Re: Not all interfaces come up

We had the same issue here, and after a lot of work we think that the =

problem is with the LAN driver. Pulse try to get up the interfaces more =

fast than the driver can handle and some IPs dont get up.

Our "solution" was install RedHat but over XenServer, the hypervisor =

handles the interfaces without problems.
