A Quick Intro to vCloud Air Hybrid Cloud Manager

I wanted to give you a quick-read introduction of vCloud Hybrid cloud manager.

vCloud Air Hybrid Cloud Manager enables bidirectional VM mobility and migration to the cloud and back, and hybrid networking to extend on-premises vSphere vCenter networks into vCloud Air. Data transport features include network extension, WAN optimization, Multi-tenant WAN with Intelligent Routing, and path fail-over.

Security features include Suite B-compliant AES-GCM with IKEv2, data de-duplication and compression, AES-NI Offload, Flowbased Admission Control. It gets interesting because Hybrid Cloud Manager owns the source and destination encryption and decryption, ensuring a consistent security policy and providing admission for hybrid workflows like virtual machine migration and network extension.

These features can be deployed in several ways. Hybrid Networking (Layer 2 Extension) can securely extend your vSphere vCenter to integrate with a vCloud Air Virtual Data Center (vDC). We can also stretch multiple L2 segments  and can route stretched networks via Cloud Gateway for encryption and through the WAN optimization appliance to provide a secure and optimized path through the Internet to vCloud Air.

Nested ESXi Lab in VMware vCloud Air

The vCloud Air 200$ signup credits was nice because it helped me play with the On-demand virtual private cloud subscription. vCloud air is quite powerful and the UI is quite responsive. The waiting times increase when you use the vCloud Director UI because of the automation hooks in the back that need to get updated.

One thing I tried to do is deploy an ESXi ISO in my catalog and tried to deploy a nested hypervisor. This however failed because VT was not enabled in the virtual machine BIOS.

I tried my best to access the BIOS but I just couldn’t. So how do we get vCloud air to deploy a nested hypervisor and build a lab? Simple deploy a prebuilt appliance 🙂

I used my VMware Fusion and built a virtual machine (no OS) with VT enabled in the BIOS. I exported it as a OVA and imported that to my vCloud Air catalog. I then attached the ESXi ISO from my ISO catalog and viola! – nested ESXi hypervisor in vCloud Air.

For your convenience I have the OVA attached here. Just download and upload it to your vCloud Air catalog –> attach the ESXi OVA –> Power on and install and deploy nested VMs!

vCloud Air vApp Networking “Pending” Status – Bug!

Been busy but I tried to squeeze out sometime to play with VMware’s vCloud Air On-Demand. If you been to the VMUG UserCon’s then you would know that VMware was giving away 200$ worth of free vCloud Air usage to test out the product.

I deployed a virtual machine – well actually I uploaded it to my Catalog and deployed it from there. I made sure i added it to the default routed network – which you get assigned by default. It is a /24 subnet that you get for your account.

Although my VM was on it – in the “networking” tab you see a “Pending” Status as shown in the below pic. This tab is part of the vCloud Director console so you will only see it when you manage your environment using vCloud Director.


VMware vCloud Air support today confirmed that this was a bug with vCloud Director and that it has no affect on network connectivity.

I wanted to make sure you were aware of this so you don’t freak out like I did 🙂
