Hello I''am using xen 4.1.1. I''ve created 4 domU successfully, but EPT Table is not enable, and I can''t enable it. I''ve try different option in grub (iommu=eptable, ....). According to "xm dmesg", my PC is compatible with EPT (XEN) VMX: Supported advanced features: (XEN) - APIC MMIO access virtualisation (XEN) - APIC TPR shadow (XEN) - Extended Page Tables (EPT) (XEN) - Virtual-Processor Identifiers (VPID) (XEN) - Virtual NMI (XEN) - MSR direct-access bitmap (XEN) - Unrestricted Guest (XEN) EPT supports 2MB super page. I Have attached "xm dmesg". EPT could solve my problem. thank you for your help in advance _______________________________________________ Xen-users mailing list Xen-users@lists.xen.org http://lists.xen.org/xen-users
