New XEN Pacakge brakes XEN on x86_64

[lax]

Not sure I'm suppose to post this here:

New XEN package xen-3.0.1-0.20060301.fc5.3 brakes the xen functionality.
The userspace message is:
Unable to open xenstore
Which is an error from the newly added feature to xen to allow xenstat to use xenstore


The xend.log file contains:
[2006-03-04 17:23:21 xend] ERROR (SrvDaemon:292) Exception starting xend ((111, 'Connection refused'))

-------------

Reverting back to old xen rpm (from test 3) will work with OLDER kernel ( hypervisor 1955FC5) but not (2009FC5)

This also breaks Xen on non-64 bit (i.e., x86) systems.

From the Fedora Test list:

To workaround the problem,

service xend stop
cd /dev
MAKEDEV /dev/kmem
service xend start

I have verified that this allows the latest xen package to work with the 2009FC kernel.

Tested and confirmed in x86_64

Thanks for the info!

has to be reexcuted on every boot. probably needs to be automated
