Hi, I ahve few(3) VMS based out of ubuntu 18.04(bionic) which were all functional from at least a year now. But yesterday, one of the 3 VM stops booting up in GUI mode(F7). It ends up ina blinking curson on the screen. I can login into machine from tty1,ty2 to tty6 but not getting anything on tty7 but a blinking cursor only.

Attaching vbox logs for someone to take a look urgently.

Note: I have checked some existing issues:

  1. My host(windows 10) hypervisor is disabled.
  2. I can successfully run other 2 VMs
  3. My VM has sufficient RAM/Space(from df and free output)
  4. Virtualisation is enabled in BIOS settings.
  5. Uptodate Vbox version and extension pack.
  6. Done apt-get update from tty1 and rebooted multiple times.
  7. 3D acceleration is in disabled mode.

Please check my logs attached.

REstoring to previous snapshot worked for me, but I forgot to take current snapshot, is there a way to restore back to the original today's state(to get my lost files back ?)

Note: Yday, I have reverted my VM to previous running state and got it fully functional but again today got ubuntu software update and ran into same issue , screen kept on blinking.

@virtual_box_team Please consider this on priority

Hello vas,

You are running old version of Guest Additions (6.1.18). Please consider to update both VBox and Additions to the latest versions (currently, 6.1.26).
