Re: [Qemu-devel] where can I find the latest memory hot plugging patch for Qemu?

[Kolk, G. van der]

Oops,

RTFM! :)

PS:
  Windows guest requires SRAT table for hotplug to work so add an extra option:
   -numa node
  to QEMU command line.

So status is, windows works. linux does not.

See attachment for more info

Hi Igor,

I’m trying the memory hot plug. But I have trouble getting it to work. This is what happens. I tried some tested guest OSes and some untested.

I tried three flavours of linux with automatic or manual memory hot plug support:

CentOS 6 cpu hotplug: works memory hotplug: Kernel sees memory, but ext4 filesystem crashes, says it’s mounted readonly, but cannot execute anything to try and read the logs.

latest Ubuntu and debian: same problem

Windows 2012: cpu hotplug: works memory hotplug: windows keeps running, but does not see the memory. nothing shows up in event viewer.

Used commands to add memory:

(qemu) object_add memory-ram,id=mem1,size=1G

object_add memory-ram,id=mem1,size=1G

(qemu) device_add dimm,id=dimm1,memdev=mem1

device_add dimm,id=dimm1,memdev=mem1

Am I doing something wrong? How can I make this work? If you need any logs. Let me know which one.

Regards,

Gerrit

Dear Qemu developers,

I'm doing a masters thesis project which involves Qemu. Especially cpu and memory hot plugging. But I have a hard time  finding the right git repository which contains the latest memory hot plugging work. Can anyone please point me in the right direction?
