[PATCH v3 0/5] qemu: Introduce shared_filesystems configuration option

The need to have something like this in the first place is driven by KubeVirt (see [1] and [2]). A draft version of this series has been integrated into KubeVirt and it has been confirmed that it was effective in removing the need to use LD_PRELOAD hacks in the storage provider. Changes from [v2]: * added canonicalization for user-provided paths; * fixed compilation issues when AppArmor support is enabled. Changes from [v1]: * documented more explicitly that the newly introduced option is intended for very specific scenarios and not general usage; as part of this, the NEWS update has been dropped too; * made a few tweaks and addressed a few oversight based on review feedback; * several preparatory cleanup patches have been pushed. Changes from [v0]: * reworked approach. [v2] https://lists.libvirt.org/archives/list/devel@lists.libvirt.org/thread/XP...
