Correct Virtual Processor Identifier (VPID)

Hello !

Let’s say hypervisor runs virtual machine with VPIDs set to 1 for all virtual cores(Vmcs). While this hv and VM is running, I start another hv.

Will this second hv be able to generate unique VPID for VM it wants to run? If not and second hv sets VPID for it’s VM also to 1, will one of the VM use stale entries in TLB ?
