What are the HVM Hypercalls that are currently supported in Xen-unstable? Are the Hypercalls related to Grant tables supported? Thx, Venkat _______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com http://lists.xensource.com/xen-devel
See the hypercall entry points in xen/arch/x86/hvm/hvm.c. Most of the grant hypercalls (the ones that let you map or copy other domains'' pages) are not supported currently. -- Keir On 19/8/08 15:38, "Kumar, Venkat" <Venkat.Kumar@lsi.com> wrote:> What are the HVM Hypercalls that are currently supported in Xen-unstable? > Are the Hypercalls related to Grant tables supported? > > Thx, > Venkat > > > _______________________________________________ > Xen-devel mailing list > Xen-devel@lists.xensource.com > http://lists.xensource.com/xen-devel_______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com http://lists.xensource.com/xen-devel
Is it because of the migration issues that the grant hypercalls(mapping,copying,....)are not supported?

No, noone has done the work yet because it generally suffices to have PV guests mapping foreign memory. Noone who cares to have HVM guests able to map foreign memory has provided code to support it. -- Keir On 20/8/08 12:48, "Kumar, Venkat" <Venkat.Kumar@lsi.com> wrote:> Is it because of the migration issues that the grant > hypercalls(mapping,copying,.)are not supported? > > Thx, > Venkat > > > > From: Keir Fraser [mailto:keir.fraser@eu.citrix.com] > Sent: Tuesday, August 19, 2008 8:23 PM > To: Kumar, Venkat; xen-devel@lists.xensource.com > Subject: Re: [Xen-devel] HVM Hypercalls > > See the hypercall entry points in xen/arch/x86/hvm/hvm.c.
