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.

Description Radek Duda 2017-08-01 12:42:03 UTC 
Created attachment 1307549 [details]
vdagent.log within reconnection

Description of problem:
After reconnection VM guest top up the number of attached displays to correlate number of qxl devices


Version-Release number of selected component (if applicable):
client: rhel7.4 tested:
virt-viewer-5.0-7.el7.x86_64
spice-gtk3-0.33-6.el7.x86_64
spice-protocol-0.12.12-2.el7.noarch
qemu-kvm-rhev-2.9.0-16.el7_4.3.x86_64

guest: Win10-64bit
spice-qxl-wddm-dod-0.18-1
vdagent-win-4.1-3


How reproducible:
always

Steps to Reproduce:
1.Setup Win10 VM with multiple qxl devices and launch it (not in fullscreen)
2. connect to it with remote-viewer
3. reduce number of attached displays (remote-viewer menu-> View-> Displays)
 * notice that number of attached displays is accordingly reduced within Win10 guest (in 'Advanced display settings' dialog box)
4. reconnect to VM with remote-viewer

Actual results:
Number of attached displays is topped up to the number of guest's qxl devices

Expected results:
Number of attached displays stays the same before and after reconnection.

--spice-debug -debug log after reconnection
Comment 3 Radek Duda 2017-08-02 11:16:56 UTC 
This applies not only for reconnection but also for migration (tested using using rhv 4.1.5-0.1.el7):
Right after Windows 10 VM is migrated, number of attached displays is increased to the number of qxl devices of the VM. So several remote-viewer windows suddenly pop up.
Comment 4 Yaniv Kaul 2017-12-03 16:06:12 UTC 
I don't see this getting into 4.2.0 - please re-target.
Comment 5 Sandro Bonazzola 2019-01-28 09:41:31 UTC 
This bug has not been marked as blocker for oVirt 4.3.0.
Since we are releasing it tomorrow, January 29th, this bug has been re-targeted to 4.3.1.
Comment 7 Radek Duda 2019-02-13 13:28:28 UTC 
Any progress there? I reproduced this using rhv4.3
and rhel8 client/win10 guest(vdagent-win-4.1-5) again
Comment 8 David Blechter 2019-02-18 15:46:18 UTC 
not a blocker for 4.3.

Yuri, 
please, investigate and update.

thanks, dnb

vdagent.exe (fix candidate)
Comment 12 ybendito 2019-03-11 13:23:59 UTC 
Please check whether attached executable (comment #11) solves the problem (x64):
from administrator command prompt:
sc stop vdservice 
sc qc vdservice -> to see the path of executables
copy attached vdagent.exe overriding existing
restart
Comment 13 Radek Duda 2019-03-11 14:25:12 UTC 
It behaves all right with your new fix.
Reproduced with current vdagent. 
Installed yours with a fix.
I opened Win10 with 4 displays, closed one -> reconnected by remote-viewer -> only three displays were opened

Repeated several times with various number of opened VM displays.
Comment 14 Sandro Bonazzola 2019-03-12 12:54:19 UTC 
4.3.1 has been released, please re-target this bug as soon as possible.
Comment 15 Sandro Bonazzola 2019-04-10 06:30:42 UTC 
Is there an upstream release / downstream build including this fix?
Comment 16 Victor Toso 2019-04-10 07:50:14 UTC 
Hi Sandro,

> Is there an upstream release / downstream build including this fix?

Upstream I'm sure there isn't but I'll be preparing the releases Today and do one Tomorrow, I'll include win32/vd-agent too.

Downstream, It doesn't seem like it too? Unless I'm looking in the wrong place.

Moving back to POST, when build is done, added to errata, the fixed in version must be added.

Cheers,
