ESX 4.1 Host Profile Copy

Posted on Updated on

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..

Host Verify all host hardware is on the VMware Hardware Compatibility List (HCL)

Host Verify all host hardware meets minimum supported configuration

Host Check if any 3rd party agents are running in the ESX service console

Host Verify that NTP is used for time synchronization

Network Verify that networking in configured consistently across all hosts in a cluster

Network Check to make sure there is redundancy in networking paths and components to avoid single points of failure (e.g. at least 2 paths to each network)

Network If HA is being used, check that physical switches that support PortFast (or equivalent) have PortFast enabled

Network Check that NICs for the same uplink have same speeds and duplex settings

Network Check that Management/Service Console, Vmkernel, and VM traffic is separated (physical or logical using VLANs)

Network Verify that portgroup security settings for ForgedTransmits and MACAddressChanges are set to Reject

Network Check the virtual switch portgroup failover policy for appropriate active and standby NICs for failover

Network Verify that VMotion and FT traffic is on at least a 1 Gb network

Network Check that IP storage traffic is physically separate to prevent sharing network bandwidth

Storage Verify that VMs are on a shared datastore

Storage Check that datastores are masked/zoned to the appropriate hosts in a cluster

Storage Check that datastores are consistently accessible from all hosts in a cluster

Storage Check that the appropriate storage policy is used for the storage array (MRU, Fixed, RR)

Storage Check to make sure there is redundancy in storage paths and components to avoid single point of failure (e.g. at least 2 paths to each datastore)

Storage Check that datastores are not getting full

Virtual Datacenter Check that all datacenter objects use a consistent naming convention

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

Posted on Updated on

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…

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

Posted on Updated on

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

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.”

I found this really cool little community today thanks to a fellow VMUG User (Vlad N)

They have some really cool stuff..
