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

[Alexandre DERUMIER]

finally,after many years, blockdev-add and blockdev-del are ready  :)

I think it could be great to implement it for proxmox 5 ! (qemu 2.9 ?)

and also blockdev-mirror.

This should allow clean discard,skip zeroes for some storage like rbd.

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.
