Nested-Virtualization XenServer

[r.pizarro]

I have set up an environment with a physical host running Proxmox and two additional virtualized Xen servers. The problem arises when I create individual VMs to add to the two (virtual) servers, because CPU resources are being used to their maximum capacity. What can I do to prevent this?

Hey, this looks like CPU overcommitment? How many physical cores does the host have, and how many vCPUs have you assigned to each Xen VM? Is the CPU saturation on the PVE hosts, inside the Xen VMs, or both?
