I'm trying to get a 3.6.1 HE setup going where I have 4 VLANs (VIDs
101-104) for storage networks, 1 VLAN (VID 100) for ovirtmgmt and 1
more (VID 1) for everything else. Because I know of no way to

looks like:<br></div></blockquote></div><br></div><div class="gmail_extra">Why do you think of this necessary pre-work?
