Hi. I have a new server and learning Xen. The server runs Centos 5.5 Xen 3.0.3. The machine is a Supermicro 6026T-TF with the MoBo X8DTE/X8DT6 with the Intel E5620 which Intel say that support Virtualization. I have enable this feature in my BIOS and other settings about Technology and I still cannot see the flag: -Intel Virtualization Tech Enable. -Intel VT-d Enable. I don''t see the flag vmx went I run cat /proc/cpuinfo If Centos doesn''t show this flag it means that Xen cannot run Full-Virtuliation Guest OS? Thanks all for your time. _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users
I''ve seen the flag not showing before aswell. Not sure why - But it still works with HVM.

Xen *hypervisor* (xen.gz) uses VMX, so dom0 doesn''t see it. See "xm info" and check the caps, you should see hvm listed there. Also read "xm dmesg" to see the Xen hypervisor boot messages.. there you should VMX/HVM getting enabled in the hypervisor. -- Pasi _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users

Now, lets get the info u say running xm dmesg: xm dmesg | grep VMX (XEN) VMX: VPID is available. (XEN) HVM: VMX enabled (XEN) VMX: MSR intercept bitmap enabled (XEN) VMX: VPID is available. (XEN) VMX: VPID is available. (XEN) VMX: VPID is available. (XEN) VMX: VPID is available. (XEN) VMX: VPID is available. (XEN) VMX: VPID is available. (XEN) VMX: VPID is available. xm dmesg | grep HVM (XEN) HVM: VMX enabled (XEN) HVM: Hardware Assisted Paging detected and enabled. This mean that I have my server ready for HVM?
