custom OVMF Bios

[Spiros Pap]

Hi all,

I want to run a virtual Nexus 9K (cisco switch) on my Proxmox. There is an qcow2 image that I have used to create a VM in proxmox.

The GNS3 project (network simulation) also provide a OVMF-20160813.fd file that I understand it is the UEFI BIOS that the VM must boot from.
https://docs.gns3.com/appliances/cisco-nxosv9k.html

I have selected OVMF in BIOS options of my VM. The question is how can i use the provided OVMF file, for this VM, instead of the default one. Any ideas?

Thanx,
Sp

look at the generated qemu commandline with 'qm showcmd ID --pretty' and identify
the lines which include the ovmf images (should look like '-drive if=pflash,unit=...' )

adapt those lines and add it in the 'args' of the config ( see man qm)
now disable ovmf again in the config

Hi,

Black magic. It worked. Here is what i did:
I added the line :
drive 'if=pflash,unit=0,format=raw,readonly,file=/mnt/pve/useful/OVMF-20160813.fd'
in /etc/pve/qemu-server/176.conf .

Still complains about a ton of things, but i can get into a bootloader (see below).
Then I do:
loader > boot nxos.9.2.3.bin
and voila!

Many thanx!
