One thing to try, if you haven''t already-> After enabling in the bios, be sure to actually power off your machine for 10 seconds, don''t just do a soft reset or the VT setting may not be implemented.

Did you also tried it with the i386-version of SLES 10? At least at beta-stage of SLES 10 I had much better experience with the 32 bit version!> Is the VT enabled by default in XEN kernel?In the versions of SLES 10 I used it was enabled by default and it was working on Intel S3E2244, Platform Bensley S3E2200 with dualcore/dualcpu Xeon 3,2GHz (P4/netburst). Normaly if there is a BIOS entry for VT it should work, because important is the CPU, the chipset and the BIOS to get HVM working! -- Chau y hasta luego, Thorolf _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users
You may need to enable VT in BIOS.

[Xen-users] Re: [Xen-devel] A problem with Intel VT / XEN3
VT is being disabled by the BIOS, regardless of what it is telling you. That is why you get the ³VMX disabled by Feature Control MSR.² log messages that means the VT feature has been locked out by the BIOS. -- Keir On 7/11/06 14:06, "Mohamed Zohny" <mohamad.zohny@gmail.com> wrote:> knowing that VT is enabled in BIOS. > We tried to do some test to check if VT is enabled: > > # xm dmesg|grep VMX > > (XEN) VMX disabled by Feature Control MSR. > (XEN) VMX disabled by Feature Control MSR. > (XEN) VMX disabled by Feature Control MSR. > (XEN) VMX disabled by Feature Control MSR._______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users
