Hi Ramkumar, I know you have already said that the VLANs are configured correctly, but 99.99% of the time when you have these symptoms it is related to misconfigured VLANs
Please triple check your VLAN configurations, and even try rebooting the switch to ensure the configuration has been applied correctly.

Jegannathan Subject: VM instance cannot aquire IP via DHCP when run on other host with Virtual Router Hi Team, We setup cloudstack with Advance Network with two xenserver host with Isolated Guest Network. Vm's are creating with virtual router in host1 and able to acquire IP address. But the issue is when we migrate the VM to host2 the vm instance cannot aquire IP from virtual router which is located in host1. Exact Issue: when vm and virtual router separated between 2 hosts the DHCP request is not passing to from 1 host to another host. Note: - 1. Both xenservers and cloudstack server are configured in the same vlan. 2. Xenservers physical nic's is configured as trunk port in physical switch and allowed to pass all guest vlan traffics. 3. Configured correct traffic label in cloudstack physical network setup and same has been synced with xenserver's . Kindly let us know what is the cause for not getting ipaddress when vm and router are separated. Your quick response is much appreciated. Thanks.
