Both VM Home files (VMX, snapshot, etc) and VMDK files are encrypted. As I/O comes out of the virtual disk controller in the VM it is immediately encrypted by a module in the kernel before being send to the kernel storage layer. With vSphere 6.5 we are addressing that head on.Įncryption will be done in the hypervisor, “beneath” the virtual machine. But, in case you hadn’t noticed, it just hasn’t “taken off” because every solution has a negative operational impact. VM EncryptionĮncryption of virtual machines is something that’s been on-going for years. The key to security at scale is automation and in these new features you’ll see plenty of that. She/He doesn’t have the resources to do that. Managing 100’s or 1000’s of security “snowflakes” is something no IT manager wants to do. Security in a virtual infrastructure must be able to be done “at scale”. If security is not easy to implement and manage then the benefit it may bring is offset. Security has become a front and center focus of this release and I think you’ll like what we’ve come up with. What was mostly an afterthought by many IT folks only a few short years ago is now one of the top drivers of innovation for vSphere. VSphere 6.5 is a turning point in VMware infrastructure security.
