Yep, its fixed, now the newly created domain crashes, probably during
kernels initial page table setup (pfn 0 looks like that), which likely
is a builder bug.
I get this now:
(XEN) DOM1: (file=mm.c, line=1528) Bad type (saw 33030001 != exp
e0000000) for mfn c72 (pfn 0)
(XEN) DOM1: (file=mm.c, line=505) Error getting mfn c72 (pfn 0) from L1
entry 00c72063 for dom1
(XEN) DOM1: (file=mm.c, line=3054) ptwr: Could not revalidate l1 page
(XEN) domain_crash called from mm.c:3055
(XEN) Domain 1 (vcpu#0) crashed on cpu#1:
(XEN) ----[ Xen-3.0-unstable Not tainted ]----
(XEN) CPU: 1
