Description of problem: virt-manager should support to modify 'Heads' value of Video in GUI Now libvirt, qemu-kvm, spice support max monitor limitation. virt-viewer can only create one display by default. If we want to create more displays, heads value should be modified. <video> <model type='qxl' ram='65536' vram='65536' vgamem='16384' heads='4' primary='yes'/> <alias name='video0'/> <address type='pci' domain='0x0000' bus='0x00' slot='0x02' function='0x0'/> </video> So it's better to adjust the UI of video device to make heads value editable. Bugs for reference: Bug 1283202 - RFE: backport max monitor limitation from spice-server upstream Bug 1283198 - RFE: backport max monitor limitation from Qemu upstream Bug 1283207 - RFE: implement max_monitor option for qxl video Version-Release number of selected component (if applicable): virt-manager-1.4.1-1.el7.noarch How reproducible: 100% Steps to Reproduce: None Expected results: Additional info:
There's already an RFE tracking multihead support for virt-manager. I don't think we should make the 'heads' valuable editable until that work is done, since heads > 1 is a config that virt-manager can't properly handle yet. So just duping to that RFE *** This bug has been marked as a duplicate of bug 1339289 ***
