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

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?
