qnx vm no longer boots in proxmox 2.3

[Rob Freyder]

Greetings,

I have a QNX vm that I rarely use.
Last time I booted it was October 7, 2012 and I was running Proxmox 2.1 or 2.2 (whatever was current at that time.)

When booting under 2.3 it stops with a "mount -p: No BIOS signature in partition sector on /dev/hd0.0" error.

Any suggestions on how to get this booting again?

Many Thanks,
Rob.

UPDATE: I tried booting the original *.vmdk file I created the VM with and I got the same error.
Something has changed with QEMU Disk.
