[Users] veth and checkpoint and restore

[Nils Domrose]

Hi Andrey,

vzctl version:
ovz1:~# vzctl --version
vzctl version 3.0.14-1dso31.2

for the kernel this is more problematic:

i noticed that i cannot provide you with the version since i  
installed this kernel
http://download.openvz.org/kernel/debian/etch/linux-headers-2.6.18- 
openvz-amd64_02_amd64.deb

cat /proc/version
Linux version 2.6.18-openvz-amd64 (02) (ola at deb-build- 
amd64.openvz.org) (gcc version 4.1.2 20061115 (prerelease) (Debian  
4.1.1-21)) #1 SMP Fri Jan 26 18:14:59 UTC 2007

problem is that the debian packet and file name does not indicate the  
version of the ovz patch - so your question was already helpfull  
since no know that I do not know which version I use ;-)

Do you think it makes sense to upgrade to the latest version 028.18 -  
I would try out:

http://download.openvz.org/kernel/debian/etch/linux-headers-2.6.18- 
openvz-amd64_028.18-2.6.18-11-1_amd64.deb

Nils
