For some reason the domU is still alive, 'vmstat 1' via ssh keeps running. 'xl shutdown domU' fails. It looks like the guest OS shuts down, the ssh connection gets terminated, but the domU becomes busy according to 'xl top', and never shuts down. domU.cfg looks like this: name="fv-x64-sles12sp1-clean" memory=256 serial="pty" builder="hvm" boot="cd" disk=[ 'file:/disk0.raw,hda,w', 'file:/DVD1.iso,hdc:cdrom,r', ] vif=[ 'bridge=br0' ] keymap="de" vfb = [ 'type=vnc,vncunused=1,keymap=de' ] usb=1 usbdevice='tablet' device_model_override="/root/dm.sh" The override is to make sure to use qemu-xen as included in xen-4.5 on the sending side and qemu.git on the receiving side.
