Re: [libvirt] [PATCH 2/2] qemu: Drop default channel path during migration

Migration to an older libvirt (pre v1.3.0-175-g7140807) is broken because older versions of libvirt generated different channel paths and they didn't drop the default paths when parsing domain XMLs. We'd get such a nice error message: internal error: process exited while connecting to monitor: 2016-07-08T15:28:02.665706Z qemu-kvm: -chardev socket, id=charchannel0,path=/var/lib/libvirt/qemu/channel/target/ domain-3-nest/org.qemu.guest_agent.0,server,nowait: Failed to bind socket to /var/lib/libvirt/qemu/channel/target/domain-3-nest/ org.qemu.guest_agent.0: No such file or directory That said, we should not even format the default paths when generating a migratable XML. https://bugzilla.redhat.com/show_bug.cgi?id=1320470 Signed-off-by: Jiri Denemark <jdenemar(a)redhat.com&gt; --- src/qemu/qemu_domain.c | 43 +++++++++++++++++++++++++++---------------- 1 file changed, 27 insertions(+), 16 deletions(-)
