Hello Andrew! Many thanks for your reply! It's very good to see an environment like my! I'm using RHEL 5.2 with kernel-2.6.18-92.1.22.el5... can you explain a little bit around this trick divider? I'm usually have 2-3 IBM x3850 (16 cores CPU and 128 GB RAM) with 10-15 virtual machines running under GFS, with a LUN ~500 GB SAN. My problem happens when Multicast: Switch -> GFS -> Switch = OK vSwitch (Box_A) -> Switch-> vSwitch (Box_B) = NOK Did you have some problem with? If I put all VMs inside the same box (vSwitch Box_A -> vSwitch Box_A) I don't have any problem... Thanks a lot! -- Tiago Cruz <tiagocruz@xxxxxxxxxxxx> On Tue, 2009-06-30 at 10:37 -0600, Andrew A.
