Multiple IP in Guest VM
Hi,
I have 2 diff VLAN created by "default shared Network offering". I want to
assign one ip from both VLAN to Linux guest VM. Is it possible ? I am using
CS 4.3 with Xen 6.2 SP1.
Regards,
Tejas

Hi,
It was good help.
/etc/sysconfig/network-scripts/ has net.hotplug file. Need to check what it
does.
Regards.

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.
Regards
ilya

we have to manually configure on server side.
Refer this :
https://cwiki.apache.org/confluence/display/CLOUDSTACK/Multiple+IP+address+per+NIC
JFYI:
Cloudstack:
User requests for the association/dissociation of the IP address for the guest VM NIC via CS API/UI. CS reserves an IP and gives to the User.
One NIC can be associated with multiple IP address.
Note: User can specify the IP address from the guest subnet if not CS picks the IP from the guest subnet.
User Role:
User need to manually configure the requested IP for the NIC in the VM.
2. Cloudstack will not configures the IP for VM.
3. User need to provide to which NIC, the IP should be associated.
regards
sadhu

You may need to stop/start the vm for the nic to be created. I am not sure whether nic hot-plugin is supported.

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.

You have add network feature under NICs view of the VM.
