Did you ever think about using "templates" for the XEN guests?
The problem is that we would need to cache a lot of different images on each build host and this may lead to lacking disk space.
Well, if you have images for the "simple" targets, you should be done with about 20 images and would already cover the majority of the builds.
Additionally, the setup of the systems is mostly IO bound due to the fast CPUs, so I do not see a majort advantage.
Hmmm, I can't imagine that rpm is really as fast as cp ;-)
well, rpm itself is, but it does need to uncompress the rpms with bzip2 algorithm which is the real cpu killer. However, it seems that our cpus are indeed fast enough for that, it does at least not speed up so much that the extra overhead of storing and refetching of images gets compensated to our internal tests.
but if you say so, I'll believe that your CPUs are fast enough (or the harddisks are too slow *g*)
The harddiscs are 5 SATA discs using striping for maximal performance on the newer build hosts, so they are also fast ... -- Adrian Schroeter SUSE LINUX Products GmbH, GF: Markus Rex, HRB 16746 (AG Nürnberg) email: adrian@suse.de --------------------------------------------------------------------- To unsubscribe, e-mail: opensuse-buildservice+unsubscribe@opensuse.org For additional commands, e-mail: opensuse-buildservice+help@opensuse.org
