[libvirt] cont command failing via JSON monitor on restore

[Jim Fehlig]

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
