Pardon my dyslexia ...

"adsv1" instead of "advs1".

And it works:

:/etc/vservers/ldapappv1# vserver adsv1 start

   ...done.
 * Starting OpenBSD Secure Shell server sshd
   ...done.

THANKS A LOT!

Now, I would have another question but I think I should start a new topic as it involves OpenVZ <> Vserver import/export (Network issue).

Thank you for your very fast reply!

The config is there :

root@buapp2:/etc/vservers# du adsv1/ -h | tail
8,0K adsv1/apps/init
12K adsv1/apps
20K adsv1/interfaces/0
24K adsv1/interfaces
12K adsv1/uts
20K adsv1/scripts
96K adsv1/
root@buapp2:/etc/vservers#

However when issuing "vserver advs1 start" I get the following:

Can not find a vserver-setup at '/etc/vservers/advs1/'.

Possible solutions:
* fix the spelling of the 'advs1' vserver name
* read 'vserver advs1 build --help' about ways to create a new vserver
* see 'vserver --help' for the syntax of this command

If I compare this folder w/ another similar VPS (one that is up/listed under vserver-stat), it seems that both configs are "the same":

The configuration for Linux-VServer guests is usually stored in /etc/vservers/<guest-name> so given that the config for the advs1 guest is still there, a simple

 vserver advs1 start

should suffice to start the guest :)

If your config is broken or missing, it really depends on what the guest did and what you still know of the correct configuration.
