[PVE-User] Hardcoded startup RAM for QEMU memory hotplug

[DERUMIER, Alexandre]

hi currently no, but it's related to the number of cpu sockets of the
vm. (it's 512mb by socket if I remember correctly).

so, you can try a vm with 4 sockets.


you can also add "memhp_default_state=online" to kernel boot option, it
should auto enable the hotplug memory dimm when kernel boot
