Description Erik de Castro Lopo 2010-04-24 05:48:58 EDT
Description of problem:

There is currently no support for VDE2 networked machines. 

Eg, when running:

    virsh domxml-from-native qemu-argv run.argc

with a run.argc file containing:

    kvm -nographic -m 1024 -hda /path/to/img.qcow2 \
      -net nic,vlan=0,model=rtl8139,macaddr=52:54:16:32:43:21 \
      -net vde,vlan=0,group=vde2-net,mode=0770,sock=/var/run/qemu-vde-ctl

the second -net lines gets silently dropped from the generated XML file.

I'm sure this is not the only aspect of VDE networking that isn't supported.

Patch adding vde support to libvirt (against 0.10.2)

This basicallay forward ports the patch origanally posted

A followup message to that suggested that this would be better handled by using vde to handle the network definition for user virtual machines. While I think that is also worthwhile, I think this is also beneficial. For example, a priveledged user could create a vde_switch with access to the outside world, and allow users in a given group to create virtual machines that connect to that switch.

vde seems quite dead upstream these days. and given that there's been lots of work put in to making libvirt support openvswitch, there's already an alternative there. so I don't think it makes sense to explicitly track this anymore. closing
