oVirt never uses passowrd for ssh communication to the root user of remote hosts.Check if passwordless ssh is configured. You can set a host in maintenance and re add the host.

oVirt runs as user vdsm@ovirt so security settings prevent other users including root from seeing it by default. root should be able to see it as in readonly virsh -r list You can either run the command on hypervisor like this alias alias virsh='virsh -c qemu:///system?authfile=/etc/ovirt-hosted-engine/virsh_auth.conf' or you can lookup the default vdsm@ovirt password online and then login with those credentials and see it. #root account on 'oVirt node' hosts can't connect to ovirt's details #login as vdsm@ovirt instead # # virsh -c qemu:///system # user: vdsm@ovirt # pass: shibboleth On Mon, Jun 21, 2021 at 1:20 PM tommy <sz_cuitao@163.com> wrote:
