Can't vzmigrate to new container id [message #49015]

I was under the impression that you migrate to a new containerID simply by using the paramenter <oldid>:<newid> on vzmigrate, however the command doesn't recognize the parameter like that.

I'm running on a CentOS 6 machine with 2.6.32-042stab074.4 kernel.

I don't know what version of vzctl I'm running because I'm don't know how to check, if anyone can tell me how too I'd appreceate it.

To find out more about vzctl and vzmigrate, simply try (two separate commands):

man vzmigrate
man vzctl

Hi Ales,

neither of the manuals mention their versions, nor does the vzmigrate manual mention migrating to a different container ID. Yet I've seen references of this in many places using a format like this:
server@linux[~]#vzmigrate -r no 192.168.0.1 110:120

Is this option only available in a special version of vzmigrate? Where can I get it?

The manuals do not contain the version itself, but they do tell you which command switch to use to display the version Smile

vzctl --version

On CentOS you can display the installed packages by using yum or rpm, for example:

yum info vzctl
rpm -q vzctl

The vzmigrate script is also a part of the vzctl package and doesn't seem to have a separate version. Perhaps this caused some confusion...

I'm afraid I don't use vzmigrate in the way you do, so I can't help you with the migrate command itself. Someone else will hopefully be able to...

Oh, that would explain why I couldn't get any info on vzmigrate on yum.

It seems I do have the latest version, however I don't understand why the <old ctid>:<new ctid> format isn't available. Maybe the references that I saw to this were from a previous version and it has since been removed.

I'll have to look around to another efficient way of migrating under different CTID then.

Thanks for the help.
