This is very odd. So I patched up my fresh install of 5.0 with the recent roll-up package. After mounting the datastore on the SAN, I went to software => advanced => Virtual machine startup/shutdown. I clicked on the box to allow VMs to start/stop with the host (like I've always done before.) Moved 'em all up to the Automatic Startup section. I had to shutdown to finish shuffling some disks around on the SAN box. I was dismayed to see the power off happen almost instantly. When I rebooted, I logged into the vsphere client as soon as I was allowed too, and saw.... Nothing. None of the VMs were starting. I verified that they were all still in the right section and the startup box was still checked. Any ideas what I should be looking at? Thanks...
