Obviously it isn't well known, but I've been using qemu, and later kvm for testing the Linux-VServer kernels since ages and naturally, those testing happens on a host also running a Linux-VServer kernel :) > Are there any problems expectet to run linux-vserver and kvm > together?

I haven't had any problems or issues with the setup for a long time and there is nothing special you have to consider. > For kvm we can use a dedicated nic to route all the traffic > separated from the linux-vserver traffic. No need for that, usually a tun interface on a bridge will give you full flexibility, but of course, you can also use a dedicated nic or whatever else you prefer.
