Vyatta - Final 6.0 with updated VMtools for vSphere 4.1

So its been a busy few weeks with all the news and related blog articles on vSphere 4.1
I finally got around to extracting vmtools 8.3.x and intergrating it into the Vyatta Appliance.

There is also something different with this release, the source code for vmtools has been modified to prevent Large Recieve Offload.LRO is defined as:

In computer networking, large receive offload is a technique for increasing inbound throughput of high-bandwidth network connections by reducing CPU overhead. It works by aggregating multiple incoming packets from a single stream into a larger buffer before they are passed higher up the networking stack, thus reducing the number of packets that have to be processed. In Linux, it is generally used in conjunction with the New API (NAPI) to also reduce the number of interrupts.

There have been a few users reporting an issue with LRO and others requesting the intergration of the latest version of here you go:

I would like a few people to test this release and let mw know how it goes before making it live on the VAM.

vSphere 4.1 and KB1011292

Hi everyone,

So I have been trying to get together some hands on 4.1 videos for you guys (and girls)
however KB1011292 has been my main reason for not upgrading.

What is KB1011292 I here you ask?:
"VMware View Composer 2.0.x is not supported in a vSphere vCenter Server 4.1 managed environment as vSphere vCenter Server 4.1 requires a 64 bit operating system and VMware View Composer does not support 64 bit operating systems.

VMware View 4.0.x customers who use View Composer should not upgrade to vSphere vCenter Server 4.1 at this time. Our upcoming VMware View 4.5 will be supported on VMware vSphere 4.1.

As you know the supported way of upgrading your vSphere enviroment is like this:
1) Upgrade vCenter
2) Upgrade ESX hosts
3) Upgrade vmware tools
4) Upggrade vm hardware version.

Therefore if you run VMware View 4 with composer your trip into 4.1 greatness is going to come grinding to a halt with step 1.

Having VDI is great however it makes upgrading a roll on VMware View 4.5 with your 64bit composer.

And for those not tide to VDI here is the Vsphere upgrade guide:

vSphere 4.1!

OK, so vSphere 4.1 is out! and now the embargo is lifted I can finally share some of the awesome new features in 4.1.

Now lets be honest there are so many new and cool features in 4.1 that most other companies would probably release it as a version 5.0!But VMware release it as a point release...and that's cool.

Enough of the chit chat you did not come here to hear how great VMware is, its more about what are these new features? Is it worth upgrading to? and are they worth all the fuss?

So the features:

and here is a summary of the features that I think really count and why:

1)Storage I/O control
Prioritized use of storage (similar to how compute is prioritized with vSphere)
this means you can now make sure that your "VIV"s or Very Important VMs get the IO they need when you have IO congestion. This is done via the I/O Shares within the VM properties.

2)Network I/O Control
Set different levels of service per Storage Flow type.
virtual machine, vMotion, FT, and IP storage traffic.
This means you can make iSCSI or NFS take priority over vMotion.
But there is a gotcha:
Enabled with Distributed Switch only and therefore Enterprise Plus only

3)Memory Compression
Slower than real memory but much faster than swapping to disk.
Improves the performance for the VM when under contention as far less memory is swapped to disk.

4)vMotion Performance Increases and Scale Increases
Allows up to 4 on a 1Gbps network and 8 on a 10Gbps network.

5) Storage vMotion Scale Increases
Allows up to 128 (both VMFS and NFS)

6) DRS Host affinity
Allows you set set rules on where your VMs vMotion to when DRS needs to move them.
e.g. VM W2003-DC1 only goes to DRS Group 1, however VM W2003-Exchange only goes to DRS Group 2.

Here is where you create the rules:

7)vStorage API for Array Integration
This is another great feature (if supported by your SAN),
essentially this means vSphere can interact directly with your SAN.
Therefore instead of copying the files from one datastore to another, it instructs the SAN to move the blocks for you! Increasing the performance for Storage vMotion and Provisioning VMs etc

Also noteworthy:
4.1 will be the last release for ESX (ESX Classic) from now on there will only be ESXi releases

The binaries are avalible now so go grab them!

Thanks for John Toyer@vmware

Download my videos!

Hi Everyone,

I noticed last night (and was messaged by a few people) that some of my latest videos seem to have been encoded in a lower resolution, therefore I have reencoded, reupped and reembedded these videos.

However I wanted to take this opportunity to let you know that one of the reasons I chose Vimeo is that you can download my videos for free!
Registration is much quicker than most, you can download all my videos and then play them back any time.

Once you register you will see a "Download Video" option on the right hand side.

Here are some links to get you started:

Setting up Windows 2008 Network LoadBalancing with vSphere

So I came across a few posts recently during my travels where a couple of
people were having issues with setting up Windows Network Load Balancing within
vSphere and in particular with Distributed vSwitches.

So here we go - how to setup NLB with IIS:

And here is the video:

3)Installing IIS
4)Testing for Failure
5)Going Through the vDS settings
