Subject: [PATCH 1/6] Revert "netdev: set timeout depending on loadavg"
Date: Thu,  4 Jan 2024 16:29:37 +0000	[thread overview]
Message-ID: <20240104162942.211458-2-berrange@redhat.com> (raw)
In-Reply-To: <20240104162942.211458-1-berrange@redhat.com>

This reverts commit cadfc7293977ecadc2d6c48d7cffc553ed2f85f1.

The test was not timing out because of slow execution. It was
timing out due to a race condition leading to the client QEMU
attempting (and fatally failing) to connect before the server
QEMU was listening.
