Unable to storage vMotion vCLS VMs – A specified parameter was not correct. StoragePlacementSpec.vm
I was completing tasks to delete datastores and consolidate storage capacity but hit a blocker when attempting to put a datastore in to Maintenance Mode. The datastore didn't go in to Maintenance Mode and I was left with a few vSphere Cluster Services (vCLS) VM's unable to move. If you're unsure what these vCLS VM's … Continue reading Unable to storage vMotion vCLS VMs – A specified parameter was not correct. StoragePlacementSpec.vm
vMotion failing with “The VM failed to resume on the destination during early power on. The source detected that the destination failed to resume.”
VMware KB 59665 advises to reboot the VM to clear any locks but I found this wasn't required.

Remember to move the VM Configuration file … Continue reading vMotion failing with “The VM failed to resume on the destination during early power on.

Hide VMs in the Hosts and Clusters view in the vSphere Client
This is a great setting to change for Administrators that spend most of their time in the Host and Clusters view managing hosts rather than the VMs. It's a feature that was easy to change and quite well known in the old fat client but seems to get forgot about in the new HTML5 vSphere … Continue reading Hide VMs in the Hosts and Clusters view in the vSphere Client
Workaround for the vCenter 7.0 ‘Failure to deploy OVF package’ bug when deploying VMs from a Content Library with a Proxy enabled
I was unable to deploy VMs from my Content Library after upgrading vCenter to 7.0. I have one Publisher Library and multiple other Content Libraries subscribed to it but I couldn't deploy from any of them. The VM deployment would begin and the percentage would increase but fail midway through with the following error: Failed … Continue reading Workaround for the vCenter 7.0 ‘Failure to deploy OVF package’ bug when deploying VMs from a Content Library with a Proxy enabled
