Red Hat Bugzilla – Bug 239990
Boot screens have corrupted graphics
Last modified: 2008-08-02 19:40:34 EDT
Description of problem:
When booting virtual machines, the screen graphics often (nearly always) are
corrupt. See attachment.
Version-Release number of selected component (if applicable):
virt-manager 0.4.0, Fedora 7 Test 4
I'm using openSUSE 10.3 Alpha 3 (both booting the installer and the installed OS
in a VM). The problem was also manifested itself with Windows 2000 Professional
installer (there were also minor graphics errors throughout the w2k installer
process on the blue install screens).
Steps to Reproduce:
1. Create a new VM under virt-manager using Full Virtualization with hardware
acceleration. I have a dual Opteron 2214 setup. I'm using an e-GeForce 7600GT
PCI-X 16x video card. I have not installed any video drivers beyond what came
with Fedora 7 Test 4.
2. Boot off of a Windows 2000 Professional or openSUSE 10.3 Alpha 3 disk. The
initial screens and some subsequent screens have graphics corruption. Usually
the first screen or two is major, leading to an unreadable screen (see
attachment of installed guest OS booting), subsequent screens (such as w2k
installer blue screens) are minor.

Screenshot of openSUSE 10.3 Alpha 3 booting in guest VM.
Sorry, it's a PCI-Express card, not PCI-X as I stated above.
In the screenshot it appears I am booting Fedora 7. I want to make it clear I
was booting openSUSE 10.3 Alpha 3. It appears part of the corruption involves
errantly copying from the video memory of the host OS.
What happens if you close the console window & re-open it immediately? Does the
corrupt graphics rectify itself. At first guess I'd say this was a dup of bug
238831 in which the VNC server does not send correct refreshes after a
resolution change. If this is correct, closing & reopening the console window
would clear the corruption.
