Just finished building out my new Athlon 64 X2 machine and wanted to share my results: Hardware Motherboard was an Asus M2R32-MVP. I had many issues with stability until I updated the BIOS. Since then it's been stable as a rock. This board comes with an SB600 hard drive controller, VIA Firewire, Marvell Gig NIC. For the hard drive controller I first tried with the following kernel params: all-generic-ide pci=nommconf This allowed FC6_X64 to see the drives in LegacyIDE mode. I added a second hard drive and configured a RAID1 set using the Asus tools. FC6 could no longer see the drive (now part of a RAID set) until I used: pci=nomsi Then everything worked beautifully. Software No real issues. I installed the xen kernel. The virtual machine console is beautiful. The only glitch I had was trying to get a 32bit FC6 install to work as a para-virt. I ended up having to use the FC6_64 which so far has not complained. Oh, and the mouse pointer is doubled up inside the graphical console. It seems to track differently than the host. It works but is clumsy. fedora-ds didn't seem to be available.. -- * The Digital Hermit http://www.digitalhermit.com * Unix and Linux Solutions kwan@xxxxxxxxxxxxxxxxx
