Create and manage a SDDC on VMWonAWS

This end of week i had the chance to participate in a really nice training : VMware on AWS : Deploy and manage.
I’ll try to perform a serie of blog posts around this trendy topic that i performed along this formation.

What it look to create a new SDDC into VMware on AWS?
First, let’s connect to vmc.vmware.com And click on “Create SDDC”

It’s quite simple but you have few choices to perform :
AWS Region : In my case I picked, EU (London), you may choose between many AWS region. Below find some detailed informations on this :

Deployment : Single host is possible but only for 30 days. In my case, i’ll pick multi host.
Strech cluster allows you to create your SDDC stretched out between two zones to create an SDDC that is highly available, fault tolerant and scalable.
SDDC Name : Simply the name that you’ll give to your SDDC
Number of hosts : Choose between 3 or 4 in your first cluster, you will be able to scale out your SDDC with another cluster up to 16 hosts.
Cloud : Option that you can’t see in production. 
Zerocloud is dedicated to training environment. It allows you to create “fake” SDDC. Nothing will be deployed at the end of this operations.

NSX : Communication Channels Down

As explained in a previous blog post, I’m working on NSX these days. I’m still performing some setup on my NSX Lab. 

The NSX lab is a nested one, with 4 ESXis.
One cluster for management, one for workload, 2 ESXis in each cluster.

I started to deploy NSX services on the management cluster and I had an issue when I deployed VXLAN.
One of my ESXi had an issue with communication channels, it was simply down :

NSX 6.4.4 : Full HTML5 support… or not

Mid of december, last version of NSX-V came out. One feature that was really expected was the HTML 5 full support.
On my side, i just came back from one week training on NSX : Install, configure and manage. My goal for the coming weeks is to pass the VCP-NV.

This week i started to build a lab : vCSA 6.7U1 / NSX Manager 6.4.4 / 4 nested ESXis on 6.7U1 too.

Today, i was really surprised that i was not able to use my licence key on NSX solution trough the HTML5 client, key isn’t visible:

Vulnerabilities : Access ESXi shell from a VM

Since a long time, many of security experts said that it may be possible to access to the ESXi shell trought a VM. No one had the ability to demonstrate this. This time is ended.

During the “GeekPwn2018”, Zhangyanyu from ChaitinTech company demonstrates this critical vulnerabilitie.

He get the skill to demonstrate how to do it, here a quick video from Julien Mousqueton’s Channel :

He used memory stack uninitialized in vmxnet3 to put code and execute it on the host. If you are using E1000 no issue with it.

If you need further details on this, you may check the official communication from VMware:
https://www.vmware.com/security/advisories/VMSA-2018-0027.html

In order to solve this vulnerabilitie, you’ll need to install ESXi670-201811401-BG patch.

We’re waiting this since VMworld US : vSphere 6.7 U1 is out since few days, and this new version brings some really new cool features.

First update your vCSA, go into the Management page and in “update” section select “6.7.0.20000”. The update is cumulative one so don’t worry about the other.

Homelab Upgrade : vSAN powered

vSAN is here from few years now, i already worked on it and i don’t take risk to say that’s a powerful technology.

I’m not really an expert on this topic and i want to go further, but as you may know, vSAN need “important” hardware. This solution, in my humble opinion, become nice to lab on it if you have at least SSDs and NICs dedicated to it.

NUC is for me one best solution to have your home lab, low footprint, low electrical consumption and really low noise, but you have drawback : my version is limited to 16 GB each and only one NIC adapter.

vSphere 5.5 is dead, long live vSphere 6.7

Everything is in the title, vSphere 5.5 is dead.

As described here by VMware end of support will be september 19, 2018.

What should you do?

Upgrade to vSphere 6.7 is THE choice i think, if you’re not confident with the last version of vSphere 6.7, you can go to vSphere 6.5.

Prerequisites?

Not so much to say, the thing to notice is that “Windows Client” is no more available, only web client.
HTML5 client is really handsome, Flex client aka Flash client is also still available, but new features will only be available trough the HTML one, so go directly with this one.

If your vCenter is in 5.5 and hosted on a Windows VM,  you can now go to vCSA version, in fact you must go for it, update manager is now packaged on it.
