Hi,

we are using linux-vserver on debian since 2007 and we are very happy with it. For our
business it works
very great.

But we have some requirements to run a few fully virtualized guests like redhat or centos
where we need some specific kernels to run in the guest. This special guests don't need
many recources
so we are thinking to run it on the some server together with some of our linux-vserver
guests.

Have anyone of you experience with a setup like this?
Are there any problems expectet to run linux-vserver and kvm together?
Or are there some other better full virtualization technologies which we don't know?

For kvm we can use a dedicated nic to route all the traffic separated from the linux-vserver
traffic.

We intend to use kernel 3.10.x. It was announced as the next long term kernel:

Many thanks and regards
