[ovirt-devel] Re: My web console(remote viewer) cannot connect to other cluster's vm.

Thanks for your replay. I have tried using IP instead of hostname, but it still not work. I want choose spice instead of vnc to have a try. But the button can not be chosen, what should I do to activate the spiece ?

This seems correct, basically, assuming your client correctly resolves ohost1.tltd.com. Please check/share relevant logs. Try e.g. to run remote-viewer manually with --debug and --verbose. Also check with a sniffer (tcpdump/wireshark) that the client indeed tries to connect to the correct host. If all looks fine, check with a sniffer on the host that the connection is accepted, and relevant logs - mainly qemu (in /var/log/libvirt/qemu), although I am not sure it logs connections by default. Good luck and best regards, -- Didi _______________________________________________ Devel mailing list -- devel(a)ovirt.org To unsubscribe send an email to devel-leave(a)ovirt.org Privacy Statement: https://www.ovirt.org/privacy-policy.html oVirt Code of Conduct: https://www.ovirt.org/community/about/community-guidelines/ List Archives: https://lists.ovirt.org/archives/list/devel@ovirt.org/message/UAJVR2EL FFEDPEIQJ7BKWQQ7GOEFEFC5/
