RE: How to set up a NAT networking for xen 4.2.5 domu without xend-config.sxp

[Fu, Zeyi (付泽义) <Zeyi.Fu%mtuzhuhai.com@localhost>]

Ah, there it is, thanks. But it doesn't work for me.

First of all, I set up a hvm domu with the bridge mode, it works fine. Here it is:

--------------------------------------------------------------------------------------------------
#kernel = '/usr/pkg/lib/xen/boot/hvmloader'
builder = 'hvm'
memory = '4096'
vcpus = 2
#device_model = '/usr/pkg/libexec/qemu-dm'

disk = [ 'file:/data/xen/xenDomU/DomU1-Win7/win7_1.img,ioemu:hda,w',
	 'phy:/dev/cd0a,hdc:cdrom,r']

name = "DomU1-Win7"
vif = [ 'type=ioemu,bridge=bridge0' ]
acpi = 1
apic = 1
boot = 'dc'
vnc = 1
serial = 'pty'
usbdevice = 'tablet'
-----------------------------------------------------------------------------------------

Then I set the vifscript=vif-ip in the xl.conf:

-----------------------------------------------------------------------------------------------
## Global XL config file ##

# automatically balloon down dom0 when xen doesn't have enough free
# memory to create a domain
#autoballoon=1

# full path of the lockfile used by xl during domain creation
#lockfile="/var/lock/xl"

# default vif script 
#vifscript="vif-bridge"
vifscript="/usr/pkg/etc/xen/scripts/vif-ip"

# default output format used by "xl list -l"
#output_format="json"

# first block device to be used for temporary VM disk mounts
#blkdev_start="xvda"

# default option to run hotplug scripts from xl
# if disabled the old behaviour will be used, and hotplug scripts will be
# launched by udev.
#run_hotplug_scripts=1
-----------------------------------------------------------------------------------------------------

And change the vif value in the domu configuration file:

-------------------------------------------------------------------------------------
#kernel = '/usr/pkg/lib/xen/boot/hvmloader'
builder = 'hvm'
memory = '4096'
vcpus = 2
#device_model = '/usr/pkg/libexec/qemu-dm'

disk = [ 'file:/data/xen/xenDomU/DomU1-Win7/win7_1.img,ioemu:hda,w',
	 'phy:/dev/cd0a,hdc:cdrom,r']

name = "DomU1-Win7"
#vif = [ 'type=ioemu,bridge=bridge0' ]
vif = ['ip=10.0.0.2/24']
acpi = 1
apic = 1
boot = 'dc'
vnc = 1
serial = 'pty'
usbdevice = 'tablet'
----------------------------------------------------------------------------------------------

The domu doesn't work any more. Here are outputs when I run xl create:

Libxl: error: libxl_dm.c:12223:device_model_spawn_outcome: domain 7 device model:spawn failed (rc=-3)
Daemon running with PID 1244
Xenconsole: Could not read tty from store: No such file or directory
Libxl: error: libxl_exec.c:118:libxl_report_child_exitstatus: console child [0] exited with error status 2


#xl list

Domain-0                                     0  1024     1     r-----      53.7

But I can see that the xvif interface is created successfully

#ifconfig -a
urtwn0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 1500
	ssid default nwkey 65536:"",0xc1520e70c1adff6b9ea83fb3b2fc31b5,"",""

There should be something wrong when I change the networking to NAT.

there is /usr/pkg/etc/xen/xl.conf, doens't this work for you ?
