vRam and Graphics Acceleration

[David Ortiz]

Hello,
     Is there any mechanism in cloudstack to modify vRam settings and enable 3d 
graphics acceleration?  We are trying to troubleshoot some graphics bugs with a 
guest VM, and have found how to adjust these settings in libvirt, but I have 
not found any documentation on how to access them through cloudstack, which is 
where the change needs to happen since the libvirt file will get changed on vm 
restart.
Thanks,     David Ortiz
