[virt-tools-list] virt-tools-list Digest, Vol 108, Issue 3

Mon Jun 4 23:21:36 UTC 2018

As I continue troubleshooting, I regenerated keys = no joy.
What I did find, if I use the command "ssh -X root at server
virt-manager" from a terminal, it asks for the server's root password,
the virt-manager gui appears and populates, I open a VM and all works
great! Doesn't ask for any other passwords; The VM console works.

When I open the Virtual Machine Manager from the gui, and open the
properties of the connection I see "qemu+ssh://root@server/system"
There is no -X in this command.
I have deleted the connection, and created a new one, selected SSH,
and there doesn't seem to be any way to append the -X to the default
"qemu+ssh://root@server/system".

I have checked the config files in the /etc/libvirt directory, but
have not been able to find how to change the default Libvirt URI to
include the -X

ps. you are correct, testing your suggestion about spice, I made the
connection to the remote vm, (from the virt-manager gui) I entered my
password 8 times, and the console appeared... had to type the PW every
time, it didn't allow copy/paste (so much for 16 char passwords!!!)

So cool, but not, it's just cool starting to understand how this
works, and even COOLer having individuals to ask for help.... Thank
you SO BIG.
