vSphere 6.7 quick boot is new feature which is integrated with update manager. When we performing patching activities with earlier versions of vSphere most of the time we need to reboot the ESX hosts. This is very painful because normayy it will take more than 5 minutes to reboot hardware server. Also sometimes we may need to login using ILO\BMC\IDRAC and check the boot status.
