Hi Everyone, I upgraded my CentOS 5.5 to Xen 3.4.2 using this guide: http://www.syntaxtechnology.com/2010/01/upgrade-xen-3-0-on-centos-5-4-x86_64-to-xen-3-4-2/ Now, using the new kernel that it gave me, the system doesn''t seem to be able to detect vt-x.. In virt-manager, Local Install Media and Network Boot are greyed out.. Any ideas? Thanks _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users

It worked fine with the orignal version of Xen that came with CentOS 5.5. It''s a brand new server opened today from Dell which support Vt-x and Vt-d. Virtualisation technology is enabled in the BIOS _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users

I suppose you had the VT extension enabled before the migration but suppose you fiddled with it, power down your host (like shutdown and pull the plug) and power it up again. I experienced this being necessary once because simple rebooting after getting out of the BIOS did NOT enable VT for real.

I installed Ubuntu 10.04 onto my server. I then spent a couple of hours compiling and installing Xen 4.0. Now yet again, vmx has disappeared from /proc/cpuinfo!!!! Xend isn''t working correctly, but that''s another issue, so I can''t really test any HVM guests.
