In my previous commit v10.10.0-48-g2d222ecf6e I've made us enable I/O APIC when there is an IOMMU with EIM. This works well. What does not work is case when there's just an IOMMU without EIM but with 256+ vCPUS. Problem is that post parsing happens in two stages: general domain post parse (where qemuDomainDefEnableDefaultFeatures() is called) and then per device post parse (where qemuDomainIOMMUDefPostParse() is called). Now, in aforementioned case it is the device post parse phase where EIM is enabled but the code that would enable VIR_DOMAIN_FEATURE_IOAPIC has already run. To resolve this, make the domain post parse callback "foresee" the future enabling of EIM so that it can turn on I/O APIC beforehand.

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.
