[Xen-devel] VHD suport in QEMU?

[Philipp Hahn <hahn@xxxxxxxxxxxxx>]

Hello,

sorry for high-jacking this thread, but I have a questing regarding VHD 
(without the X): Xen-4.3 switched to upstream QEMUs support for VHD. The 
dropped their own VHD implementation in blktap2, which supported backing 
chains, which QEMU currently doesn't. The Xen implementation 
(xen/tools/blktap2/vhd/lib/ is BSD 3 clause) also supports some kind of journal.
1. Does someone know if the journal support for VHD is somehow related to VHDX?
2. Has somewone put some work into supporting backing chains? I started to have 
a look myself some time ago, but had to do other work since then.

Sincerely
Philipp
