--- Comment #1 from Frantisek Sumsal (franti...@sumsal.cz) ---
Few additional notes:

 * this seems to happen only with nested KVM
 * all affected machines are booted with -smp 4 or -smp 8
 * this used to work (and still works) as expected with kernel 5.7.12
 * both the VM and the host use the same package set
 * an example QEMU command line from one of the failing runs:

/sbin/qemu-system-x86_64 -smp 4 -net none -m 2048M -nographic -kernel
/boot/vmlinuz-linux -drive
format=raw,cache=unsafe,file=/var/tmp/systemd-test-TEST-01-BASIC_sanitizers-qemu/basic.img
-initrd /var/tmp/initrd-testsuite-kBq.img -machine accel=kvm -enable-kvm -cpu
host -append ' root=/dev/sda1 rw raid=noautodetect rd.luks=0 loglevel=2
init=/usr/lib/systemd/systemd-under-asan console=ttyS0 selinux=0 
SYSTEMD_UNIT_PATH=/usr/lib/systemd/tests/testdata/testsuite-01.units:/usr/lib/systemd/tests/testdata/units:
systemd.unit=testsuite.target systemd.wants=testsuite-01.service
systemd.wants=end.service  '
