Xen VM with the root file system on NFS via libvirt. Previously we used a small python script and "xm create" to boot a number of VMs (which worked fine). Now I'm trying to integrate that functionality in a python project which uses libvirt, but sadly booting the VMs fail. The small script constructs a Xen command line which looks like the following: create =("/usr/sbin/xm create /foo.cfg \ kernel=%s ramdisk=%s memory=64\ root=/dev/nfs nfs_server=%s nfs_root=%s name=%s vif='mac=%s'\ dhcp='dhcp' vcpus=1 extra='init=/stateless.sh xencons=tty1'\ ")%(vm_kernel, vm_ramdisk, vm_nfs_server, vm_nfs_root, hostname, vif) kernel and ramdisk are the path to the installed version, vm_nfs_server is the IP address of the NFS server and vm_nfs_root the path to the operating system installation (which is a Debian Linux). Firing up the script brings up all VMs with a read-only NFS root file system. Now I tried to do this with libvirt, but all attempts failed with the following error popping up after the VM boots (after a certain time(out)):
