Hi, I could not reproduce the bug. Could you help to provide the following information? - your host kernel/qemu/libvirt version - the libvirt xml you use to start the guest - the specific distribution of your guest - the libvirtd log For the last one, in /etc/libvirt/libvirtd.conf, set: log_level = 1 log_outputs="1:file:/tmp/libvirtd.log" Then restart libvirtd and attach /tmp/libvirtd.log. FYI, I use - Leap42.3 as the host with the original kernel 4.4.76-1-default/qemu 2.9.0/libvirt v3.3.0 && the latest kernel 4.4.104-39-default/qemu 2.9.1/libvirt 3.3.0 - ubuntu-17.04-server-amd64.iso as the guest - the same virsh command line with you
