[Qemu-devel] Q35 OS install status

[Qemu-devel] Q35 OS install status

[Jason Baron]

Hi,

Linux
-----
Fedora 17: installs and ran memory tests (requires ahci cdrom fixes I 
	   posted to install)
Fedora 16: installs and ran memory tests

Windows
-------
Windows 7: Wouldn't install due to this error:
        'A required cd/dvd device driver is missing. If you have a
	driver floppy disk, CD, DVD, or USB flash drive, please insert it now.'

	That said, I did a successfull install on q35 by using the piix4-ide
	controller for the cdrom and ide drive (passed on command line).
	Also, I can get windows 7 now to recognize the ahci drives after boot by
	going into the device manager and doing a rescan for new h/w. So
	this appears to be a problem in the boot path...

Windows xp:

	Same as windows 7, wouldn't install with ahci but will install using the
	piix4-ide controller passed on command line. Not even sure if
	windows xp has ahci support.

BSD
---
Luiz tested these for me.

OpenBSD 5.1, FreeBSD 9.0 and NetBSD all worked with the ide controller
passed on the command line. AHCI didn't work.


Recently, I have been working on trying to get ahci working on Windows 7,
but if we are willing to go with the piix4-ide controller as the default for now
until we shake out ahci issues that might allow us to make faster
progress. I still need to clean up the trees a bit and re-base on top of
the QOM pcihost patches, but it shouldn't be too bad.

Thanks,

-Jason

Good job Jason, nice to know you are making progress!
Hope to see express patches soon, they have been long
in coming.

Sorry if I wasn't clear in my report, I've only tried ahci with OpenBSD.
Will try it with the others shortly. But yeah, ide controller worked with
all of them.

Btw, I didn't try any fancy settings, only plain default install.

I do remember that with PIIX, one of the BSDs failed, while all the others worked just fine. I don't remember which one. Could have been OpenBSD. Skimming through the source, it looked as if it was searching for an IDE controller and only then activated AHCI on it - which totally contradicts the usual workflow of AHCI on ICH.

I was able to run a more complete set of tests today. I've tested all three
bsds on q35 and with ide and ahci on master (1.2.0-rc0).

Summary: FreeBSD 9.0 installed on the three cases. OpenBSD 5.1 and NetBSD 5.1,
installed with ide on master, but failed on q35 and with ahci on master.

Details
=======

On all tests the default installation was performed, always selecting
a minimum set of packages. Once installation was complete, I rebooted the OS
and checked dmesg.

master with ide
===============

Command-line example:

# ./qemu -hda disks/openbsd-test.img -enable-kvm -m 1G -monitor stdio \
         -cdrom /home/lcapitulino/isos/bsd/openbsd-amd64-install51.iso -boot d

Results:

 o FreeBSD 9.0: OK

 o OpenBSD 5.1: OK

 o NetBSD 5.1: OK

master with ahci
================

Command-line example:

# ./qemu -device ahci,id=ahci0 \
         -drive file=disks/freebsd-test.img,if=none,format=raw,id=drive-sata0-0-0 \
         -device ide-drive,bus=ahci0.0,drive=drive-sata0-0-0,id=sata0-0-0 \
         -enable-kvm -m 1G -monitor stdio \
         -cdrom /home/lcapitulino/isos/bsd/FreeBSD-9.0-RELEASE-amd64-disc1.iso -boot d

Results:

 o FreeBSD 9.0: OK

 o OpenBSD 5.1: FAILED

   Fails while partitioning the disk with the following error:

      fdisk: sd0: Device not configured

   And then the installation program keeps asking you to partition the disk
   again.

 o NetBSD 5.1: FAILED

   Fails during boot. A little bit after printing:

     ahcisata0 port 0: device present, speed: 1.5Gb/s
     ahcisata0 port 1: device present, speed: 1.5Gb/s

   The kernel "oopses":

     fatal integer divide fault in supervisor mode

q35
===

Command-line example:

# ./qemu -hda disks/netbsd-q35.img -enable-kvm -m 1G -monitor stdio \
         -M pc_q35 -bios /home/lcapitulino/work/src/q35-seabios/out/bios.bin \
         -acpitable file=/home/lcapitulino/work/src/q35-seabios/out/q35-acpi-dsdt.aml
         -cdrom /home/lcapitulino/isos/bsd/netbsd-amd64cd-5.1.iso -boot d

Results:

 o FreeBSD 9.0: OK

 o OpenBSD 5.1: FAILED (same error as with ahci on master)

 o NetBSD 5.1: FAILED (same error as with ahci on master)
