vSphere 6.5 Security Encrypted vMotion
Interesting
Encrypted vMotion has been asked about for YEARS. It’s here now in vSphere 6.5! And, like VM Encryption, we’ve taken a different approach than you might think. We don’t actually encrypt the vMotion network. What we DO encrypt is the data going over the vMotion network. At the time of migration, a 256-bit key and 64-bit Nonce are created by vCenter. This is a one-time-use key and is not persisted!
Some thoughts:
- what is the impact of the encryption on vMotion performance, especially at load ? Since its symmetric encryption (OTP Key would suggest that) it should light on CPU but still.
- Joined up thinking between network and vm admins is key here. If the network already encrypts this would be silly to implement so “The best part is you don’t have to ask your network team to do anything!” would be doubling down on stupid.
- Network encryption should lower latency (hardware acceleration) and perform better (remember, don’t ask your network team anything)
- Security is a top down thing. If you are bothering to encrypt at all, everything should be encrypted not just the vMotion. Thats kind of pointless if all other data is in the clear.

I would expect nothing less from a Cisco CLI to be fair. Irrational, inconsistent and byzantine CLI is the normal.

Why IT Automation is Becoming a Business Necessity
Automation transformed factories. It gave manufacturing the ability to perform work faster, more efficiently, at higher quality. Processes became predictable. Productivity thrived. Factories that failed to automate fell behind. Automation became a business imperative.
IT departments are the modern factories powering today’s digital businesses. And just as today’s factories can’t compete without automation, automation will soon become imperative for IT organizations. Here’s why:
- Application delivery is fuel for growth. Today every business is a software business, regardless of whether you actually sell software. Every business depends on critical systems to engage with customers and gather data. For companies competing in the knowledge economy, IT operations is oxygen. The demands businesses place on DevOps teams will only continue to increase. We’re not going back—only forward, faster.
- Automation simplifies processes. Automation never sleeps. Throwing people at the problem helps companies grow, but the law of diminishing returns limits your ability to scale. Adding people adds complexity and costs.
- IT professionals don’t want to repeat the same tasks over and over. Just as manual work in factories is tiring, endless, and thankless—repetitive work squanders the creative energy of your best and often most highly paid people.
- Automation speeds the work so your people Continue reading
