As has been pointed out, SELinux may prevent that from working with a 
simple symlink.  You have two options that will work:

1: Create a symlink and set the context of the link destination to the 
same context used for /var/lib/libvirt/images.  Use semanage to make the 
changes permanent, or else a restorecon might break the system:

2: Use a "bind" mount instead of a symlink.  Enter a line in /etc/fstab 
like this one:
   /bigger/fs	/var/lib/libvirt/images	none	bind	0 0
Then, mount /var/lib/libvirt/images and "restorecon -r -v 
/var/lib/libvirt/images"
