Hello,

I have several install of Proxmox 3.4 in my school, and I want to upgrade all to 4.x, but I need to simulate the upgrade for testing purpose.

So, I have installed in my home Proxmox 4, and inside a VM Proxmox 3.4. Nested Virtualization is on on Proxmox 4, and the VM Proxmox 3.4 just run as it should.
I restored 2 VM from the school successfully, but this 2 VM just hang on boot : "Press F12 for boot menu".
I found no error in /var/log/syslog or in /var/log/vzctl.log.

I also tried to change the boot order, and to boot from an iso ( supergrub ), with the same result.
It seems that the VM don't recognize any media to boot.

Any suggestion to help me ?

Thanks
