Hi
I trying to set up a network configuration using libvirt
The setup is:
1. a VM using virtio using a tap device connected to a bridge device
2. on the host side eth0 added to the same bridge device(without ip)
using libvirt application (say virsh) I want to launch this set up:
virsh net-create for the second part
virsh create for the first part(tap, virtio, vm etc)
I can set the first part(vm, tap, virtio) using the domain xml
but I'm also interested in XMLing the second part and net-create it.
I tried but only suceeded in creating the bridge
Is it possible? am I missing somthing?
Thanks in advance

This isn't what the net-XXX commnads is for. The functionality you are
after is in process of being implemented and will appear as iface-XXX
commands (for host interface managment)
For more info about libvirt networking, read this page

Thanks Daniel
Those iface-XXX commands
can I use them(partly) now?
or
where can I see their spec/xml template?
Thanks
Shahar

Some parts of the code are committed to CVS, some parts have been
submitted to the list and ACKed, but not committed yet, still other bits
have been submitted for comments, but aren't yet ready to be committed.
So I guess the answer is "no" for now, but "yes" *very* soon ;-).
If you want to look at the patches yourself, search for "virInterface"
in the list archives.
The XML is also not yet stable (there's been a lot of discussion about
that during the last week). Currently, the XML for libvirt virInterface*
is identical to the XML used by libnetcf:
https://fedorahosted.org/netcf/
libvirt will be using netcf as the backend to implement all the
virInterface functions.
11:05 p.m.
I tried the virInterface that is already in 0.6.4
but got this:
libvir: error : this function is not supported by the hypervisor: virInterfaceDefineXML
ERROR virInterfaceDefineXML
Can I use netcf just to get the feeling of it?
I mean use netcf as an admin user
i.e. define an XML that for example say somthing like that:
"define tap device tap8 and vlan 3888 over bond1 and add these two to bridge
br12"
can I do that with netcf?
thanks again
shahar

Of course, the code is available there..
https://fedorahosted.org/netcf/
We simply haven't finish plugging it into libvirt

netcf doesn't concern itself with TAP devices - those are related to
guest domains. netcf does allow you to configure anything you would
traditionally do via /etc/sysconfig/network-scripts (or /etc/network
on Debian). So creating bridges on VLANs over bond devices, and
that kind of thing.

Correct me if I'm wrong but it seems that the vlan support is not in netcf yet...
