Details

Description:

Kernel panic only happens when running Windows 10 VM. Note that nothing has changed with my KVM configuration in over a year, but this started happening when 5.5 came out but maybe earlier.

Important to note that kernel panic will not happen when no VM's are running. I've not tested other guest OSes as I only have one VM on this server, and it's not always running. But when it is running, this crash will happen usually within 24 hours and can be exacerbated by use.

Again note that my VM itself has not changed, nor has the qemu/kvm configuration in well over a year and has been working fine.

*** NETWORK CONFIG ***

I'm including this section because I ran across a similar kernel bug about 2 years ago that had something to do with the bonding driver and KVM. I've stopped using bonding for that reason, so my config is more basic now but still includes vlans:

#!/bin/bash

# Vlans this machine will participate in
VLANS="2 3 99"

if [[ $1 == "up" ]]; then
# Setup switched virtual interfaces (SVIs) using Linux software bridge for each vlan
for x in $VLANS
do
ip link add name vlan$x type bridge
ip link set txqueuelen 10000 dev vlan$x
ip link set up dev vlan$x
done

# Create a virtual switch and call it "vmbridge"
# This is an isolated network used mostly for testing various VMs/Containers
ip link add name vmbridge type bridge
ip link set address 68:09:68:09:68:FF dev vmbridge
ip link set up dev vmbridge

# Prepare physical 10-gig Ethernet port
ip link set mtu 9000 dev teng0
ip link set txqueuelen 10000 dev teng0
ip link set up dev teng0

# Add vlan ID's to pnic

do
ip link add link teng0 name teng0.$x type vlan id $x
ip link set txqueuelen 10000 dev teng0.$x
ip link set up dev teng0.$x
# Plug it into the appropriate SVI
ip link set master vlan$x dev teng0.$x
done

umount -aft nfs

# Terminate SSH sessions

# Remove virtual switch "vmbridge"

*** STEPS TO REPRODUCE ***

I just boot my KVM instance via the command line (pasted above). Crash happens usually within 24 hours and is always the same output.

This task depends upon

This happened again just now. I didn't know that the machine doesn't immediately crash - apparently it takes a few more minutes. Here's the first kernel output. Keep in mind that when I saw this, I was able to still log into the machine, shutdown the KVM, but the machine locked solid about 15 seconds after shutting down the KVM.

Note that this system also serves NFS shares.

Here's the first bit that didn't immediately lock the machine:

docdrow the latest occurrence was on a kernel with patch hetfig linked to applied?
Comment by George Shearer (docdrow) - Saturday, 18 July 2020, 13:11 GMT
Attention admin: I need to change the topic of this bug, as it turns out, KVM has nothing to do with it. After a cold boot, this crash happened and I never booted any VM's. So, it appears to be some kind of bug that has to do with NFS?

Can you confirm linux 5.7.10.arch1-1 currently in testing has resolved the issue?
Comment by George Shearer (docdrow) - Tuesday, 28 July 2020, 19:30 GMT
