vm windows server found stopped

[MB_Gian]

hi, i am new to proxmox setup and i am having random problems with a new server.
this server has proxmox ve 8.3.0 and a windows server 2022 vm. i find the vm turned off after a few days of operation. host works fine. then i start the vm. i read some similar posts but i dont know what i can do? thanks

Check if stopped by oom killer, command to run from Proxmox \ Shell :
journalctl -t kernel -g oom

assign less memory to VM
Don't over allocate memory.

You may increase the tolerance of the lack of free ram by a few percent by utilizing zram.

so i need to give more ram to host?

what should I do? do you have any examples?

~# apt show zram-tools

Description: utilities for working with zram
 zram is a Linux kernel module that allows you to set up compressed
 filesystems in RAM.
 .
 zram-tools uses this module to set up compressed swap space.
 This is useful on systems with low memory or servers
 running a large amount of services with data that's easily swappable
 but that you may wish to swap back fast without sacrificing disk
 bandwidth.

Just install it: apt install zram-tools

Look into the manual: man zramswap

Customize it to fit your needs: vi /etc/default/zramswap

Verify that it works as expected:

~# zramctl
NAME       ALGORITHM DISKSIZE  DATA  COMPR  TOTAL STREAMS MOUNTPOINT
/dev/zram0 lz4             8G  1.5G 584.7M 620.6M      16 [SWAP]

Easy

PS:I had skipped starting the service...
