Try running things under valgrind to find the culprit. If I do virsh domxml-to-native xen-xm prova.xml it works with no problems but if I do virsh domxml-from-native xen-xm backupsrv.cfg I have the error. Here is my backupsrv.cfg: # # Configuration file for the Xen instance backupsrv, created # by xen-tools 4.2 on Mon Sep 26 13:29:57 2011. # # # Kernel + memory size # bootloader = '/usr/lib/xen-default/bin/pygrub' vcpus = '1' memory = '1024' # # Disk device(s). # root = '/dev/xvda2 ro' disk = [ 'phy:/dev/vg-xen-domUs/backupsrv-disk,xvda2,w', 'phy:/dev/vg-xen-domUs/backupsrv-swap,xvda1,w', ] # # Physical volumes # # # Hostname # name = 'backupsrv' # # Networking # vif = [ 'ip=192.168.245.10,mac=00:16:3E:65:8E:86,bridge=xenbr.119' ] # # Behaviour # on_poweroff = 'destroy' on_reboot = 'restart' on_crash = 'restart'
