[OE-core] [PATCHv4 1/5] image: Convert vmdk/vdi/qcow2 to strict CONVERSION_CMD types

Tom Rini trini at konsulko.com
Sat Jul 29 00:14:32 UTC 2017


The vmdk/vdi/qcow2 IMAGE_FSTYPEs predate wic.  As such, they provide
some similar underlying functionality in order to produce a "disk" image
that in turn can be converted into different formats that various
hypervisor types work with.  They do not however provide the ability for
other disk image types to be converted into these same output types.
Furthermore, they are less flexible than what wic does provide.  This
drops the old style vmdk/vdi/qcow2 types and re-introduces them under
the CONVERSION_CMD framework.  The equivalent of vmdk is now wic.vmdk
and so forth for the other types.

---
Changes in v4:
- Rebase to master
- Rework runqemu changes to follow the multi-line convention that was
  just introduced here

Changes in v3:
- Update runqemu to handle 'wic.vmdk' / etc correctly, as spotted by
  oe-selftest -r runqemu
- Update the runqemu tests to build wic.vmdk/etc now

Changes in v2:
- Update runqemu help (code matches .wic.vmdk as vmdk, does right thing,
  tested).
- Supply an update to yocto-docs separately, to be merged once these
  changes are live.
