Back to Basics: Troubleshooting VM Network Connectivity

Sometimes those of us that have been doing virtualization for a while forget that others that haven’t been doing it don’t always know where to look at.  So, in this post I am going to go over the things to check when you are having issues connecting to a VM.

1.  First step to check is whether the OS has the proper network information, ip, gateway, subnet to get out.

2.  If step 1 is good, you then want to check under the settings of the VM and make sure that the virtual nic is connected.

3.  Next, check to make sure you are connected to the proper virtual network.  If you have a standard switch and a VDS, make sure you select the right one.

6.  Beyond this you would need to check the physical switch configurations to make sure it is configured properly for the traffic.

Vsphere 6 Announced!

This has been a crazy year for me both personally and professionally.  I was just awarded the vExpert 2015 award and I am greatly honored.  I am hoping to get more posts out this year so I can keep it running.

First post of the year will obviously cover some of this new announcement.  There are many changes and many of the experts in the industry have done a lot of work so I will just be compiling the list of links here.  As I get more acquainted with the technology and involved I will begin making more posts about it.

Here is a brief list of changes:

– Clusters can now support up to 64 hosts

– Vmotion enhancement: Long Distance Vmotion, Cross Switch Vmotion, and Cross Vcenter Vmotion

– Fault Tolerance Enhancement: Up to 4 vCPU’s supported

-VVOLS – VM-aware storage arrays

-Content Library – a new way to store templates/isos in a central repository that all Vcenters can use.

The year is winding down…..

Hope all had a good end of year and holidays whatever you celebrate!  It’s been a slow quarter for me on the blogging front.  Been quite busy both in personal and professional life.  I hope to get back into the swing of things after the new year!

A few things of note that are on the virtualization front that I hope to cover more in depth this upcoming year:

– Vmware’s cloud service Vcloud Air

– VCAC posts on configuration and creating blueprints

– Vsphere 6 (which I expect to be released sometime this year

See you all on the other side!

VCAP5-DCA Experience (VDCA550)

I took the VCAP5-DCA yesterday (passed) and I figured I would share my experiences and how I studied hoping that it might help others. The 5.5 version of the exam is only 2 hours not 3 like the previous versions.

Studying Methodology:

My studying methodology was quite simple and worked well for me to remember.  Basically, I just took the blueprint and lined it up next to a browser window with the Vsphere 5.5 documentation.  I also had my Vcenter/Vsphere lab up so that I could perform or look up where to complete the tasks in a live environment.  If you don’t have a lab you will need to invest in one if at all possible.  There are many blogs out there on building a home lab or you can also check out AutoLab.

As I went line by line through each of the objectives, I would both look it up in the documentation and also find where to configure it on the actual vsphere lab.  Going line by line did a couple things: one it forced me to actually pay attention to what I was reading and two commit it to memory.  There are already plenty of guides out there, but I didn’t feel just skimming them would commit it as well to memory.  I did reference some of the other sites out there on some of the topics that were slightly vague to get an idea of what they thought it was asking for.

After  I had reviewed the blue print, I used Joshua Andrew’s Test Track to try some mock scenarios and get a feel for what the test might look like.  Lastly, I looked for tips and trick blogs like this one to get an idea of what to look out for.

The Actual Exam:

I had read many complain on the speed of the the lab environment.  I will say it wasn’t insanely fast, but it also wasn’t extremely slow either.  I would recommend only staying logged into what you need to stay logged into to perform your tasks and that should help.  The first thing I did was right down the number for all of the labs.  As I went through each task, I marked down whether I completed it or skipped.  If I wasn’t 100% sure how to figure it out after about 2-5 minutes I would move on and plan on getting back to it.  This methodology worked very well and I was able to complete probably 17 of the 23 on the first try.  I had about 45m-1hr left at this point.  So, I went back and completed another 4.  I left 2 of them that i wasn’t real sure on knowing that I was confident in completing the other 21 tasks.

Feel free to message me with any questions and I will try and hep.

 

Vcenter and Vsphere 5.5 U2 released!

Here is the link to the release notes: https://www.vmware.com/support/vsphere5/doc/vsphere-vcenter-server-55u2-release-notes.html

Of major note to me, especially a proud supporter of the thick client:
Unable to edit settings for virtual machines with hardware version 10 using the vSphere client
When you attempt to perform the Edit Settings operation using the vSphere Client (C# Client) in a virtual machine with hardware version 10 (vmx-10), the attempt fails with the following error message:

You cannot use the vSphere client to edit the settings of virtual machines of version 10 or higher. Use the vSphere Web Client to edit the settings of this virtual machine.

This issue is resolved in this release.

Also database support updates:
vCenter Server database support: vCenter Server now supports the following external databases:

Oracle 12c. Important: For pre-requisite requirements, see KB 2079443.
Microsoft SQL Server 2012 Service Pack 1
Microsoft SQL Server 2014

Temporarily adjust the Customization Wizard missing from Web Client

It was brought up on the forums earlier this year and I have confirmed that this is an issue in Vsphere 5.5 U1.  There is an option in the C# thick client when trying to deploy a VM where you can select the a Customization Spec and then choose to temporarily adjust before deployment.  See screen below:

 

customization

This is a great option for those that want to keep most of the details, but maybe want to just change the IP address. This option appears to now be gone in the web client.  So, until it is resolved users will have to continue using the thick client for this.

If you look at the screenshots below, you can attempt to choose that option, but it takes you to a screen to create a brand new PERMANENT customization spec.  I plan on following up with VMware to determine if this was by design somehow.
