Subject: XP installation speed: KVM vs Xen
Date: Tue, 27 Feb 2007 14:46:45 -0600 [thread overview]
Message-ID: <1172609205.6539.9.camel@localhost.localdomain> (raw)
I've been migrating from Xen to KVM for a wide variety of reasons.
I've noticed, however, that XP installs much much faster with Xen (3.03
xen-image-xen0-2.6.17-6-generic-xen0 ubuntu) than with KVM (14).
I haven't clocked it, but for KVM it takes longer than realtime (by the
XP install clock) and with Xen it takes less than realtime.
I assume that this is all file I/O related, which raises the question:
what file system setup optimizes KVM I/O, e.g. qcow vs. raw?
