Hi all,
1, This issue is caused by the following 2 commits in upstream kernel:
9c573cd31343 randomize_kstack: Improve entropy diffusion
ef40d28f17bd randomize_kstack: Remove non-functional per-arch entropy filtering
But only virtualbox 6.1.50 will crash.
VirtualBox 6.1.x is no longer supported! Which is anounced by virtualbox.org.
So it's a bit hard to push kernel changes for an unsupported application.
I will file an upstream bug to try.
2, virtualbox 7.0.20 from virtualbox.org will work well on all the
kernel versions.
Please use virtualbox 7.0.20 if you can.

Guru meditation on VM start

Bug description:
It worked yesterday, but today I get a Guru Meditation trying to start
some of my virtual machines. This shows up in VBox.log as "VCPU0: Guru
Meditation -2708 (VERR_VMM_SET_JMP_ABORTED_RESUME)". I suspect this
may have started due to a Linux kernel upgrade I installed this
morning.
A fresh VM with no disk shows the issue. Sometimes turning off the I/O
APIC makes the issue go away, sometimes not. Turning off nested paging
sometimes lets VirtualBox make a little bit of progress w.r.t. booting
VMs, but that usually still crashes before the VM finishes starting.
This may be related to this bug reported on the VirtualBox forums:
