Dear All,

My VM automatically shutdown/crashed every 02 days. I dont know where have to check what is the issue is.

Can someone plz assist how can i find out the issue and resolve?
 
First I would check your system log for "OOM" messages in case PVE kills your VM because of running out of RAM.

How much memory does have host? and show your vm-s configuration

Thank you for the reply.

Here is the Node memoery details:-

1711383436948.png

I am running 2 VM and the configuration below:-

VM 100:-

VM 101:-

1711383516130.png


VM 101 is the one who crashes frequently.
 
84GB RAM assigned to VMs while your host has only 64GB is a bad idea. You‘ll have to lower RAM assignment to both VMs, for example 24GB on each VM. If you use ZFS additional 10% of your RAM will be assigned for caching.

X to 50% by default.

And yes. You are massivly overprovisioning your RAM so no wonder if PVE kills your VM when running out of memory as it will usually kill the process first that consumes the most RAM.
