vSphere Upgrade VMware Tools Suppress Reboot
KB ID 0001760 Problem If you want to Upgrade VMware Tools and Suppress the Reboot, (because rebooting production servers is always a touchy subject), But putting ‘maintenance windows’ and ‘CAB procedures’ to one side.

Can you Backup the Free Version of ESX 7?
KB ID 0001757 Problem ‘Backup the Free Version of ESX?’ This was asked on Experts Exchange this week, I responded with the usual answer of “No the VAPI is not exposed in the free version, so it cannot be backed up by a third party backup application.” The poster responded with, “That’s what I thought, but I’ve got a Technical Consultant here who says it can be done with version 7” This...

OVA / OVF Deployment Gets Stuck ‘Validating’
KB ID 0001664 Problem I had this problem (on sphere 6.7) the other day when trying to deploy some OVA files on my test network. Solution Well as stated elsewhere I tried reconnecting to my vCenter using its FQDN, this didn’t solve the problem, using Flash or HTML5 didn’t cure the problem either.

VMware: Cannot Resize a VMs Hard Drive?
KB ID 0001704 Problem One of the lads in support messaged me this week, he needed to raise the size of the hard drive on a VM, and the option was greyed out (not available).
