Fedora xen - Nov 2006 - RE: virt-manager gives "The console is currently unavailable" in FC6

When first setting up FC6 I had an issue where I could start an FC6 Xen
guest install but couldn''t connect with VNC.

I don''t know if it''s the same (I can''t remember the
exact messages I was
getting), but it ended up being that "localhost" wouldn''t
resolve to an
IPv4 address. This was due to a nasty combination of anaconda putting IPv4
and v6 entries in /etc/hosts and system-config-network trimming the
"extra" v4 entry when run.

Anyway I''d suggest:
- Check that you can ping localhost
- Check there''s a localhost entry in /etc/hosts associated with
127.0.0.1
(and not with ::1)
- Run "netstat -antp" to see what ports programs are listening on

Ahhh, that would certainly make sense - virt-manager explicitly connects
to ''localhost'' when opening the VNC connection. Since the VNC
server
doesn''t support IPv6, I think it''d be fairly safe for me to
switch
virt-manager to explicitly use ''127.0.0.1''  which would
eliminate this
particularly /etc/hosts issue.

Thanks for the info about the issue.

Dan.

YES.
You are right.
Each time I had the intuition it was a problem with VNC connection.
Effectively, after initialising localhost in /etc/hosts everrything works
right again.
The good question is now why it comes in this situation ? I never modified
this localhost.
Is this an issue with system-config-network or another installation I made ?

In any case, really THANKS for your help !
