Bug Description

Hi,

I'm surprized this bug wasn't already reported, perhaps I missed the dup; when ever I'm scrolling in the linux console of a kvm host, I get garbled output with letters in random places.

Will attach a screenshot of vi /var/log/syslog, before and after moving the cursor below the last displayed line.

This happens in aptitude, and sometimes even when doing things like "ifconfig" in the console, but not always.

It also happens when switching VTs.

Just doing a ^L is usually enough to clear the problem.

Bye

I see this too when going from X to a console. See attached screenshot.

And I can confirm too.

I'm just running kvm from the command line.

I do something simple, such as `cat /proc/cpuinfo` and after roughly the 10th time, my screen goes to garbage.

This happened while I was working with Anthony Liguori on Friday and he knew of the issue. I will take this up with upstream kvm.
