[ovirt-users] Bug: Spice port changed!!!!!

[David Jaša]

Hi Paul,

This behaviour is by design. It is a bad idea to override it. A good
approach to your problem would be to write a launcher script that would:
1) connect to the REST API
2) get the VM connection details
3) get new VM ticket
4) write this info down to a temporary .vv file [3]
5) launch remote-viewer

Some info how to use REST API is described here [1] and .vv file format
is documented in virt-viewer sources [2]. Please note that [1] is a bit
outdated:
  * you can use HTTP header "filter: true" to be able to log in as non-admin
  * you only have to use password login once when you use
    "prefer: persistent-auth" HTTP header and you send the cookie you got
    in a response to first request.
In the future, the steps 2-4 will become a one step of getting a
ready-to-use .vv file from the API [3] but we aren't there yet.

However, if you _really_ want to stick with static port assignments, do
the following:
1) designate the port range so that it doesn't collide with other ranges
in use (e.g. RHEV uses 5900-6023, so 5800-5899 could be safe)
2) add a custom VM properties to the engine for setting of port and
tls-port
3) add a vdsm hook to before_vm_start directory on each host that will
add "port" and "tlsPort" parameters to the graphics element of libvirt
domain xml


Best regards,

David
