Re: Multiple IP in Guest VM
Hi, It was good help. /etc/sysconfig/network-scripts/ has net.hotplug file. Need to check what it does. Regards.

RE: Multiple IP in Guest VM
You may need to stop/start the vm for the nic to be created. I am not sure whether nic hot-plugin is supported. -Sanjeev -Original Message- From: Tejas Gadaria [mailto:refond.g...@gmail.com] Sent: Wednesday, June 25, 2014 9:52 AM To: users@cloudstack.apache.org Subject: Re: Multiple IP in Guest VM Hi liya, I tried with Add Network to VM by selecting other VLAN.

RE: Multiple IP in Guest VM
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 -Original Message- From: Sanjeev Neelarapu [mailto:sanjeev.neelar...@citrix.com] Sent: 25 June 2014 10:13 To: users@cloudstack.apache.org Subject: RE: Multiple IP in Guest VM You may need to stop/start the vm for the nic to be created.
