#3135 closed defect
time inside guest fluctuates — at Initial Version
| Reported by: | Costin Grigoras | Owned by: | |
|---|---|---|---|
| Component: | other | Version: | VirtualBox 3.0.6 |

Description
Host:
OS: Ubuntu 8.10, 64bit, VirtualBox 2.1.2 (was also 2.1.0 and had the same problems) HW: HP DL360 G5, dual Xeon X5450, 16GB RAM
Guest: 64bit
OS1: Scientific Linux CERN 4.7 (Fedora Core 3), Kernel 2.6.9-78.0.8.EL.cern OS2: Scientific Linux CERN 5.2 (Fedora Core 6), Kernel 2.6.18-92.1.18.el5
Time is running too fast inside the guest, and vboxadd-timesync keeps bringing it back. Below is a sequence of commands ran at ~1sec interval:
# date Fri Jan 23 23:55:33 CET 2009 # date Fri Jan 23 23:55:35 CET 2009 # date Fri Jan 23 23:55:37 CET 2009 # date Fri Jan 23 23:55:34 CET 2009 # date Fri Jan 23 23:55:36 CET 2009
Guest: 32bit
Same OSs, but 32bit installations
Here the time flows correctly only if the guest OS is busy. If the guest is idle, time flows very slowly and the time sync daemon brings it forward a lot.
Other remarks:
Guest additions are installed and have the same version as the host virtualbox installation.
CPU frequency scaling is disabled, all cores run at full speed.
