Hi Dietmar,

 
after last update - right, the startup regex is fixed already...

 
please find below patch to enable CentOS 5:

More changes are not necessary. Template seems to run without problems. Template created using following commands (for those not having yum installed in debian please run “apt-get install yum”):

 
/usr/share/lxc/templates/lxc-centos -n CentOS_5_template -R 5 -p /var/lib/lxc/centos5

cd /var/lib/lxc/centos5/rootfs

tar -czf /var/lib/vz/template/cache/centos-5-default_20151018_amd64.tar.xz *

 
Start of CentOS 5 went smoothly without any visible error. “pct enter” works on console, Console Button in Interface is working, too. Network is working.  

 
If you find any issue please drop me a line and I will have a look into it.

 
Best regards

 
Andreas

Thanks, but CentOS5 require much more work, because all scripts for newer

version does not work.

The regex for centos6 is already fixed.
