After doing:
        make world
        make install
        make twister-install (or install-twister, whichever)

and setting /boot/grub/menu.lst to
        title Xen-unstable  / XenoLinux 2.4.24
        kernel /boot/xen.gz dom0_mem=131072 ser_baud=115200 noht
        module /boot/vmlinuz-2.4.26-xen0 root=/dev/sda1 ro console=tty0

and rebooting into the above entry, I get the following error when executing

        xend start

[root@sloth rountree]# xend start

There isn't a /var/run/xend directory, much less a /var/run/xend/xendsock 
file.  grep isn't too helpful:

[root@sloth xeno-unstable.bk]# grep -r xendsock *
install/lib/python/xen/xend/server/params.py:MGMT_SOCK    = 'xendsock' # 
relative to CONTROL_DIR
Binary file install/lib/python/xen/xend/server/params.pyc matches
tools/python/xen/xend/server/params.py:MGMT_SOCK    = 'xendsock' # relative to 
CONTROL_DIR
tools/python/build/lib.linux-i686-2.3/xen/xend/server/params.py:MGMT_SOCK    = 
'xendsock' # relative to CONTROL_DIR

nor does xendsock appear to be a file that gets installed -- "find" doesn't 
locate it in the build directory.

Sooo.... I think I'm missing something obvious.  Any hints?

Thanks,

Barry
 
PS:  Hmmm... buried in all of that verbiage is "Xend Daemon started".  Is it 
safe to ignore this error?
