[SOLVED] NMIs on VE 5.1-42 and 4.15.18-4-pve

I was able to fix the problem.


- changed clocksource for VMs (clocksource=acpi_pm, was kvm_clock previously)
- on the virtualization host

/etc/sysctl.conf

# 0 avoids swapping processes out of physical memory for as long as
possible.
vm.swappiness = 0
# lessen the IO blocking effect that happens when processes reach their
dirty page cache limit in memory and the kernel starts to write them out
vm.dirty_ratio=5
vm.dirty_background_ratio=1
fs.inotify.max_user_instances = 256

/etc/default/grub

GRUB_CMDLINE_LINUX_DEFAULT="nopti nospectre_v2 noibrs noibpb l1tf=off
nospec_store_bypass_disable clocksource=acpi_pm scsi_mod.scan=sync
elevator=cfq intel_idle.max_cstate=0 processor.max_cstate=1 idle=poll
quiet"

Best regards,
Kai
