From 895231d5605e63882de015d7b99cea36e9174d66 Mon Sep 17 00:00:00 2001 From: Cedric Bosdonnat <cbosdonnat@suse.com> Date: Tue, 1 Sep 2020 10:38:39 +0200 Subject: [PATCH] Opensuse 3000.2 virt backports (#236) (#257) * Revert "virt._get_domain: don't raise an exception if there is no VM" This reverts commit 9d433776fc252ab872b331cfa7fc940c42452f83. * Revert "openSUSE-3000 virt-defined-states (#222)" This reverts commit 900fdc4d5bcfdac933f9a411d38b92ef47dd1ef5. * Revert "Add virt.all_capabilities" This reverts commit 96e8307b531f7e51f5587f66a51dc52ad246c8c1. * Blacken salt -- virt only * virt._get_domain: don't raise an exception if there is no VM Raising an exception if there is no VM in _get_domain makes sense if looking for some VMs, but not when listing all VMs. * fixed bug on update existing boot parameters * add support to boot vm with UEFI * virt: don't depend on ElementTree.tostring to compare XML fragments ElementTree.tostring() implementation starts to keep the attribute order defined by the user in python 3.8. This can lead to equal elements to be considered different. Use xmlutil.to_dict(element, True) to compare the elements. This also uncovered a wrong behavior of pool_update when only changing the password. * openSUSE-3000 virt-defined-states (#222) * Create virt.pool_defined state out of virt.pool_running Users may want to use states to ensure a virtual storage pool is defined and not enforce it to be running. Extract the code that performs the pool definition / update from virt.pool_running state into a virt.pool_defined. Obviously the virt.pool_running state calls the virt.pool_defined one. In such a case no additionnal test is needed for virt.pool_defined since this is already tested with virt.pool_running. * Add virt.update test parameter In order to allow running dry-runs of virt.update module add a test parameter. This will later be used by the virt states. * Extract virt.defined state from virt.running In order to ensure a virtual guest is defined independently of its status, extract the corresponding code from the virt.running state. This commit also handles the __opts__['test'] for the running state. Since the update call only performs changes if needed, deprecate the update parameter. * Extract virt.network_defined from virt.network_running Just like domains and storage pools, users may want to ensure a network is defined without influencing it's status. Extract the code from network_running state defining the network into a network_defined state. While at it, support __opt__['test'] == True in these states. Updating the network definition in the pool_defined state will come in a future PR. * Fix virt.update to handle None mem and cpu virt.running state now may call virt.update with None mem and cpu parameters. This was not handled in _gen_xml(). Also add some more tests cases matching this for virt.update. * Add support to virt for libvirt loader * Add bhyve compatibility to virt * Fix test_get_hypervisor: mock bhyve * Add virt.all_capabilities In order to get all possible capabilities from a host, the user has to call virt.capabilities, and then loop over the guests and domains before calling virt.domain_capabilities for each of them. This commit embeds all this logic to get them all in a single virt.all_capabilities call. * Virt init disks support (PR#56666) * Fix pylint warning in test_virt.py after blackening * Add pool parameter to virt.define_vol_xml_str * Remove useless default values for disks and vm_name in _disk_profile * virt._gen_vol_xml: move all esx-specifics outside In the near future gen_vol_xml will be able to handle many volume types, not only for ESX volumes. For this, clean up the function from all the ESX-specifics code and move them to the caller code. The volume key and target path values have also been removed since those are read-only elements that should not be provided for volume creation as per https://libvirt.org/formatstorage.html#StorageVol * virt: add more properties to generate volume XML In order to generate almost all the volumes that libvirt can handle, add the type, backingStore, permissions and allocation parameters to the virt._gen_vol_xml() function. Also make the format parameter optional since libvirt has default values depending on the storage backend. * virt.define_vol_xml_str variant using an existing libvirt connection In order to avoid connection multiple times when reusing this function in the virt module, create _define_vol_xml_str not caring about the connection opening and closing. * Add virt.volume_define function In the same vein than pool_define and network_define, expose a volume_define function to let users create a volume without needing to know all of libvirt's XML details. * Add virt.volume_upload function When using volumes the user can just copy the template disk image into the target path. In such a case, the image needs to be uploaded into the volume. * virt.capabilities refactoring Extract the libvirt-handling code from virt.capabilities into a virt._capabilities function accepting an opened libvirt connection. This allows reusing the code in other functions with easy connection handling. * Extract virt.pool_capabilities logic for use with a libvirt connection Te virt.pool_capabilities function computes a lot of interesting values