[Xen-users] Xen 3.3 NetBSD DOM0: xenconsole: Could not read tty from store: No such file or directory

[Ron McDowell <rcm@xxxxxxxxxxx>]

Hi Xen-users. 

Trying to bring up xen 3.3 on a Dell T110 running NetBSD 5.1 amd64 
DOM0.  I installed the OS from CD, then xentools33 and xenkernel33 with 
pkg_add, and I got DOM0 working...

I created a big disk image file with dd...

[root@voodoo(NetBSD)]> ls -l /Xen/Disks/juju.img
-rw-r--r--  1 root  wheel  966367641600 Oct 11 22:40 /Xen/Disks/juju.img


And have my bridge set up...

[root@voodoo(NetBSD)]> cat /etc/ifconfig.bridge0
create
!brconfig $int add bge0 up
[root@voodoo(NetBSD)]> ifconfig bridge0
bridge0: flags=41<UP,RUNNING> mtu 1500

I want to use HVM for transparency [over speed]... but if I use this 
config file [basic HVM with disk/memory/mac changes...I want to boot and 
install FreeBSD from the ISO file]...
kernel = "/usr/pkg/lib/xen/boot/hvmloader"
builder='hvm'
memory = 1024
name = "juju"
vif = [ 'mac=00:16:3e:xx:xx:xx, bridge=bridge0, type=ioemu' ]
device_model = '/usr/pkg/libexec/qemu-dm'
disk = [ 'file:/Xen/Disks/juju.img,ioemu:hda,w', 
'file:/Xen/CDs/FreeBSD-8.2-RELEASE-i386-disc1.iso,ioemu:hdc:cdrom,r' ]
boot='d'
usb=1
usbdevice='tablet'


when I try to create it:

[root@voodoo(NetBSD)]> xm create -c /Xen/Machines/juju.cnf
Using config file "/Xen/Machines/juju.cnf".

[root@voodoo(NetBSD)]> xm console juju
xenconsole: Could not read tty from store: No such file or directory

I found something online about xenconsoled might not be running...it was 
not being started but I added it to /etc/rc.local, so it now starts up:
[root@voodoo(NetBSD)]> ps -ax|grep xen
222 ?     I    0:00.60 xenstored --pid-file /var/run/xenstore.pid
223 ?     Il   0:00.00 xenconsoled 228 ?     I    0:00.00 
/usr/pkg/bin/python2.6 /usr/pkg/sbin/xend start
233 ?     Il   0:02.72 /usr/pkg/bin/python2.6 /usr/pkg/sbin/xend start
238 ?     Isl  0:00.01 /usr/pkg/sbin/xenbackendd
2134 ttyp0 S+   0:00.00 grep xen

This DOM0 box is headless and I don't want or need [do I??] X on it.

What am I missing?  Thanks.
