Eth1 is an xpci card sold by StarTech. A system with an identical
card reports this:
for BUSID in $(/sbin/lspci | awk '{ IGNORECASE=1 } /net/ { print $1
}'); do /sbin/lspci -s $BUSID -m; /sbin/lspci -s $BUSID -n; done

The 4 port serial controller on the second host does not have an
equivalent card installed on the host that no longer recognizes eth1.
The integrated NI is eth0 for both hosts and this i/f is integrated on
the Intel motherboard. The motherboards are the same model in both
hosts. Both system are configured as KVM hosts. Both are running
CentOS-6.3
