Subject: [PATCH 3/5] vhost-user-blk: Get more feature flags from vhost device
Date: Thu, 22 Apr 2021 19:02:19 +0200	[thread overview]
Message-ID: <20210422170221.285006-4-kwolf@redhat.com> (raw)
In-Reply-To: <20210422170221.285006-1-kwolf@redhat.com>

VIRTIO_F_RING_PACKED and VIRTIO_F_IOMMU_PLATFORM need to be supported by
the vhost device, otherwise advertising it to the guest doesn't result
in a working configuration. They are currently not supported by the
vhost-user-blk export in QEMU.

Fixes: https://bugzilla.redhat.com/show_bug.cgi?id=1935020
