Damd-memory-encryption.rst2 Secure Encrypted Virtualization (SEV)
8 Secure Encrypted Virtualization (SEV) is a feature found on AMD processors.
10 SEV is an extension to the AMD-V architecture which supports running
15 The hypervisor can determine the SEV support through the CPUID

25 If support for SEV is present, MSR 0xc001_0010 (MSR_AMD64_SYSCFG) and MSR 0xc001_0015
36 When SEV support is available, it can be enabled in a specific VM by
