I've created 4.0.1-rc2-pre -  xen-4.0.1.fc13.src.rpm for F13
and rebuild & reinstalled xen's rpms. Hot Hypervisor upgrade up to 4.0.1-rc2-pre
Kernel 2.6.32.15.

Pasi and myself noticed problems with VNC. Virt-installs run only text mode,
otherwise hang on top Ubuntu 10.04 Server. It DOESN'T happen on top of F13
However,  at runtime on F13 :-
VNC console hangs for Lucid PV Guest at Xen 4.0.1 Dom0 (.15 kernel) on top F13
VNC console works for  F13 PV   Guest at Xen 4.0.1 Dom0 (.15 kernel) on top F13

It worked fine say for .12 or .13 kernels.

Looks like network communication problem with VNC.
It's testing environment. But any customer watching  so unstable picture, won't be happy.

Things are pretty bad in the meantime, if they use a pvops kernel.
Maybe I should create a specific xen 4.0.0 branch?

Any chance of a hotfix for just this particular issue?
