ubuntu-10.10

This is taken from an Ubuntu 10.10 VM running on ESX5:

Nov  3 21:58:50 server1 ntpd[21169]: adjusting local clock by 31.187370s
Nov  3 22:02:36 server1 ntpd[21169]: adjusting local clock by 31.159808s
Nov  3 22:05:18 server1 ntpd[21169]: adjusting local clock by 31.067579s
Nov  3 22:07:59 server1 ntpd[21169]: adjusting local clock by 30.952187s
Nov  3 22:11:38 server1 ntpd[21169]: adjusting local clock by 30.890147s

According to the VMWare KB no kernel tweaks should be needed for Ubuntu 10.10 to maintain time to their standards.

What's especially odd is the drift seems fairly consistent.

Any help appreciated on this one!

VMWare ESXi, change the default path for a VM

For some reason VMWare ESXi has decided that one of my VMs is on a completely different path to the path it is actually on.

Yes, I know running a virtual machine inside of a virtual machine is a bad idea. Yes, I know it will be very slow.

I'm almost embarrassed to ask this, but I'm stuck. I installed VMWare ESXi on a Mac Pro. It's working great! The problem is that you press F12 to eject the disk, and F12 is what you use to shutdown ESX. I can power down, open the case, pull out the CD drive and use a paper clip to force the drawer… >>> More
