[CentOS] network intermitent, not sure if virtualization issue- not solved

I am thinking adding ethtool opts wol pumbg
(wake on lan, all on)

the ethtool for eth0 on my vm said wol = d, never wake up.

so I set it in the ifcfg to just wake on everything.

will see, that may be the issue. Hopefully.

why in the world would the system set up a webserver install with a lan 
that is not alwys on though?
