@weizhouapache Appreciate the help. Listed below are answers to your questions. - I am able to ping google from the CloudStack Virtual Router. - I am able to ping google from the VM I quickly spun up using the centos template that comes with cloudstack. - One of the KVM host and the Management Server is running on one physical is running on 1 bare metal physical ubuntu system, the second host is running on another baremetal physical ubuntu system. **_Additional Tests I performed_** Based on what I came across so far, my mtu size for ` interface B` (the interface associated to the VXLAN isolation) is 1500 same as the other interface which is associated to the VLAN. Do you think the mtu size of 1500 is causing the problem. I tried configuring the mtu size of cloudbr1 to 1550, that seemed to have resolved the issue on the VM running on the same host as the virtual router, I was able to install Ubuntu there without any issues. Issues I am having right now: However, the issue right now is, the ubuntu installation process on the VM running on the other host is unable to connect to the internet and as a result is stuck at the curlin command. I find the behavior really weird and unexplainable as I am able to ping google.com and curl google.com from another VM with centos template running on the same host. **_Note:_** **I am using the same ISO to install Ubuntu on both the VMs. On the VM instance (associated to the host connected to the virtual router the installation process runs fine and updates from the internet as required). In the second VM (on a separate host) the installation process is unable to connect to the internet and gets stuck. Both the VMs are on the same network.** _Something I noticed that even though I didn't explicitly mention storage network, the storage network was added to `cloudbr0` along with the management network. This makes me wondering if that is causing any issue as the `cloudbr0` is connected to an access or untagged port on the switch. But it seems like cloudbr0 is being used for both the management and the storage network._ -- This is an automated message from the Apache Git Service.
