Hi folks, I''m having some extremely irritating performance problems trying to get a Xen system up and running. I''m following the SUSE Linux Xen live migration demo HOWTO from http://developer.novell.com/wiki/index.php/Image:XEN_migration_demo_1.1.pdf I''m using SUSE 10.0 x64-64 with xen-3.0_8259-0.1 (obtained from YOU, but also seems to be the latest available on forge.novell.com), and whenever i boot the Xen kernel, the system slows to a fraction of its native performance. My hardware is: - Dell PE SC1425, 2 x Xeon 2.8, 2 x 2 GB DDR2 RAM, 2 x 250 GB SATA - Dell PE 850, Pentium D 830 (3.0 GHz), 4 x 1 GB DDR2 RAM, 2 x 250 GB SATA My intent is to use these two machines as dom0 platforms for live migration of 5 domUs, and host the domU file systems on iSCSI over 1000baseT, served from a dedicated NetWare 6.5 SP5 iSCSI target. I haven''t even made it to booting a domU yet, as the performance of the system is so poor. My first "yast2 dirinstall" is running now, and i hope to get the domU up & running sometime today. The Xeon system supports hyperthreading, and i''ve tried with and without this, but it makes little difference - if anything without HT is slightly slower. When i''m doing ordinary work (e.g. setting up file systems, running YAST), the problem manifests as a CPU load usually somewhere over 2.5, but utilisation somewhere below 25%. Could anyone suggest why i''m seeing this behaviour?
