I think there are two problems: (1) On the Chromium server nodes, you are not running crserver on the root display. For instance, when you SSh into pc1 and pc2, you need to set DISPLAY=:0 before running crserver. This is perhaps unclear in the VirtualGL documentation.
(2) Before you can run anything on display :0 on pc1 or pc2, you need to grant access to that display. That means either logging in on both of those machines or using vglserver_config to enable X server access while the machine is sitting at the login prompt.
