Hi List, still the question about VCPUs. When I set VCPU >= 2, then I can not boot the guest.(the guest kernel is SMP) Guest is 2.6.20-1.2952.fc6 How can I make it run with 2 VCPU :( ??? here is some other info: cpuinfo and xen configuration file. \Linux localhost.localdomain 2.6.19-1.2911.6.5.fc6xen #1 SMP Sun Mar 4 16:59:41 EST 2007 i686 i686 i386 GNU/Linux CPUinfo: processor : 0 vendor_id : GenuineIntel cpu family : 6 model : 15 model name : Intel(R) Core(TM)2 CPU T7400 @ 2.16GHz stepping : 6 cpu MHz : 2168.162 cache size : 4096 KB fdiv_bug : no hlt_bug : no f00f_bug : no coma_bug : no fpu : yes fpu_exception : yes cpuid level : 10 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 nx lm constant_tsc pni monitor ds_cpl vmx est tm2 ssse3 cx16 xtpr lahf_lm bogomips : 5422.34 processor : 1 vendor_id : GenuineIntel cpu family : 6 model : 15 model name : Intel(R) Core(TM)2 CPU T7400 @ 2.16GHz stepping : 6 cpu MHz : 2168.162 cache size : 4096 KB fdiv_bug : no hlt_bug : no f00f_bug : no coma_bug : no fpu : yes fpu_exception : yes cpuid level : 10 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 nx lm constant_tsc up pni monitor ds_cpl vmx est tm2 ssse3 cx16 xtpr lahf_lm bogomips : 5422.34 # Automatically generated xen config file name = "system2" builder = "hvm" memory = "256" disk = [ ''file:/home/songtao/Xen_Guests/Fedora6,hda,w'', ] vif = [ ''type=ioemu, mac=00:16:3e:51:be:52, bridge=xenbr0'', ] uuid = "261877a2-1d16-8684-a66b-07170a381d6b" device_model = "/usr/lib/xen/bin/qemu-dm" kernel = "/usr/lib/xen/boot/hvmloader" vnc=1 vncunused=1 apic=1 acpi=1 pae=1 vcpus=2 serial = "pty" # enable serial console on_reboot = ''restart'' on_crash = ''restart'' Songtao _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users
