text console display bit garbled
Last modified: 2008-04-04 00:43:20 EDT
Description of problem:
When using the console in text mode the background is garbled which
makes the text hard to read.
Steps to Reproduce:
1. start a virtual console from virt-manager
2. look at OS in text console mode
consistent black background
Works ok in qemu console for instance.

This is a bug in the QEMU VNC server I believe. I see the same kind of
corruption when using a regular 'vncviewer' client. It seems to particularly
occur when changing resolutions.
So it is a qemu bug?
This bug is trivially reproducable with current QEMU cvs HEAD, simply by booting
the Fedora Core 6 boot.iso on i386
dd if=/dev/zero of=foo.img bs=1M count=0 seek=1024
qemu -hda foo.img -cdrom boot.iso -boot d -vnc :1 &
On the very first text mode switch - from syslinux to booting the kernel, the
pattern shown in #1 will be seen.
I did a quick hack forward porting Xen's tools/iommu/patches/vnc-fixes patch
file to work with QEMU & this solved the problem. I'll do a real forward port &
send it to upstream QEMU for comment & attach a version suitable for QEMU 0.9.0
