In virt-manager open the storage view and manually refresh.  It should then
show the correct size.  Storage view I believe is under Edit -> Connection

Also you may want look at using the virt-resize command to combine the
steps of qemu-img and the LVM commands.  It can resize the virtual disk and
the guest's logical volumes in a single command.
