What happened?
When trying to start a nested virtual machine on Proxmox, the Proxmox VM crash with either VERR_PGM_MAPPING_IPE or something like "pgmR0BthEPTProtNestedTrap0eHandler: rc=0 GCPhysNestedFault=0x000000007ff3833a (0x00000001c8d38000)"
How can we reproduce this?
Install a proxmox guest, create a new virtual machine, give to the nested vm 2 cpu and start the vm. The system will crash some from seconds to minutes after.
