VMware: The OVF Descriptor is Not Available
KB ID 0001483 Problem I’ve seen this a couple of times now, and each time I’ve (wrongly) assumed that the OVA/OVF file I’ve downloaded is either corrupt, or it has some sort of problem. Failed to deploy OVF package. Cause: A general system error occurred: Transfer failed: The OVF descriptor is not available. Solution Redeploy the OVF file, but this time instead of selecting the Cluster, select A SPECIFIC HOST to...
VMware Cannot Remove / Unmount an NFS Store
KB ID 0001479 Problem After I had a datastore failure I needed to ‘unmount’ a datastore in my VMware 6.5 environment. But when I attempted to do so I got; The “Remote Datastore” operation failed for the entity with the following error message. The resource “Datastore-Name” is in use. Solution In use by what?

VMware vSphere Hot Add and Hot Plug
KB ID 0000527 Problem I was trying to hot add some memory to a VM the other day, and found the option grayed out. Normally I’d just down the VM, add the memory, then bring it back up. But it was a production server and I was pretty sure the OS supported it. A quick Google search told me why it was grayed out, but it also transpired there was little to no information on what version of Windows hot add and hot plug would work...

Solution While logged into vCenter > Home > Policies and Profiles > VM Storage Policies > Create VM...
VMware vSphere Virtual Machine Encryption
KB ID 0001470 Problem Other that learn this for an exam I’ve never had to deploy this in anger. So when I heard we had a customer at work who wanted to take a look at it I was quite keen to take a look. To encrypt a VM you need to have an additional KMS (Key Management server) which VMware do not provide. They do provide a list, so theres no point me posting a list that will be out of date in a couple of weeks. Our client...
VMware Cannot Upload Large ISO File?
KB ID 0001463 Problem I was trying to upload a windows 10 use file to my vSphere environment, and it was continually failing; I tried multiple datastore on multiple hosts, same result. It wasn’t until I connected directly to one of the hosts to try that I saw a more descriptive Error; Brilliant Thanks Microsoft! Their website says; You may notice that even IE11 is limited to 4gb uploads, but that’s not a significant...
vSphere: Downgrading Guest ‘Hardware Version’
KB ID 0001458 Problem I always assumed this was either not possible, (without using VMware converter,) or at least very difficult. I downgraded one of my test ESX boxes from 6.5 to 5.5 this week, and needed to lower the hardware versions on some of my VMs accordingly. Solution Connect to the host ESX server via SSH, then navigate to the VMFS volumes; cd /vmfs/volumes Change directory so you are in the right ‘datastore’,...
