I'm not sure about Xen, but VMware suppots hot-add NICs.

The behavior of not creating ifcfg-eth1 is linux and not cloudstack.

If you add NICs before you power on guest vm for the first time, it will detect multiple nics and create ifcfg interface files.

I have the same behavior on VMware with or without CloudStack. CloudStack (or vCenter without CloudStack) adds virtual nic, which is presented if you run "dmesg" or "ifconfig -a" - while VM is up and running.

From there on, CloudStack has no insight into vm, its linux admins responsibility to script or add interface file manually.

See if reboot helps.

Hi liya,

I tried with "Add Network to VM" by selecting other VLAN.
On Cloudstack UI Its showing IP but in CentOS its not creating ifcfg-eth1
file.
Xen-tools are installed on CentOS.
