I have created at PowerShell script that obtains a list of VM’s that have snapshots attached. The output is then converted to a html file using the cmdlet ConvertTo-HTML.
And just to make it easier to obtain the html file, the script mails the html file to me as an attachment.
Get the script from the Downlaod section.
Today i came across an article from techtarget.com about securing and auditing VM’s and ESX hosts.
There are a few free tools that can help you audit your host servers. Tripwire’s ConfigCheck and Configuresoft’s Compliance Checker for ESX, both of which are lite versions of each company’s enterprise-level product.

VMware has released a video comparing the two installations.
The video is worth watching

A few weeks ago we were conducting a vRanger DR test of a VM (new host and new LUN).
The VM was restored succesfull, but when we powered it on we discovered that it for some unexplaned reason had lost the SCSI0:1 (100GB) and SCSI0:2(300GB) VMDK’s.
It had created two new 20GB VMDK’s instead.
We searched the LUN and found the two orginal *-flatvmdk files but not the descripter files.
Use Putty to identify the size of the *-flatvmdk file. ex. 100GB
ls -lah
From a VM (not running) create a new disk with the same size as the one you are missing. The name is not important.
Locate the newly created *.vmdk and *-flat.vmdk file. Copy the new *.vmdk file to the folder that contains the orginal *-flat.vmdk file.
cp rescue_me.vmdk /vmfs/volumes/mysan/rescued/rescued.vmdk
Use VI or NANO to change the following line as below from:
RW 419426200 VMFS “rescue_me-flat.vmdk”
To:
RW 419430500 VMFS “rescued-flat.vmdk”
Make sure that the name of the .vmdk file correspond to the SCSI*:*.fileName in the vmx file.
Now just power on the VM and the orginal disks are intac.
The past few days I have been trying to learn the basic of PowerShell and the VIToolkit for Windows.
And after playing around with it, I thought that the best way to learn PowerShell was to have a goal.
And what better goal than converting the vcinfo script I created with VIPerlToolkit.
A beta version of the script is now avaiable for download - get it here.
But I have to warn you - the script is still in beta.
I have added a few of the old information and some new ones.
More info will be added when I get the time.
If you have any suggestions on what info the script should show in VC, please let me know.
I was surfing around for new powershell scripts and came across an application for icomasoft that gives you the abbility to add and run your own PS scripts from Virtual Center.
Thyis is just too cool.
Check it out.
This isn’t new!
But what is new, is that it’s now possible to run VM’s inside the hosts.
The performance isn’t the best, but it’s OK for testing.

Today I came a cross 2 possible solutions for upgrading the VMware Tools for Linux guests.
One soultion is using a custom scripts in the guest to upgrade the tools.
The second solution describes how to use Virtual Center to upgrade the tools.
The article also describes some of the advanced options parameters you can use to control the tool upgrade.
Read the entire article here.
This morning we experienced major network problems and this resulted in one of the hosts generating a PSOD.
After a restart of the host everything worked fine.

“This first VMware® VMbook focuses on Business Continuity and Disaster Recovery (BCDR) and is intended to guide the reader through the step-by-step process to set-up a multisite VMware Infrastructure that is capable of supporting BCDR services.
The VMbook will provide very valuable insight into the considerations and design principles for a multisite virtual infrastructure data center that leverages array based replication for the replication of VMFS datastores; which is one of the prerequisites for Site Recovery Manager 1.0. The VMbook authors suggest your customers leverage this VMbook as a reference even if they are planning to implement a Site Recovery Manager based BCDR solution day one, as the BCDR solution detailed in this VMbook provides design principle guidance for a successful multisite virtual infrastructure data center deployment which is the underpinnings for a successful SRM deployment.”
