51306555e7 vmm: Add hugetlbfs handling support
The currently directory handling process to open tempfile by
OpenOptions with custom_flags(O_TMPFILE) is workable for tmp
filesystem, but not workable for hugetlbfs, add new directory
handling process which works fine for both tmpfs and hugetlbfs.

b2f85cbdc4 vhost_rs: Wait for full request to be satisfied
The recvmsg syscall can split a request in multiple packets unless we
use the flag MSG_WAITALL to make sure the request will wait for the
whole data to be transferred before returning.

This flag is needed to prevent the vhost crate from returning the error
PartialMessage, which occured sporadically when using virtio-fs, and
which was detected as part of our continuous integration testing.

Fixes #182

0b8856d148 vmm: Add RwLock to the GuestMemoryMmap
Following the refactoring of the code allowing multiple threads to
access the same instance of the guest memory, this patch goes one step
further by adding RwLock to it. This anticipates the future need for
being able to modify the content of the guest memory at runtime.

The reasons for adding regions to an existing guest memory could be:
- Add virtio-pmem and virtio-fs regions after the guest memory was
  created.
- Support future hotplug of devices, memory, or anything that would
  require more memory at runtime.

Because most of the time, the lock will be taken as read only, using
RwLock instead of Mutex is the right approach.

ec0b5567c8 vmm: Share the guest memory instead of cloning it
The VMM guest memory was cloned (copied) everywhere the code needed to
have ownership of it. In order to clean the code, and in anticipation
for future support of modifying this guest memory instance at runtime,
it is important that every part of the code share the same instance.

Because VirtioDevice implementations need to have access to it from
different threads, that's why Arc must be used in this case.

f4d41d600b virtio: net: Remove TAP fd from epoll when no available descriptors
When there are no available descriptors in the queue (observed when the
network interface hasn't been brought up by the kernel) stop waiting for
notifications that the TAP fd should be read from.

This avoids a situation where the TAP device has data avaiable and wakes
up the virtio-net thread only for the virtio-net thread not read that
data as it has nowhere to put it.

When there are descriptors available in the queue then we resume waiting
for the epoll event on the TAP fd.

This bug demonstrated itself as 100% CPU usage for cloud-hypervisor
binary prior to the guest network interface being brought up. The
solution was inspired by the Firecracker virtio-net code.

dc31db478a ci: Fix virtio-fs tests
The virtiofsd daemon takes a bit of time creating and listening on the
socket. By adding 10s timeout, we make sure the vhost-user socket has
been properly created before the VMM tries to connect to it.

Also, the daemon needs cap_dac_override capabilities to access debugfs
filesystem.

Last thing, both virtio-fs and virtio-pmem tests were slightly different
from the others since they were not explicitly killing cloud-hypervisor
and virtiofsd processes once the test was done.

where dax=on and dax=off.

In order to support DAX, the kernel configuration needs to be updated to
include CONFIG_FS_DAX and CONFIG_ZONE_DEVICE.
