RE: [Xen-devel] [PATCH 1/1] Xen ARINC 653 Scheduler (updated to add support for CPU pools)

["Kathy Hadley" <Kathy.Hadley@xxxxxxxxxxxxxxx>]

I downloaded the xen-unstable staging tree, through changeset 21632.
After building ("make xen", "make install-xen", "make tools", "make
install-tools", "make stubdom" and "make install-stubdom") and
restarting, xend is not running (attempting to execute "xm list" returns
"Error: Unable to connect to xend: No such file or directory. Is xend
running?").

/var/log/xend.log contains the following:

Any suggestions?
