From: Cleber Rosa Date: Mon, 12 Apr 2021 04:46:43 +0000 (-0400) Subject: Acceptance Tests: introduce CPU hotplug test X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=fd1ce58d901bbe982db8c19ca6e1a63b30643150;p=qemu.git Acceptance Tests: introduce CPU hotplug test Even though there are qtest based tests for hotplugging CPUs (from which this test took some inspiration from), this one adds checks from a Linux guest point of view. It should also serve as an example for tests that follow a similar pattern and need to interact with QEMU (via qmp) and with the Linux guest via SSH.
