Note: This bug is displayed in read-only format because
the product is no longer active in Red Hat Bugzilla.
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.

evidence of actual result
Description of problem:
Multi monitors of virtio-vga works abnormally
Version-Release number of selected component (if applicable):
rhel7.3 host & guest kernel:3.10.0-501.el7.x86_64
qemu-kvm-rhev:qemu-kvm-rhev-2.6.0-22.el7.x86_64
How reproducible:
100%
Steps to Reproduce:
1.Boot guest with cli:
/usr/libexec/qemu-kvm -name rhel73-snapshot-2 -m 1024\
-cpu Haswell-noTSX,check,enforce \
-machine pc \
-smp 3,threads=2,cores=1,sockets=3,maxcpus=6 \
-serial unix:/tmp/m,server,nowait \
-drive file=l73.qcow2,if=none,id=drive-scsi-disk0,format=qcow2,cache=none,werror=stop,rerror=stop -device virtio-scsi-pci,id=scsi0,disable-modern=off,disable-legacy=off -device scsi-hd,drive=drive-scsi-disk0,bus=scsi0.0,scsi-id=0,lun=0,id=scsi-disk0,bootindex=1 \
-monitor stdio \
-netdev tap,id=idinWyYp -device virtio-net-pci,mac=42:ce:a9:d2:4d:d7,id=idlbq7eA,netdev=idinWyYp \
-qmp tcp:localhost:4444,server,nowait \
-device virtio-vga,max_outputs=2 \
-spice port=3003,disable-ticketing,agent-mouse=on\
-nodefaults \
-device virtio-serial-pci -chardev spicevmc,id=vdagent,debug=0,name=vdagent \
-device virtserialport,chardev=vdagent,name=com.redhat.spice.0 \
2.Remote connect to guest: remote-viewer spice://host_ip:3003
3.Enable multi monitors from remote-viewer: View -> Displays -> Display 2
Actual results:
Multi monitors of virtio-vga works abnormally, only display 1 can be used to operate
Expected results:
Multi monitors of virtio-vga behave like qxl
Additional info:
photo evidence to show actual result.
There have been known issues on both host and guest, fixed meanwhile, the
7.4 rebases (qemu-kvm-rhev and kernel drm drivers) should pick up the bugfixes.
Extend displays won't get guest desktop graphic automatically after guest reboot and login to Desktop, bug id:
Bug 1460595 - [virtio-vga]Display 2 should be dropped when guest reboot
But this is a minor case, won't block 1374237, so mark as verified.
