for what you says, the path of Volume Group should be

but when I use it get the error
--------------------
Path required for Logical Volume "fedora_localhost"
Please provide a volume group name.

to resize the volume group I use the command:
lvm lvreduce -L650 G /dev/fedora_localhost
You are confusing "volume group" and "logical volume". Volume groups
contain logical volumes.
lvreduce means to reduce a logical volume
vgreduce means to reduce a volume group
You cannot arbitrarily change the size of a VOLUME GROUP from e.g. 1000G
to 500G.
When using the lv... and vg... commands it is not necessary to use the
full path, only VG name and LV name (/dev/ not required). When using
resize2fs you must use the entire path including /dev/.
In your case the logical volumes in fedora_localhost are root,home, and
swap. You would use lvreduce to reduce the size of one of them.
e.g. lvreduce -L650G fedora_localhost/root. NEVER reduce a logical
volume until you have already resized it.
