Bug ID: 216349
Summary: Kernel panic in a Ubuntu VM running on Proxmox
Product: Virtualization
Version: unspecified
Kernel Version: 5.15.39-3
Hardware: Intel
OS: Linux
Tree: Mainline
Status: NEW
Severity: normal
Priority: P1
Component: kvm
Assignee: virtualization_kvm@kernel-bugs.osdl.org
Reporter: jdpark.au@gmail.com
Regression: No
Hi,
I've experienced quite a few kernel panics over a week or so on a VM running on
a Proxmox server. I've also experienced the same issue on a pfSense VM running
on the same Proxmox server but haven't been able to capture a log from that VM.
Host details:
Proxmox 7.2-7
Kernel: 5.15.39-3
CPU: Intel N5105
VM Details:
Ubuntu 22.04
Kernel: 5.15.0-46-generic
The VM freezes and becomes completely unresponsive. I have to do a hard reset
on the VM in order to recover. Nothing is logged to dmesg or syslog so I set up
netconsole to log to a remote server and added:
GRUB_CMDLINE_LINUX_DEFAULT="debug ignore_loglevel" to grub.
Below is the output of the panic. Please let me know if there's any more
information I can provide.

Are you doing live migration? And if so, between which host CPUs?

> Are you doing live migration? And if so, between which host CPUs?
Thanks for your response. No, I'm not performing any migration. The VM is
static and only running Docker. The host CPU is an Intel N5105. It's not doing
anything too intensive with VM CPU sitting at around 10% and the Host CPU
sitting at around 5% (powersave governor set).
The CPU governer was initially set to 'performance' which I've since changed to
'powersave' using the intel_pstate driver but this hasn't improved the
situation.
There's quite a few people on the Proxmox forums (links below) running the same
CPU who have also encountered the same issue. Could there be an issue with the
kernel and this particular CPU?

I'm not sure how verbose I should be in the bug report but I thought it would
be worth mentioning that in attempting to troubleshoot, I changed the machine
type in Proxmox from i440fx to q35 but this made no difference, I got another
kernel panic today using q35 but unfortunately I forgot to change the interface
in my netconsole config so I didn't get any log of the panic. I've taken a
screenshot of the console and uploaded it anyway.

Hi John,
Thanks - hmm ok, if it's not migration it's unlikely the one I'm working on.
I doubt changing to q35 will make much odds.

OK, thanks anyway David.
Is there anything else I can do to help someone diagnose this issue? Should I
keep uploading logs of kernel panics on the VM? I apologise if these are stupid
questions but I haven't logged any kernel bug reports and I want to provide as
much information as possible.
There's quite a few people effected by this issue as demonstrated in the links
to the forum threads above.

Could you try a new (5.19 for example) kernel and also try an older kernel to
try and see if this is a regression.

We're attempting to move to the mainline kernel at the moment and we'll test
older and newer kernels and see what the results are.

There are a lot of people reporting this issue on the Proxmox forum and I am
one of them.
Tried 5.19.16 kernel a few days ago, it behaved a lot better than 5.15. Guest
kernel panic after 3.5 days instead of a few hours, but still happens.
There are reports of 5.13 being unaffected, ie, problem started from 5.15. But
I can't personally confirm this.
