Here’s a handy PDF, showing a step-by-step procedure for resizing the “/” root partition on a Linux VM guest. Please note, that the guest was running a Red Hat based OS.

When using ESX VC Snapshot manager, it is a good idea not to leave your snapshot online for more than a day or two.
When a snapshot is left for more than 24-48 hours, disk “delta” files become very large and difficult to commit to the original Vmware vmdk disk file(s). This can lead to data corruption on your original vmdk file.
* When you go to delete a Snapshot, via Snapshot Manager, you may see the process get to 95% and then seem to hang—-then fail with the error: “Remove Snapshot: Operation Timed Out.” DO NOT issue another delete via Snapshot manager.
There is a background process that is still removing the old snapshot. Be Patient. When the process is completed, you will NOT see the snapshot listed in Snapshot manager. The -delta.vmdk files will also be gone.
Unfortunately, I’ve experienced this first hand.

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:

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 ***

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…
Thanks,
Will
