Comment 0 for bug 1874453

Using `ubuntu/focal64` version `20200423.0.0`, the boot process is extremely slow and the box always reboots once before completing a successful boot. With default settings, this causes a timeout in Vagrant waiting for SSH to be available. Setting a long enough timeout it does eventually boot successfully. For comparison, `ubuntu/bionic64` boots successfully in roughly 10 seconds on my machine.

This appears to be the big hang-up:

Apr 23 14:00:12 ubuntu-focal kernel: [ 0.219784] printk: console [tty1] enabled
Apr 23 14:00:12 ubuntu-focal kernel: [ 76.448371] printk: console [ttyS0] enabled

I have a hard time telling where exactly it reboots because my /var/log/syslog only ends up with the second boot. I can watch it in Virtualbox though and it suddenly reboots, then the second boot process runs to completion. The long delay shown above happens both times making the total time to a successful boot very long. Here is the head of my /var/log/syslog:

Subsequent boots are also slow but don't seem to have the extra reboot.
