Hello,
I'm trying to use the memory hotplug feature, but it fails for qemu 9.0 with a virt-9.0 machine:
$ qemu-system-aarch64 -M virt-9.0 -nographic -serial null -m 1G,slots=2,maxmem=2G -object memory-backend-file,size=1G,id=mem0,mem-path=./test_ram -device pc-dimm,memdev=mem0,id=dimm0
QEMU 9.0.0 monitor - type 'help' for more information
qemu-system-aarch64: -device pc-dimm,memdev=mem0,id=dimm0: memory hotplug is not enabled: missing acpi-ged device
I searched how to use the acpi-ged device, but I didn't find anything. Also, it doesn't appear when running $ qemu-system-aarch64 -device help
Thanks,
-Cristobal
