From efd4d93b530807921b1940e13990c561530618d3 Mon Sep 17 00:00:00 2001 From: Jason Andryuk Date: Tue, 13 Oct 2020 10:05:11 -0400 Subject: [PATCH] accel: Add xen CpusAccel using dummy-cpus Xen was broken by commit 1583a3898853 ("cpus: extract out qtest-specific code to accel/qtest"). Xen relied on qemu_init_vcpu() calling qemu_dummy_start_vcpu() in the default case, but that was replaced by g_assert_not_reached(). Add a minimal "CpusAccel" for Xen using the dummy-cpus implementation used by qtest.
