Secure Encrypted Virtualization (SEV)

+ +

+ The contents of the <launch-security type=3D'sev'> element + is used to provide the guest owners input used for creating an encr= ypted + VM using the AMD SEV feature. + + SEV is an extension to the AMD-V architecture which supports running + encrypted virtual machine (VMs) under the control of KVM. Encrypted + VMs have their pages (code and data) secured such that only the gue= st + itself has access to the unencrypted version. Each encrypted VM is + associated with a unique encryption key; if its data is accessed to= a + different entity using a different key the encrypted guests data wi= ll + be incorrectly decrypted, leading to unintelligible data. + + For more information see various input parameters and its format se= e SEV API spec + https://support.amd.com/TechDocs/55766_SEV-KM%20API_Specifi= cation.pdf + Since 4.2.0 +

+
+ +

+ A least cbitpos and reduced-phys-bits must be + nested within the launch-security element. +

+
+
cbitpos
+
The cbitpos element provides the C-bit (aka encrypt= ion bit) + location in guest page table entry. The value of cbitpos is + hypervisor dependent and can be obtained through the sev element + from domaincapabilities. +
+
reduced-phys-bits
+
The reduced-phys-bits element provides the physical + address bit reducation. Similar to cbitpos the value of= + reduced-phys-bit is hypervisor dependent and can be obtained + through the sev element from domaincapabilities. +
+
policy
+
The optional policy element provides the guest poli= cy + which must be maintained by the SEV firmware. This policy is enforce= d by + the firmware and restricts what configuration and operational comman= ds + can be performed on this guest by the hypervisor. The guest policy + provided during guest launch is bound to the guest and cannot be cha= nged + throughout the lifetime of the guest. The policy is also transmitted + during snapshot and migration flows and enforced on the destination = platform. + + The guest policy is a 4-byte structure with the fields shown in Tabl= e: + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + +
Bit(s) Description
0 Debugging of the guest is disallowed when set
1 Sharing keys with other guests is disallowed when set
2 SEV-ES is required when set
3 Sending the guest to another platform is disallowed when se= t
4 The guest must not be transmitted to another platform that = is + not in the domain when set.
5 The guest must not be transmitted to another platform that = is + not SEV capable when set.
15:6 reserved
16:32 The guest must not be transmitted to another platform with a + lower firmware version.
+ Default value is 0x1 + +
+
dh-cert
+
The optional dh-cert element provides the guest own= ers public + Diffie-Hellman (DH) key. The key is used to negotiate a master secret + key between the SEV firmware and guest owner. This master secret key= is + then used to establish a trusted channel between SEV firmware and gu= est + owner. The value must be encoded in base64. +
+
session
+
The optional session element provides the guest own= ers + session blob defined in SEV API spec. The value must be encoded in b= ase64. + + See SEV spec LAUNCH_START section for session blob format. +
