ESX 4.1 Host Profile Copy
Wouldn’t it be nice be able to make a copy of an existing host profile allowing you to create new profile?
vCenter Server 4.1.0 doesn’t have a copy function but you can export the profile then import it with a different name.
Note – Keep in mind this might not work on your destination hardware, you should use a base profile that is simlar and go fromt there. You also might have to tweek the copied profile for it work properly.
In vCenter Server 4.1.0 go to the Host Profiles area on you vCenter server
Simply right click and choose export profile
Choose ok to this warning…
Choose a good name and click on save
When the creation is complete from the main window Choose “Create a new host profile” > Import Profile >, Browse to the Import location and choose your file > Enter a new Name for the profile > Choose Finish
Once your done you can now edit this profile, updated it, add hosts, etc..

Virtual Datacenter Verify that hosts within a cluster maintain a compatible and homogeneous (CPU/mem) to support the required functionality for DRS, DPM, HA, and VMotion
Virtual Datacenter Check that FT primaries are distributed on multiple hosts since FT logging is asymmetric
Virtual Datacenter Verify that hosts for FT are FT compatible
Virtual Datacenter Check that reservations/limits are used selectively on VMs that need it and are not set to extreme values
Virtual Datacenter Check that vCenter Server is not running other applications and vCenter add-ons (for large environments and heavily loaded vCenter systems) and is sized appropriately
Virtual Datacenter Check that the DB log setting is Normal unless there is a specific reason to set it to High
Virtual Datacenter Check that the vCenter statistics level is set to an appropriate level (1 or 2 recommended)
Virtual Datacenter Check that appropriate vCenter roles, groups, and permissions are being used
VM Check any VMs with CPU READY over 2000 ms
VM Check any VMs with sustained high CPU utilization
VM Check any VMs with incorrect OS type in the VM configuration compared to the guest OS
VM Check any VMs with multiple vCPUs to make sure the applications are not single threaded
VM Check the active Swap In/Out rate of VMs to make sure it is not consistently greater than 0
VM Check that NTP, windows time service, or another timekeeping utility suitable for the OS is used (and not VMware Tools)
VM Check that VMware Tools are installed, running, and not out of date for running VMs
VM Check VMs that are configured and enabled with unnecessary virtual hardware devices (floppy, serial, parallel, CDROM) and any devices that prevent VMotion
VM Check VMs that are not yet on virtual hardware v7
VM Check VM configuration (memory reservation) for VMs running JVM to consider setting reservation to the size of OS+ java heap

Book – VMware vSphere 4.0 Quickstart Guide
I bought this book today… based on some blog posts I found (see below).
I must say it is one of the best.. It is a pocket reference so be aware the print is a bit small…
Download the Power-CLI Scripts from the book here…

Here are some notes about the book.. From this URL…
http://www.boche.net/blog/index.php/2009/11/23/vsphere-4-0-quick-start-guide-released-on-amazon/
What a great way to kick off the new week – The highly anticipated book, vSphere 4.0 Quick Start Guide: Shortcuts down the path of Virtualization, has arrived at Amazon.com! I look at this new release as the 2nd edition or vSphere edition of RapidApp’s Quick Start Guide to ESX 3.0 which is still available and was a huge success.
The vSphere 4.0 Quick Start Guide was written by a lineup of new authors who are well known rock stars in the virtualization community: Bernie Baker, Thomas Bryant, Duncan Epping, Dave Mischenko, Stewart Radnidge, and Alan Renouf. I obtained a preview copy of this book at VMworld 2009 in San Francisco and I can tell you that this it is absolutely amazing. Nowhere else will you find as much information in such a small and convenient footprint. Its small size allows you to put it in your pocket and take it virtually anywhere: On the plane, on the bus, into a meeting, or into the datacenter. As with the first edition, there are several blank pages in this book which allow you space to write down notes, command line information, configuration maximum changes, information about your environment, helpful URLs, etc. The authors did a great job on this book and considering the cumulative years of experience and combined expertise packed into this book, you can’t beat the price. I don’t think a better value exists. My copy has been traveling with me daily in my laptop bag. I give it two thumbs up.
VMware KB: Enhanced VMotion Compatibility (EVC) processor support
Check out this great article on EVC… lots of great information and links!
VMware KB: Enhanced VMotion Compatibility (EVC) processor support: “Enhanced VMotion Compatibility (EVC) processor support
Details
Enhanced VMotion Compatibility (EVC) simplifies VMotion compatibility issues across CPU generations. EVC automatically configures server CPUs with Intel FlexMigration or AMD-V Extended Migration technologies to be compatible with older servers. After EVC is enabled for a cluster in the VirtualCenter inventory, all hosts in that cluster are configured to present identical CPU features and ensure CPU compatibility for VMotion. The features presented by each host are determined by selecting a predefined EVC baseline. VirtualCenter does not permit the addition of hosts that cannot be automatically configured to be compatible with the EVC baseline.”
TalkShoe – Call – VMware Communities Roundtable
I found this really cool little community today thanks to a fellow VMUG User (Vlad N)
They have some really cool stuff..
