[Qemu-devel] [PATCH v2 0/3] vmdk: Add read-only support for the new seSparse format

Posted by Sam Eiderman 4 years, 10 months ago

v1:

VMware introduced a new snapshot format in VMFS6 - seSparse (Space
Efficient Sparse) which is the default format available in ESXi 6.7.
Add read-only support for the new snapshot format.

v2:

Fixed after Max's review:

* Removed strict sesparse checks
* Reduced maximal L1 table size
* Added non-write mode check in vmdk_open() on sesparse

Sam Eiderman (3):
  vmdk: Fix comment regarding max l1_size coverage
  vmdk: Reduce the max bound for L1 table size
  vmdk: Add read-only support for seSparse snapshots
