Sometimes it happen that the *getty in the guest is actually ready, but you just don't get the prompt. To check that, the easiest way is to just hit enter a few times to see if there is any echo/prompt showing up. > > In 7.3 guest I have VirtIO serial console enabled and this situation > > [root@c7service ~]# cat /proc/cmdline > BOOT_IMAGE=/vmlinuz-3.10.0-514.6.1.el7.x86_64 root=/dev/mapper/cl-root > ro rd.lvm.lv <http://rd.lvm.lv>=cl/root rd.lvm.lv > <http://rd.lvm.lv>=cl/swap rhgb quiet console=ttyS0 > [root@c7service ~]# > > [root@c7service ~]# ps -ef|grep agetty > root 718 1 0 11:15 ttyS0 00:00:00 /sbin/agetty > --keep-baud 115200 38400 9600 ttyS0 vt220 > root 1760 1541 0 11:29 pts/0 00:00:00 grep --color=auto agetty > [root@c7service ~]# > > So it seems ok.

It means you haven't given the "-t" ssh options. Please retry with: ssh -t -i .ssh/id_dsa.pub ovirt-vmconsole@ovmgr1 -p 2222 connect --vm-name c7service > What is "client" in the error message, my Fedora 25..?
