In the vSphere 5.5 web client, which is now where you have to go to add a new HDD when you upgrade the VM version to 10...when I add one, I don't get the option to change the disk provisioning. Any ideas as to why? This is from a powered off VM, with no snapshots:
Ah...yes, it is a NFS datastore, and as far as I know, HW acceleration is not enabled. A quick search showed me that you have the NAS plugin installed to enable it...and we don't have that. I guess that will be the next step. Thanks!
