domcaps: Check for architecture more wisely
https://bugzilla.redhat.com/show_bug.cgi?id=1209948 So we have this bug. The virConnectGetDomainCapabilities() API performs a couple of checks before it produces any result. One of the checks is if the architecture requested by user can be run by the binary (again user provided). However, the check is pretty dumb. It merely compares if the default binary architecture matches the one provided by user. However, a qemu binary can run multiple architectures. For instance: qemu-system-ppc64 can run: ppc, ppcle, ppc64, ppc64le and ppcemb. The default is ppc64, so if user requested something else, like ppc64le, the check would have failed without obvious reason.

LibVirt : simple API for virtualization Libvirt is a C toolkit to interact with the virtualization capabilities of recent versions of Linux (and other OSes). It is free software available under the GNU Lesser General Public License. Virtualization of the Linux Operating System means the ability to run multiple instances of Operating Systems concurrently on a single hardware system where the basic resources are driven by a Linux instance. The library aim at providing long term stable C API initially for the Xen paravirtualization but should be able to integrate other virtualization mechanisms if needed.

Description
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.
