Hello, we just migrated to distributed switches for our VMs on a VMware 6 U2 cluster. Following the upgrade, our VMs are having trouble talking to each other when they are on different hosts. They can ping each other by name, but things like Windows traffic won't go through. Move the VMs the same host and they can talk just fine.
We've been on the phone for hours with VMware support and getting nowhere. Its an odd problem as this was working before the switch migration. But now even when we move the VMs back to standard switches the problems continue.
I know that's all pretty vague, but if anyone has some insight, I'd appreciate it.
