Hi

Sorry what I meant was that after bootup into the xen0 kernel I can
only see 1 cpu, I've attached my cpu list below. This server has two
spu's but only on eis being shown

cat /proc/cpuinfo
processor       : 0
vendor_id       : GenuineIntel
cpu family      : 15
model           : 2
model name      : Intel(R) Xeon(TM) CPU 3.06GHz
stepping        : 5
cpu MHz         : 3065.877
cache size      : 512 KB
fdiv_bug        : no
hlt_bug         : yes
f00f_bug        : no
coma_bug        : no
fpu             : yes
fpu_exception   : yes
cpuid level     : 2
wp              : yes
flags           : fpu tsc msr pae mce cx8 apic mtrr mca cmov pat pse36
clflush dts acpi mmx fxsr sse sse2 ss ht tm pbe cid xtpr
bogomips        : 6121.06

Any ideas?

Thanks
Shaz
