Hi Laszlo,
That did it! Boot times are down to ~25 seconds-to-splash with 8
cores, 2 threads and 24G of assigned RAM.
Not as fast as some bare-metal machines, but far more bearable &
manageable than *minutes*!
I compiled a custom kernel (version 4.19.2) with the PREEMPT_NONE=y
(menuconfig:
Hi Laszlo,
Looks like CONFIG_PREEMPT_VOLUNTARY isn't set.
CONFIG_PREEMPT_RCU=y
CONFIG_PREEMPT_NOTIFIERS=y
# CONFIG_PREEMPT_NONE is not set
# CONFIG_PREEMPT_VOLUNTARY is not set
CONFIG_PREEMPT=y
CONFIG_PREEMPT_COUNT=y
CONFIG_DEBUG_PREEMPT=y
# CONFIG_PREEMPTIRQ_EVENTS is not set

And just a quick discovery:
With 24G assigned (-m 24576)...
Reducing the number of CPU cores to 1, 2 or 3 with
ovmf-x64-0-20181105.757.g114a75ad86 results in a really fast boot to
the TianoCore splash.
As soon as the number of CPU cores jumps to 4, the VM takes a hit in
terms of boot time.

This is an issue that involves a combination of different software
packages, so my apologies in advance if this is the wrong list to post on.
I'm experiencing terrible boot times when I assign a large amount of RAM to
a VM when used in combination with VIFO/PCI-passthrough.
On a VM with a
