Subject: [Qemu-devel] [PATCH 0/2] virtio-rng: fix old guest kernel hang
Date: Wed, 27 Jun 2018 13:52:46 +0530 [thread overview]
Message-ID: <20180627082248.14921-1-pagupta@redhat.com> (raw)
virtio-rng device causing old guest kernels(2.6.32) to hang on latest qemu.
The driver attempts to read from the virtio-rng device too early in it's
initialization. Qemu detects guest is not ready and returns, resulting in
hang. Below patches fix this.
