This is for example useful in the migration if we don't want to rely on the scanning of all storages. All calling sites are adapted and enable it, except for QemuConfig::get_replicatable_volumes as that would cause a change for the replication if pending disks would be included. The following lists the calling sites and if they should be fine with the change (source [0]): 1. QemuMigrate: scan_local_volumes(): needed to include pending disk images 2. API2/Qemu.pm: check_vm_disks_local() for migration precondition: related to migration, so more consistent with pending 3. QemuConfig.pm: get_replicatable_volumes(): would change the behavior of the replication, will not use it for now. 4. QemuServer.pm: get_vm_volumes(): is used multiple times by: 4a. vm_stop_cleanup() to deactivate/unmap: should also be fine with including pending 4b. QemuMigrate.pm: in prepare(): part of migration, so more consistent with pending 4c. QemuMigrate.pm: in phase3_cleanup() for deactivation: part of migration, so more consistent with pending [0] https://lists.proxmox.com/pipermail/pve-devel/2023-May/056868.html Signed-off-by: Aaron Lauterer --- changes since v4: - reodered - only change QemuServer::foreach_volid and not Storage::foreach_volid I kept the if condition and following function call as is, since this is just an intermediate patch and readability is a bit nicer this way.
