Under high load, the VM might take some time to hotplug the disk after
the hotplug command has been issued. For this reason, let's put a 10s
sleep before checking for the presence of the new disk.

We want to give the time to the nested VM to be fully ready before we
check it's correctly setup. This involves 3 layers of virtualization
when running the CI on Azure, which added to the high load happening
because of the parallelization, adds up to the start up time.

The virtio configuration structures have been slightly modified between
5.6-rc4 and 5.8-rc4, forcing the virtio-iommu device to be updated
accordingly.

Updating the kernel from 5.6-rc4 to 5.8-rc4 allows us to remove the
dependency on both virtio-vsock and virtio-mem patches as they are now
part of the upstream kernel. We're still carrying virtio-iommu and
virtio-fs patches.

Move the definition of RawFile from virtio-devices crate into qcow
crate. All the code that consumes RawFile also already depends on the
qcow crate for image file type detection so this change breaks the
need for the qcow crate to depend on the very large virtio-devices
crate.

Move NetQueuePair and the related NetCounters into the net_util crate.
This means that the vhost_user_net crate now no longer depends on
virtio-devices and so does not depend on the pci, qcow or other similar
crates. This significantly simplifies the build chain for this backend.

By moving the code for opening the two RX and TX queues into a shared

itself depends on many other crates that are not necessary for the
backend to function.

This commit store balloon size to MemoryConfig.
After reboot, virtio-balloon can use this size to inflate back to
the size before reboot.
Signed-off-by: Hui Zhu <teawater@antfin.com>
The implementation of the virtio-balloon was slightly wrong as it was
generating the GPA (Guest Physical Address) from the PFN (Page Frame
Number) which was a u32. That means the GPA was created as a u32, and
later a cast was done to extend it to a u64 type. Unfortunately, by
doing so, the GPA was wrong if the value was supposedly more than 32
bits.
That's why the PFN is casted into a u64 before the GPA is generated,
which creates the GPA on 64 bits directly.
Additionally, this patch simplifies the process_queue() function,
relying on multiple vm-memory helpers.

This commit adds supporting components and code for enabling the

Remove the vmm dependency from vhost_user_block and vhost_user_net where
it was existing to use config::OptionParser. By moving the OptionParser
to its own crate at the top-level we can remove the very heavy

In order to move the hypervisor specific parts of the VM exit handling
path, we're defining a generic, hypervisor agnostic VM exit enum.
This is what the hypervisor's Vcpu run() call should return when the VM
exit can not be completely handled through the hypervisor specific bits.
For KVM based hypervisors, this means directly forwarding the IO related
exits back to the VMM itself. For other hypervisors that e.g. rely on the
VMM to decode and emulate instructions, this means the decoding itself
would happen in the hypervisor crate exclusively, and the rest of the VM
exit handling would be handled through the VMM device model implementation.
