Hi,

the live migration fails for one of my VEs, because of an existent IPC message queue:

[root@openvz~]# vzctl chkpnt 101 --suspend
Setting up checkpoint...
        suspend...
Can not suspend VE: Device or resource busy
SYSV msgqueues are not supported, found 1
Checkpointing failed
[root@openvz~]# vzctl enter 101
entered into VE 101
[root@ve101 /]# ipcs

[root@ve101 /]#

Is there any way to workaround this issue?

Thanks in advance

Sebastian

Hello,

Currently we don't support message queues in CPT.

Unfortunately there is no way to workaround this.

We plan to add support for message queues, but we can't estimate time when this will be implemented.

Hello,

I've created a bug report at bugzilla (http://bugzilla.openvz.org/show_bug.cgi?id=583)
in order not to forget about implementing message queues migration.
Sebastian, you can add youself to CC and you'll be notifiedm when it'll be implemented.

Thank you,
Vasily.
