Subject: [PATCH v3 10/11] Acceptance Tests: introduce CPU hotplug test
Date: Mon, 12 Apr 2021 00:46:43 -0400 [thread overview]
Message-ID: <20210412044644.55083-11-crosa@redhat.com> (raw)
In-Reply-To: <20210412044644.55083-1-crosa@redhat.com>
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.
