As both the error message and the commit message refer to "big real mode" I tried a locally build 3.5.3 kernel with commit "KVM: VMX: Fix KVM_SET_SREGS with big real mode segments" reverted.
With an unmodified local build 3.5.3 I could reproduce the original error.
With the local build 3.5.3 with the reverted commit the vm boots fine. It passes pxe and boots successfully from cdrom (server beta1 iso). Also the installed server boots fine with the revert.
NB: I left the module parameters at their default values, so especially emulate_invalid_guest_state=n for this test.
