valid status check to allow the merge group to proceed.

cloud-hypervisor, ch-remote, vhost-user-block and vhost-user-net all
need at least one argument to do anything useful, so printing command
help is helpful when they are run without arguments or a subcommand.
Use clap::Command::arg_required_else_help(true) to do this.

Use clap::Command::subcommand_required(true) to yield a more friendly

To reduce issues caused by flaky tests split the musl and glibc jobs
into separate jobs. This means fewer jobs will need to be restarted for
flaky tests. This will also increase CI throughput since the musl builds
account for ~40% of the total CI time when run together with glibc.

When a guest running on a terminal reboots, the sigwinch_listener
subprocess exits and a new one restarts. The parent never wait()s
for children, so the old subprocess remains as a zombie. With further
reboots, more and more zombies build up.
As there are no other children for which we want the exit status,
the easiest fix is to take advantage of the implicit reaping specified
by POSIX when we set the disposition of SIGCHLD to SIG_IGN.
For this to work, we also need to set the correct default exit signal
of SIGCHLD when using clone3() CLONE_CLEAR_SIGHAND. Unlike the fallback
fork() path, clone_args::default() initialises the exit signal to zero,
which results in a child with non-standard reaping behaviour.

Allow cloud-hypervisor to direct boot the bzImage kernel format using

setup with the regular PVH boot code, but requires the setup of the

According to PCIe specification, a 64-bit MMIO BAR should be
naturally aligned. In addition to being more compliant with
the specification, natural aligned BARs are mapped with
the largest possible page size by the host iommu driver, which
should speed up boot time and reduce IOTLB thrashing for virtual
machines with VFIO devices.
