The man page says: "(Re)-Connect to the hypervisor. When the shell is
first started, this is automatically run with the URI parameter
requested by the "-c" option on the command line." However, if you run:
virsh -c 'test://default' 'connect; uri'
the output will not be 'test://default'. That's because the
'connect'
command does not care about any virsh-only related settings and if it is
run without parameters, it connects with @uri == NULL. Not only that
doesn't comply to what the man page describes, but it also doesn't make
sense. It also means you aren't able to reconnect to whatever you are
connected currently.
So let's fix that in both virsh and virt-admin add a test case for it.
