Description Xiaodai Wang 2017-03-20 08:49:33 UTC
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:

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
