virsh no connect to any host

C

cahimira

I have a problem with "virsh" in FreeBSD 9.0 and 9.1 (all ports updated). When I try to connect to a remote host via SSH, I get this error:

$ virsh -c [url=qemu+ssh://root@]qemu+ssh://root@[/url][IP-ADDRESS]:[PORT]/system
Code: 
error: failed to connect to the hypervisor
error: End of file while reading data: : Input/output error
The hypervisor daemon (libvirtd) and SSH daemon are running on the remote host. I can connect from Linux without any problems.

Suggestions?

Thank you.
 
Do the logs on the target system mention anything?

You can run sshd with more logging by increasing LogLevel in /etc/ssh/sshd_config.
