[Qemu-devel] [PULL 16/25] accel: Allow to build QEMU without TCG or KVM support

Posted by Paolo Bonzini 6 years, 8 months ago

From: Anthony PERARD <anthony.perard@citrix.com>

Instead of deny build of QEMU without a default accelerator, simply
report an error when the user haven't passed -accel or -machine accel=
and TCG and KVM isn't builtin.

./configure already check that at least one accelerator is available.
