[libvirt] Connecting with a remote libvirt
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.

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? :) Regards and best wishes, Justin Clift
Thank you very much. It's working noow. Regard. Marcela 2011/2/1 Justin Clift <jclift@redhat.com>

[...] 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.
