[PVE-User] Live-migration slowdown

[Julien Groselle]

Hello everybody,

We have installed 2 servers Gnu/Linux Debian Wheezy.
There are configured in
Cluster<http://pve.proxmox.com/wiki/Proxmox_VE_2.0_Cluster>.
Everything work just fine, but when I want to use live migration we have
this output :

*May 27 14:35:20 starting migration of VM 105 to node 'xxxxx' (IPAddress)*

*TASK OK*

In fact the migration work, but it takes more than one minute... I say like
that because I think there are a 60 sec timeout somewhere...
So my problems are :
- After the creation of the migration tunnel I have this error : *bind:
Cannot assign requested address*
Do you have any idea about this issue ?
- At *May 27 14:35:45* the remaining amount of data to sent is 0 but during
one minute, the VM is unreachable !
And i have this in the log file :
> /var/log/syslog :
WARNING: unable to connect to VM 105 socket - timeout after 31 retries
WARNING: unable to connect to VM 105 socket - timeout after 31 retries
WARNING: unable to connect to VM 105 socket - timeout after 31 retries
WARNING: unable to connect to VM 105 socket - timeout after 31 retries
WARNING: unable to connect to VM 105 socket - timeout after 31 retries
WARNING: unable to connect to VM 105 socket - timeout after 31 retries
WARNING: unable to connect to VM 105 socket - timeout after 31 retries
WARNING: unable to connect to VM 105 socket - timeout after 31 retries

During all the time until the "TASK OK"

If one of you have just one idea to resolve this, I will be enjoy to close
the proxmox chapter and start to work on the VM.
Thank you in advance.

Sincerely yours
