Happy to report that it worked perfectly. VM booted without an issue.

@AtaxyaNetwork
Thanks for such quick compile.

No problem I’ll update when it’s done and working.

@AtaxyaNetwork Sure I can test and I'll report back if it was successful.
Thanks a lot.

@KPS Glad to hear

@KPS said in Linux VM (Ubuntu 22.04) - Grub-Menu invisible:

GRUB_TIMEOUT_STYLE

Set it to menu

If ‘GRUB_TIMEOUT_STYLE’ is set to ‘countdown’ or ‘hidden’, the timeout is instead counted before the menu is displayed.

I'm not sure to why you are setting up serial connection?

@KPS said in Linux VM (Ubuntu 22.04) - Grub-Menu invisible:

GRUB_TERMINAL="serial"
GRUB_CMDLINE_LINUX="console=tty0 console=ttyS0,115200"
GRUB_SERIAL_COMMAND="serial --speed=115200 --unit=0 --word=8 --parity=no --stop=1"

I'm pretty new on XCP-ng... but I'm pretty sure the "console" of a VM is not a "serial console".

FYI, this is my /etc/default/grub

GRUB_DEFAULT=0
GRUB_TIMEOUT=5
GRUB_DISTRIBUTOR=`lsb_release -i -s 2> /dev/null || echo Debian`
GRUB_CMDLINE_LINUX_DEFAULT="quiet"
GRUB_CMDLINE_LINUX=""

2 ideas:

• What is the value of GRUB_TIMEOUT_STYLE?
• Do you have a GPU connected? it's a shot in the dark but I got this kind of issue because of GPU drivers... but on bare-metal machines

Hi,
Have you run sudo update-grub after changing your configuration?

@AtaxyaNetwork seems to work fine. I can mount my VMFS6 and the conversion is in progress.
Do you need specific test?
Note: did it on a fresh install of XCP-ng and after a yum update.

You're right. It's certainly easier that way
