[libvirt] [PATCH RFC 0/2] virsh: Introduce basic autocompletion
by Michal Privoznik 31 Oct '17

31 Oct '17

This is supposed to go on the top of: https://www.redhat.com/archives/libvir-list/2017-October/msg01367.html Before digging any deeper to this hole I want to make sure that this approach is acceptable. So how does this work. The idea is to have handful of generic functions that fetch names (so called completers). Basically, one completer per each libvirt object. The returned names are then matched against (partial) user input and only matching strings are then offered to the user. Moreover, among having .completer each option has .completer_flags which can refine the completer's behaviour. For instance, in 2/2 I'm introducing virshDomainNameCompleter() which does nothing more than virConnectListAllDomains(). However, since it doesn't make much sense to start already running domain, for the 'start' command .completer_flags is set to VIR_CONNECT_LIST_DOMAINS_INACTIVE so that only inactive domains are returned in the list. What is missing? What is implemented here are vshCmdOptDef completers. The general vshCmdDef completers are still missing. Therefore: virsh # start --domain<TAB><TAB> works and lists inactive domains, but: virsh # start<TAB><TAB> doesn't (well, apart from offering options for the 'start' command). While that would be certainly nice feature to have, it'd require more work, because some arguments are "implicit" based on position. For instance: virsh # attach-interface fedora network default which is equivalent to: virsh # attach-interface --domain fedora --type network --source default Also, bash autocompletion is missing. The idea there is to have an unlisted virsh command that the bash script can call in order to fetch list of options. But again, no movement in that area yet.

[libvirt] [PATCH RFC] lib: provide error message in new blockjob event
by Nikolay Shirokovskiy 31 Oct '17

31 Oct '17

If block job is completed with error qemu additionally provides error message. This patch introduces new event VIR_DOMAIN_EVENT_ID_BLOCK_JOB_3 to pass error message to client. --- The patch is applied on top of [1] patch series (not yet pushed though). Looks like this patch consists of too much boilerplate code only to pass extra string parameter for blockjob event but looks like there is no other way now. Especially ugly looking is adding event3 in src/qemu/qemu_blockjob.c. Actually there is old RFC for providing error message for blockjob event [2]. Hope this one gain more attention.

[libvirt] [PATCH] virsh: Define multi line macros properly
by Michal Privoznik 31 Oct '17

31 Oct '17

In some cases there's dangling backward slash at the end of multi line macros. While technically the code works, it will stop if some empty lines are removed.

[libvirt] [PATCH 0/2] qemu: Fix QoS for vhostuser
by Michal Privoznik 30 Oct '17

30 Oct '17

Setting QoS on the fly does work for vhostuser. However, it doesn't when starting a domain. So when looking into this, I realized that we should be more explicit about types of interface that do support QoS.

by mkasik＠redhat.com 30 Oct '17

Hi, libvirt-glib has unit tests which can be evaluated as a part of build of RPM. It is generally recommended to run these tests so that some problems can be cought soon enough before the package gets to the users. Please, enable these tests for libvirt-glib. I've done scratch-build of this in koji and the build passes as well as the tests.

[libvirt] [PATCH] qemu: snapshot: Keep non-persistent changes alive in snapshot
by Kothapally Madhu Pavan 30 Oct '17

30 Oct '17

Restoring to a snapshot should not overwrite the persistent configuration xml of a snapshot as a side effect. This patch fixes the same. Currently, virDomainSnapshotDef only saves active domain definition of the guest. And on restore the active domain definition is used as both active and inactive domain definitions. Thiswill make the non-persistent changes persistent in snapshot image. This patch allows to save inactive domain definition as well and on snapshot-revert non-persistent configuration is restored as is. Currently, snapshot-revert is making non-presistent changes as persistent. Here are the steps to reproduce. Step1: virsh define $dom Step2: virsh attach-device $dom $memory-device.xml --live Step3: virsh snapshot-create $dom Step4: virsh destroy $dom Step5: virsh snapshot-revert $dom $snapshot-name Step6: virsh destroy $dom Step7: virsh start $dom Here we still have $memory-device attached in Step2. This patch is attempting to solve this issue.

[libvirt] Using XML returned from domain hook script
by Jim Fehlig 30 Oct '17

30 Oct '17

Hi All, It may be a foolish en devour, but I'm trying to make a qemu hook script that provides the semantics of an old, custom xen block script. The script parses <disk> info, does some setup based on that, and then rewrites part of the config based on results of the setup. As an example, here is an XML snippet of a <disk> device on input to the hook script <disk type='block' device='disk'> <driver name='qemu' type='raw'/> <source dev='some-dev-config'/> <target dev='vdb' bus='virtio'/> </disk> and XML returned by the script <disk type='block' device='disk'> <driver name='qemu' type='raw'/> <source dev='/dev/foo'/> <target dev='vdb' bus='virtio'/> </disk> The hook script performs the setup and substitution in the "prepare" phase, but I noticed the results are never used when subsequently starting the domain. Indeed qemuProcessStartHook passes a NULL buffer to virHookCall, so the output XML of the hook is never collected. Does anyone have objections to using the XML returned from the "prepare" and "release" hook script phases, similar to how it is used in the "restore" and "migrate" phases? WRT the "release" phase, for my hack to work I'd need the original value of the dev attribute ('some-dev-config' in the above example). ISTR some patches on the list to add a metadata element for <devices>. Perhaps those patches would come in handy as a place to store the original dev attribute value. Thanks for your comments! Regards, Jim
