vCenter Converter Standalone P2V 移轉後
在Vmware Host中開機出現Cannot Start a VM - A general system error occurred: Connection refused
解決方式要在vCenter主機中，輸入下列命令：
#shell.set --enabled true
#service-control --status vmware-vpx-workflow
(this command confirmed the service was stopped)
#service-control --start vmware-vpx-workflow
Once running, I was able to start VMs again from vCenter.
Not sure why this was so hard to find in a web search but hopefully the search engines will pick up this blog post and save people some time!
