Subject: JFYI: ext4 bug triggerable by kvm
Date: Mon, 16 Aug 2010 18:00:35 +0400 [thread overview]
Message-ID: <4C694483.5010903@msgid.tls.msk.ru> (raw)
https://bugzilla.kernel.org/show_bug.cgi?id=16165
When a (raw) guest image is placed on an ext4 filesystem,
it is possible to get data corruption, now due to ext4
bug, not kvm bug.
Also, ext4 is _very_ slow on O_SYNC writes (which is
used in kvm with default cache).
JFYI.
