如何在vijava中获得vm权限

Question

I'm trying to get permissions of virtual machine using vijava like this:

ManagedEntity me = new
InventoryNavigator(rootFolder).searchManagedEntity("VirtualMachine", vmName);
                VirtualMachine vm = (VirtualMachine) me;
for (Permission permission : vm.getPermission()) {
                System.out.println(permission.getPrincipal());
}

With this I get permissions applied only for This vm.

How can I get total permissions on virtual machine including inherited?

Answer 1

I'm not sure if that's possible, because each list of permissions is associated with a specific entity (ie VirtualMachine, HostSystem, etc..).

The way I'd do this is I'd get the underlying entities for the virtual machine and get their permissions as well. For example, since you have the VirtualMachine object, get the underlying HostSystem and retrieve it's permissions, and so on.

ManagedEntity me = new
InventoryNavigator(rootFolder).searchManagedEntity("VirtualMachine", vmName);
                VirtualMachine vm = (VirtualMachine) me;

// Assuming that you have a ServiceInstance object si.
HostSystem host = (HostSystem)MorUtil.createExactManagedEntity(si
                        .getServerConnection(),vm.getRuntime().host);
Permission[] hostPermissions = host.getPermission();

I hope that helps.

To get all inherited permissions you should get all parents permissions like this:

  while (me.getParent() != null) {
        me = me.getParent();
        Permission[] permissions = me.getPermission();
        if (permissions != null) {
            for (Permission p : permissions) {
                // do stuff....
            }
        }
    }
