Hi Team,

QEMU uses GnuTLS for TLS migration, while Intel QAT TLS acceleration is available via OpenSSL engine/provider.

Is there any supported way to enable QAT acceleration for migration TLS today, or does this require modifying QEMU to use OpenSSL instead of GnuTLS?

Yeah, QEMU needs to be changed so that it can support openssl. Though, in case of tunneled migration [1] it's actually libvirt that transfers data onto the destination and it too uses gnutls. Michal 1: https://libvirt.org/migration.html#libvirt-tunnelled-transport
