----------------------------------------------------------------------------------------------BIOS"Intel Virtualization Technology"VT-x or VT-d. If there are any issues, have another look at the BIOS settings. My board (Asus Sabertooth X79) has a VT-x or "Intel Virtualization Technology" option, as well as a VT-d option. However, the VT-d section is under a different menu, you probably have to search for that. Normally VT-d would be disabled on most boards.Intel's VT-d extensions are for IOMMU or directed I/O. An extension of the standard VT-x extensions, this allows a guest operating system to have direct access to the memory and other resources of many different types of devicesUnder Xen, in order to check if VT-d works, just pass through a USB controller (use the pciback script in the Xen how-to) and check withThis means you likely have an Intel CPU with Trusted Execution Technology. Enabling this feature in your BIOS can have a negative impact on the availability of VT-d, which is a prerequisite of running HVM guests. Please disable TXT in the BIOS and you will be able to boot your HVM guests.xl pci-list-assignable-devices----------------------------------------------------------------------------------------------Start with the Xen hypervisor and the basic toolset first:[root@localhost ~]# dnf install libxc[root@localhost ~]# dnf install xen xen-hypervisor xen-libs xen-runtime//[root@localhost ~]# dnf remove xen xen-hypervisor xen-libs xen-runtime//systemctl enable xend.service//systemctl enable xendomains.service[root@localhost ~]# systemctl enable xen-qemu-dom0-disk-backend.serviceGet GRUB2 in order:// grep -E --color "multiboot|module" /boot/grub2/i386-pc/command.lst[root@localhost ~]# grep ^menuentry /boot/grub2/grub.cfg | cut -d "'" -f2Fedora (4.6.4-301.fc24.x86_64) 24 (Workstation Edition)Fedora (4.5.5-300.fc24.x86_64) 24 (Workstation Edition)Fedora (0-rescue-5a7811782f504e58b061fcc2863b9246) 24 (Workstation Edition)Fedora, with Xen hypervisor[root@localhost ~]# grub2-set-default 'Fedora (4.6.4-301.fc24.x86_64) 24 (Workstation Edition)'[root@localhost ~]# grub2-editenv listsaved_entry=Fedora, with Xen hypervisor[root@localhost ~]# grub2-mkconfig -o /boot/grub2/grub.cfgNow reboot.
