Hi, i got a Acer travelmate 8371 with a Intel SU3500 CPU. I use OpenSuse 11.1. When i boot the default kernel, /proc/cpuinfo shows the vmx flag. But when i boot the Xen kernel, xm dmesg shows the lines: (XEN) CPU0: VMX disabled by BIOS. (XEN) VMX: failed to initialise. (XEN) CPU0: Intel(R) Core(TM)2 Solo CPU U3500 @ 1.40GHz stepping 0a (XEN) Total of 1 processors activated. and /proc/cpuinfo has vmx flag missing. Does xen detect the CPU wrong? I''m using: (XEN) Xen version 3.3.1_18546_16-0.1.1 (abuild@) (gcc version 4.3.2 [gcc-4_3-branch revision 141291] (SUSE Linux) ) Thu May 14 20:37:39 UTC 2009 (XEN) Latest ChangeSet: 18546 Thanks for help Flo _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users

Does xen detect the CPU wrong?As far as /proc/cpuinfo goes, I believe newer versions of Xen deliberately hide that flag to prevent apps on dom0/domU from using it (which they can''t). -- Fajar _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users
