[libvirt] cont command failing via JSON monitor on restore

libvirt 0.8.7 qemu 0.13 I'm looking into a problem with qemu save/restore via JSON monitor. On restore, the vm is left in a paused state with following error returned for 'cont' command An incoming migration is expected before this command can be executed I was trying to debug the issue in gdb, but stepping through the code introduces enough delay between qemudStartVMDaemon() and doStartCPUs() that the latter succeeds. Any suggestions on how to determine when it is safe to call doStartCPUs() to prevent the above error? I don't see this issue with the text monitor btw. Thanks, Jim
