Subject: [PATCH qemu-server v7 0/2] hotplug: improve and fix cleanup/error handling
Date: Thu,  5 Nov 2026 09:22:13 +0100	[thread overview]
Message-ID: <20261105082524.428152-1-d.csapak@proxmox.com> (raw)

This replaces my earlier v4 9/9 patch[0]

It uses a different approach now by unifying the cleanup and removal of
disks and their controllers.

changes from v6:
* call print_drivedevice_full before adding the SCSI controller, so a
  volume rejected by the storage layer (e.g. a vanished storage) does
  not cause a controller plug/unplug cycle, and add a test for it
* add a test for a failed disk hotplug on a shared SCSI controller,
  which must keep the controller for the remaining disks

changes from v5:
* rebase on master
* rename helper to 'delete_disk_hardware'
* don't eval the individual calls, but always the whole function
  (drops noerr parameter)

changes from v4:
* rebase on master
* new bugfix (1/4)
* new patch for iothread deletion
* new patch for refactoring the cleanup
