Hi,
I have Xen 3.3.1 running with 2.6.18 kernel and Fedora . In dom0 when I run
cat /proc/interrupts I got the following output:

Which doesn''t show APIC running in my server. I checked the xm dmesg |
grep
apic and I got the following output regarding APIC
(XEN) IOAPIC[0]: apic_id 1, version 32, address 0xfec00000, GSI 0-23
(XEN) IOAPIC[1]: apic_id 3, version 32, address 0xfec8a000, GSI 24-47
Which shows that my XEN has detected APIC but in the /proc/interrupts it was
not detected. Is there any way to enable APIC in my server or to check if it
is really running???
I would appreciate any tips or advice.
Thanks ,
Ahmed