on the virtual storage pool types. Extract the logic of it into virt._pool_capabilities for reuse. * Share libvirt connection in virt.init Since the next commits will introduce more uses of the libvirt connection in virt.init(), start sharing it now. * Add disk volumes support in virt.init In order to support creating VMs with disk on more storage pools like iSCSI, disks, LVM, RBD, etc, virt.init needs to handle disks not only as files, but also as libvirt volumes. * fix libvirtError use libvirtError is not defined, libvirt.libvirtError should be used instead. * virt: let libvirt generate MAC addresses There is no need to generate MAC addresses in the virt module if the user hasn't provided any. This only makes it harder to make the difference between a real mac address change from the user and a new generated one. Now the mac address is not written in the domain XML definition if not provided by the user. This avoids unnecessary changes when applying virt.running. * virt.update handle disk volumes * virt.volume_infos: output backing store as well Since it could be useful to know whether a volume has a backing store, output the path and format of the backing store if any is defined. * virt.volume_infos: output disk format Since the format of a volume may be of interest and could help to tell if two volumes are similar, output this information in the virt.volume_infos function. * Add virt.volume_defined state In order to help creating storage volumes in virtual storage pools from states, add a virt.volume_defined state. * Add volume support to virt._get_disks If a virtual machine has disks of volume types, they will now be reported by the virt._get_disk() function and all the user-exposed functions using it like virt.get_disks(), virt.vm_info() and virt.full_info(). * Add volume disks support to virt.purge() virt.purge will now remove not only the file disks, but also the disk volumes. * Handle RBD volumes as network disks in VM definition libvirt doesn't support attaching RBD storage pool volumes to a VM. For instance, a disk with such a source is invalid: <source pool='rbd-pool' volume='rbd-volume'/> And needs to be replaced with: <source protocol="rbd" name="rbd-pool-name/rbd-volume"> <host name="hostname" port="7000"/> <auth username='myuser'> <secret type='ceph' usage='mypassid'/> </auth> </source> This means that we need to fetch the connection data from the pool definition and convert the volume disk definition into a network one when creating the VM. This also means that when purging the VM we need to search for the pool by looking in every pool's XML to delete the volume. * virt: fix VM creating with disk volume Since volumes in a virtual storage pool of type 'disk' are partitions, then need to be named after the disk name with sequential numbers rather than using the VM and disk names. Also, the format passed by the user is the one used when creating the volume. However in the VM definition for logical and disk volumes, the format should be set to raw. * virt: handle cdrom remote images Libvirt allows to use network images for cdroms. Use them if the image is a remote URL for a cdrom device. * virt.update properly handle removable devices Live attaching / detaching removable devices results in failures. To change the source of those, we need to call updateDeviceFlags instead. * improve boot parameter documentation (PR#57086) * Remove buggy start parameter from virt.pool_running docstring As mentioned by issue #57275, the start parameter in virt.pool_running documentation is not implemented at all. Remove it from the doc. * virt: fix removable_changes definition place * virt: show the proper pool name in get_disks From the user point of view the internal RBD pool name doesn't make sense when listing the disks of a VM. We need then to resolve it to the libvirt pool name if possible. Move the corresponding code from purge to get_disks. * virt: fix updating VM with backing store disks libvirt adds the index attribute in the XML definition when there is a backing store file for a disk. We need to elude it before comparing the sources to avoid trying to recreate disks in such cases. * virt: default cdrom model to ide cdrom devices can't use virtio. Set the default bus to ide for cdroms. * virt.get_disk: output the full URL for cdroms with remote image virt._gen_xml converts the cdroms with remote URL into a network device, but to be coherent with the user input the virt.get_disk() function needs to reassemble the URL in thoses cases. * virt.pool_delete: remove also secret Some pool type require a secret for the authentication on the remote source. Remove the secrets that were added by pool_defined but leave the others in place. * virt.init: cdrom format default to raw cdrom sources can't be of format qcow2. Force raw as the default if needed when creating VM with source_file set for the cdrom. * virt.init: fix disk target names Fixes issue #57477. * virt.update: handle changing cdrom images for devices with remote source When a DVD device on a VM has a remote source, virt.update needs to be able to handle detaching it and attaching a file image live. * virt.init: fix the name of volumes reused in disk-types pools Only compute the partition name if no source_file was provided by the user for a pool of disk type.
