Hi folks,
I would like to avoid running the virtual hosts with UID=0.
But if I try to create a new virtual machine without being
root, then it fails with
% name=Lenny_amd64
% kvmdir=/local/kvm
% mkdir -p $kvmdir/$name
% qemu-img create -f qcow2 $kvmdir/$name/hda.qcow2 32G
Formatting '/local/kvm/Lenny_amd64/hda.qcow2', fmt=qcow2, size=33554432 kB
% virt-install --connect=qemu:///session -n $name -r 1024 -vcpus=1 -f $kvmdir/$name/hda.qcow2 --network=bridge:br0 --vnc --accelerate -v -c /usr/local/source/hdunkel/debian-502-i386-netinst.iso --os-type=linux --os-variant=debianLenny
14:18:35.586: warning : Cannot set group when not running as root
14:18:35.757: error : Domain not found: no domain with matching name 'Lenny_amd64'
libvir: QEMU error : Domain not found: no domain with matching name 'Lenny_amd64'
The log file shows
[Wed, 05 Aug 2009 14:18:35 virt-install 14229] ERROR (virt-install:786) internal error Failed to add tap interface 'vnet%d' to bridge 'br0' : Operation not permitted

libvirtError: internal error Failed to add tap interface 'vnet%d' to bridge 'br0' : Operation not permitted
Of course an unprivileged user is not allowed to mess around
with the network interfaces, but since it says "internal error"
I wonder how this is supposed to work? Is there something
misconfigured?
Any helpful comments would be highly appreciated
