[one-users] live-/migration not working, uknown error

[Adnan Pasic]

Hello everybody,
a new day, a new issue :)
I was able to successfully create my cloud and connect the clusternodes to my front-end. Even the test-VM "ttylinux" is running as expected on one of the nodes. Or so it seems... 

The problem I am having right now is, that when I start a migration or live-migration I get the following errors:

Tue May 24 12:58:32 2011 [LCM][I]: New VM state is MIGRATE
Tue May 24 12:58:33 2011 [VMM][I]: Command execution fail: 'if [ -x "/var/tmp/one/vmm/kvm/migrate" ]; then /var/tmp/one/vmm/kvm/migrate one-16 192.168.0.3; else                              exit 42; fi'

Tue May 24 13:01:17 2011 [LCM][I]: VM is suspended.
Tue May 24 13:01:17 2011 [DiM][I]: New VM state is SUSPENDED

As you can see in the log, I first tried to do a live-migration and then a normal migration right afterwards. unfortunately, both tries ended unsuccessfully.
I was searching for an error, but all I could find was one strange thing: When I initiate a "virsh list" on the node where the VM is running, I don't get any results.
Could this be the problem? And if so, how could I resolve it???


Thank you!
