Hello,

1.

vzdump --restore /vz/dump/vzdump-162.tar 163

What is it "vzdump"?

2.
Could you please describe your problem in more detail?
You have several dump files associated with VE 162, haven't you? Do you want to use dump file from 162 VE to restore VE with another number?
I think you could try to do it but you have to create two things for this purpose:
- private are for 163 VE (the same as 162 had during the vzdump-162.xdelta creation)

cp -a /vz/private/162 /vz/private/163

- config file for VE 163

cp /etc/vz/conf/162.conf /etc/vz/conf/163.conf

vzctl restore 163 --dumpfile /vz/dump/vzdump-162.xdelta

Thank you for your dedication to help, but you do not like the correct way.
VZdump in the introduction to this address can see. http://wiki.openvz.org/Backup_of_a_running_VE_with_vzdump Razz

Hi,

yes, my bad. I've never heard about vzdump Embarassed

But as far as I understand you should do the following:

- we suppose that vzdump-162.xdelta was created as a delta between vzdump-162.tar and newer CT 162 state.
-

# cd /vz/dump
# xdelta patch vzdump-162.xdelta vzdump-162.tar vzdump-163.tar
# vzdump --restore /vz/dump/vzdump-163.tar 163
