The vhost-user protocol requires 64-bit device features, but the virtio spec allows 128. This commit truncates features to 64 bits before sending, fixing a bug where all 128 bits were sent, causing feature negotiation to fail. Fixes: 128153e ("fix(virtio): extend virtio feature to 128 bits") Signed-off-by: Changyuan Lyu <changyuanl@google.com>
A VirtIO device generally needs exclusive access to specific resources on the host. Creating multiple devices from the same config to serve multiple VMs simultaneously could lead to resource contention. Especially, commit de79b5f made device creation ahead of connection acceptance, and failed virtio-net devices, because when 1 virtio-net device is running, another virtio-net device is created, and the latter opens the same tap again, interfering with the first device's IO.
