Vcenter exists as a virtual machine. However, after esxi is restarted, it cannot be logged into the vcenter for half a day. Therefore, you can directly log on to esxi and find that the vcenter virtual machine is not started.-_-|
The cause of the problem was found. The Automatic startup feature of the VM was not enabled.
To enable the Virtual Machine startup/Shutdown option:
- Log in to the host directly using the vsphere client.
- ClickConfigurationTab.
- ClickVirtual Machine startup/Shutdown.
- ClickPropertiesLink.
- Change the settingEnabled.
