Hello,
after upgrading to Xen 3.4.1 on one of my hosts I have problems starting my PV domUs that are configured to use pygrub. 
When issuing "xm create <domU>" I get the following error message:
Boot loader didn't return any data!
Strange enough it worked before and it even still works when invoking xm create with "-c" (attached console)... 
And yes, the kernel is present on the *first* phy-device.
Here the logs from a xm create (without "-c")
