Hi all Manage to pull together another prototype without any hack in it. The first patch adds PcdPciAllowFullEnumeration in MdeModulePkg, which short-cuts full enumeration if set to false. This one should be helpful to QEMU as well. This patch set should work with QEMU / KVM as well (read: doesn''t break). The code path is the same as before if Xen is not detected. Comments are welcomed. The tree can be found at: http:...

Actually firmware cannot find any UEFI specified booting starting points in an ISO 9660 filesystem that was created with mkisofs -b and -hard-disk-boot, but without a boot image which was marked as EFI System Partition.
