PROXMOX: How To Increase Initial Boot / Startup Screen Default Time In Console For VM (To Get to BIOS, Firmware & Other Device Settings)?

Below are steps to Increase Initial Boot / Startup Screen Default Time In Console For VM (To Get to BIOS, Firmware & Other Device Settings) in Proxmox Virtual Environment

1. Identify the ID of the VM, for e.g. 101

2. On the Proxmox Host, go to /etc/pve/qemu-server directory and look for VM ID conf file.

ls -lrt /etc/pve/qemu-server/*

-rw-r----- 1 root www-data 589 Dec 11 12:15 /etc/pve/qemu-server/100.conf

-rw-r----- 1 root www-data 626 Dec 12 13:30 /etc/pve/qemu-server/101.conf

3. Edit the VM ID conf file and update the args as follows shown in bold large. In this example splash-time of 20000 is milliseconds which is 20 seconds

agent: 0

args: -boot menu=on,splash-time=20000 -vnc 0.0.0.0:15
