qemu: Don't reset "events" migration capability
When creating v3.2.0-77-g8be3ccd04 commit, I completely forgot that one
migration capability is very special. It's the "events" capability which
tells QEMU to report "MIGRATION" events. Since libvirt always wants the
events, it is enabled in qemuConnectMonitor and the rest of the code
should not touch it.

Description of problem: Operation failed when migrate VM back to source host unless restart libvirtd Version-Release number of selected component (if applicable): libvirt-3.2.0-2.el7.x86_64 qemu-kvm-rhev-2.8.0-6.el7.x86_64 How reproducible: 100% Steps to Reproduce: 1.prepare migration env 2.start a vm on source [root@source ~]# virsh start V Domain V started [root@source ~]# virsh dumpxml V|grep graphic <graphics type='spice' port='5900' autoport='yes' listen='127.0.0.1'> <listen type='address' address='127.0.0.1'/> </graphics> ... 3.migrate from source to target [root@source ~]# virsh migrate V --live qemu+ssh://target_ip/system --unsafe --verbose Migration: [100 %] 4.try to migrate from target to source [root@target ~]# virsh list --all Id Name State ---------------------------------------------------- 22 V running [root@target ~]# virsh dumpxml V|grep graphic -A3 <graphics type='spice' port='5900' autoport='yes' listen='127.0.0.1'> <listen type='address' address='127.0.0.1'/> </graphics> ... [root@target ~]# virsh migrate V --live qemu+ssh://source_ip/system --unsafe --verbose error: operation failed: migration job: is not active 5.restart libvirtd and try to migrate back again: [root@target ~]# systemctl restart libvirtd [root@target ~]# virsh migrate V --live qemu+ssh://source_ip/system --unsafe --verbose Migration: [100 %] Actual results: As in step4, operation failed when migrate VM back to source. In step5, after restart libvirtd, the migration back operation can succeed. Expected results: VM should be migrated back to source host successfully, without restart libvirtd. Additional info:
