The solution are pretty simple.

Option 1:
1. Turn OFF VMware HA on Cluster Feature setting.
2. Enable VMware HA setting again.

Option 2:
1. Enter maintenance mode
2. Remove ESXi hosts from cluster
3. Add ESXi hosts back to cluster
4. Exit maintenance mode

Done! The annoying warning message will go away.

I would like to share How to disable or turn off beep speaker sound on VMware Workstation.

1. Look for virtual machine DOT VMX(.vmx) file.
2. Edit virtual machine .vmx file.
3. Insert

“mks.noBeep = “TRUE””

4. Save .vmx file.
5. Power On virtual machine.

For an example, my OpenSuSe 11 DOT VMX file save in drive D:\My VM\OpenSUSE11\ folder as show below.

Enjoy!

Due to certain requirement, you may need to clone a snapshot taken sometimes ago and you can make as many copies as you need.

This guide show how to making a clone from a snaphot on VMware Workstation 6.5.

Note: The snapshot MUST BE from a virtual machine that is powered off.

Open VMware Workstation 6.5, click on VM tab, click Snapshot, click Snapshot Manager or CTRL+m.

Click clone.

Click Next on Clone Virtual Machine Wizard.

Click Next Clone from The current state in the virtual machine.

Click Create a full clone and Next.

There are 2 types of clone:
# A full clone is an independent copy of a virtual machine that shares nothing with the parent virtual machine after the cloning operation. Ongoing operation of a full clone is entirely separate from the parent virtual machine.
# A linked clone is a copy of a virtual machine that shares virtual disks with the parent virtual machine in an ongoing manner. This conserves disk space, and allows multiple virtual machines to use the same software installation.

Enter Virtual machine name, Location and click Finish. You’re done!

I’m sure you will ask making a clone from a snapshot for VMware ESX Server. Just do a live clone and revert to snapshot taken or you may refer to VMware Communities Forum.

Enjoy!

Our design for a storage on ESX is 300GB, allow maximum VMFS up to 256GB.

The reasons behind are:

• better I/O performance: Each storage in ESX, we only assign to 5 VMs or less. Since more running VMs on a single storage will hit into the LUN I/O speed bottle neck.
• better disk utilization: You can safe lots of unuse space when you do it small. Say You assign a 2TB storage that can keep 40 VMs, but you only have 20 now, you actually waste 1TB which is sitting there doing nothing. But if you make each storage small, you can create only when you need it. It is much more manageable on SAN disk allocation point of view.

You may ask, if we need a disk in VM that is larger then 256GB? Well, up to that size, you need to consider I/O performance as well, VMFS is just not capable for that size if you are looking for performance as well. Normally we assign a RAW Device for that, you can connect a RAW up to maximum 2TB disk space if required. Check VMware VMFS vs RDM.

Solution:

Option 1:
Power off the virtual machine

Option 2:
Edit setting -> click SCSI Controller 0 -> click ‘NONE‘.
