First, i did search and didnt see anything on this here.

I want to create intefaces to connect VMs to that are not bound to a physical interface.

I am using a vyatta VM to route between groups of VMs and dont want those interfaces attached to a physical interface.

Thanks in advance.

Simply create a new bridge - Or what exactly is the question?
Click to expand...


I create a new bridge...lets say vmbr9 with no bridge ports.

I then create a interface on my vm using that brindge. Reboot to apply changes.


When i try to start the vm, i get the following error and it fails to start.

.........hmmmmmm


so i typed the above and went to get the text of the error message and it worked.

i had done a re-install (the second one)......strange


never mind i guess.
 
actually it happened again but i have been able to isolate the issue.


the error is below and seems to happen when i create an interface to the bridge with a vlan. that makes sense to me but, as i am new to PM and experienced with ESXi, it presents some challenges to my typical virtualised network design.

no
physical interface on bridge 'vmbr99'
