Hello All,
I have one CentOS 6 KVM virtualization server that I built around a year
ago (best I can tell it was in October 2012) at which time I would have
been installing 6.3 [0]. That particular install used the Consistent
Network Device Naming [1] conventions (PCIe NICs are p1p1, p1p2).
I started to build out a new KVM virt server (kickstarting a 6.4 install
now as compared to 6.3 back then) and the interface names are back to the
old ethX convention for the PCIe NICs. See below for my snippets from udev
persistent rules on the two hosts.
I'm working off of [older] Dell PowerEdge 2950 hardware that has dual
onboard Broadcom NICs and an additional Intel Dual GigE PCIe NIC.
** Did anyone but me notice this change/regression in network interface
naming?
** Does anyone know if or why a change was made from what 6.3 or earlier
apparently defaulted to?
This is by no means a major problem, but it did make me wonder what caused
or why there was a change. [Of course I can change interface names in the
udev rules if I chose to.]
Thanks for your feedback!
