So, I noticed there's about a 10 minute drift on my VM hosting server from what time it's supposed to be. In traditional environments, I would just restart the system (and change the BIOS time if necassary).
The hosting server is Ubuntu 12.04. Undertsanding that some process could be time sensitive (NTP?), I was wondering how this might affect the relation between the host and hosted system (currently hosting 4: 3 Ubuntu 12.04 servers with one being a web server, and 1 Windows Server 2008 file server). I am using Virtual Box 4 with it's headless option.
Ultimately, I am trying to avoid from shutting down the host (which ultimately mean shutthing down the other hosted systems). Is this safe?
