Note: Patch 1/7 is a bug fix for QCOW, that is also needed for VHDX
This adds the initial support for VHDX image files. It supports both
read and write operations, across fixed and dynamic files.
Notably, the following is not yet supported:
* Differencing files
* Log replay (so we will refuse to open any images that are not 'clean')
* .bdrv_create()
This series, and additional work to add in the above features, may be found
at:
https://github.com/codyprime/qemu-kvm-jtc/tree/jtc-vhdx-v1
git://github.com/codyprime/qemu-kvm-jtc.git, branch jtc-vhdx-v1
Jeff Cody (7):
block: only force IO completion in .bdrv_truncate if we are shrinking
qemu: add castagnoli crc32c checksum algorithm
block: vhdx header for the QEMU support of VHDX images
block: initial VHDX driver support framework - supports open and probe
block: add read-only support to VHDX image format.
block: add header update capability for VHDX images.
block: add write support for VHDX images
