UEFI trouble with OVMF under Xen - nothing boots

[Marcin Cieslak]

This is a follow up to the UEFI Windows boot problems
reported after 4.7 got imported:

https://lists.freebsd.org/pipermail/freebsd-xen/2016-June/002745.html

I am using FreeBSD 12.0-CURRENT #6 r314708: Mon Mar  6 13:09:31 UTC 2017     root at o.saper.info:/usr/obj/usr/src/sys/GENERIC  amd64 as dom0

In the 4.5 times I could install and boot Windows 2016 Technical Preview 5 without
major problems. In fact, I started using this as my default Windows
environment - it was working very well and very fast.

Since 4.7 upgrade I never got Tianocore OVMF to boot - it just stops
there listing available devices:

I can browse the FS0 and there is BootX64.efi there

(not sure if "Unsupported" message is normal, never tried this
in the days Windows was working).

The zvol contains the same Windows that used to start properly, so
I suspect the filesystems there did not get corrupt. Trying
to boot the installation ISO image ends up with a same thing.

I have tried old and new ovmf images:

https://marcincieslak.com/tmp/ovmf/ovmf.bin
can be taken from http://efi.akeo.ie/OVMF/

https://marcincieslak.com/tmp/ovmf/ovmf-new.bin
extracted from https://www.kraxel.org/repos/jenkins/edk2/edk2.git-0-20170328.b2579.g2ed235f.x86_64.rpm

tried 32bit and 64bit versions, both start with the same effect.

To reproduce it, modify xen-tools Makefile to add two flags to CONFIGURE_ARGS:

CONFIGURE_ARGS+=        --with-extra-qemuu-configure-args="${QEMU_ARGS}" \
                        --with-system-seabios=${LOCALBASE}/share/seabios/bios.bin \
                        --enable-ovmf \
                        --with-system-ovmf=${LOCALBASE}/share/ovmf/ovmf.bin

Complete Makefile I am using is at

Domain configuration file:

https://marcincieslak.com/tmp/ovmf/windows-run.cfg

builder = "hvm"
memory = 4096
vcpus = 2
name = "Windows2016"
disk = [
        '/dev/zvol/zroot/windows0,raw,hda,w',
#       '/dev/zvol/zroot/vs2013,raw,hdb,w',
#        '/root/win/install.iso,raw,hdc:cdrom,r'
]
boot = "c" # Boot to hard disk image
vnc = 2
#vnclisten = "0.0.0.0"
usbdevice = 'tablet'
on_poweroff = 'destroy'
on_reboot = 'restart'
#on_crash = 'restart'
on_crash = 'destroy'
acpi = 1
bios = 'ovmf'
vif = [ 'bridge=bridge0,mac=00:16:3e:5d:0d:48' ]
videoram=16
vga = "stdvga"

It does not matter if I use "hda" or "xvda"

The qemu driver domain running looks like this:

https://marcincieslak.com/tmp/ovmf/qemu-process

/usr/local/lib/xen/bin/qemu-system-i386 \
        -xen-domid 30 \
        -chardev socket,id=libxl-cmd,path=/var/run/xen/qmp-libxl-30,server,nowait \
        -no-shutdown \
        -mon chardev=libxl-cmd,mode=control \
        -chardev socket,id=libxenstat-cmd,path=/var/run/xen/qmp-libxenstat-30,server,nowait \
        -mon chardev=libxenstat-cmd,mode=control \
        -nodefaults -no-user-config \
        -name Windows2016 -vnc 127.0.0.1:0,to=99 \
        -display none -device VGA,vgamem_mb=16 \
        -boot order=c \
        -usb -usbdevice tablet -smp 2,maxcpus=2 \
        -device rtl8139,id=nic0,netdev=net0,mac=00:16:3e:5d:0d:48 \
        -netdev type=tap,id=net0,ifname=xnb30.0-emu,script=no,downscript=no \
        -machine xenfv -m 4080 \
        -drive file=/dev/zvol/zroot/windows0,if=ide,index=0,media=disk,format=raw,cache=writeback

Nothing special in the "xl dmesg", Xen is just starting OVMF.

I don't know even where to start to troubleshoot this...
Anyway to get to the OVMF debug output, maybe?

I've tried some other UEFI non-Windows installers and all images behave
the same: no surprise, as no Windows code had a chance to run yet.
