Thread: Another Bridging question, this one -is- different!

greetings,
i'm experienced linux user (been using linux since 1998, when setting x took hours, , downloading iso took days , days).

decided use ubuntu recently, since seems well-supported , relatively polished , up-to-date (debian proper moved slow, gentoo support being in mosh pit).

have beefy hardware running virtualbox, , i'm serving drive out iscsi target file server vm imports target local disk, lets me 'snapshot' state of system disk of virtual file server, not have snapshot data serves (which lead giant, slow snapshot files). have several other vms running sorts of stuff, feeding-off files on served 'server' vm.

problem have vms need visible hosts on lan, have them set virtualbox's 'bridged connection' eth0. not issue, both iscsi , vm-vm cifs traffic traversing physical wire, making things slower , incurring more overhead should.

since host iscsi target (read: server), , vms servers , clients, , there real physical clients on lan, i'd set bridge keep vm-host , vm-vm traffic -off- lan @ layer 2 (basically, having ' ethernet switch' inside computer.

think have plan, have no idea how implement it:

want bridge (lets call br0) eth0 connecting 'outside', , virtual interface (called v0) that's connected bridge, vms , dhcp client run on v0, traffic didn't need leave bridge never make onto physical wire.

here's problem:

code:

lan---switch---host(eth0, 192.168.1.10)                       |---vm(bridged eth0, 192.168.1.x)                       |---vm(bridged eth0, 192.168.1.x)                       |---vm(bridged eth0, 192.168.1.x)

and here's idea solution:

code:

lan---switch---host(eth0, no ip)                       |---br0                              |---host (v0, 192.168.1.10)                              |---vm(bridged br0, 192.168.1.x)                              |---vm(bridged br0, 192.168.1.x)                              |---vm(bridged br0, 192.168.1.x)

can tell me how go doing this? seems bit more in-depth other forum posts i've read on, 'no ip on eth0' idea, pushing host's networking behind bridge on host itself.

ugh. graphical description didn't quite work out, formatting got filtered-out. hope description good-enough.
