Ezpeer,

Thanks for your support such a long time.

This morning, when I retry creating network just as what I did before, It works. Yes, It works!!!

But I completely have no idea what I modified, even I suspect I changed nothing but it goes well now.

I can not reproduce this issue, I just decided continue my starlingx trip.

Anyway, thanks a lot.

Best Regard

Dear Qianjiang,
system host-lock ${COMPUTE} 

#If the interface has been bound to other datanetwork, need to remove the binding.
system interface-datanetwork-list ${COMPUTE}
system interface-datanetwork-remove ${PHYSNETDATA0UUID}

#Create a flat datanetwork and bind it to the interface.
system datanetwork-add phy-flat flat 
system host-if-modify -m 1500 -n data0 -c data ${COMPUTE} ${DATA0IFUUID} 
system interface-datanetwork-assign ${COMPUTE} ${DATA0IFUUID} phy-flat 
system host-unlock ${COMPUTE}
My Example:

[sysadmin@controller-0 ~(keystone_admin)]$ system host-if-list controller-0
