How to take dump of a vps?

 vzdump vid

While using the vzdump command I got the below given error :

Can’t locate PVE/VZDump.pm in @INC (@INC contains: /usr/lib64/perl5/site_perl/5.8.8/x86_64-linux-thread-multi /usr/lib/perl5/site_perl/5.8.8 /usr/lib/perl5/site_perl /usr/lib64/perl5/vendor_perl/5.8.8/x86_64-linux-thread-multi /usr/lib/perl5/vendor_perl/5.8.8 /usr/lib/perl5/vendor_perl /usr/lib64/perl5/5.8.8/x86_64-linux-thread-multi /usr/lib/perl5/5.8.8 .) at /usr/sbin/vzdump line 27.
BEGIN failed–compilation aborted at /usr/sbin/vzdump line 27.

Solution :

 ln -s /usr/share/perl5/PVE/ /usr/lib/perl5/5.8.8/PVE

After that take the dump of the vps again using the command vzdump vid. The dump will get created in the /vz/dump partition.

When it gets completed we need to scp the vps dump to the Node were we wants to restore it.

How to restore a vps?

  vzrestore vzdump-777.tar 160, where 160 is the VID of the vps to which we are going to restore.

After migration the VPS was not listing in the Hypervm.

 >> Stop the vps which was migrated.
 >> Move the conf file of the vps from /etc/vz/conf
 >> Move the vps data also from /vz/private to avoid conflicts.
 >> Create vps from hypervm
 >> Move back the data and conf of the vps.
 >> Restart the vps
 >> Migrated vps will appear in the Hypervm.
