[Qemu-devel] trim in windows guest witch virtio

[Libaiqing]

Hi paolo,
    Recently I test trim function,and it works well in linux guest with ext4 fs.

    How to test it in windows guest? I got some info like this: 
      1 windows7 can send discard command when the storage device is ssd;
      2 find a tool like 'fstrim', 'TRIM' the volume manually.

    What's your opinion about this.

Thanks
Baiqing.
