I am using centos 6.2 guest on a Mavericks host in VirtualBox 4.2.18.
The guest was working fine for maybe a few dozen sleep/wake-up cycles. But then the internet connectivity mysteriously disappeared. It has not returned again on multiple additional sleep/wake-ups.
Here is networking info:

UPDATE After stopping the VM and restarting networking came back up. But .. is there a way to revive the internet connection without a restart?
I have this same issue. Any luck? – thesmart – 2014-08-13T17:51:32.737
Networking on virtualbox seems to be hit and miss. With an Ubuntu Host - and the same CentOs Guest - I end up doing sudo service network restart pretty often. As mentioned here, on mac the solution is worse. – javadba – 2014-08-13T18:23:53.373
I ended up running this on Ubuntu guest every time host wifi changes:
sudo dhclient -r && sudo dhclient eth0
and also using the bridged adapter. – thesmart – 2014-08-27T23:47:04.187@thesmart I did something along the same lines: sudo service network restart – javadba – 2014-08-28T04:27:38.743
I have the same issue with a centos virtualbox on windows 8. Hey! sudo service network restart works! Since ya didn't make it an answer, ima steal it ; ) (feel free to steal back) – B T – 2014-09-08T18:32:46.170
