Hi, I just installed Debian 5.0 64bit + Xen 3.4.1 from sources + 2.6.31 aka Susexenified kernel on new SuperMicro server with single Nehalem Xeon E5520. 2.6.31 kernel is working w/o problem, even onboard Intel gigabit NICs are ok with igb driver compiled in. Problems: 1) when booted to xen kernel I can''t access console over IPMI "remote control". I can see console but cannot type anything I tried console=vga, console=tty0, console=hvc, console=xvc in dom0 grub config but nothing works 2) unixbench When I run unixbench tool on pure debian kernel 2.6.26 the final score on single CPU E5520 is around 830 points When I run same tool on xen dom0 with 2.6.31 kernel than the score is aroun 370 points only I was suspecting hypethreading but disabling it in bios doesnt make big difference. Any help greatly appreciated. Br Peter Braun _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users
Hi Peter, I would check that the Baud rate in your Bios, IPMI Firmware (May be applicable if you are using Ipmiutil or IPMITool) and grub.conf all match. I have seen this sort of issue in cases where they don''t. I''m afraid I have no idea about the Unixbench prob.

Hi, check Baud rate, Bios etc.... But when running non-xen bios everythings is working correct!

Recreating dom0 kernel config from sratch - and now its working OK! Now still fighting with unixbench - why is there so huge difference between non-xen and xenified kernel? 350 vs 830 points?
