NetBSD-Current/XEN3 : XM CREATE problem

Hi all,

Well, I'm trying to use Xen3 with NetBSD 3.99.22.

The Xen3_DOM0 kernel successfully boot on my Athlon64.X2 and
"see"  
the dual core ... ( that was not possible before with Xen2 -
Thanks  
manuel )
The sysutils/xenkernel30 & sysutils/xentools30 compile
fine from  
PKGSRC ( using GCC4 ) ...

At this point, everything's up & running 

BUT :

I'm not able to run "xm create " ... It fails
with the following error :

xm create -c ./test
Using config file "./test".
Error: Device 0 (vif) could not be connected. Hotplug
scripts not  
working.

Here is my config file :

kernel = "/root/netbsd-INSTALL_XEN3_DOMU"
# kernel = "/root/netbsd-XEN3_DOMU"
memory = 128
name = "test"
cpus = ""
vif = [ 'bridge=bridge0' ]
disk = [ 'phy:/dev/wd0h,wd0d,w' ]
root = "/dev/wd0d ro"

For bridge I have in /etc/ifconfig.bridge0 :

create
!brconfig $int add re0 stp re0 up

I also get the following errors ( using dmesg ) :

xbdback: can' read backend/vbd/1/3/handle: 79
xbdback: can' read backend/vbd/1/3/handle: 79

Did I missed something in my configuration ?

Any idea ?

I read through the archives and looks like you need to
change wd0d
to 0x03.

Yeah, this solve a part of my problem ...

xm create -c ./test
Using config file "./test".
Error: Device 0 (vif) could not be connected. Hotplug
scripts not  
working.

Same error 

But, this solves the following error :

xbdback: can' read backend/vbd/1/3/handle: 79

Maybe I missed the VIF/Bridge configuration

many thanks

Well,

I've made some tests and read some documentation .... 

I forgot to start xenbackend daemon  This
solve the error I've  
posted before without using "0x03" :

==> xbdback: can' read backend/vbd/1/3/handle: 79

But the "xm create" still not work ... :(

==> Error: Device 0 (vif) could not be connected. Hotplug
scripts not

Any idea ?

Do I need a ifconfig.bridge0 like in xen 2.0.7 ?

Is there any parameters to setup in xend-config.sxp ?

Many thanks ...

Well, it seems to work :

Here is what i did :

my config file is "test" :

#-----------------------------------------------------------
------------ 
-----
kernel = "/root/netbsd-INSTALL_XEN3_DOMU"
# kernel = "/root/netbsd-XEN3_DOMU"
# ramdisk = "/boot/initrd.gz"
# builder='linux'
memory = 128
name = "test"
# List of which CPUS this domain is allowed to use, default
Xen picks
#cpus = ""         # leave to Xen to pick
#cpus = "0"        # all vcpus run on CPU0
#cpus = "0-3,5,^1" # run on cpus 0,2,3,5
# vcpus = 1
# vif = [ '', 'bridge=xenbr1' ]
# vif = [ '', 'bridge=bridge0' ]
# vif = [ '' ]
# vif = [ '', 'bridge=xenbr0' ]
disk = [ 'phy:/dev/wd0h,0x03,w', 'phy:/dev/cd0a,0x04,r'
]
# disk = [ 'phy:/dev/wd0h,0x03,w' ]
root = "/dev/wd0d ro"
extra = "4"
#-----------------------------------------------------------
------------ 
-----

With this, I have successfully install NetBSD.DomU ...

But at this point I still have no network :(

I've tried many configuration parameters in xend-config.sxp
without  
any success

Any idea ?

SOLVED :

Here are the configuration that works for me :

On Domain0 / NetBSD 3.99.22 / Xen 3.0.2.2 :

/etc/ifconfig.bridge0 ( "re0" is my default
network device )
------------------------------------------------------------
-----------
create
!brconfig $int add re0 stp re0 up
------------------------------------------------------------
-----------
/usr/pkg/etc/xen/xend-config.sxp : changing the following
line

(network-script network-bridge)
by this one :
(network-script 'network-bridge netdev=re0')

And finally : the configuration file itself :
------------------------------------------------------------
-----------
kernel = "/root/netbsd-XEN3_DOMU"
memory = 128
name = "test"
#cpus = ""         # leave to Xen to pick
#cpus = "0"        # all vcpus run on CPU0
#cpus = "0-3,5,^1" # run on cpus 0,2,3,5
# vcpus = 1
vif = [ 'bridge=bridge0' ]
# disk = [ 'phy:/dev/wd0h,0x03,w',
'phy:/dev/cd0a,0x04,r' ]
disk = [ 'phy:/dev/wd0h,0x03,w' ]
root = "/dev/wd0d ro"
------------------------------------------------------------
-----------

Hope these tests will help ...

Best Regards

Arnaud.
