I have noticed that with the default install of Red Hat Linux EL 5 a lot of services/daemons are running that DO NOT need to be. These services can “eat up” resources; and, in some cases, cause stability issues.
Here is the list:
* hidd – Human Interface Daemon for Bluetooth.
* bluetooth – Bluetooth Daemon.
* smartd – Disk Drive monitoring service. Not needed on VM guests.
* cups – Linux printing Daemon.
* ip6tables – IPv6 firewall Daemon.
* iptables – IPv4 firewall Daemon.
* avahi-daemon – Facilitates service discovery on a local network, Bonjour, Win-Plug-N-Play.
* libvirtd – Xen virtualization framework. Starts mDNS daemon and DHCP server. PLEASE turn this off.
* rhn-virtualization-host – Xen virtualization framework. PLEASE turn this off.
*** You can view the state of these services by typing:
# chkconfig –list | more
# chkconfig –list | grep
Ex: chkconfig –list | grep cups
You will then see the current state of each service at every run-level.
*** To disable these services type:
# chkconfig off
Ex: chkconfig cups off

FYI:
When you need to install Microsoft Windows Vista in a VM guest you will need the following file:
Use this file when the installer complains that it does not have proper drivers for the CD/DVD ROM drive.

There is an issue with some NICS (especially older Compaq G1 ones) where the VMware Converter process hangs at 2%, status = “In Progress”.
Setting the switch port and NIC to Auto Speed/Duplex will resolve this issue.
Please see the VMware discussion article:

This was a similar issue with VMware P2V:

This error is caused when your Virtual Center Client application cannot directly (over IP) connect to your ESX host. I see this a lot of times when you are installing the VMVC Client on a new workstation.
The “fix” is very easy:
1) Add your ESX hosts into DNS. -not a bad idea in the first place
*** OR ***
2) Edit your Microsoft Windows hosts file to add your ESX servers for name resolution.
* Found in “C:\Windows\System32\drivers\etc\host” — Just edit with notepad.exe
3) Reopen your client and try again.
Now, if you are traversing a firewall, you may need to open some ports: All the ports needed are open (80, 443, 902, 903).

Greetings,
If you never needed to reset a forgotten/corrup Windows administrator password, here is a link and ISO that totally works great. Works fine on Windows-based VMware guests.
*** As always, use this application/method at your own risk… Always remember to do backups of your sever ***

If you ever wanted to enter (or exit) the VMware ESX Maintenance Mode, you can do this using the VIMSH command. See below:
- To Enter Maintenance Mode on ESX HOST:
vimsh -n -e /hostsvc/maintenance_mode_enter
- To Exit Maintenance Mode on ESX HOST:
vimsh -n -e /hostsvc/maintenance_mode_exit

Want to rename a VM guest?!? Sure you can manually edit the *.vmx, *.vmdk files — but here is an easier way:
#1) Shutdown your VM guest.
#2) Right click, then Rename in Virtual Center.
#3) Right click, then choose Migrate…. Do a “cold” migration to another Datastore with enough space for your VM guest files, *.vmx *.vmdk’s, etc.
#4) After this finishes, you can move back to the original location, if you want.. — All of your VM guests files will be properly renamed.
#5) Power on your VM guest.
* Only thing you have to watch is to make sure you have enough free disk space on the Datastore you are moving to.

HGFS is disabled in the host (on boot, in logs, when restarting NFS/mounts)
SR Description: Getting error on a Linux VM guest, kernal vmware HGFS, HGFS is disabled in the host.
*** HGFS mounts allow the VM guest to connect to a share hosted on the ESX server/host. It is installed when the VMware Tools service is installed. This is a non-essential process and can be removed from /etc/fstab on the VM guest.
You can comment out the line that starts with .hosts…
