#38 New install mode grub menu entry with serial console enabled
Opened a year ago by lkocman. Modified 11 months ago

Hi,

booting the latest openSUSE Netinstall in a VM on an openSUSE based KVM host, the installer does not load if no VGA adapter is attached, i.e. the boot is happening in Serial Console mode.
Whilst in UEFI mode (tried with different OVMF EFI files) it gets stuck upon choosing the Install option in GRUB at "Loading initial ramdisk...", in Legacy/BIOS mode, after applying the solution shown in https://www.suse.com/support/kb/doc/?id=000019728, it gets suck at a black screen upon typing 'linux' as the GRUB boot option.

The following kernel/linuxrc parameters have been attempted with no change in outcome:
dis_ucode_ldr
textmode=1
splash=verbose

The removal of the set gfxpayload=keep line has been attempted with no change in outcome.

The serial device being used is the default that is set in the openSUSE Leap 15.3 VM template XML:

<serial type="pty">
  <source path="/dev/pts/7"/>
  <target type="isa-serial" port="0">
    <model name="isa-serial"/>
  </target>
  <alias name="serial0"/>
</serial>

Are further options required for openSUSE/SLES to boot the installer in serial mode?

Cheers,
Georg


We definitely need to document this also on openSUSE wiki, and I think the menu option with proper console params console=tty0 console=ttyS0,115200 should be easy to add.

Let's do a simple research around other distributions otherwise documenting this on our openSUSE wiki is a must have. Also it should be in our getting started guide that is part of openSUSE Leap box.
