Unable to bring up Mini-OS on x86_64
I am getting the following error when I try to bring up Mini-OS on x86_64 Xen (unstable: 9994). It is dying in xc_linux_build() causing xend to fault and restart. Any clue why this happening? Has something changed in the builder that Mini-OS needs to be aware of? PS: I tried reverting changeset 9993 (Allow linking of mini-os with application-specific object code), but still got the same error
