Use different video device '-vga std' instead of '-vga cirrus' for KVM guest VMs

[Karan .]

Hi All

I am on CLOUDSTACK 4.1.1.
If i ask my question in terms of qemu ,how can I use '-vga std' video
device for my guest VMs.
Or in terms of libvirt, how can I use   vga video device for all Domains.
<video>
     <model type='vga'/>
</video>

Does cloudstack provides any way for changing these machine
properties. Currently all VMs are provided with 'cirrus',however I
have seen 'std' giving better display for guest VMs.
