[Qemu-devel] Qemu bug when building for OpenBSD

[Dave Feustel]

When I try to build qemu 7.2 for OpenBSD, I get a file
not found error for libutil.h in vl.c. This should not 
happen since there is no libutil.h in OpenBSD. Has
this been fixed yet? (or can someone point me to
a copy of libutil.h and its library source)?

Are these the files that libutil.h references?
/home/daf/Qemu/qemu-0.7.2}ls -l /usr/lib/libutil*
-r--r--r--  1 root  bin  40832 Aug 19 17:34 /usr/lib/libutil.a
-r--r--r--  1 root  bin  61231 Aug 19 17:34 /usr/lib/libutil.so.11.0
-r--r--r--  1 root  bin  43224 Aug 19 17:34 /usr/lib/libutil_p.a
-r--r--r--  1 root  bin  45680 Aug 19 17:34 /usr/lib/libutil_pic.a

Thanks,
Dave Feustel

Have you tried not including it? Or including util.h instead?
google suggests it's usually used for openpty(), but that bit of code is 
disabled on bsd anyway.

I tried commenting out the #include line and got by that problem.
I got another error relating to undefined symbol INT16_MAX. 
Then I put all the qemu source into an svn repository to begin editing 
it, but, upon checkout ran into a problem with links due to altered
source tree structure, about which I just posted.

This is unrelated. INT16_MAX should be provided by inttypes.h.

[Qemu-devel] why run qemu not use sudo, the /etc/qemu-ifup will not run

[swz]

I put the next three line into /etc/qemu-ifup.
#!/bin/sh
echo $* >> /tmp/qemu-ifup.$$
sudo /sbin/ifconfig ${1##/*/} 0.0.0.0 promisc up
sudo /usr/sbin/brctl addif bridge ${1##/*/}

I think when the qemu run, it will make a file in /tmp,
but actually, when I use root the run qemu, it work ok, when I user a
user, the script isn't run. Why?

Is the same with the option "-n script", when I use root to run qemu,
the script I assign will run, but in a normal user, it won't work.

Thank you!

as you did not mention /etc/sudoers i suspect you did not configure
your sudoers(5) file. read the manpage for full information. /etc/sudoers
defines which users can user predefined command/argument strings.
btw: for syntax checking after editing this file you should use visudo(8)
to edit this file.

I have configure my /etc/sudoers, like that:

Cmnd_Alias QEMU=/sbin/ifconfig,/usr/sbin/brctl
admin   ALL=(ALL) ALL
admin   ALL=NOPASSWD:QEMU


So if someone run qemu, it will use sodu to run ifconfig and brctl.

my question is: when I configure no mattler like above or as bellow: 

#!/bin/sh
echo $* >> /tmp/qemu-ifup.$$
/sbin/ifconfig ${1##/*/} 0.0.0.0 promisc up
/usr/sbin/brctl addif bridge ${1##/*/}

the script will run when use root. But when not use root or sudo, the
script won't run. I don't know why. ( the script: 
"echo $* >> /tmp/qemu-ifup.$$"  can tell me whether the script was run)
