Defining Azure governance so that your subscriptions, management groups is correctly built out and deployed is critical. Even with the best planning sometimes it is still necessary to move resources to a new subscription. While Learn documents how this can be done, it does not work for all scenarios.

Create Azure Az VM Using Existing UnManaged VHD

Posted on 7th May 2021 by Rhoderick Milne [MSFT]

The days change, but sometimes the issues stay the same. This is a redux of an existing post where there was an issue back in 2016 when I was not able to easily re-create a VM in a different Availability Set. As you can see in Create Azure RM VM Using Existing VHD – 250 Hello (rmilne.ca) PowerShell was used to re-create the VM as it allowed all of the resources to be specified.

The original VM was… Read the rest “Create Azure Az VM Using Existing UnManaged VHD”

Hyper-V VM Import–Know Before You Go

Posted on 27th March 2018 by Rhoderick Milne [MSFT]

Importing VMs from one host to another can run into issues due differences in the configuration of the hosts. A common issue is that a virtual switch does not exist on the new Hyper-V host. While it is possible to attempt the import, and then deal with the fallout afterwards, wouldn't it be great to know about such issues before actually starting the import?

That is where the Compare-VM cmdlet co… Read the rest “Hyper-V VM Import–Know Before You Go”

Quick Tip–Adding Same ISO DVD Image To All Hyper-V Lab VMs

Posted on 18th August 2017 by Rhoderick Milne [MSFT]

When building out a lab, you might need to attach the same ISO to multiple VMs. In this case I was installing multiple Exchange 2016 severs, and wanted to easily add the same ISO file to each of the VMs.

This was on my Windows 10 laptop which makes quick work of the task since we can use PowerShell.

The VMs to target all have the same naming convention. The VMs for the Exchange 2016 lab start with… Read the rest “Quick Tip–Adding Same ISO DVD Image To All Hyper-V Lab VMs”

Last week after showing a client some of new features in Windows 10, they went off and upgraded a laptop to the preview from Windows 8.1. Initially all seemed to go well. That is until they tried to start up VMs on their SSD drive. At that point Mr Sad & Grumpy came to visit.

They were getting errors such as:

In the screen shot below, there should be 10 VMs displayed which have the prefix of “HA”.

VMware Issues With Exchange DAG

Posted on 21st July 2014 by Rhoderick Milne [MSFT]

When resolving issues with on-premises Exchange sometimes the issue may be directly within Exchange, other times the root cause may lie outside Exchange. Depending upon the exact nature of the case we may have to investigate network switches, load balancers or storage. When Exchange is virtualized then the hypervisor and it’s configuration also may require attention.

This was the case with a rece… Read the rest “VMware Issues With Exchange DAG”
