Subject: Question on Compression for Raw Image
Date: Tue, 20 Oct 2020 01:31:13 +0000	[thread overview]
Message-ID: <516589845d6f42d0b00784d16b59b5dc@intel.com> (raw)

Hi,

Does anyone know the reason why raw-format.c doesn't have compression support (but qcow has the supported added)?
For example, raw image backup with compression, "qemu-img convert -c -O raw origin.img  dist.img", doesn't work.

Thanks,
Wei
