Xen appears to kernel panic. Boot up terminates and hangs with the message "agpgart: Maximum main memory to use for agp memory: 152 M. " This is a compiled Xen-2.0 latest snapshot with agp support in the kernel. Has anyone else had similar problems with agp?

Re: [Xen-devel] xen dies on Linux agpgart interace
Agpgart isn''t (yet) supported, so it''s best to avoid it for now. This will probably be fixed in a later release. You should be able to get X to work with a non-agpgart-specific (albeit slower) configuration. For reference, there''s the beginnings of a fix in the patches directory but it''s not finished yet (it''ll get you further into a boot but it''ll still crash ;-) ).

Is this AGPGART problem only in unprivileged domains, or in both privileged and unprivileged? Cheers Jerome Mark A.

Privileged guests *ought* to be able to run X with AGPGART but currently there are bugs which cause it to fail.
