What does "lose a NIC" mean? Does it mean that device doesn't show up
at all, and is not apparent with "/sbin/ifconfig -a" ? Or does it mean
that the device is not properly configured with IP address and
connected to the local network?
I've certainly noticed with various virtualization systems and CentOS
6 that sometimes DHCP doesn't get configured in the very short time
between the VM booting and the prompt being available. It always
recovers with a "/sbin/service network restart".
