Installation problems with PVE ISO on ventoy

Installation problems with PVE ISO on ventoy

[Udo Pütz]

Hi,
I did an installation on a machine over the weekend and (re)found 
something interesting: I store the pve installation ISO on a usb drive 
with ventoy. (Ventoy enables a usb drive to host several ISOs and 
present them when you boot).

The installation comes up, the installation looks good but upon the 
reboot afterwards the machine hangs with "Kernel Panic! ... VFS: Unable 
to mount root fs on unknown-block(0,0)"

I have had similar problems before with the 8.x ISOs where the 
installation ISO (on ventoy) didn't even boot up. Back then I chose 
debian and installed Proxmox afterwards.


After I wrote the ISO onto a usb drive by it's own (so no ventoy) the 
installation went smoothly and the machine bootet up correctly after the 
installation.

Both times I chose ZFS Raid1 for the two internal Samsung SSDs and 
de-selected the usb drive that showed up in the ventoy case.
