KVM + LXC on the same host

[ilya musayev]

We are considering running KVM and LXC on the same host and hopefully 
control both through cloudstack.

I know there are agents involved for each component, i dont know if we 
can have a hybrid of LXC+KVM.

The use case is simple, we would like the end user to pick LXC/Docker 
for performance, or KVM instance if he really needed all bells and 
whistles of dedicated kernel in fully virtualized environment.

Is anyone aware why we should not mix 2 workloads on the same host? Is 
it possible at this point in time to mix LXC, KVM and CloudStack, i 
assume the answer is no, but perhaps there is a hack i can try.

Thanks
