[Observium] VM and Observium

So, is anyone experiencing any issues running on observium on a vm? I submitted an email a month or two ago about some issues we were seeing, and i decided to reinstall observium from scratch. Currently i am seeing the same issues, whereby it "appears" that connectivity drops or isnt captured randomly. it's not across one device, but all. i am wondering if maybe i didnt build the vm appropriately or we really are having a network type issue. ive looked at the network but maybe i am overlooking something. anything on the vm side that maybe i can look at? i am running ubuntu 13.04 and the latest observium code as of yesterday.
