Hello
i'm trying to connect with a remote libvirt.
The option I selected was tcp because it's a development environment and a
secure and isolated network,
I've configured
listen_tcp = 1
tcp_port = "16509"
in libvirtd.conf at the destition.
I've tried to connect to host "santacruz" from a remote host
"aoniken" and
locally but pn both cases I've got:
REMOTE
marcela@aoniken:~$ virsh -c qemu+tcp://santacruz:16509 list
error: unable to connect to libvirtd at 'santacruz': Connection refused
error: failed to connect to the hypervisor
LOCALLY
radic@santacruz:/etc/libvirt$ virsh -c qemu+tcp://santacruz:16509 list
error: unable to connect to libvirtd at 'santacruz': Connection refused
error: failed to connect to the hypervisor
I've try to use ssh but i've got an error two on both cases.
REMOTE (SSH)
marcela@aoniken:~$ virsh -c qemu+ssh://radic@santacruz list
radic@santacruz's password:
error: internal error no QEMU URI path given, try qemu:///system
error: failed to connect to the hypervisor
marcela@aoniken:~$
radic@santacruz:/etc/libvirt$ virsh -c qemu+ssh://radic@santacruz list
radic@santacruz's password:
error: internal error no QEMU URI path given, try qemu:///system
error: failed to connect to the hypervisor
Can you help me?
Thank you

?Hi,
donc forget to start libvirtd with the "-l" (listen) argument. Generally,
it's in your /etc/init.d/libvirtd script.

Arnaud

Hey Marcela,
You didn't mention which Linux distro you're using? That'll help us know
which config files you'd have
and so forth. :)
Some thoughts:
+ Guessing you have root access on the "santacruz" box, so try this first with
ssh just to see if it works:
$ virsh -c qemu+ssh://root@santacruz/system list
+ If that works, and you're ok with using ssh, then you can set up your
"radic" user for access to libvirt:
http://wiki.libvirt.org/page/SSHSetup
(the libvirt.org server seems to be offline atm :( )
When that's set up, you should then be able to connect with:
$ virsh -c qemu+ssh://radic@santacruz/system list
+ If you really want to enable the tcp connection type, rather than ssh, then you might
want to turn off
all authentication for it. On a RHELRHEL/Fedora/CentOS type of system this is done by
setting:
auth_tcp = "none"
In your /etc/libvirt/libvirtd.conf file, then restarting the libvirt daemon. Still,
that will only help once
you get the tcp connection listening anyway. :)
Um, that's the best I can think of for the moment. Hopefully it helps? :)

series of usual "stupid" questions:
1] have you restarted libvirt at santacruz?
2] is libvirt listening at 16509 at santacruz?
# netstat -nlp | grep 16509 ;
3] isn't there firewall in your path?
4] please, try:
% virsh -c qemu+ssh://santacruz/system list ;
If you need to specify SSH port, then:
% virsh -c qemu+ssh://santacruz:1234/system list ;
I don't use TCP, so I can't help you with this one. May be it's the very
same problem for TCP and SSH, because your commands didn't work for me
either.
Regards,
Z.
