https://bugzilla.redhat.com/show_bug.cgi?id=1405269 If a secret was not provided for what was determined to be a LUKS encrypted disk (during virStorageFileGetMetadata processing when called from qemuDomainDetermineDiskChain as a result of hotplug attach qemuDomainAttachDeviceDiskLive), then do not attempt to look it up (avoiding a libvirtd crash) and do not alter the format to "luks" when adding the disk; otherwise, the device_add would fail with a message such as: "unable to execute QEMU command 'device_add': Property 'scsi-hd.drive' can't find value 'drive-scsi0-0-0-0'" because of assumptions that when the format=luks that libvirt would have provided the secret to decrypt the volume. Access to unlock the volume will thus be left to the application.
LibVirt : simple API for virtualization
Libvirt is a C toolkit to interact with the virtualization capabilities
of recent versions of Linux (and other OSes). It is free software
available under the GNU Lesser General Public License. Virtualization of
the Linux Operating System means the ability to run multiple instances of
Operating Systems concurrently on a single hardware system where the basic
resources are driven by a Linux instance. The library aim at providing
long term stable C API initially for the Xen paravirtualization but
should be able to integrate other virtualization mechanisms if needed.
