Hi, I have a new questions about the ARM-Xen. (1) Following wiki in http://wiki.xen.org/wiki/Xen_ARMv7_with_Virtualization_Extensions, are this repos latest? Xen: http://xenbits.xen.org/hg/xen-unstable.hg Linux Dom0 and DomU: The *arm-privcmd-for-3.8* branch of git://xenbits.xen.org/people/ianc/linux.git<http://xenbits.xen.org/gitweb/?p=people/ianc/linux.git;a=shortlog;h=refs/heads/arm-privcmd-for-3.8> (2) Is the ARM PV interfaces for IO same as X86?

However we have few outstanding patches, already sent to the list by me or Ian, but still unapplied.> (2) Is the ARM PV interfaces for IO same as X86?I guess you are referring to the Linux PV frontend and backend drivers? Like netfront/netback and blkfront/blkback? If that is the case, then yes, we are using exactly the same frontend/backend driver pairs as in Xen x86. _______________________________________________ Xen-devel mailing list Xen-devel@lists.xen.org http://lists.xen.org/xen-devel
Thanks Stabellini. I saw the slides of New PVH Virtualisation mode for ARM Cortex A15 and x8<http://blog.xen.org/index.php/2012/09/21/xensummit-sessions-new-pvh-virtualisation-mode-for-arm-cortex-a15arm-servers-and-x86/>, but can''t understand why no PVOPs and no shadow pagetables bacuase of nasted paging in HW? josh zhao 2012/12/14 Stefano Stabellini <stefano.stabellini@eu.citrix.com>> On Fri, 14 Dec 2012, Josh Zhao wrote: > > Hi, I have a new questions about the ARM-Xen.

Yes, that is correct: thanks to nested paging in HW we don''t need shadow pagetables in the hypervisor or PVOPS in the Linux kernel. On Sun, 16 Dec 2012, Josh Zhao wrote:> Thanks Stabellini.
