RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

Fixed In Version: virt-viewer-2.0-12.el6

Doc Text:
The virt-viewer tool can now report the SPICE client version being used to connect to a console. This allows a minimum SPICE client version to be set using the engine-config tool, and older SPICE clients to be blocked from connecting to virtual machine graphical consoles.

Comment 2 mxie@redhat.com 2016-01-07 03:37:33 UTC 
Hi Jonathon,

Could you help to see below problem

Try to verify this bug with builds:
virt-viewer-2.0-11.el6.x86_64
spice-gtk-0.26-7.el6.x86_64
libvirt-0.10.2-55.el6.x86_64

Steps to Reproduce:
1. Check remote-viewer manual page:
# man remote-viewer
...
CONNECTION FILE
...
       "versions" (osid:version list)
           This is a list of osid:version couples separated by ';'. osid is an arbitrary string, version is a version number in the same
           format as in the 'version' field. A given couple indicates that remote-viewer builds matching the given 'osid' (fedora22,
           debian7, ...) must be at least version 'version'. For consistency, it's recommended to use libosinfo OS shortids as the osid.

       "newer-version-url" (string)
           If specified, this field is an URL which will be displayed to the user when a version check fails.
...

Result: 
'versions' and 'newer-version-url' 2 options already added.

2. Check "--with-osid" outputs:
# remote-viewer -V
remote-viewer version 2.0 


3.Prepare a running guest and configure console.vv file.

# cat console.vv
[virt-viewer]
type=spice
host=127.0.0.1
port=5905
fullscreen=0
versions=3.0---------------> or change to version=rhel6:3.0

4. Use remote-viewer to connect vm.
# remote-viewer console.vv

Result: Can connect to guest successfully.

So virt-viewer-2.0-11.el6.x86_64 doesn't support for minimum version check to rhev spice-client yet

Hi mxie,

> 2. Check "--with-osid" outputs:
> # remote-viewer -V
> remote-viewer version 2.0

Note that there is no "OS ID".

Please try:
version=3.0  # note -- "version" without 's'

For "versions" to work the package must be built with OS ID (and
it probably should).

> 
> 4. Use remote-viewer to connect vm.
> # remote-viewer console.vv

Please run this again and see what happens.

yes, sorry for this mistake. I forgot to commit that part of the change. I will make a new build soon.
Comment 5 Jonathon Jongsma 2016-01-07 20:17:39 UTC 
try again with -12. But note Uri's comment above. If you want to specify different minimum versions for different platforms, use the key "versions" (with the 's'), but if you want to provide a fallback minimum version number, use "version" (with no 's').

Thanks for Jonathon and Uri's reply and reminder

Try to verify this bug with builds:
virt-viewer-2.0-12.el6.x86_64

Steps:
1. Check remote-viewer manual page:
# man remote-viewer
...
CONNECTION FILE
...
       "versions" (osid:version list)
           This is a list of osid:version couples separated by ';'. osid is an arbitrary string, version is a version number in the same
           format as in the 'version' field. A given couple indicates that remote-viewer builds matching the given 'osid' (fedora22,
           debian7, ...) must be at least version 'version'. For consistency, it's recommended to use libosinfo OS shortids as the osid.

       "newer-version-url" (string)
           If specified, this field is an URL which will be displayed to the user when a version check fails.
...

Result: 
'versions' and 'newer-version-url' 2 options already added.

2. Check "--with-osid" outputs:
# remote-viewer -V
remote-viewer version 2.0 (OS ID: rhel6)

Result:
OS ID already added


3. Check function for option 'versions' and 'newer-version-url'.

Scenario 1: $versions is equals to virt-viewer version
1.1 Prepare a running guest and configure console.vv file.

# cat console.vv
[virt-viewer]
type=spice
host=127.0.0.1
port=5905
fullscreen=0
versions=rhel6:2.0


1.2 Use remote-viewer to connect vm.
# remote-viewer console.vv

Result: Can connect to guest successfully.


Scenario 2: $versions is less than virt-viewer version

2.1 Prepare a running guest and configure console.vv file.

# cat console.vv
[virt-viewer]
type=spice
host=127.0.0.1
port=5905
fullscreen=0
versions=rhel6:1.0

2.2 Use remote-viewer to connect vm.
# remote-viewer console.vv

Result: Can connect to guest successfully.


Scenario 3: $versions is larger than virt-viewer version

3.1 Prepare a running guest and configure console.vv file.

# cat console.vv
[virt-viewer]
type=spice
host=127.0.0.1
port=5905
fullscreen=0
versions=rhel6:3.0

3.2 Use remote-viewer to connect vm.
# remote-viewer console.vv

Result:Failed to connect to guest, a error window pop up with "At least Remote Viewer version 3.0 is required to setup this connection". After click "OK" button, window closed with no error.

3.3 Add 'newer-version-url' option to connection file:

# cat console.vv
[virt-viewer]
type=spice
host=127.0.0.1
port=5900
fullscreen=0
versions=rhel6:3.0
newer-version-url=http://download.devel.redhat.com/brewroot/packages/virt-manager/1.1.0/10.el7/noarch/virt-install-1.1.0-10.el7.noarch.rpm

3.4 Rerun Step3.2 again.
# remote-viewer console.vv

Result: Failed to connect to guest, a error window pop up with
"At least Remote Viewer version 3.0 is required to setup this connection, see http://download.devel.redhat.com/brewroot/packages/virt-manager/1.1.0/10.el7/noarch/virt-install-1.1.0-10.el7.noarch.rpm for details", after click "OK" button, window closed with no error.
