I updated my PVE to version 9, but now on some VMs where FreePBX runs I have Full RAM problems, the VMs have 4G of total RAM, and before on version 8 it didn't exceed 50%, now the same VMs on version 9 are at 100% RAM, why does this happen?
RAM problems with version 9
- Thread starter toto-ets
- Start date
Are you actually having problems (and the FreePBX or your Proxmox host is running out of memory) or maybe is it just a change in how memory is reported: https://pve.proxmox.com/wiki/Upgrade_from_8_to_9#VM_Memory_Consumption_Shown_is_Higher
I enabled Ballooning but I still have the same problem, Memory 100% with version 8 this did not happen
Did you check the memory usage inside the VM? That the memory graphs may not reflect the actual usage inside the VM is nothing new and not really a problem:
https://forum.proxmox.com/threads/f...ram-usage-of-the-vms-in-the-dashboard.165943/
https://forum.proxmox.com/threads/f...ram-usage-of-the-vms-in-the-dashboard.165943/
the system actually tells me that it is consuming 50%, but proxmox tells me that the consumption is at 100%, with version 8 this did not happen
So there is no urgent actual problem, just the reporting from PVE 9 is twice as high as PVE 8. (You cannot over-commit memory on Proxmox anyway.)
What Linux is your FreePBS running on? Is QEMU Guest Agent running inside the VM? Please check that the balloon driver is enabled in the Linux kernel inside the VM: https://forum.proxmox.com/threads/linux-guests-virtio_balloon-driver.139969/post-625629

I'm talking about VM with FreePBX, Asterisk VOIP switchboard, and it runs on UBUNTU 22.04.5 LTS, yes the QEMU Guest Agent is active
What is the output of
free -h inside the VM? I'm guessing the Linux in your VM is using the rest of the memory for buff/cache. (Maybe check if the ballooning driver is enabled inside the VM?)Mem: 1,9Gi 478Mi 129Mi 7,0Mi 1,3Gi 1,3Gi
Swap: 3,3Gi 303Mi 3,1Gi
How do I check if the ballooning driver is enabled inside the VM?

Please use CODE-tag. What is the VM configuration (
qm config VM_ID_NUMBER)?when i run this command in ubuntu: cat /boot/config-<XYZ>| grep BALLOON to check if it is active, it tells me file or directory does not exist
First find the config file:
Code:
ls /boot/config*
Code:
CONFIG_MEMORY_BALLOON=y
Code:
xxx
Code:
cat /boot/config-xxx grep BALLOON[CODE]
