As I'm deeping into the problem, your is described here
o Booting Linux using a console connection that is too slow to
keep up with the boot-time console-message rate. For example,
a 115Kbaud serial console can be -way- too slow to keep up
with boot-time message rates, and will frequently result in
RCU CPU stall warning messages. Especially if you have added
debug printk()s.

Does the VM have VirtIO serial console activated? I had the same problem
and removing that fixed it.
