I followed https://pve.proxmox.com/wiki/Hotplug_(qemu_disk,nic,cpu,memory)

setting udev rule for cpu and memhp_default_state=online kernel option for memory hotplug.

As soon as i enable memory hotplug in vm options, the vm does not boot anymore. Its stuck at the proxmox logo.

Once its disabled it boots again, proxmox is up to date.

Tested in a testlab and on productive hardware.

I tried using legacy/uefi boot and q35/i440fx chipset to no avail.

What am i missing ?
