[Qemu-devel] [PATCH 0/4] Don't write headers if BDS is INACTIVE

Posted by Jeff Cody 8 years ago

VHDX and Parallels both blindly write headers to the image file
if the images are opened R/W.  This causes an assert if the QEMU run
state is INMIGRATE.  Rather than blindly write on open, latch the first
write to the image, and update the header then.

Jeff Cody (4):
  block/vhdx.c: Don't blindly update the header
  block/parallels: code movement
  block/parallels: Don't update header until the first actual write
  qemu-iotests: update unsupported image formats in 194
