[Xen-devel] Passing IP Parameters in 3.0

[sde 9000 <sde9000@xxxxxxxxx>]

After having tried XenOS 4.2, Fedora Core 4, Fedora Core 5T1 as hosts and same sample plus fc3 and suse as guests it appears that passing the IP parameters from the domU configs idoes not want to work (dom0 and domU dumps attached). The only parm getting passed is the mac address, which shows up on the guest nicely. 

Any attempt at getting a VM's IP configured through the below wouldn't do:

ip = "10.0.0.2"
netmask = "255.255.192.0"
gateway = "10.0.0.1"
hostname ="vm010000000002"
vif = ['mac=aa:00:00:11:00:11, bridge=xenbr0']
disk = ['file:/mnt/root/xen/centos-full.img,sda1,w']
root = "/dev/sda1 ro"
#console = "10002"


DHCP works. Manually configuring the IP parms in the guest after boot (plus putting the bridge device into the same subnet) leads to being able to ping both hosts in any direction, but ssh to the guest along with apparently domain sockets within the guest failing. 

Also, changing cat xend-config.sxp to nat through bridivif-nat and network-nat seems not work at all - with no xenbr0 being created in this case. 

So how do you get 3.0 to pass the ip config to the guests? How do you enable nat-work around eventual issues there? -  A full dump of the xen, ip config on host and guest ist attached. Any help would be appreciated - thanks in advance.
