Re: [libvirt-users] [help] How to modify the vgamem value ?
Hi Luo,
the vgamem is limited inside. Myself, I use QEMU 2.5/Virgil3D to expand
the vgamem.
May be someone have a better solution or an example to solve it.
Best regards,
Holger

example:
<domain type='kvm'
xmlns:qemu='http://libvirt.org/schemas/domain/qemu/1.0'>
.
.
<!-- Begin device declaration -->
<devices>
.
.
<!-- Videocard -->
<video>
<model type='virtio' heads='1'/>
<alias name='video0'/>
<address type='pci' domain='0x0000' bus='0x00'
slot='0x0b'
function='0x0'/>
</video>
.
.
.
<!-- End device declaration -->
</devices>
<qemu:commandline>
.
.
<qemu:arg value='-global'/>
<qemu:arg value='VGA.vgamem_mb=128'/> <--- here is the size
<qemu:arg value='-set'/>
<qemu:arg value='device.video0.driver=virtio-vga'/>
</qemu:commandline>

Dear everyone
Do you know how to modify vgamem value in the .xml file ? such as :
<video>
<model type='qxl' ram='65536' vram='65536'
vgamem='16384'
heads='1'/> // from instance-0000015e.xml
<address type='pci' domain='0x0000' bus='0x00'
slot='0x02'
function='0x0'/
</video>
I plan to increase the volume of vgamem , but it seems that always
keep the original value ‘16384’. Was it limited by QEMU? or others？
Please tell me how I can I modify it ? it's better that help me to make
a example for modifing the vgamem.....
Thank you very much
Best Regards .
