Some default features of the pseries machine are only available with KVM. Warnings are printed when the pseries machine is used with another accelerator: qemu-system-ppc64: warning: TCG doesn't support requested feature, cap-ccf-assist=on qemu-system-ppc64: warning: Firmware Assisted Non-Maskable Interrupts(FWNMI) not supported in TCG qemu-system-ppc64: warning: TCG doesn't support requested feature, cap-ccf-assist=on qemu-system-ppc64: warning: Firmware Assisted Non-Maskable Interrupts(FWNMI) not supported in TCG qemu-system-ppc64: warning: TCG doesn't support requested feature, cap-ccf-assist=on qemu-system-ppc64: warning: Firmware Assisted Non-Maskable Interrupts(FWNMI) not supported in TCG This is annoying for CI since it usually runs without KVM. We already disable features that emit similar warnings thanks to properties of the pseries machine, but this is open-coded in various places. Consolidate the set of properties in a single place. Extend it to silence the above warnings. And use it in the various tests that start pseries machines.
