Re: [Xen-users] Is it possible to increase screen resolution of DomU?

[Sergey Zhukov <svg@xxxxxx>]

I tried to set up 
videoram=8
videoram=16
videoram=32
videoram=64

Maximal resolution is 640x480 anyway, and I can get only maximum of 16M
memory in videocard despite of videoram setting.  

in DomU 
stdvga=1, videoram=8
