I have a mixed PVE cluster; most guests are running Windows and Linux. In addition, PVE is running on an Intel MacPro where macOS is a guest. I am also running my VM with VGA passthrough on this system as a triple boot guest to macOS, Windows, and Linux.
Since passthrough and macOS require machine q35 and HA won't be available on those guests, this setup works out nicely for me.
I wanted to virtualize Android in Proxmox so I could avoid using my VM guest resources. So I have been testing Android x86 but it is currently not an ideal setup.
Some reasons include:
1. QEMU USB tablet for VNC only works properly in an old Android x86 (v 4.4 r5) and that old version does not properly handle ARM translation (to include the specific Android app I desire)
2. Android x86 has no Spice guest drivers
3. Proxmox has not implemented the QEMU Audio Extension for VNC
In scratching that pursuit for now, my next desire was to enable nested virtualization in my triple boot VM.
The Proxmox Wiki has good instructions on enabling nesting on the host PVE and for most guests.
In my scenario my macOS guest requires a Penryn CPU personality, whereas the Wiki instructs the user to set the VM CPU to host.
However a host CPU personality is not a requirement for nesting and can be enabled on other CPU personalities.
I have enabled nested virtualization by adding the VMX instruction directly to the CPU personality, editing the VM config and adding args:
My specific args for advanced CPU instructions on a working macOS et al. guest:
Now my Windows, Linux, and macOS all run smoothly with VGA passthrough and nested virtualization in a triple boot setup. I am running Nox Player emulator and it is running very smoothly.
I do hope more progress is made with Android x86 to allow other hosts in my cluster to utilize their resources for this purpose instead.
P.S. I would accept an invitation to volunteer and propose updates to the wiki article on this topic and others.
