accoding to this https://docs.openstack.org/admin-guide/telemetry-measurements.html (link), There seems to be no difference.

I want to know Avail space.

# df -h /
Filesystem      Size  Used Avail Use% Mounted on
/dev/sda1       407G   18G  369G   5% /

how can i get?

All aforementioned meters are different and described in NOTE column at page U've sent. Also I doubt that libvirt is providing info about free space inside the guest.

There is no easy solution though if guest vms have floating ips U can use SNMP based meters
