Explanation:
NSX Manager is the central management component of VMware NSX-T Data Center, which provides the management, configuration, and monitoring functions for NSX-T Data Center. In a KVM environment, NSX Manager runs as a virtual machine.
To start the NSX Manager virtual machine in the KVM environment, the virsh poweron command is used. This command is used to power on a domain (i.e., virtual machine) that is currently in a shutdown state. The syntax of the command is:
virsh poweron <domain-name>
where <domain-name> is the name of the virtual machine to be powered on.
Option A, virsh start <NSX-Manager-Name>, is incorrect because the start command is used to start a domain that is in the defined but inactive state. It is not used to power on a domain that is currently in a shutdown state.
Option C, virsh poweron <nsx-manager-ID>, is also incorrect because the <nsx-manager-ID> refers to the ID of the domain, which is an internal ID used by libvirt (the virtualization API used by KVM) to identify domains. However, it is more convenient to use the domain name instead of the ID.
Option D, virsh start <NSX-Manager-ID>, is also incorrect for the same reason as option A. The start command is used to start a domain that is in the defined but inactive state, and the <NSX-Manager-ID> is not the most convenient way to identify the domain.
