Laura Hild c4d96fdd3c Don't set cur=inf RLIM_NOFILE on macOS
virProcessActivateMaxFiles sets rlim_cur to rlim_max.
If rlim_max is RLIM_INFINITY,

2023-08-15 15:17:51.944+0000: 4456752640: debug :
virProcessActivateMaxFiles:1067 : Initial max files was 2560
2023-08-15 15:17:51.944+0000: 4456752640: debug :
virProcessActivateMaxFiles:1077 : Raised max files to
9223372036854775807

then when virCommandMassClose does `int openmax = sysconf(
_SC_OPEN_MAX)`, `openmax < 0` is true and virCommandMassClose
reports an error and bails.  Setting rlim_cur instead to at most
OPEN_MAX, as macOS' documentation suggests, both avoids this problem

2023-08-18 16:01:44.366+0000: 4359562752: debug :
virProcessActivateMaxFiles:1072 : Initial max files was 256
2023-08-18 16:01:44.366+0000: 4359562752: debug :
virProcessActivateMaxFiles:1086 : Raised max files to 10240

and eliminates a case of what the documentation declares
to be invalid input to setrlimit anyway.

Libvirt API for virtualization

Libvirt provides a portable, long term stable C API for managing the virtualization technologies provided by many operating systems. It includes support for QEMU, KVM, Xen, LXC, bhyve, Virtuozzo, VMware vCenter and ESX, VMware Desktop, Hyper-V, VirtualBox and the POWER Hypervisor.

For some of these hypervisors, it provides a stateful management daemon which runs on the virtualization host allowing access to the API both by non-privileged local users and remote users.

Layered packages provide bindings of the libvirt C API into other languages including Python, Perl, PHP, Go, Java, OCaml, as well as mappings into object systems such as GObject, CIM and SNMP.
