Description Pavel Lisý 2011-01-17 18:50:02 UTC

Description of problem:
Host system RHEL6, guest system is RHEL5, guest system is set in autoboot state.
When I reboot host system guest system stays paused. I suppose it should be running.

Version-Release number of selected component (if applicable):
libvirt-0.8.1-27.el6.x86_64

How reproducible:
always

Steps to Reproduce:
1. install RHEL5 guest system
2. set is autobooting
3. reboot host system
  
Actual results:
guest system is paused

Expected results:
guest system is running

Additional info:

virsh list
 Id Name                 State
----------------------------------
  1 hosea                paused

In /var/log/messages I can see error:

libvirtd: 19:20:12.055: error : qemuMonitorJSONCheckError:316 : internal error unable to execute QEMU command 'cont': An incoming migration is expected before this command can be executed

I can resume it: 
virsh resume hosea

than uptime is longer than uptime of host (I suppose it is intentional)

uptime 
 19:44:51 up 4 days,  4:37,  1 user,  load average: 0.49, 0.11, 0.04

Comment 1 Pavel Lisý 2011-01-17 18:51:56 UTC

Correct version of RHEL is 6.0

Comment 3 Pavel Lisý 2011-02-02 14:30:36 UTC

Ping. Is somebody reading this?

Comment 4 Eric Blake 2011-02-02 14:56:44 UTC

Yes - in fact, this sounds suspiciously like this upstream patch is the solution:

Yes, you can find some pre-release packages for testing at

Comment 9 Pavel Lisý 2011-02-07 12:51:10 UTC

Perfect. 

I've updated libvirt from this source and it is working now! All guests have been resumed correctly after reboot. Thanks a lot.

Verified as Passed in below environment:
# uname -a

Steps:
1. # cat /etc/sysconfig/libvirt-guest
make sure the ON_BOOT=start,ON_SHUTDOWN=suspend

2. Make sure the guest is in running status, also do some operations in the guest. 

3. Reboot the host,check the guest status and log.
# virsh list --all

----------------------------------
  1 libvirt5             running

# virsh list --all
