[libvirt-users] Isolated networks && test lab

[Spanky Horawitz]

Thanks again!

Can you tell me the difference in setting things up that way as opposed
to updating (in Ubuntu) /etc/network/interfaces and adding physical
br(idge) interfaces?  On my other test box, I setup networks the way you
describe from https://help.ubuntu.com/community/KVM/Networking

virt-manager is what I'm talking about (don't know what you mean by
"VMmanager"). Probably the dialogs have changed - mine is v1.2.1. 0.9.5
sounds a bit old, you should see if there is a backport of a newer
version somewhere for whatever distro you're running.

Alternately, it is dirt simple to create a new network that has no IP
address associated with it. Just do this:

1) create a file with these contents:

    <network>
      <name>mynetname</name>
    </network>

2) "virsh net-define filename.xml" (where filename.xml is the file
containing the above XML)

3) "virsh net-autostart mynetname; virsh net-start mynetname"

(all these run as root)
