Public bug reported:

Hello!

Booting Kubuntu edgy as Xen dom0 makes my keyboard unusable under X11.
It gets very sluggish, meaning that there is a varying delay between key
press and printing of a character on the screen and that some characters
are doubled.

After logging in to X11, the keyboard first behaves as it should, but at
the time kdewallet asks for the wallet passphrase (which is usually the
last thing that happens when the session is restored), the keyboard
starts to behave like this.

I have installed the following packages:

libc6-xen (2.4-1ubuntu12)
libxen3.0 (3.0.3-0ubuntu1)
python-xen3.0 (3.0.3-0ubuntu1)
xen-docs-3.0 (3.0.3-0ubuntu1)
xen-hypervisor-3.0-i386 (3.0.3-0ubuntu1)
xen-image-xen0-2.6.17-6-generic-xen0 (2.6.17-6)
xen-restricted-modules-2.6.17-6-generic-xen0 (2.6.17-3)
xen-utils-3.0 (3.0.3-0ubuntu1)

The problem seems to be (K)Ubuntu specific, as it does not happen with
the Xen 3.0.3 live CD.

I have suspected it might be a kernel/hypervisor problem and tried the
latest unstable XEN kernel/hypervisor (from xen-unstable.hg) without
replacing the user space tools, but the problem still occurs.

I have also suspected, that my CPU is detected wrong, because I have a
Pentium 4 1.8 GHz which the hypervisor rightly detects as such but the
dom0 kernel (from the package and also the xen upstream kernel) reports
a 2 GHz Pentium.

Read U!
