I have never had much luck with clock synchronization (of Linux guest hosts)
running 64-bit VMware Workstation on CentOS 4.6 server. I have tried all
the runtime kernel parameters, compiling custom kernels, using VMWare tools,
and every other option I have found on the VMware site, but nothing has
worked well for me. I usually wind up setting up a cron job to synch to the
server every 5 minutes or so. Horrible hack, but it is the only thing that
has worked for me.
On the other hand, I have had no issues with VirtualBox (with either Windows
or Linux guests). I run both VirtualBox guest and VMWare guest OSes
side-by-side without too many issues. I do not have any 64-bit guests, so I
am not sure if things are better in that realm.
The clock synch issue in VMWare has always plagued me.
