Thanks ... pool-refresh seems to do the trick and is what I was looking for.
Comment:
Doing "virsh -h" lists a lot more capabilities than are list in the virsh man
page. Furthermore, looking at available documentation on http://libvirt.org/,
I do not see any info there about these new capabilities either.
Other than the source code, can you point me to some documentation so I do not
keep having problems/questions which are already addressed by the code?
Googling around, I found http://libvirt.org/storage.html ... however, this is
NOT listed on the main page of the website http://libvirt.org/ and it still
does not describe the capabilities in virsh.
More than likely, this is a "work-in=progress" and documentation has not been
created for the latest capabilities yet.
