So I see a few options one or more of which we should consider:
1) Make the *static* memory size configurable:
It doesn't make sense to me to eg. want to go from 1G to 200G in
small steps. Worse is the fact that even when starting with a higher
amount knowing that I'm only going to increase it,
m size
could be great too.

Oh, are all 5 patches missing from current kernel? Or do we only need to
increase
the value?

What value should we set exactly?
Any drawbacks?

Hi,
a proxmox user has reported problem to hotplug memory with high values (48G)
https://forum.proxmox.com/threads/apt-get-upgrade-to-update-proxmox-server.30992/
Seem that qemu check about a vhost value
