Description

There was another issue, which hit if SSH is running on a non-standard port eg, If SSH is on port 9000 virt-viewer -c qemu+ssh://root@lettuce:9000/system rhel6x86_64 Should result in two ssh connections being opened ssh -p 9000 -l root lettuce nc -U /var/run/libvirt/libvirt-sock-ro ssh -p 9000 -l root lettuce nc localhost 5900 But we missed out the '-p 9000' part of the second connection. This is also fixed in this BZ this bug can reproduce with virt-viewer-0.4.1-1.el6
verify with virt-viewer-0.4.1-3.el6:
step:
for vnc:
default port:22
#virt-viewer -c qemu+ssh://root.4.218/system test-yp --debug
output:
.....
** (virt-viewer:1831): DEBUG: Guest (null) has a vnc display
** (virt-viewer:1831): DEBUG: Guest graphics address is localhost:5900
** (virt-viewer:1831): DEBUG: Set connect info: 10.66.4.218,localhost,5900,ssh,(null),root,0
** (virt-viewer:1831): DEBUG: Opening indirect TCP connection to display at localhost:5900
** (virt-viewer:1831): DEBUG: Setting up SSH tunnel via root.4.218
.....
the guest can open w/o error.
change ssh port to 9000
#virt--viewer -c qemu+ssh://root.6.166:9000/system XXdemo --debug
.....
** (virt-viewer:4118): DEBUG: Guest (null) has a vnc display

** (virt-viewer:4118): DEBUG: Setting up SSH tunnel via root.6.166:9000
.....
the guest can open w/o error.
test with spice:
default port:22
#virt-viewer -c qemu+ssh://root.6.166/system winxp --debug
.....

** (virt-viewer:5735): DEBUG: Opening indirect TCP connection to display at 0.0.0.0:5900
** (virt-viewer:5735): DEBUG: Setting up SSH tunnel via root.6.166
.....
the guest can open w/o error.
ssh port:9000
