[libvirt] [PATCH RFC V2] guests: Add support for openSUSE
by Jim Fehlig
This change adds support for the latest openSUSE Leap and
openSUSE Tumbleweed guests.
Signed-off-by: Jim Fehlig <jfehlig(a)suse.com>
---
This version of the patch overcomes the 'lci build' issues noted in V1
and works well for openSUSE Leap 15.1 and Tumbleweed. I'm still of the
opinion of only supporting the latest Leap since there is only a six
month support overlap between versions. Version x-1 is only supported
six months after x is released.
'lci update ... libvirt' fails in task "Configure hostname":
fatal: [libvirt-opensuse-tumbleweed]: FAILED! => {"changed": false, "msg": "hostname module cannot be used on platform Linux (Opensuse-tumbleweed)"}
Not sure why that is the case. But more importantly, even though it
doesn't fail, the "Update installed packages" task doesn't install any
of the packages required to build libvirt. I suppose that agrees with
guests/REAMDME, but how then are the packages required to build $project
installed? How/when is the list of packages required to build $project
conveyed to $package_manager?
'lcitool build libvirt-opensuse-tumbleweed libvirt' fails in the
"Gathering Facts" task:
fatal: [libvirt-opensuse-tumbleweed]: UNREACHABLE! => {"changed": false, "msg": "Invalid/incorrect password: ", "unreachable": true}
Passing --debug to the command didn't help with determining what needed
the password. ssh? I can't find where the "Gathering Facts" task is
defined. The $root_password_file passed to /usr/bin/ansible-playbook
contains the correct password for the root user. /me needs to figure
out how to better debug this stuff :-).

[libvirt] [PATCH v3 0/4] qemu: block: implement optional removal of committed snapshot images
by Pavel Mores
v3 aims to incorporate Peter's feedback to v2, mainly:
- patch 1 was split into two - the delete flag propagation stays in patch 1,
the actual enabling the feature was moved to what's now patch 4
- patch 2 was modified to handle NFS and to use g_strerror() instead of
strerror_r()
- the former patch 4 was squashed into patch 3.
Pavel Mores (4):
qemu: block: propagate the delete flag to where it can actually be
used
qemu: block: use the delete flag to delete snapshot images if
requested
qemu: block: store the delete flag in libvirtd's status XML
qemu: block: enable the snapshot image deletion feature

[libvirt] [PATCH 00/21] Incremental backup support for qemu
by Peter Krempa
This is a finished version of my RFC posted here:
https://www.redhat.com/archives/libvir-list/2019-October/msg01193.html
All cleanups of that series are now merged and this series has new
cleanups and depending patches that I posted earlier this week. For
convenience everything can be fetched at:
git fetch https://gitlab.com/pipo.sk/libvirt.git blockdev-backup
This series requires qemu 4.2 to work properly. Please make sure to
fetch the current head.
Compared to previous versions:
- The API is similar to what was posted last time or in Eric's version
- the backup job ID was removed, this can't be integrated with qemu
async jobs as there is only one async jobs.
- the virDomainBackupEnd API was removed as virDomainAbortJob can be
used instead
- the usage of domain job APIs is fully implemented as it was documented
in previous eric's postings
- the domain job completion event and completed job statistics are used
to notify about the state and successful finishing of the job
(see virDomainGetJobStats/virsh domjobinfo)
- unfortunately block jobs and snapshots are still not supported, thus
this feature will stay disabled for now:
If you want to give the feature a spin you must use the following XML
override:
<domain type='kvm' xmlns:qemu='http://libvirt.org/schemas/domain/qemu/1.0'>
...
<qemu:capabilities>
<qemu:add capability='incremental-backup'/>
</qemu:capabilities>
</domain>
Eric Blake (5):
backup: Document new XML for backups
backup: Introduce virDomainBackup APIs
backup: Implement backup APIs for remote driver
backup: Parse and output backup XML
backup: Implement virsh support for backup
Peter Krempa (16):
API: Introduce field for reporting temporary disk space usage of a
domain job
virsh: Implement VIR_DOMAIN_JOB_DISK_TEMP_(USED|TOTAL) in
cmdDomjobinfo
API: Add domain job operation for backups
qemu: Add infrastructure for statistics of a backup job
qemu: domain: Introduce QEMU_ASYNC_JOB_BACKUP async job type
Add 'backup' block job type
qemu: monitor: Add support for blockdev-backup via 'transaction'
qemu: domain: Track backup job data in the status XML
qemu: blockjob: Track internal data for 'backup' blockjob
tests: qemustatusxml2xml: Add test for 'pull' type backup job
conf: backup: Add fields for tracking stats of completed sub-jobs
doc: Document quirk of getting block job info for a 'backup' blockjob
qemu: Implement backup job APIs and qemu handling
qemu: backup: Implement stats gathering while the job is running
qemu: driver: Allow cancellation of the backup job
qemu: blockjob: Implement concluded blockjob handler for backup

