Perhaps I am missing some of the .config options you have set that make it not work? The irqbalance daemon looks to be running - but I think you are hitting this during bootup? How long do you have to wait for this to trigger? How many CPUs did you assign to your guest? What are the "other bugs" you speak off? > guest. I'm using a RHEL5 Xen HV fwiw ... OK, so your control domain is RHEL5. Mine is the Jeremy's xen/next one (2.6.32). Let me try to compile RHEL5 under FC11 - any tricks necessary to do that?
