VirtualBox: How to sync host and guest time

virtualbox

The time in my guest VM is faster than the host time by about 20-30 minutes. What can can I do so that the time in the guest is the same as on the host?

Best Answer

For a Linux host, first install the DKMS (Dynamic Kernel Module Support) package on the guest machine (source):

$ sudo apt-get install dkms

Then install Guest Additions into guest system:

$ sudo apt-get install virtualbox-guest-additions

Also, here are descriptions of some commands to tune VirtualBox time synchronization.
