[PVE-User] nested Virtualbox in proxmox takes full capacity

[IMMO WETZEL]

Hi folks,

I do have a proxmox server running with an vm (centos ) with nested Virtualbox VM.
But the VirtualboxVM takes all cpu power she got (two cores). This isn't happen if the vm runs on a Vboxhost on native HW.

Anything you propose to bring the full power to the Vbox vm ?

Nested is set on the real host
KVM Hardwarevirtualization is set to yes
CPU type is set to host

VirtIo is off on Virtualbox (on doesn't change the behavior)
Nested pages off on Virtualbox (on doesn't change the behavior)

Regards
