[one-users] Opennebula livemigrate

[Fermín Manzanedo Guzmán]

Hi all.

We're trying to implement the livemigrate feature in our ONE cluster but
don't know why it doesn't works properly:

Like readed in
https://bugs.launchpad.net/ubuntu/+source/opennebula/+bug/323359 ubuntu
use qemu+ssh for livemigrate and since 2009-02-04, opennebula use it. We
have a previous version (1.2.0) but in an attempt to solve this, change
the line

std_action("MIGRATE", "migrate --live #{args[3]}
qemu+tcp://#{args[4]}/session", args)

to

std_action("MIGRATE", "migrate --live #{args[3]}
qemu+ssh://#{args[4]}/session", args)

And restart opennebula... But still doesn't work properly.

When try to perform a live migration, we receive this:

Thu Jun  4 17:07:58 2009 [ReM][D]: VirtualMachineMigrate invoked
Thu Jun  4 17:07:58 2009 [DiM][D]: Live-migrating VM 61

Thu Jun  4 17:08:00 2009 [VMM][D]: Message received: MIGRATE FAILURE 61
Unknown failure

In our libvirtd.conf we have this options enabled:

listen_tls = 0
listen_tcp = 1
unix_sock_group = "libvirtd"
unix_sock_rw_perms = "0770"
auth_unix_ro = "none"
auth_unix_rw = "none"
log_level = 1
log_outputs="3:syslog:libvirtd"

May be we forgot any other option...

Is there any way to implement livemigrate feature in ubuntu's opennebula?


Thanks in advance. Regards
