VM freezes irregularly

[Neobin]

Could it be, that your cam-local-storage is simply full? (I guess, the VM in question uses this additional storage?) And therefore you get the io-error?
At least, by looking at the little indicator beside the storage, it looks quite(/too?) full...

You can try to change CPU type. I my case some VM need to use Host CPU

It is actually already on the Host CPU type

It seems that way. It got full one time, then I deleted all the data on it and then it stayed like this in the proxmox UI

but when I look at it from the VM in that <1min, it is actually quite empty.


@fabian Will try to get the logs soon. Life just gets in the way lately

You should enable trim/discard support for your VM's disk and run fstrim -av in it.

your screenshot shows cam-local-storage being an LVM-thin storage - you also seem to have a local mountpoint that uses the same name, but that is not the storage you see on the UI

what does "lvs" output? please also post your storage.cfg!

Ou my god...
After trimming and proxmox showing 12% used. The VM didn't crash in 1minute.
If this was it, I feel so stupid...
So far 5hours uptime...

Update: uptime 28hours, seems that was really the problem

Hey everyone,
I have a N5105 Topton mini PC and I still experience VM crashes even with updated microcode. In my case, it's the pfSense VM that goes up to 100% CPU and stops responding :


I'm on PVE 7.4-3 with kernel 5.19.17-2

cat /proc/cpuinfo | grep microcode gives me this :
microcode : 0x24000024
microcode : 0x24000024
microcode : 0x24000024
microcode : 0x24000024

This occurs every 60 days or so as you can see on my monitoring graph for uptime :


I've tried messing with CPU flags on the VM as well but it did not change anything :


Any idea what I could do ? Would upgrading the kernel to 6.2 change anything ?

I've checked the logs but I do not see any relevant info and there is no crash log in pfsense.

Thank you for your help !
