qemu-system-FOO's main() acts on command line arguments in its own
|
|
idiosyncratic order. There's not much method to its madness.
|
|
Whenever we find a case where one kind of command line argument needs
|
|
to refer to something created for another kind later, we rejigger the
|
|
order.
|
|
|
|
Recent commit cda4aa9a5a "vl: Create block backends before setting
|
|
machine properties" was such a rejigger. Block backends are now
|
|
created before "delayed" objects. This broke persistent reservation
|
|
management. Reproducer:
|
|
|
|
$ qemu-system-x86_64 -object pr-manager-helper,id=pr-helper0,path=/tmp/pr-helper0.sock-drive -drive file=/dev/mapper/crypt,file.pr-manager=pr-helper0,format=raw,if=none,id=drive-scsi0-0-0-2
|
|
qemu-system-x86_64: -drive file=/dev/mapper/crypt,file.pr-manager=pr-helper0,format=raw,if=none,id=drive-scsi0-0-0-2: No persistent reservation manager with id 'pr-helper0'
|
|
|
|
The delayed pr-manager-helper object is created too late for use by
|
|
-drive or -blockdev. Normal objects are still created in time.
|
|
|
|
pr-manager-helper has always been a delayed object (commit 7c9e527659
|
|
"scsi, file-posix: add support for persistent reservation
|
|
management"). Turns out there's no real reason for that. Make it a
|
|
normal object.
