X server log from the guest
Description of problem:
I created a Rawhide virtual machine on a Fedora 10 host (both x86-64). I cannot get a display resolution of higher than 800x600 in the guest. Xorg.0.log shows complaints about both bad modes and insufficient memory for modes. (I allocated 1 GB of RAM to the guest, but I have no idea how video memory is allocated.)
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. Start up my Rawhide guest
The display is 800x600, with higher resolutions marked unusable.
I would like to get something a little higher, maybe 1024x768.
Currently we just emulate curris chip which is not able to do anything better. Adam Jackson advised me at least on workaround:
[00:31:07] ajax: only workaround for now is to run kvm with -std-vga and configure vesa for whatever resolution you want by hand.
Otherwise, this is NOTABUG. We will emulate some better chip eventually.
