QEMU-PPC is working unstable and absent net.

Post by goodbyespy »

Hello!
I am using FreeBSD STABLE 10.4.
When I am trying to launch MAC OS 9.2.1 sometimes OS launched, but sometimes does not.
But always I got messages:

Code: Select all

Trying to write invalid spr 0 (0x000) at 00f113c0
Trying to read invalid spr 0 (0x000) at 00f113c8
Trying to write privileged spr 955 (0x3bb) at 00f164b8

Trying to write invalid spr 959 (0x3bf) at 00f16520

Sometimes I got message:

Code: Select all

main-loop: WARNING: I/O thread spun for 1000 iterations
Also I do not get network.

I think, that I made a mistake with the command line.

Code: Select all

echo "Launcing MAC ."

-prom-env "boot-args=-v" -prom-env "vga-ndrv?=true" -boot c \
-drive file=mac90.img,format=raw,media=disk \
-drive file=/DATA01/MAC/macos_921_ppc.iso,format=raw,media=cdrom \
-device usb-mouse -device usb-kbd \
-net nic,macaddr=08:00:53:55:4E:00 \
-net tap,vlan=0,ifname=tap0,script=no,downscript=no
Help me please with advice.

Hi,

The first set of warnings is harmless. We all get the "Trying to write ... " messages.

But it seems you are running an older Qemu. Your openbios date says March 15 2017.
Can you compile Qemu yourself?

To get networking going, I suggest you first try with user networking:
So remove:

Code: Select all

-net nic,macaddr=08:00:53:55:4E:00 \
-net tap,vlan=0,ifname=tap0,script=no,downscript=no
and add:

Code: Select all

-netdev user,id=network01 -device sungem,netdev=network01 
It might be your older build does not yet support the sungem network device. If you get a message saying the device is not supported, you would need to install the realtek8139 drivers in Mac OS. You can find them in an iso here: http://www.open.ou.nl/hsp/downloads3/Ma ... rivers.zip

Then use this as command line:

Code: Select all

-netdev user,id=network01 -device rtl8139,netdev=network01 
Best,

Hello!
Thank you very much Cat_7.

I have downloaded and installed drivers for the rtl8139.
But when I am using the script:

Code: Select all

# Run MAC 99 with MAC OS 9.0
echo "Launching MAC ..."
qemu-system-ppc  -M mac99 -m 256 \
-monitor tcp::62000,server,nowait \
-prom-env "boot-args=-v" -prom-env "vga-ndrv?=true" -boot c \
-drive file=mac90.img,format=raw,media=disk \
-drive file=/DATA01/MAC/MacOSRealtekDrivers.iso,format=raw,media=cdrom \
-net nic,macaddr=08:00:4D:41:43:01,model=rtl8139 \
-net tap,vlan=0,ifname=tap0,script=no,downscript=no \
-device usb-mouse -device usb-kbd
I get the next configuration:

Code: Select all

(qemu) info network
info network
hub 0
 \ hub0port1: tap.0: index=0,type=tap,ifname=tap0,script=no,downscript=no
 \ hub0port0: rtl8139.0: index=0,type=nic,model=rtl8139,macaddr=08:00:4d:41:43:01
(qemu)
and network is working.

When I am using the script:

Code: Select all

# Run MAC 99 with MAC OS 9.0
echo "Launching MAC ..."
qemu-system-ppc -L pc-bios -M mac99 -m 256 \
-monitor tcp::62000,server,nowait \
-prom-env "boot-args=-v" -prom-env "vga-ndrv?=true" -boot c \
-drive file=mac90.img,format=raw,media=disk \
-drive file=/DATA01/MAC/MacOSRealtekDrivers.iso,format=raw,media=cdrom \
-device rtl8139,id=network01 \
-netdev tap,id=network01,ifname=tap0,script=no,downscript=no \
-device usb-mouse -device usb-kbd
I get the next configuration:

Code: Select all

(qemu) info network
info network
network01: index=0,type=tap,ifname=tap0,script=no,downscript=no
network01: index=0,type=nic,model=rtl8139,macaddr=52:54:00:12:34:56
(qemu)
and net is not working.

