DESCRIPTION:Confidential computing is a family of techniques to enhance sec
 urity\nand confidentiality for data in use.  One technical approach is str
 ong\nisolation for virtual machines.\n\nAMDs Secure Encrypted Virtualizati
 on (SEV) offers several feature sets\nfor isolation of guest virtual machi
 nes from an non-trusted host hypervisor\nand operating system.  These feat
 ure sets include memory encryption\,\nencryption of guest state including 
 CPU registers and an attestation\nframework.\n\nIn this talk we will explo
 re some of the AMD SEV feature sets.  We will\ndescribe how to use them to
  run OpenBSD as both\n\n - a confidential guest VM and\n - a host hypervis
 or providing a confidential execution environment.\n\nTopics covered are C
 PU feature detection\, low level kernel initialization\,\nmemory managemen
 t\, virtio(4) device drivers and the virtual machine\ndaemon vmd(8).
