Subject: [Qemu-devel] qemu-img convert cache mode for source
Date: Wed, 26 Feb 2014 11:14:04 +0100	[thread overview]
Message-ID: <530DBE6C.5030502@kamp.de> (raw)

Hi,

I was wondering if it would be a good idea to set the O_DIRECT mode for the source
files of a qemu-img convert process if the source is a host_device?

Currently the backup of a host device is polluting the page cache.

Peter