[libvirt] CLZERO support for AMD
by Ani Sinha
Hi :
I see a commit in qemu that adds support for CLZERO but in CPUIDs. :
commit e900135dcfb676a4019dc206395e02db5d1de0d6
Author: Sebastian Andrzej Siewior <bigeasy(a)linutronix.de>
Date: Wed Sep 25 23:49:48 2019 +0200
i386: Add CPUID bit for CLZERO and XSAVEERPTR
The CPUID bits CLZERO and XSAVEERPTR are availble on AMD's ZEN platform
and could be passed to the guest.

Is there a corresponding change in libvirt adding this capability? Libvirt complains when I add it manually in the vm xml:
# virsh create newvm.xml
error: Failed to create domain from newvm.xml
error: unsupported configuration: unknown CPU feature: clzero
# grep clzero newvm.xml
<feature policy='require' name='clzero'/>
Should we add it?
thanks

[libvirt] [PATCH 0/9] qemu: clean up capability handling during startup (incremental backup prequels)
by Peter Krempa
For libvirt to use incremental backup we will require that blockdev is
enabled. Clean up how we handle caps during startup since blockdev may
be masked out there and add infrastructure to interlock flags.
Peter Krempa (9):
qemu: process: Make it obvious that virDomainDefPostParse is called
with NULL opaque
qemu: process: Don't try to redetect missing qemuCaps on reconnect
qemu: Move and rename qemuDomainUpdateQEMUCaps
qemu: process: Move clearing of the BLOCKDEV capability to
qemuProcessPrepareQEMUCaps
qemu: process: Move clearing of QEMU_CAPS_CHARDEV_FD_PASS to
qemuProcessPrepareQEMUCaps
qemu: process: Move handling of qemu capability overrides
qemu: caps: Don't check capability before clearing it
qemu: capabilities: Lock out incremental backup capability without
blockdev
qemu: process: Re-process qemu capability lockout in
qemuProcessPrepareQEMUCaps

[libvirt] [PATCH] spec: Disable gluster on i686 on RHEL-8
by Jiri Denemark
Gluster 6.0 is not built on i686 for RHEL-8, which prevents libvirt from
building. Let's just disable gluster there as all we need are client
libraries anyway.

[libvirt] [PATCH] remote_daemon_stream: Hold an extra reference to stream in daemonStreamFilter
by Michal Privoznik
In v5.9.0-273-g8ecab214de I've tried to fix a lock ordering
problem, but introduced a crasher. Problem is that because the
client lock is unlocked (in order to honour lock ordering) the
stream we are currently checking in daemonStreamFilter() might be
freed and thus stream->priv might not even exist when the control
get to virMutexLock() call.
To resolve this, grab an extra reference to the stream and handle
its cleanup should the refcounter reach zero after the deref.
If that's the case and we are the only ones holding a reference
to the stream, we MUST return a positive value to make
virNetServerClientDispatchRead() break its loop where it iterates
over filters. The problem is, if we did not do so, then
"filter = filter->next" line will read from a memory that was
just freed (freeing a stream also unregisters its filter).

Reproducing this issue is very easy:
1) put sleep(5) right after virObjectUnlock(client) in the fist hunk,
2) virsh console --force $dom and type something so that the stream
has some data to process
3) while 2) is still running, run the same command from another terminal
4) observe libvirtd crash
