[libvirt] only 256 active networks

[Dan Kenigsberg]

Hi List, Laine,

Maybe you can help here.

We define 256 bridged networks such as

    <network>
      <name>vdsm-test244</name>
      <uuid>c3acd4c3-37be-3f9d-ee6b-317513015f9e</uuid>
      <forward mode='bridge'/>
      <bridge name='test244' />
    </network>

and end up killing `virsh net-list` with

    error: Failed to list active networks
    error: too many remote undefineds: 257 > 256
    error: Reconnected to the hypervisor

What is this limitation? Why is it there? How can this be extended/avoided?

Dan.
