As soon as I enabled the serial device, given the Vagrantfile snippet, booting the system was as quick as expected. Relevant output from the serial log:

[ 0.488522] Console: colour VGA+ 80x25
[ 0.540584] printk: console [tty1] enabled
[ 0.902395] printk: console [ttyS0] enabled
[ 0.904230] ACPI: Core revision 20190816
[ 0.906123] APIC: Switch to symmetric I/O mode setup

I'm running vagrant 2.2.7 with virtualbox 6.0.14 on macOS Catalina 10.15.3 on a MacBook Pro. No real changes to Vagrantfile after `vagrant init`.

It seem like output logs to a non-attached serial device is 'expensive' where it wasn't on the bionic system. This relative old issue was recently updated with similar problems about ubuntu/eoan64: https://www.virtualbox.org/ticket/12162
