I have apache installed on localhost for testing/development purposes and want access localhost on host machine from quest qemu. But I don’t want qemu to access network. Just a localhost on the host machine.

Can you please explain how to do this?

This post was written with qemu 0.7.x. As Joel said above, with a recent version (0.8.x in this case), you have to launch qemu with the following command:

qemu /home/kevin/qemu-mdk10.1.img -net nic -net tap

You can also add -m 512 parameter if you need qemu to emulate 512 Mb of RAM.

Hi daniele,

I’m sorry, I never tried to launch several guests. I don’t know how my script will behave.

If you manage to make a more generic script to support many guests, feel free to comments about your experimentations !

That works good but how can I add another guest? I want to create a small virtual LAN.

Wow, I’ve been trying to get QEMU to recognize my network for a couple days, and your script, though very old, finally worked. I had to put in different options, my QEMU looks like this:

qemu -cdrom /dev/cdrom -hda craw.img -m 512 -usb -net nic,vlan=0 -net user,script=/etc/qemu-ifup

THANK YOU! I’ll definitely be linking to this post when I blog about my success.
