It looks like we're not actually removing the use of -global, rather we're removing the driveA= and driveB= properties entirely, which simply means there's nothing to be set via -global. The distinction is important, because IIUC, it means that libvirt's use of these properties via -device is also impacted eg
-device isa-fdc,driveA=drive-fdc0-0-0,bootindexA=1,driveB=drive-fdc0-0-1
will no longer work too ?
Correct. This was deprecated in commit 4a27a638e7 "fdc: Deprecate configuring floppies with -global isa-fdc" (v5.1.0). Since then, its use triggers a warning: $ qemu-system-x86_64 -nodefaults -M q35 -display none -drive if=none,id=drive-fdc0-0-0 -device isa-fdc,driveA=drive-fdc0-0-0,bootindexA=1 qemu-system-x86_64: -device isa-fdc,driveA=drive-fdc0-0-0,bootindexA=1: warning: warning: property isa-fdc.driveA is deprecated Use -device floppy,unit=0,drive=... instead. Note the -M q35. Needed because the default machine type has an onboard isa-fdc, which cannot be configured this way. Sadly, the commit's update of docs/system/deprecated.rst neglects to cover this use. Looks the series overtaxed my capacity to juggle details; my apologies. Is libvirt still using these properties?
