[libvirt-users] Issues Connecting to Remote Host Through SSH
Hello, I've been unable to connect to a remote host from within my network using the following argument. virsh/virt-manager -c qemu+ssh://user@host:port/system I've tried libssh & libssh2 as well. Using ssh just prompts me for the host password indefinitely. When using libssh2 the connection is rejected. The host computer is using a custom ssh port which I've added to the above argument. Neither box has an enabled root user. Remote box $ cat /etc/debian_version 9.3 $ ssh -V OpenSSH_7.4p1 Debian-10+deb9u2, OpenSSL 1.0.2l 25 May 2017 $ virsh --version 3.0.0 Host box $ cat /etc/centos-release CentOS Linux release 7.4.1708 (Core) $ ssh -V OpenSSH_7.4p1, OpenSSL 1.0.2k-fips 26 Jan 2017 $ virsh --version 3.2.0 Any help is greatly appreciated.

When using the 'ssh://' scheme, libvirt expects that you have configured an SSH agent and publickeys to provide seemlessly non-interactive auth. virsh opens a single SSH connection, but virt-manager will open multiple connections if you have a domain VNC/SPICE console open. With libssh/libss2 we ought to be able to prompt for the password interactively IIUC.

There was an issue with virsh corrected by libvirt 3.4.0 where virsh would continue prompting for password as a result of polkit and pkttyagent interactions See: https://bugzilla.redhat.com/show_bug.cgi?id=1374126 or the upstream commit: https://libvirt.org/git/?p=libvirt.git;a=commit;h=2453501fc8 Perhaps that's what you're bumping into at least w/r/t the indefinite password prompting.

The host computer is using a custom ssh port which I've added to the above argument. Neither box has an enabled root user.
Remote box
$ cat /etc/debian_version 9.3
$ ssh -V OpenSSH_7.4p1 Debian-10+deb9u2, OpenSSL 1.0.2l 25 May 2017
$ virsh --version 3.0.0
Host box
$ cat /etc/centos-release CentOS Linux release 7.4.1708 (Core)
$ ssh -V OpenSSH_7.4p1, OpenSSL 1.0.2k-fips 26 Jan 2017
$ virsh --version 3.2.0
Any help is greatly appreciated.
