VMware vCenter Server Appliance (VCSA) – How to Configure NTP

vmware

I’ve been working with VMware vSphere 6.5 recently on a few projects and had to make some minor tweaks to the vCenter Server Appliance (VCSA) to configure NTP and time synchronization. Here is a quick guide on how to change the NTP settings.

The change can’t be made from logging into the normal vCenter Server Appliance web client you would use for managing the cluster, you have to log directly into the vCenter appliance.

VMware ESXi Server Build Numbers

vmware

I’ve been doing a fair bit of VMware patching recently so thought it would be useful to highlight the current and past versions of ESXi and how to check which version you are running. The latest version is 6.5 released 15th November, 2016. Since then there have been a few patches.

Below is a snapshot of the current versions as of 22 March 2017.

As with any new software test in a development environment first before upgrading to a new major version, let others lead the way on the bleeding edge and wait for Patch 1 to be released.

Version 6.5
Version 6.0
Version 5.5
Version 5.1
Version 5.0 Continue reading

How to check the last time an ESXi host booted

VMware

I was investigating some VM issues recently, and needed to find out when an ESXi host last rebooted to see if I could correlate logs with events to discover the source of the issue.

There are a few of easy ways to find out the last time an ESXi host booted, there are probably more, but these should be enough for a quick check. Continue reading

How to resolve VMware Workstation “The network bridge on device ‘VMnet0’ is not running”

VMware

So I turned on my test SBS 2011 server today to test out the latest Exchange Update Rollup and was greeted by an VM  that was hanging on startup. Looking into the issue more closely the virtual network adapter was disconnected and when I tried to select ‘connect’ I received the following error message:

The network bridge on device ‘VMnet0’ is not running. The virtual machine will not be able to communicate with the host or with other machines on your network. Failed to connect virtual device ‘Ethernet0’.

the network bridge on device vmnet0 is not running failed to connect to virtual device ethernet0 Continue reading

How to resolve VMware ESXi 6.0 only detects first NIC when nested in VMware Workstation

VMware

I’m updating my certifiactions at the moment and to help with my VCP I’m in the process of building a vSphere 6 home lab. I’m using VMware workstation and within it I’m setting up two ESXi 6.0 hosts, a vCSA and a single DC. Each ESXi host has ten NICs with will be distributed and teamed onto five different networks, Management, Storage, vMotion, and two sudo VLANs for VMs. The problem is only the first Network Adpater which was bridged has been detected correctly.

At first i didn’t notice it, as in VM Workstation everything looks ok. The Network Adapters were added in VMware Workstation with out an issue, and assigned to the correct custom virtial networks. Continue reading

How to convert a Hyper-V VHDX to VMDK for VMware Workstation

Starwind Software

In this post we’ll look at how to convert a Hyper-V virtual machine using the VHDX format virtual disk to a VMware Workstation virtual machine using the vmdk format virtual disk.

Until Windows 8 I’ve used VMware Workstation for testing, but with the advent of  Windows 8 and the built in Hyper-V I decided to give it a try and have been using it quite happily ever since. In the near future though I’m going to be looking at some vSphere testing, and from memory recall that you can nest it within VMware Workstation, so I thought I would give the latest version a go.

The only problem is I don’t want to rebuild my current test environments so I need some way of converting the VHDX that Hyper-V uses to vmdk that VMware Workstation uses.

My first thought was VMware converter, but that doesn’t support VHDX, so looking around on the Internet I cam across a nifty bit of FREE software from StarWind Software- StarWind V2V Converter.

You have to register to download the product, but once you have and installed it below are the steps I took to convert a UEFI Boot, Gen 2, 2012 R2, Hyper-V VM using VHDX to vmdk for VMware Workstation.

vCenter Server stopped, event id 1827, 1105

vmware

In recent months I’ve been mainly focused on Hyper-V installations, but I’ve had an interesting VMware week this week. After 7 years of using ESX and then ESXi in production i experienced my first Purple Screen of Death which although inconvenient at the time i don’t think is too bad going!

Then later in the week and the subject of this post vCenter stopped running on one of our oldest installations.
