if the CD is not mounted you can't import PXE files so that seems to be working.
as for the netstg2 error, that's unfortunately a common redhat error that doesn't seem to be easily solved. i get that too sometimes and it helps to move the EDA from vmware server to workstation or to ESX. or sometimes a different network card in the host or a different physical switch helps. no idea why this happens. if possible, try putting a crosscable between your host and the appliance (the host it runs on). at least you'll know it's got something to do with hardware.
i'm trying to find a fix for this because it's annoying even if it does only happen on one out of 10 setups. if i find it i'll put it in the next version.
