[Vserver] Cloning a vserver
Hello, I hope not to disturb with a low-level question, I still hope will be useful to others. I'm very happy with my vservers in general, I must say, and the users too, of course. I want to copy a vserver into a second one, because the second one will run the same software. So I had an IP .xxx and a name old And I want a new IP .yyy and a new name new 1) I copied all the /vservers/old to /vservers/new 2) I copied all the /etc/vservers/old to /etc/vservers/new and also /etc/vservers/old.conf to /etc/vservers/new.conf 3) I went into /etc/vservers/new.conf, into /etc/vservers/new, into /vservers/new/etc and change there every string .xxx into .yyy, and old into new 4) I fixed the /etc/vservers/new symlink Now both vservers can start and stop. I can ping both IPs. But if I enter new I am in old.

Re: [Vserver] Cloning a vserver
Hi Odile, you might have missed out on the vserver hostname. You should specify new in /etc/vservers/new/uts/nodename All the rest seems fine to me but I might also be missing something obvious, Good luck to you, Youri Odile Bénassy wrote: Hello, I hope not to disturb with a low-level question, I still hope will be useful to others.

Did you change the context id of the new vserver ? It is defined in the file /etc/vservers/new/context.

Re: [Vserver] Cloning a vserver
Hi,Have you changed the context numberin /etc/vservers/new/context?As I had lots of trouble changing config stuff when copying, I have a personal way for copy/duplicate:-make a new vserver skeleton named new with right ip, context, etc that way: vserver [name] build -m skeleton --hostname [hostname] --interface eth0:[ip] --context [context number]-Copy old to new:cp -a /vservers/old/* /vservers/new/-make the dummy interface in /etc/vservers/new/interfaces to have 127.0.0.1-change config files in /vservers/new/etc/ to fit new ip and hostnameThese steps can be handled by scripts...I am making a report about vserver (in french, with details about installation and management) and should be able to put it online soon, I'll let the list know.

Re: [Vserver] Cloning a vserver
Yes you can leave it without, but in this case if you defined it in the old vserver you would have to change it in the new vserver. Also, I do not know if this is really the case, but I felt that having fixed context IDs is much more stable than having dynamic ones. - Original Message - From: Youri LACAN-BARTLEY [EMAIL PROTECTED] To: vserver@list.linux-vserver.org Sent: Tuesday, June 27, 2006 10:15:43 AM GMT+0100 Subject: Re: [Vserver] Cloning a vserver IIRC, there is no need to manually specify the context ID ...

Once again thanks Daniel. Further fiddling makes me think for our purposes that internalizing package management isn't a good idea at this time.

I'll look at this. I was thinking I was missing somethink like this. I just couldn't track it down.
