I recently ran into a problem were virtual machines running Windows 8 and Server 2012 don’t ever come back from a reboot, but rather get stuck on the Windows boot splash screen. The only work around to get the machine to boot is to manually power it off and then power it on again.
Good news is, there is a solution to this crazy weirdness; and it is documented below…
Recently I needed to find if any virtual machines had been deployed or cloned on a particular day (in order to troubleshoot a storage issue).
The Tasks & Events view in the VI client only shows the last few days of events, so if you need to get events from an older date the only way is through PowerCLI.
Here is how to do get a list of events from vCenter Server using PowerCLI…
Recently I upgraded my home test lab with a new ESXi white box host. This host is a custom built PC that runs an Asus Gryphon Z97 micro-ATX motherboard. A few people have asked me how I got ESXi 5.5 running on the Asus Gryphon Z97, so I thought I would post up how I did it here….
You have a VM that is part of a port group on a distributed switch, however the network adapter is disconnected. When attempting to enable the network adapter for the VM by ticking Connected in Edit Settings, it fails and you get the error message of:
Invalid Configuration for device '0'.
I had the same problem and here is how I fixed it…
Once I built my ESXi 5.5 hosts in my test lab and added them to my vCenter environment, they both had a yellow warning prompt stating: “No coredump target has been configured. Host core dumps cannot be saved”
The good news is I was able to fix this, so I thought to document the solution in case anyone else has the same issue. All the details are below…
I wanted to upgrade the memory on my vSphere 5.1 vCenter server to 16GB and I didn’t have hot-add enabled. I powered off the VM, connected directly to the host and re-configured the VM as required and then clicked OK.
At this point, I got an error saying “Access to resource settings on the host is restricted to the server that is managing it: X.X.X.X”.
The host things it is still being managed by vCenter so it won’t let me edit the VM. vCenter server is powered off so that I can edit the VM (as hot-add is not enabled the VM has to be powered off to change the memory amount).
This is how to fix this issue…..
In October 2014, I wrote an article about what I was looking to build in my new home test lab. Since then I have been hard at work setting it up and I have made a number of design changes since then. Here is an update on my progress…
