Hi,
Patch 1 and 2 mainly fix bug about balloon not working correctly when we do
hotplug memory. It takes 'ram_size' as VM's real RAM size which is wrong
after we hotplug memory.
This bug exists since we begin to support hotplug memory, and it is better
to fix it.
Patch 3 add some trace events, it helps debugging balloon. If it is unnecessary,
pls feel free to remove it.
Thanks,
zhanghailiang
What about other users of ram_size?
Are they all incorrect?
pc-dimm is only supported in x86 target now, and i am not quite sure if hotplug
memory will break migration. I'll look into it. Thanks.
v2:
- fix compiling break for other targets that don't support pc-dimm
zhanghailiang (3):
pc-dimm: add a function to calculate VM's current RAM size
