[PATCH] Documentation: KVM: Synchronize x86 VM types

From: Carlos López

Date: Wed Jun 03 2026 - 07:52:15 EST


KVM has reflected KVM_X86_SNP_VM to userspace since 1dfe571c12cf
("KVM: SEV: Add initial SEV-SNP support"), and KVM_X86_TDX_VM since
161d34609f9b ("KVM: TDX: Make TDX VM type supported"). Update the
documentation to reflect this fact.

Fixes: 1dfe571c12cf ("KVM: SEV: Add initial SEV-SNP support")
Fixes: 161d34609f9b ("KVM: TDX: Make TDX VM type supported")
