Live migration fails

Thanks for reporting this bug. I can't see any error messages either. To give us some more data so I can try to reproduce, can you

1. run apport-collect 820339
2. Post the .xml for the vm you are trying to migrate?

1: apport couldn't find package libvirt?

How did you install libvirt? What do

  which libvirtd
  libvirtd --version
  dpkg -l | grep libvirt

show?

I installed libvirt from the default repositories (libvirt-bin).

root@romulus:~# which libvirtd
/usr/sbin/libvirtd
root@romulus:~# libvirtd --version
libvirtd (libvirt) 0.8.8
root@romulus:~# dpkg -l | grep libvirt
ii libvirt-bin 0.8.8-1ubuntu6.5 the programs for the libvirt library
ii libvirt0 0.8.8-1ubuntu6.5 library for interfacing with different virtualization systems
ii python-libvirt 0.8.8-1ubuntu6.5 libvirt Python bindings
root@romulus:~#

In my situation I found the cause:

https://bugzilla.redhat.com/show_bug.cgi?id=499750

My hostname was different from my (reverse) DNS mapping on the destination host.

Changing my host name on the destination host fixed the problem for me.

Tim,

can you see whether Tom's fix also works for you?

(If it does, I think I still consider that a bug, but apparently upstream does not...)

We also need to figure out why apport-collect wouldn't work for you.

Yes, Tom's fix worked. Thank you.

Thanks, Tim. Until I understand better why the behavior must be so, I"m going to mark this bug as Triaged.

(Marking low priority as it does have a 'workaround'.)
