[Adding spice-devel@ back - I don't think we should drop this list, even if it will be a repost there.] I've just a small comment below, -- I haven't gotten to testing it myself yet, was too busy today to do anything useful. 25.01.2013 18:37, Fabio Fantoni wrote: > Debugging qxl problem with xen I tested first qemu without xen and I found that qxl memory mapping problem is not only xen related. > After some tests with qemu-only I found that -global qxl-vga.vram_size=N and -global qxl-vga.ram_size=N (where N is for example 16384 or 65536) are bugged. > Qxl ram regions with these parameters on all test are always: > > qxl-0: ram/pri: 32 MB [region 0] > qxl-0: vram/32: 0 MB [region 1] > qxl-0: vram/64: 0 MB [unmapped] > > Qemu crashes when start using qxl. > For full log of one test with this problem see attachment qemulog1 > > Without -global qxl-vga.vram_size=N and -global qxl-vga.ram_size=N qxl ram region it seems correct and qemu doesn't crash. > For full log of such test see attachment qemulog2 > > With -global qxl-vga.vram_size_mb=N and -global qxl-vga.ram_size_mb=N it seems correctly working. > For full log of such test see attachment qemulog3 > > About qxl with xen there are other problems. > Is there a way to understand that is an effective xen problem and not on qemu?

I haven't noticed this -- will switch in the next release, -- seavgabios in debian is already available, the only thing needed is to change the vgabios-* symlinks in /usr/share/qemu to point to seabios binaries instead of vgabios binaries.
