Thanks! Unfortunately, I am running into the following issue when attempting to use the generic ethernet configuration:
$ virsh -c qemu:///system create /tmp/generic.xml error: Failed to create domain from /tmp/generic.xml error: internal error process exited while connecting to monitor: kvm: -netdev tap,id=hostnet0: could not configure /dev/net/tun: Operation not permitted kvm: -netdev tap,id=hostnet0: Device 'tap' could not be initialized
This is the network part of my xml file:
... <devices> <interface type="ethernet"/> ... <interface type="ethernet'> <target dev="tap0"/> <script path='/etc/qemu-ifup'/> </interface> ... </devices> ...
In my /etc/libvirt/qemu.conf file I have the following set:
user = "root" group ="root" dynamic ownership = 0 clear_emulator_capabilities = 0 cgroup_device_acl = [ "/dev/null", "/dev/full", "/dev/zero", "/dev/random", "/dev/urandom", "/dev/ptmx", "/dev/kvm", "/dev/kqemu", "/dev/rtc", "/dev/hpet", "/dev/net/tun", ]
You did restart libvirtd after making those setting changes, right ? The user, group & clear_emulator_capabilities settings are the 3 that matter here & you have them correctly set.
I am running Ubuntu 12, which does not use SELinux.
It has apparmour though, which possibly denies access to /dev/net/tun Daniel -- |: http://berrange.com -o- http://www.flickr.com/photos/dberrange/ :| |: http://libvirt.org -o- http://virt-manager.org :| |: http://autobuild.org -o- http://search.cpan.org/~danberr/ :| |: http://entangle-photo.org -o- http://live.gnome.org/gtk-vnc :|
