Hi all, Aieee! CPU0 is toast This is the message I saw with noreboot option when I tried to install Xen on the Athlon 900Mhz PC. Is this CPU supported? dmesg output for reference: Linux version 2.4.18-3 (bhcompile@daffy.perf.redhat.com) (gcc version 2.96 20000731 (Red Hat Linux 7.3 2.96-110)) #1 Thu Apr 18 07:37:53 EDT 2002 BIOS-provided physical RAM map: BIOS-e820: 0000000000000000 - 000000000009fc00 (usable) BIOS-e820: 000000000009fc00 - 00000000000a0000 (reserved) BIOS-e820: 00000000000f0000 - 0000000000100000 (reserved) BIOS-e820: 0000000000100000 - 0000000008000000 (usable) BIOS-e820: 00000000ffff0000 - 0000000100000000 (reserved) On node 0 totalpages: 32768 zone(0): 4096 pages. zone(1): 28672 pages. zone(2): 0 pages.

>From the message, I don''t see anything that suggestsyour CPU is not supported. In the GRUB menu.lst file, you have to write down how much memory is for Domain0.

You are right! :-) The dom0_mem used to equal to my physical memory size. Now I cut it to half and it works now.

Is this CPU supported?We''ve had it working on Athlon''s, so I don''t think the CPU is the problem. Please can you post a bit more detail about what proceeds the Aieee message.

> You are right! :-) > > The dom0_mem used to equal to my physical memory size. Now I cut it to > half and it works now.I''ll make a saner error for this case. You should have got a "Error creating domain 0" error message, but it would have been obscured by further crash messages. I''ll clean that up and print a msg suggesting that the error is likely due to requesting too much memory. -- Keir ------------------------------------------------------- This SF.net email is sponsored by: SF.net Giveback Program.

Perhaps we should check that there''s actually enough memory available before starting the domain.... Using xenctl to start more domains than you have memory for doesn''t reboot the system (like it does for domain0), but the "xenctl domain new" fails and the error message is totally unhelpful. Be warned (or fix it ;-) Ian ------------------------------------------------------- This SF.net email is sponsored by: SF.net Giveback Program.