I do not know how make hub ports with devices tap and rtl in a new syntax.

Can anybody advise me with
How make hub ports in a new syntax?

Thanks.

Is this not enough? Does the tap device get created without scripts?

-netdev tap,id=network01,script=no,downscript=no \
-device rtl8139,netdev=network01 \

Hi!
Well, I am using tap device with another simulators, SimH for example, so I create it other script:

Code: Select all

# Script to create tap0 device for emulators.
# ------------------------------------------
echo "Creating tap0 ..."
ifconfig tap0 create
sleep 3
echo "Creating bridge0 ..."
ifconfig bridge0 create
sleep 3
echo "Configuring bridge0 ..."
ifconfig bridge0 addm em0 addm tap0
sleep 3
echo "Upping tap0 and bridge0 ..."
ifconfig bridge0 up
sleep 2
ifconfig tap0 up
# -----------------------------------------
Thanks,
Oleg

Hi,

I'm sorry but my knowledge about qemu networking doesn't reach that far.
And my fedora host doesn't behave like your host.

I'm not sure I really understand the question. But if this is about using (up)script and downscript, possibly the following could be of help:
https://emaculation.com/forum/viewtopic ... 314#p56752
http://drupal.bitfunnel.net/drupal/macosx-bridge-qemu

I'm sorry in case this answer is "off". I don't know much about networking either.

FWIW -net nic with vlan has been deprecated for a while and will be removed in the upcoming QEMU 3.0 release so instead you'll need to use -netdev hubport as indicated in the patch to remove -net nic with vlan here: https://lists.gnu.org/archive/html/qemu ... 05449.html

Hi!
I am trying to use a new syntax, but I do not know how

Code: Select all

-netdev id=network01,type=hubport,hubid=0 \
-device rtl8139,id=network01,mac=08:00:4D:41:43:01,vlan=0 \
-netdev tap,id=network02,ifname=tap0,script=no,downscript=no
in the qemu monitor

Code: Select all

QEMU 2.9.0 monitor - type 'help' for more information
(qemu) info network
info network
hub 0
 \ network01: network01: index=0,type=nic,model=rtl8139,macaddr=08:00:4d:41:43:01
network02: index=0,type=tap,ifname=tap0,script=no,downscript=no
(qemu)
How can I connect a tap device to the hubport?

Manual is a very short and without examples.

Thanks for the help.

Ah wait I think I see it - you don't need a hubport at all, there is just a simple mistake in the section above: you've accidentally used -id for rtl8139 which sets the id, whereas instead you need to bind it to the netdev e.g.

Code: Select all

# Run MAC 99 with MAC OS 9.0
echo "Launching MAC ..."
qemu-system-ppc -L pc-bios -M mac99 -m 256 \
-monitor tcp::62000,server,nowait \
-prom-env "boot-args=-v" -prom-env "vga-ndrv?=true" -boot c \
-drive file=mac90.img,format=raw,media=disk \
-drive file=/DATA01/MAC/MacOSRealtekDrivers.iso,format=raw,media=cdrom \
-device rtl8139,netdev=network01 \
-netdev tap,id=network01,ifname=tap0,script=no,downscript=no \
-device usb-mouse -device usb-kbd

Hi!

Thanks so much Mcayland!

Now, I am using a new syntax.

Code: Select all

# Run MAC 99 with MAC OS 9.0
echo "Launching MAC ..."
qemu-system-ppc -L pc-bios -M mac99 -m 256 \
-monitor tcp::62000,server,nowait \
-prom-env "boot-args=-v" -prom-env "vga-ndrv?=true" -boot c \
-drive file=mac90.img,format=raw,media=disk \
-drive file=/DATA01/MAC/MacOSRealtekDrivers.iso,format=raw,media=cdrom \
-device rtl8139,netdev=network01,mac=08:00:4D:41:43:01 \
-netdev tap,id=network01,ifname=tap0,script=no,downscript=no \
-device usb-mouse -device usb-kbd
Issue with network solved.
