Yeah, but you have to recompile qemu every time you reboot your system to make it work again. :P |

works for me, replacing
mknod /dev/kqemu c 250 0
with
mknod /dev/kqemu c 241 0
just ls -l /dev/kqemu after emerged it...
crw-rw-rw- 1 root root 241, 0 Mar 13 16:46 /dev/kqemu
see 241 not 250.

Thanks I'll try that. :)
The manual said 250 so I assumed that it would be correct :P |

... maybe i'm missing something (or just overly tired), but when i run "qemu -user-net -m 384 -hda myimage.img -cdrom /dev/cdrom1 -boot d", not much appears to be happening. my cpu jumps to 99% and it just sits there.. am i supposed to do something?  |

I'm starting to think it might be something wrong with my system.
EDIT: Yep, it was. I reinstalled my system and now it installs and runs fine with lu_zero's ebuild (I haven't tried the first one), but Win98 won't run.

|

I can't get the qemu-cvs ebuild to work. I am running it in my 32-bit chroot since running the standard ebuild in my 64bit enviroment would cause the emulator to freeze in certain circumstances. I'm not sure what it is.. but in 64bit the Windows 2000 installer throws page faults when I do things like move the window or click next after typing in the cd-key.
Here is what I did:
| Code: |
wget ftp://notz.homelinux.com/qemu-cvs.tar.gz
tar -xzf qemu-cvs.tar.gz
echo "app-emulation/qemu-cvs ~x86" >> /etc/portage/package.keywords
echo "app-emulation/qemu-cvs kqemu" >> /etc/portage/package.use
emerge qemu-cvs
|
The emerge proceed for a short time then I get this error:
| Code: | make[1]: Leaving directory `/var/tmp/portage/qemu-cvs-0.0.1/work/qemu/x86_64-softmmu'
make -C kqemu

I don't use my chroot often so it only has 2.4.28 installed; My real system has 2.6.11-gentoo-r3.
When I emerge qemu-cvs in my main 64bit enviroment it compiles fine, /dev/kqemu is created. However, the kqemu module cannot be found anywhere. Any ideas? I added kqemu to my packages.use.
Thanks! |

Okay, I'm not sure what's going on here, but I'm following the directions of the thread poster exactly (as far as I can tell), but when it get to the emerge step, I get
| Code: |
tinomen portage # emerge qemu-cvs
Calculating dependencies
emerge: there are no ebuilds to satisfy "qemu-cvs".
|
the tar extracted to /usr/local/portage... what's going on? I'm sure this must be some simple little thing I'm overlooking.
edit: okay, a dude ssh'd into my machine and helped me out. I needed to add /usr/local/portage to PORTDIR_OVERLAY in make.conf
qemu-cvs is compiling right now.

it seems that the tarball for the ebuild is no longer on the ftp server
does anyone know if it is hosted anywhere else? I checked gentoo-portage and they don't have it either.
I really would like to get this installed so I can dump VMWare. |

The permissions on /dev/kqemu get reset by udev on my machine.
| Code: | zeus gentoo-qemu # /etc/init.d/kqemu stop
* Unloading kqemu module... [ ok ]
zeus gentoo-qemu # /etc/init.d/kqemu start
* Loading kqemu module...
* Creating /dev/kqemu... [ ok ]
zeus gentoo-qemu # ls -al /dev/|grep kqemu
crw-rw-rw- 1 root root 241, 0 Apr 24 00:17 kqemu
zeus gentoo-qemu # ls -al /dev/|grep kqemu
crw-rw---- 1 root root 250, 0 Apr 24 00:17 kqemu |
Even when creating a new device with 241, it gets reset by udev to 250 and has its permissions reset to 0660 (udev uses the default mode 0660 as set in /etc/udev/udev.conf).
So an additional udev permission rule is needed. So I added /etc/udev/permissions.d/10-local.permissions with the following content:
| Code: | | kqemu:root:root:0666 |
That kept the permissions of /dev/kqemu on 0666.
Hope this helps the udev users out there.

Following the guide as presented in my blog (http://blog.bravecobra.com/index.php/linux/2005/02/25/emulating_an_os_with_qemu), I came up with the following startup script. You'll also need the following packages
| Code: | | #emerge vde iptables |
Another requirement would be to enable the tun device in your kernel (vde uses that to setup a private networking device).
| Code: | | Device drivers -> Networking support -> Network device support -> [*] Universal TUN/TAP device driver support |
When all that is enabled, you can start using the following startup script.
| Code: | #!/sbin/runscript
udev() {
# Create the KQEMU device if using udev
if [ -a /dev/kqemu ] ; then
einfo " /dev/kqemu exists"
else
ebegin " Creating /dev/kqemu"
mknod /dev/kqemu c 241 0
chmod 666 /dev/kqemu
fi
}
start() {
ebegin "Starting kqemu"
ebegin " Loading kqemu module"
/sbin/modprobe kqemu
udev
eend $?
ebegin " Starting up virtual network"
vde_switch -tap tun -daemon
ifconfig tun 192.168.254.254
chmod 666 /tmp/vde.ctl
echo "1" > /proc/sys/net/ipv4/ip_forward
iptables -t nat -A POSTROUTING -o eth0 -j MASQUERADE
eend $?
eend $?
}
stop() {
ebegin "Stopping kqeum"
ebegin " Unloading kqemu module"
/sbin/modprobe -r kqemu
eend $?
ebegin " Stopping virtual network"
killall -9 vde_switch
rm /tmp/vde.ctl
eend $?
eend $?
}
|
Of course I could start finetuning that by having the virtual TUN ip set in /etc/conf.d/kqemu etc, but you'll get the idea. Don't forget the above udev permissions rule .

Did you emerge with the softmmu flag? Otherwise it's quite normal nothing happens.
