I have another server (not a xen kernel) which show 4 "cpu core". see below: processor : 0 vendor_id : GenuineIntel cpu family : 6 model : 23 model name : Intel(R) Xeon(R) CPU E5420 @ 2.50GHz stepping : 6 cpu MHz : 2500.086 cache size : 6144 KB physical id : 0 siblings : 4 core id : 0 cpu cores : 4 <--- LOOK HERE apicid : 0 initial apicid : 0 fpu : yes fpu_exception : yes cpuid level : 10 wp : yes flags : fpu vme de pse tsc msr pae mce cx8 apic sep mtrr pge mca cmov pat pse36 clflush dts acpi mmx fxsr sse sse2 s s ht tm pbe syscall nx lm constant_tsc arch_perfmon pebs bts rep_good pni monitor ds_cpl vmx est tm2 ssse3 cx16 xtpr dca sse4_ 1 lahf_lm bogomips : 5003.91 clflush size : 64 cache_alignment : 64 address sizes : 38 bits physical, 48 bits virtual power management: But this server runs a NON xen kernel. Both CPU's are quadcore. That's why I'm curious :) Why with a normal kernel sees 4 cores and witn a xen kernel only one? Same OS, almost same CPU (E5410-XEN_dom0 and E5420-NOT_XEN_SERVER)?? regards, Israel. > > Steve Timm > > > On Fri, 18 Dec 2009, Israel Garcia wrote: > >> Hi, >> Do you know why xen kernel shows me only one "cpu cores" when there are 4? >> >> see part of cat /proc/cpuinfo >> >> processor : 0 >> vendor_id : GenuineIntel >> cpu family : 6 >> model : 23 >> model name : Intel(R) Xeon(R) CPU E5410 @ 2.33GHz >> stepping : 10 >> cpu MHz : 2333.430 >> cache size : 6144 KB >> physical id : 0 >> siblings : 1 >> core id : 0 >> cpu cores : 1 <---only ONE >> apicid : 0 >> initial apicid : 0 >> fpu : yes >> fpu_exception : yes >> cpuid level : 13 >> wp : yes >> flags : fpu de tsc msr pae cx8 apic sep mtrr cmov pat >> clflush acpi mmx fxsr sse sse2 ss ht syscall nx lm constant_ts >> c rep_good pni ssse3 cx16 sse4_1 lahf_lm >> bogomips : 4674.06 >> clflush size : 64 >> cache_alignment : 64 >> address sizes : 38 bits physical, 48 bits virtual >> power management: >> >> I'm running XEN on debian lenny: >> grub-info: >> title Xen 3.2-1-amd64 / Debian GNU/Linux, kernel >> 2.6.26-1-xen-amd64 >> root (hd0,0) >> kernel /xen-3.2-1-amd64.gz >> module /vmlinuz-2.6.26-1-xen-amd64 root=/dev/mapper/vg0-root >> ro console=tty0 >> module /initrd.img-2.6.26-1-xen-amd64 >> >> uname -r: >> 2.6.26-1-xen-amd64 >> >> regards, >> Israel. >> >> _______________________________________________ >> Xen-users mailing list >> Xen-users@xxxxxxxxxxxxxxxxxxx >> http://lists.xensource.com/xen-users >> > > -- > ------------------------------------------------------------------ > Steven C.
