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? ^ permalink raw reply [flat|nested] 13+ messages in thread

Unfortunately yes, but it seems like it ought to be fairly easy to change the syntax. Just need to figure out what the right way to detect the availability of the new syntax is. Presumably just look for existance of the 'floppy' device type ? Can you confirm that switching from -global to the new -device floppy does /not/ have any live migration impact ?

Yes, it must not affect migration. When Kevin split the floppy device type off the floppy controller, he had to add some moderately ugly hackery to keep the old qdev properties working. Think propagate property values to floppy from controller, which otherwise ignores them. The way you get the values into the floppy device cannot affect the migration data. Only different values can. This patch removes a deprecated way. ^ permalink raw reply [flat|nested] 13+ messages in thread

Note that when QEMU_CAPS_BLOCKDEV is asserted we format floppies as: -blockdev '{"driver":"file","filename":"/tmp/firmware.img",\ "node-name":"libvirt-2-storage","auto-read-only":true,"discard":"unmap"}' \ -blockdev '{"node-name":"libvirt-2-format","read-only":false,"driver":"raw",\ "file":"libvirt-2-storage"}' \ -device floppy,unit=0,drive=libvirt-2-format,id=fdc0-0-0 \ -blockdev '{"driver":"file","filename":"/tmp/data.img",\ "node-name":"libvirt-1-storage","auto-read-only":true,"discard":"unmap"}' \ -blockdev '{"node-name":"libvirt-1-format","read-only":false,"driver":"qcow2",\ "file":"libvirt-1-storage"}' \ -device floppy,unit=1,drive=libvirt-1-format,id=fdc0-0-1 \ as visible in the test file: tests/qemuxml2argvdata/disk-floppy-q35-2_11.x86_64-latest.args So libvirt should be in the clear. isa-fdc with driveA/driveB is formatted only when the blockdev capability isn't present. ^ permalink raw reply [flat|nested] 13+ messages in thread

Even better: in the clear for some time already, which means a wider range of libvirt versions keeps working with the latest QEMU. Nice, because keeping the coupling reasonably lose makes upgrading easier. Thanks! ^ permalink raw reply [flat|nested] 13+ messages in thread

Looks the series overtaxed my capacity to juggle > details; my apologies. [...] I'm talking about commit 4a27a638e7 here. The deprecated.rst text only covers setting floppy controller properties with -global. It neglects to cover setting them with -device. For onboard controllers, -global is the only way to set them. I append a fixup. We can put it before this patch. This patch then moves the fixed up text to removed-features.rst. Or we squash it into this patch, i.e. this patch deletes the flawed text from deprecated.rst and adds the fixed up text to removed-features.rst.

I'm fine with either option. It isn't unusual to tweak the text when moving it to the removed-features.rst file, as we'll be talking about the past rather than future.
