nested virtualization with VMwareWS Pro

[viklander]

Good day all

I have a set of VMs migrated from ESXi to PVE 9.0.3
Those VMs have also some VMware WS Pro VMs

I just noticed that I can't run any VMware WS on the PVE hosted VMs,

When I try to run a VM from the WMware WS console, I have
a first error windows "VMware Workstation and Hyper-V are not compatible"
then a second "transport VMDB error (14), pipe connection has been broken"

However Hyper-V is definitely not enabled of the Winwdows VM hosting the VM I'm attempting to start.

I have checked that the nested option in PVE is activated ( root@proxmox:~# cat /sys/module/kvm_intel/parameters/nested Y)

And it was working when the VMs were hosted on the ESXi (I restarted the old ESXi server and double checked).

Also note that I can create a fresh VM from the VMware WS console, but I cannot start it either.

For information 'host' VMs run Windows 10 1809 LTSC, and VMware WS VMs run W10, Ubuntu or Kali : I cannot start any of them

So I'm stuck here and in a bit of trouble, if anybody has a hint or an explanation I'd appreciate it a lot

Thanks a million in advance,

Christophe

Hi,

thanks a million, but this option is not available among all the xtra CPU flags on my environment : which version are you running ?

nested-virt is available by default with host vCpu , has it changed since PVE9 ?
