Nested virtualization?

[sdetheridge]

Does anyone know if it's possible to get nested virtualization working under VMM? I've installed an evaluation of Windows Server Core and it works, but when I enable Hyper-V and reboot the guest VM blue-screens on boot.

I can't see any options for VT-x or similar, so I'm guessing that this probably is not possible -- but I'm wondering if anyone has managed to get it to work?

Not supported, no

I created a cron job to run a shell script
sudo modprobe -r kvm_intel
sudo modprobe kvm_intel nested=1

What virtualization solution are you running, if I might ask ?
I am trying to run (nested) ESX but can't seem to have a recognized network adapter.

I've installed Proxmox 8.1 on VMM (ds1823xs+/DSM7.2.1) with
modprobe -r kvm_amd
modprobe kvm_amd nested=1
and Proxmox installed just fine.

LXCs working perfectly, but VMs hangs short after boot. I dont get no error logs so I dont know(yet) what the problem is.

Did some more testing with a Debian(12) VM on VMM(ds1823xs+/7.2.1) where i created another Debian(12) with virt-manager(qemu/kvm)...did not work. Im sure Synology has done som "magic" to prevent us from running other hypervisors on their HW to force us to buy silly ass expensive VMM-licenses to be able to do live migrations etc...yuck!

Interesting.
Is there a formal statement from Synology on that topic ?
