[pve-devel] [PATCH 00/11] Refactor QemuServer to avoid dependency cycles

[Stefan Reiter]

First 3 patches are independant refactorings around get_host_arch.

Rest of the series refactors QemuServer and creates three new packages:
* 'PVE::QemuSchema' for schema related code and common directory creation
* 'PVE::QMP' for higher-level QMP functions
* 'PVE::QemuServer::Machine' for QEMU machine-type related helpers

This refactoring came along because qemu_machine_feature_enabled needs to be
used in 'PVE::QemuServer::CPUConfig', a new package that will be introduced with
my custom CPU series [0]. This would currently require dependency cycles, but by
extracting the code in this series and splitting it up into multiple helper
modules, this can be avoided.

Care was taken not to introduce new dependecy cycles, though this required to
move the 'check_running' function to QemuConfig.pm, where it doesn't *quite* fit
IMO, but I also didn't want to create a new module just for this one function.
Open for ideas ofc.
