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
