hey,
I am seeing a similar issue but only when using the kernel 5.10.0-15-amd64 on the virtual host.
If I run the following setup then everything is OK Host: 5.10.0-14-amd64 (version '14' kernel) Guest: 5.10.0-15-amd64 (version '15' kernel)
so, i tried the same kernel versions in the host and guest, respectively, and everything seems to be fine, so far...
i still get the occasional Jul 05 10:39:28 vmguest kernel: hrtimer: interrupt took 92917571 nskernel message, but otherwise it's quiet, and no more random process crashes.
so, this seems to be an issue introduced by kernel version 5.10.0-15. do any kernel maintainers read this list? or where do i file a bug report? greetings...
