Can I set the VM memory limit ?

[tingfung]

I am testing the proxmox for our virtual environment.
The esxi have a vm memory limit function but I can't found in proxmox.
Proxmox can limit the memory through qemu-monitor with balloon function.
How can I set the memory limit permantently ?

hi,
afaik,you set the desired vm ram in vm config
then if your pve host has ksm enabled, that vm ram will remain the same, from the vm pov,
but the host could save _its_ ram deduplicating ram pages used in common by other vm on the same host...
esxi servers probably use other concepts to overcommit vm ram

I am not sure if I understand your request.

Memory for KVM VM is defined on the hardware tab.

Um....if my concept is right, the vm memory set to 1024m and balloon 400mb, then is it limit to 1024-400 = 624.
There have ksm or vswap to overcommit the memory, but now i want discuss the balloon,
I think if proxmox can change the balloon memory, it is not very hard to do a memory limit function?
