yes, sure, resend your patch. I would like to compare :)

(I think I'm doing it early than, before going into the main loop).

Did you see my patches posted earlier this year? I already did the same. 


I can post also an up2date version. There are some corner cases. Like mem with 
virtio.

Hi, 

This is a first try for filtering options change of running vms. 

Only hotplugable values (disk,nic,cpu), dynamics values (disk throttle, cdrom 
media change,balloon,..), 
and some options (name,onboot,...) 
are allowed. 

The main idea is to always have a config which is the same than running qemu 
guest. 

This help to avoid hanging live migration, if config have changed but qemu 
process not yet restarted. 
This also avoid confusion for users (need to stop/start after config change) 
and also helping with hotplugging to be sure that we have a config equal to 
current qemu disk/controllers. 

I'm also thinking to improve pve-manager to grey-out non modifiable values when 
vm is running. 

review and comments are welcome !
