Hello we've have about 15 low use virtual machines that I'd like to run using PVE in a kvm. like cups, xmpp, etherpad etc. My question is: Are there any reasons not to use pve within a kvm? I'll be using Turnkey openvz and later lxc in the kvm.

Thank you for the answers... Have you used nested pve on drbd or ceph? If so does migration work ?
Hi,
For training purpose we do it. Pve in Pve works fine, a 2 nodes cluster + drbd works fine and live migrate correctly, without breaking drbd!
But, l2 kvm guests does not work reliably.
Kernel 3.x is mandatory for l0 hypervisor.

thank you for the response..what is 'l2' ? [ Is it from L2 as described at : http://www.ibm.com/developerworks/cloud/library/cl-nestedvirtualization/ ? ]
Absolutely :
L0 represents the bare-metal hypervisor,
L1 the guest hypervisors,
L2 the guest VMs.
L2 without kvm acceleration is slooooooow but stable. L2 with nested kvm runs smoothly once installed, installation often leads to crashes, and I can't have a stable network config.
