[SOLVED] Proxmox installation inside Synology Virtual Machine Manager

[Brdru]

Hello,
I tried to reinstall a Proxmox node inside a Synology Virtual Machine Manager on DS1621+ hardware.
Installation is fine, nested virtualization is detected, but at first reboot, I get a freeze on :



I tried different hardware for storage, virtio, ide, sata...

A year I remember doing the same thing without encountering any problem.

An idea ?

Hi,

What version of PVE you are trying to install?

Thanks for reply
Last one the 7.1.2. default setup

Found the problem, It's the vmvga driver from Synology Virtual Machine Manager and noVNC. It's ok with vga .

You can close this thread, thanks again.

Sorry for posting in an old post, but I'm trying to run Proxmox in a VMM VM on a ds1823xs+...I can install Proxmox, nested virtualization works, LXCs works, but all VMs in Proxmox hangs after a few seconds, sometimes I can start the installation of an OS in a VM, but VM always freezes with 100% CPU long before the installation can finish.

I have tried to restore backups and start several VMs from another Proxmox...all freezes during boot with 100% CPU. Did your VMs work? The ds1621+ like the ds1823xs+ are using an AMD CPU.

Im on DSM 7.2.1-4

I would really appreciate your input.

nested virtualization works

is very slow for VM.
LXC works flawlessy because it use Proxmox Kernel virtualized once.

How slow?
My use-case is to live migrate a couple of VMs(one of them my primary fw) from my primary Proxmox node(running on a Intel nuc 12) the few times I have to reboot it, and I dont need top-notch performance.

for me : nested is only for test & dev , you need to do benchmark/measures to confirm impact.
