[libvirt] [PATCH 0/5] Fix starting of VMs with backing chains containing unknown backing file specification

When a backing chain element specifies a parent in a format not known to libvirt we'd fail to start the VM as the chain would appear broken. To prevent this happening introduce a new disk type to collect unknow format specs and avoid startup failures with such disk type. Peter Krempa (5): util: storage: Convert disk locality check to switch statement conf: Introduce raw disk string passthrough conf: Mark backing chain ending with "raw" volume as broken tests: Add tests for disk type 'raw' utils: storage: Fall back to "raw" disk on backing store parse failure docs/schemas/domaincommon.rng | 14 ++++ src/conf/domain_conf.c | 12 ++- src/qemu/qemu_command.c | 1 + src/qemu/qemu_driver.c | 4 + src/storage/storage_driver.c | 8 ++ src/util/virstoragefile.c | 35 +++++++- src/util/virstoragefile.h | 1 + .../qemuxml2argv-disk-backing-chains-raw.xml | 94 +++++++++++++++++++++ .../qemuxml2argv-disk-virtio-raw.args | 9 ++ .../qemuxml2argv-disk-virtio-raw.xml | 45 ++++++++++ tests/qemuxml2argvtest.c | 1 + ...muxml2xmlout-disk-backing-chains-raw-active.xml | 95 ++++++++++++++++++++++ ...xml2xmlout-disk-backing-chains-raw-inactive.xml | 59 ++++++++++++++ tests/qemuxml2xmltest.c | 2 + 14 files changed, 375 insertions(+), 5 deletions(-) create mode 100644 tests/qemuxml2argvdata/qemuxml2argv-disk-backing-chains-raw.xml create mode 100644 tests/qemuxml2argvdata/qemuxml2argv-disk-virtio-raw.args create mode 100644 tests/qemuxml2argvdata/qemuxml2argv-disk-virtio-raw.xml create mode 100644 tests/qemuxml2xmloutdata/qemuxml2xmlout-disk-backing-chains-raw-active.xml create mode 100644 tests/qemuxml2xmloutdata/qemuxml2xmlout-disk-backing-chains-raw-inactive.xml -- 2.0.2
