FreeBSD bhyve gains AMD SEV host stack with attestation for confidential VMs
↗
A complete AMD SEV host stack for FreeBSD’s bhyve hypervisor now enables confidential VMs with memory encryption and attestation
Confidential computing on FreeBSD moves from theory to practice, letting engineers deploy encrypted workloads without trusting the hypervisor. The addition of attestation closes a critical gap, proving the guest’s integrity before it runs sensitive code. This is a niche but meaningful step for teams already using FreeBSD in security-sensitive roles.

AMD SEV encrypts VM memory with a per-VM key hidden from the hypervisor
Attestation allows the guest owner to verify the exact code and configuration launched
The stack is implemented for FreeBSD’s bhyve hypervisor and is running today
