The following patches implement nested VMX support. The patches enable a guest to use the VMX APIs in order to run its own nested guest (i.e., enable running other hypervisors which use VMX under KVM). The current patches support running Linux under a nested KVM using shadow page table (with bypass_guest_pf disabled). SMP support was fixed. Reworking EPT support to mesh cleanly with the current shadow paging design per Avi's comments is a work-in-progress. The current patches only support a single nested hypervisor, which can only run a single guest (multiple guests are work in progress). Only 64-bit nested hypervisors are supported. Additional patches for running Windows under nested KVM, and Linux under nested VMware server(!), are currently running in the lab. We are in the process of forward-porting those patches to -tip. This patches were written by: Orit Wasserman, oritw@xxxxxxxxxx Ben-Ami Yassor, benami@xxxxxxxxxx Abel Gordon, abelg@xxxxxxxxxx Muli Ben-Yehuda, muli@xxxxxxxxxx With contributions by: Anthony Liguori, aliguori@xxxxxxxxxx Mike Day, mmday@xxxxxxxxxx This work was inspired by the nested SVM support by Alexander Graf and Joerg Roedel. Changes since v1: SMP support. Split into 6 smaller patches. Use nested_vmx structure for nested parameters. Use Array for shadow VMCS offsets. -- To unsubscribe from this list: send the line "unsubscribe kvm" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
