Package: openstack-cluster-installer-poc Version: 21 Severity: normal qemu package is a dummy metapackage which has no actual reason to exist. Qemu provides 2 entirely different modes of operations, it is a system-level emulation, where qemu emulates whole (hardware) system with its own CPU, memory subsystem, peripherial devices, BIOS/firmware etc. This is qemu-system, or, with hardware assistance, qemu-kvm. And another mode, where it can run linux programs built for different architecture on another linux system, for example to run arm linux binaries on an x86 linux. This is qemu-user and variations.
As far as I can see, openstack-cluster-installer-poc wants with the system-mode emulation of qemu, not the user-mode. So depending on the actual usage, you might want to depend on either whole qemu-system, or individual qemu-system-XXX (with XXX being arm, misc, mips, ppc, sparc, s390x and x86), maybe the best is to list all of them as alternatives. Or, if you actually want the native hardware-assisted virtualization, depend on qemu-kvm which is a virtual package provided by one of the qemu-system-XXX packages (native for the architecture, not available on all architectures). The goal is to remove `qemu' binary metapackage from Debian, because this package is not right, it is pulling whole qemu with all its modes of operations, - this is not what most people actually want, due to what's been said above.
