Memory ballooning?

[dereitz]

Does anyone know if the HA OS VM build supports memory ballooning as described at the below link?

I tried to set a minimum of 1GB and a max of 2GB, but the memory footprint always appears to be 2GB as reported in Proxmox. The actual memory utilized appears to only be about 835MB, so I'd have thought it would shrink to only 1GB.

It would be fantastic if this worked, so if anyone has attempted this and can share your experience, I would greatly appreciate it!

Thanks,
David

In my testing using Virtual Manager the system starts up with the minimum configured of 1GB, so that looks good here.

Technically, HAOS commes with VirtIO ballooning support, and the kernel module is loaded by default. So it really should work.

Does ballooning in your Proxmox setup work with other Linux distribution?

To be honest, I haven't tried other Linux distributions, but can certainly try it for validation of how "it should work".

It seems that Virtual Manager doesn't support dynamic ballooning, but changing the current assignment at any point in time seems to work and apply to the system:

Interesting! I'll have to do some further testing in Proxmox.
