Comment 49 for bug 1848534

I created a Ubuntu 19.10 VM via "Quick Create..." and still can not reproduce the long delay of > 1 minute: the VM can boot up to the Xorg GUI desktop in 26 seconds.

My Windows 10 has the same version info: Version 1909 (OS Build 18363.778).

At the grub screen, can you press 'e' and, manually edit the kernel parameter: please remove the "quiet splash $vt_handoff" and add "ignore_loglevel sysrq_always_enabled". You may want to enable the serial console logging by adding the kernel parameter "console=ttyS0", and attach putty (Run as Administrator) to the named pipe \\.\pipe\debug_slow_vm, assuming you configure the VM serial console by "Set-VMComPort -VMName your_vm_name -number 1 -path \\.\pipe\debug_slow_vm").

This way, you should get more messages on the VM serial console when the VM boots up. When you see the long delay, you can press SysRQ+w (i.e. the Right Alt + SysRq + w) to show the blocked processes, if any. This may provide more info about the long delay. BTW, here I assume your have a keyboard that has the SysRq key. :-)

It looks systemd can be configured to use "--log-level=debug --default-standard-output=kmsg --default-standard-error=kmsg", which may provide more info as well, if we check 'dmesg' and/or the VM serial console.
