1f0e5eb66a vmm: virtio-devices: Restore every VirtioDevice upon creation 
Following the new design proposal to improve the restore codepath when
migrating a VM, all virtio devices are supplied with an optional state
they can use to restore from. The restore() implementation every device
was providing has been removed in order to prevent from going through
the restoration twice.

Here is the list of devices now following the new restore design:

- Block (virtio-block)
- Net (virtio-net)
- Rng (virtio-rng)
- Fs (vhost-user-fs)
- Blk (vhost-user-block)
- Net (vhost-user-net)
- Pmem (virtio-pmem)
- Vsock (virtio-vsock)
- Mem (virtio-mem)
- Balloon (virtio-balloon)
- Watchdog (virtio-watchdog)
- Vdpa (vDPA)
- Console (virtio-console)
- Iommu (virtio-iommu)

7b31871a36 fuzz: mem: Avoid using hugepages 
The kernel will trigger a SIGBUS upon hugetlb page faults when there is
no huge pages available. We neither have a way to ensure enough huge
pages available on the host system, nor have a way to gracefully report
the lack of huge pages in advance from Cloud Hypervisor. For these
reasons, we have to avoid using huge pages from the virtio-mem fuzzer to
avoid SIGBUS errors.

4fea40f008 fuzz: Balloon: Reduce the guest memory size and queue size 
With the guest memory size of 1MB, a valid descriptor size can be close
to the guest memory size (e.g. 1MB) and can contain close to 256k
valid pfn entries (each entry is 4 bytes). Multiplying the queue
size (e.g. 256), there can be close to 64 millions pfn entries to
process in a single request. This is why the oss-fuzz reported a
timeout (with a limit of 60s).

By reducing the guest memory size and the queue size, the worst-case now
is 8 million pfn entries for fuzzing, which can be finished in around 20
seconds according to my local experiment.

ef603fde4c fuzz: Reduce the guest memory size for balloon fuzzer 
As the virt queues are initialized with random bytes from the fuzzing
engine, a descriptor buffer for the available ring can have a very large
length (e.g. up to 4GB). This means there can be up to 1 billion
entries (e.g. page frame number) for virtio-balloon to process a signal
available descriptor (given each entry is 4 bytes). This is the reason
why oss-fuzz reported a hanging issue for this fuzzer, where the
generated descriptor buffer length is 4,278,321,152.

We can avoid this kind of long execution by reducing the size of guest
memory. For example, with 1MB of guest memory, the number of descriptor
entries for processing is limited ~256K.

e1b483fc88 fuzz: Add fuzzer for virtio-rng 
To make the fuzzer faster and more effective, the guest memory is
setup with a much smaller size (comparing with other virtio device
fuzzers) and  a hole between the memory for holding virtio queue and
the rest of guest data. It brings two benefits: 1) avoid writing large
chunk of data from 'urandom' into the available descriptor chain (which
makes the fuzzer faster); 2) reduce substantial amount of overwrites to
the virtio queue data by the data from 'urandom (which makes the fuzzer
more deterministic and hence effective).

742d6858f7 fuzz: block: Setup the virt queue based on the fuzzed input bytes 
Instead of always fuzzing virt-queues with default values (mostly 0s),
the fuzzer now initializes the virt-queue based on the fuzzed input
bytes, such as the tail position of the available ring, queue size
selected by driver, descriptor table address, available ring address,
used ring address, etc. In this way, the fuzzer can explore the
virtio-block code path with various virt-queue setup.

0b182be65e fuzz: block: Remove meaningless setup to the virt-queue 
The current fuzzer defines a 'format' for the random input 'bytes' from
libfuzzer, but this 'format' failed to improve the fuzzing
efficiency. Instead, the 'format' parsing process obfuscates the fuzzer and
makes the fuzzing engine much harder to focus on the actual fuzzing
target (e.g. virtio-block queue event handling). It is actually worse than
simply using the random inputs as the virt queue content for fuzzing.

We can later introduce a different 'format' to the input 'bytes' for
better fuzzing, say focusing more on virito-block fuzzing through
ensuring the virt queue content always has a valid 'available'
descriptor chain to process.

fbec4a070d fuzz: block: Ensure the virtio-block thread is killed and joined 
This also ensures that the 'queue_evt' is fully processed, as we enforce
the main thread is waiting for the virtio-block thread to process the
'kill_evt' which is after the 'queue_evt' processing.

5ba3b80e83 fuzz: block: Ensure a queue event is properly processed 
Currently the main thread returns immediately after sending a 'queue'
event which is rarely received and processed by the virtio-block
thread (unless system is in high workload). In this way, the fuzzer is
mostly doing nothing and is unable to reproduce its behavior
deterministically (from the same inputs). This patch relies on a
'level-triggered' epoll to ensure a 'queue' event is properly processed
before return from the main thread.
