This does not survive a reboot of the domU though.

OK. Look at the file /usr/lib/xen-tools/debian.d/55-create-dev.

  Inside it there are these lines:

  #
  # Make the device nodes.
  #
  cd ${prefix}/dev
  ./MAKEDEV generic

  After that add './MAKEDEV std' and try to create a new domain. If
 that works please let me know and I'll commit it to CVS.

However, checking my 55-create-dev script, I see a possible typo as
the email says "std" but the script says "sd".

[root at centos5-dom0 ~]# grep MAKEDEV /usr/lib/xen-tools/debian.d/55-create-dev
./MAKEDEV generic
./MAKEDEV sd
[root at centos5-dom0 ~]#

I also see an unusual message, "rtc: IRQ 8 is not free." as the last
line of dmesg, and the following it output on the console during boot:

- - - 8< - - -
Setting the system clock..
rtc: IRQ 8 is not free.
modprobe: WARNING: Error inserting rtc
(/lib/modules/2.6.18-4-xen-686/kernel/drivers/char/rtc.ko):
Input/output error

Generic RTC Driver v1.07
select() to /dev/rtc to wait for clock tick timed out

Also, since "./MAKEDEV generic" took a long time, I found that a
faster way to get OpenSSH running is:

# cd /dev ; ./MAKEDEV urandom ; /etc/init.d/ssh start
