[PATCH-SERIES qemu-server 0/3] ovmf: create temporary EFI disk below /run instead of /tmp to avoid migration issue

[Fiona Ebner <f.ebner@proxmox.com>]

As reported in the enterprise support, QEMU might fail to inactivate
the block node for the temporary EFI disk during migration:

> kvm: migration_block_inactivate: bdrv_inactivate_all() failed: -1
> kvm: Error in migration completion: Bad address

The issue occurs when the file for the temporary EFI disk has been
removed from the file system. This happens on new installations since
Debian Trixie [0], where files in /tmp are regularly cleaned.

qemu-server:

Fiona Ebner (3):
  d/tmpfiles: add configuration to auto-create /run/qemu-server
    directory
  ovmf: use file module directly for file_copy()
  ovmf: create temporary EFI disk below /run instead of /tmp to avoid
    migration issue
