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 Michal Privoznik 2011-06-03 14:30:42 UTC 
Description of problem:
Currently, QEMU supports taking screenshots of the first monitor only. But once it extends its functionality, libvirt should allow this as well.

Comment 5 Vivian Bian 2011-08-29 08:24:03 UTC 
tested with following rpms[1] , and failed .

Eric , would you please help confirm if I did the correct configuration for guest, and did the right steps to verify this bug ? 

If I was right , then bug status should have been changed to ASSIGNED 

[1] rpms 
libvirt-0.9.4-6.el6
qemu-kvm-0.12.1.2-2.184.el6
kernel-2.6.32-191.el6

Steps :
1. configure guest with multiple spice QXL video devices 
    <video>
      <model type='qxl' vram='9216' heads='1'/>
      <alias name='video0'/>
      <address type='pci' domain='0x0000' bus='0x00' slot='0x02' function='0x0'/>
    </video>
    <video>
      <model type='qxl' vram='9216' heads='1'/>
      <alias name='video1'/>
      <address type='pci' domain='0x0000' bus='0x00' slot='0x07' function='0x0'/>
    </video>
    <video>
      <model type='qxl' vram='9216' heads='1'/>
      <alias name='video2'/>
      <address type='pci' domain='0x0000' bus='0x00' slot='0x08' function='0x0'/>
    </video>
2. start guest 
3. check guest qemu-kvm parameters  :
   qemu-kvm \
   -spice port=5900,tls-port=5901,addr=0.0.0.0,disable-ticketing,x509-dir=/etc  /pki/libvirt-spice \
   -vga qxl -global qxl-vga.vram_size=9437184 
   -device qxl,id=video1,vram_size=9437184,bus=pci.0,addr=0x7 
   -device qxl,id=video2,vram_size=9437184,bus=pci.0,addr=0x8 

4. # virsh screenshot rhel6 /tmp/rhel6
error: could not take a screenshot of rhel6
error: internal error unable to execute QEMU command 'screendump': The command screendump has not been found

# virsh screenshot rhel6 /tmp/rhel6 --screen1

[root@dhcp-93-106 ~]# virsh screenshot rhel6 /tmp/rhel6 --screen 1 
error: could not take a screenshot of rhel6
error: internal error unable to execute QEMU command '__com.redhat_qxl_screendump': An undefined error has ocurred

# virsh screenshot rhel6 /tmp/rhel6 --screen 2
error: could not take a screenshot of rhel6
error: internal error unable to execute QEMU command '__com.redhat_qxl_screendump': An undefined error has ocurred
Comment 7 Vivian Bian 2011-08-31 05:16:00 UTC 
Will try to verify this bug once https://bugzilla.redhat.com/show_bug.cgi?id=729969 get fixed .
Comment 8 yanbing du 2011-10-18 09:11:43 UTC 
Test with following packages:
libvirt-0.9.4-18.el6.x86_64
qemu-kvm-0.12.1.2-2.197.el6.x86_64
kernel-2.6.32-210.el6.x86_64

since there's only windows qxl driver for winXP and win7_x86, only test for these two guests, and can get screen shot by virsh command: screenshot <domain> [<file>] [--screen <number>]. So bug VERIFIED.
