QEMU uses curl for accessing files using http(s) and ftp(s). They share common options so let's generate them in one helper.

Libvirt historically stores storage source path including the volume as one string in the XML, but that is not really flexible enough when dealing with the fields in the code. Previously we'd store the slash separating the two as part of the image name. This was fine for gluster but it's not necessary and does not scale well when converting other protocols. Don't store the slash as part of the path. The resulting change from absolute to relative path within the gluster driver should be okay, as the root directory is the default when accessing gluster.

Extract the part formatting the basic URI part so that it can be reused to format JSON backing definitions. Parts specific to the command line format will remain in qemuBuildNetworkDriveURI. The new function is called qemuBlockStorageSourceGetURI.

Original implementation used 'SocketAddress' equivalent from qemu for the disk server field, while qemu documentation specifies 'InetSocketAddress'. The backing store parser uses the correct parsing function but the formatter used the incorrect one (and also with the legacy mode enabled which was wrong).

The file object is needed when formatting the command line, but it makes nesting of the objects less easy for use with blockdev. Separate the wrapping into the 'file' object into a helper used specifically for disk sources in the old code path.

Add helpers that will simplify checking if a backing file is valid or whether it has backing store. The helper virStorageSourceIsBacking returns true if the given virStorageSource is a valid backing store member. virStorageSourceHasBacking returns true if the virStorageSource has a backing store child. Adding these functions creates a central points for further refactors.

Alter qemu command line generation in order to possibly add TLS for a suitably configured domain. Sample TLS args generated by libvirt - -object tls-creds-x509,id=objvirtio-disk0_tls0,dir=/etc/pki/qemu,\ endpoint=client,verify-peer=yes \ -drive file.driver=vxhs,file.tls-creds=objvirtio-disk0_tls0,\ file.vdisk-id=eb90327c-8302-4725-9e1b-4e85ed4dc251,\ file.server.type=tcp,file.server.host=192.168.0.1,\ file.server.port=9999,format=raw,if=none,\ id=drive-virtio-disk0,cache=none \ -device virtio-blk-pci,bus=pci.0,addr=0x4,drive=drive-virtio-disk0,\ id=virtio-disk0 Update the qemuxml2argvtest with a couple of examples. One for a simple case and the other a bit more complex where multiple VxHS disks are added where at least one uses a VxHS that doesn't require TLS credentials and thus sets the domain disk source attribute "tls = 'no'". Update the hotplug to be able to handle processing the tlsAlias whether it's to add the TLS object when hotplugging a disk or to remove the TLS object when hot unplugging a disk. The hot plug/unplug code is largely generic, but the addition code does make the VXHS specific checks only because it needs to grab the correct config directory and generate the object as the command line would do.

The alias recorded in disk->info.alias is the alias for the frontend device but we are interested in the backend drive. This messed up the disk node name extraction code as qemu reports the drive alias in the block query commands. This was broken in the node name detector refactoring done in commit 0175dc6e Resolves: https://bugzilla.redhat.com/show_bug.cgi?id=1494327

The VxHS block device will only use the newer formatting options and avoid the legacy URI syntax. An excerpt for a sample QEMU command line is: -drive file.driver=vxhs,file.vdisk-id=eb90327c-8302-4725-9e1b-4e85ed4dc251,\ file.server.type=tcp,file.server.host=192.168.0.1,\ file.server.port=9999,format=raw,if=none,id=drive-virtio-disk0,cache=none \ -device virtio-blk-pci,bus=pci.0,addr=0x4,drive=drive-virtio-disk0,\ id=virtio-disk0 Update qemuxml2argvtest with a simple test.

Remove the complex and unreliable code which inferred the node name hierarchy only from data returned by 'query-named-block-nodes'. It turns out that query-blockstats contain the full hierarchy of nodes as perceived by qemu so the inference code is not necessary. In query blockstats, the 'parent' object corresponds to the storage behind a storage volume and 'backing' corresponds to the lower level of backing chain. Since all have node names this data can be really easily used to detect node names. In addition to the code refactoring the one remaining test case needed to be fixed along.

New name is qemuBlockStorageSourceBuildHostsJSONSocketAddress since it formats the JSON object in accordance with qemu's SocketAddress type. Since the new naming in qemu uses 'inet' instead of 'tcp' add a compatibility layer for gluster which uses the old name.

由 Peter Krempa 提交于
qemu for some time already sets node names automatically for the block nodes. This patch adds code that attempts a best-effort detection of the node names for the backing chain from the output of 'query-named-block-nodes'. The only drawback is that the data provided by qemu needs to be matched by the filename as seen by qemu and thus if two disks share a single backing store file the detection won't work. This will allow us to use qemu commands such as 'block-set-write-threshold' which only accepts node names. In this patch only the detection code is added, it will be used later.
