[Qemu-devel] [PULL 15/41] vl: Fix broken thread=xxx option of the --acce


From: Paolo Bonzini
Subject: [Qemu-devel] [PULL 15/41] vl: Fix broken thread=xxx option of the --accel parameter
Date: Thu, 15 Jun 2017 12:52:35 +0200

From: Thomas Huth <address@hidden>

Commit bde4d9205 ("Fix the -accel parameter and the documentation for
'hax'") introduced a regression by adding a new local accel_opts
variable which shadows the variable with the same name that is
declared at the beginning of the main() scope. This causes the
qemu_tcg_configure() call later to be always called with NULL, so
that the thread=xxx option gets ignored. Fix it by removing the
local accel_opts variable and use "opts" instead, which is meant
for storing temporary QemuOpts values.
And while we're at it, also change the exit(1) here to exit(0)
since asking for help is not an error.
