Subject: [Qemu-devel] [PATCH v2 0/19] write/create for Parallels images with reasonable performance
Date: Tue, 30 Dec 2014 12:28:12 +0300 [thread overview]
Message-ID: <1419931701-19362-1-git-send-email-den@openvz.org> (raw)
This patchset provides an ability to create of/write to Parallels
images and some testing of the new code. Writes are not optimized
now at all, we just modify catalog_bitmap and write those changes
to the image itself at once. This will be improved in next steps.
This patchset consists of not problematic part of the previous
patchset aka
[PATCH v4 0/16] parallels format support improvements
and new write/create code but it does not contradict questionable code
with XML handling there.
Kevin, I would appreciate if you will quick look into proof-of-concept
patch aka
[RFC PATCH 1/1] block/parallels: new concept for DiskDescriptor.xml
to validate that approach for DiskDescriptor.xml problem.
Changes from v1:
- patches 13-19 added, which boosts performance from 800 KiB/sec to
near native performance

P.S. Should I add myself to MAINTAINERS of this driver?
