Subject: [PATCH] target/i386: sev: do not create launch context for an
|
|
incoming guest
|
|
|
|
cherry-picked from https://github.com/AMDESE/qemu/commit/b85694233495.
|
|
|
|
The LAUNCH_START is used for creating an encryption context to encrypt
|
|
newly created guest, for an incoming guest the RECEIVE_START should be
|
|
used.
