Hello, I've installed XEN according to this tutorial: <http://www.howtoforge.com/paravirtualization-with-xen-on-centos-5.4-x86_64> http://www.howtoforge.com/paravirtualization-with-xen-on-centos-5.4-x86_64 on the first XEN boot, it freezes for a very long time on: allocating pci resources starting at a8000000 (gap: a0000000:5ec00000) (the centos installation works fine) I then realized that this is caused when I set the BIOS to use Virtualization. (when I disable it, XEN boots up nicely). I have: <http://ark.intel.com/Product.aspx?id=27236> http://ark.intel.com/Product.aspx?id=27236 so I can't find any reason why this is not working... I’d appreciate any help on this matter. Regards, MtK -------------- next part -------------- An HTML attachment was scrubbed...
