I have setup PLoP linux to be PXE booted and am able to boot a VM over the network without issue. However, when I try to PXE boot PLoP on my Dell servers, after I choose the default option on the boot screen, PLoP cycles through each of the physical network interfaces and gives me the following messages:
ifconfig: SIOCSIFFLAGS: Device or resource is busy
Sending discover...
udhcpc: Sendto: Network is down.
Obviously DHCP is working or I wouldn't have been able to PXE boot in the first place. I've also added the dhclient command to the runme sh script but I imagine that is only run after the system is mounted via NFS and starts up.
