[Qemu-devel] Internet access from qemu

[Dave Feustel]

I've got qemu 6.1 running on OpenBSD 3.7.
I'm  running the OpenBSD 3.7 image file which
I got from free.oszoo.net.
I want to be able to access the internet from qemu.

I am now able to access the apache website on the  host 
I have set up pf+nat for the private address of 10.0.0.2 
used by qemu, but I cannot make contact  with the internet.

Here is my pf ruleset, adapted from the example on page 141
of Artymiak's _Building Firewalls..._, 2nd ed.
 How do I fix it to enable ip traffic between qemu and the internet?

Thanks,
Dave Feustel

---my pf ruleset-----

scrub fragment reassemble
scrub reassemble tcp
NoRouteIPs = "{ 127.0.0.0/8, 192.168.0.0/16, 172.16.0.0/12 }"

ExtIF = "xl0"
ext_ad = "(xl0)"
prv_ad = "10.0.0.0/24"
nat_proto = "{tcp, udp, icmp}"

nat on $ExtIF inet proto $nat_proto \
        from $prv_ad to any -> $ext_ad

block in  quick on $ExtIF from $NoRouteIPs to any
block out quick on $ExtIF from any to $NoRouteIPs

Dear Dave,
The list you are posting your messages to is a developer's list. It's
not supposed to be a toubleshooting list for anything else than real
undesired behaviour (i.e., software bugs).

If you need assistance to configure QEMU on your operating system,
please visit the QEMU Users Forum:

http://qemu.dad-answers.com/

I'm positive you'll find there experienced users willing devote much
more time to assist you then the QEMU developers are able to.

Best wishes,
André

Thanks for the friendly advice - I aim to please.  
Here's a real (but minor) bug -

When I boot the 3.7 openbsd image file from free.os.zoo.net
on my OpenBSD 3.7 system and start qemu 6.1,
everything works well *except* for the fact that the keyboard
keys are not all properly mapped. In particular, I have found
*no* keys which generate ":" or "#" in console mode. These 
missing codes make using vi hard. Also, several keys map to 
codes not indicated on the keys. the key marked "/" maps to "-" 
and  the "&" key maps to "/". Other keys map to British currency
symbol, etc which make me wonder if the qemu-simulated Openbsd
thinks I have a European keyboard (I have a U.S. keyboard).

I deal with these errors by starting up XWindows right away.
All the keycode problems seem to disappear in XWindows.

Getting qemu to run on OpenBSD was a Big Event for me. I hope to become
a qemu developer after I figure out how to get the internet access
issue resolved. I expect to write up some qemu how-to documents
almost immediately. I will be putting them up on my website unless
you have other suggestions.

Thanks again,
Dave Feustel

This was fixed in the 0.7 series with the addition of keymaps support.

I don't know what's the status of the OpenBSD port of QEMU, but I know
the one from FreeBSD works perfectly as long as you compile it from
the ports collection. You might want to use the port tarball
(http://www.freebsd.org/cgi/cvsweb.cgi/ports/emulators/qemu/qemu.tar.gz?tarball=1)
to see what was needed to compile QEMU under FreeBSD and adapt the
necessary changes to OpenBSD.

I highly recommend this, because AFAICT the 0.6 series are no longer supported.

Best wishes,
André

qemu 0.7.1 (or .2) is included in OpenBSD 3.8, but I have not got a cdrom 
copy of 3.8 yet, so I am making do with 3.7 and .6.1 for the time being. 
Physical booting from cdrom is broken in the OpenBSD port of qemu 0.6.1, 
but booting from an iso image works.

I tried building the qemu source code from the qemu site on OpenBSD, but
the make stopped because, among other issues, there is no libutils.h on my system. 
I googled a bit but did not find the file. I was informed via email that libutils.h is a 
"linux thingie". I haven't gone any further with the qemu build since. I have been 
instead concentrating on learning how to use qemu. The internet access problem is 
hopefully my last hurdle. Then I start working on some how-to's and maybe get
serious about building qemu at home.

I want to get qemu to compile on OpenBSD so I can keep up with the latest version.

Thanks,
Dave

That's your first mistake.  You're unlikely to get any particularly helpful 
answers if you're still using such an old version of qemu.  There have been 
an awful lot of bugs fixed since 0.6.1

That was not a mistake; that was (and still is) a start
until I can upgrade to OpenBSD 3.8 and its relatively
current version of qemu. I have started porting open
source software directly to my computer to get around
the 6-month upgrade cycle of OpenBSD. Some projects
KDE especially, are just too big for me to tackle. But
Qemu and QT are well within my capabilities. I expect
to get real busy with qemu since I have a long, long, *long*
held interest in simulators. Qemu is going to be a big
part of my life since it will make easy trying out on OpenBSD
all those Linux distros that come with each issue of Linux Format, etc.
I may even come up with some interesting enhancements
to qemu. We'll see in time.

Glad to hear it! I really want to upgrade, I just can't right now.
