The following might help tell you why you cannot delete a tun interface using ‘tunctl -d’:

lsof /dev/net/tun

This seems to be the best resource around for what I’m looking for — to easily and repeatedly launch a VM in Debian squeeze/sid 2.6.30-2-amd64 with networking and sound. virt-manager consistently provides networking without sound; the command line consistently provides sound without networking. Running this command ~# kvm -m 2048 -no-frame -net tap,script=/etc/kvm/kvm-ifup -soundhw all -hda /home/pat/vista.qcow — the error I get is:
device eth2 is already a member of a bridge; can’t enslave it to bridge br0.
/etc/kvm/kvm-ifdown: could not launch network script.

I’ll be testing-out these scripts and report back.

@Master One – Well, I mis-spoke, not VDE, but VDE functionality.

You are correct in that the term “KVM” is confusing as there are several front ends for KVM from libvirt to virsh to virt-manager to web based interfaces.

Personally I prefer to run KVM directly, from the command line, with a few scripts.

virt-manager is highly variable, IMO, in terms of functionality across distros and versions (virt-manager is not the same on Ubuntu vs Fedora for example).

bodhi.zazen, the info, that “VDE is built into virt-manager” can’t be right, because virt-manager depends on libvirt, and VDE is still not supported by libvirt.

VDE (to be precisely VDE2) is the superior way to get it all connected, and it is indeed already supported by QEMU/KVM, but unfortunately not by any of the management tools, that rely on libvirt.

There is very little up-to-date info available, and I am just trying to clue all pieces together, seems I have to go for kvm without libvirt, because I really don’t want to miss VDE (and during my tests I didn’t like it, when libvirt messed around with my iptables setup).

If anybody has some more info on that topic, or links to up-to-date tutorials, please tell.

Thanks for sharing this info.
Unfortunately the error message keeps coming. The rest seems to work very well. That’s the most important for me. Thanks for this blog.
Redirecting the error message to /dev/null and all problems seems to be solved :-)
