Hi Herbert, thanks for you help. Now we had few days to think about our future configuration. We decided to use a dedicated nic for kvm. Is easier to maintain for us :-) We also reverted our decision to use kernel 3.10.x. The fact that we have running production servers with kernel 3.4.45 without any problems since a few months, we would like to use the latest 3.4.x kernel. Therefore my question, can you provide a linux vserver patch for 3.4.60? Until now there is only a patch for 3.4.57 available. Only if it is not much work for you.
