Re: [Qemu-devel] [PATCH for-2.9] block: Declare blockdev-add and blockdev-del supported

[Alexandre DERUMIER <aderumier@odiso.com>]

Pretty awesome news ! Congrat !

So, can we update the wiki changelog ?

http://wiki.qemu-project.org/ChangeLog/2.9

"QMP command blockdev-add is still a work in progress. It doesn't support all block drivers, it lacks a matching blockdev-del, and more. It might change incompatibly."

Objet: [Qemu-devel] [PATCH for-2.9] block: Declare blockdev-add and blockdev-del supported

It's been a long journey, but here we are. 

x-blockdev-remove-medium, x-blockdev-insert-medium and 
x-blockdev-change need a bit more work, so leave them alone for now.
