Re: Install not working for SLES11 SP4 thru TRUNKED VSWITCH

So, If you make sure you have NATIVE NONE and keep track of your grants (just like PORTBASED) there is no real security concern... The guest is only allowed the vlans you grant it (just like PORTBASED) and he cant send any untagged frames. I would rather manage a USERBASED VSWITCH with trunks over
