"error: operation failed: migration of disk sda failed: No space left on device"
Nikolay Shirokovskiy (3):
qemu: simplify switch case for blockjob events

[libvirt] [libvirt-glib 00/20] gconfig: <graphics> configuration work
by Christophe Fergeau
Hey,
This series groups 2 series which were sent previously for review,
one from Visarion https://www.redhat.com/archives/libvir-list/2016-August/msg00868.html
and one from Fidencio https://www.redhat.com/archives/libvir-list/2016-March/msg00993.html
I'm putting them together as they touch the same piece of code and thus
conflict with each other. The separation would happen at 11/20 "gconfig:
Implement gvir_config_domain_graphics_spice_get_tls_port()" if I were to send
these separately.
Visarion's changes add support for configuring the <listen> node for the
graphics node, and Fidencio's changes add some base classes to make generic
configuration of local/remote graphics nodes easier, regardless of their
type (VNC/SPICE for example).
This incorporate the various changes I suggested during review, in particular
it renames _set_listen_nodes() in the original series to just _set_listen(),
better naming suggestions welcome.
I've also added a few patches of my own which made sense to have for
completeness.

[libvirt] [[PATCH v2] 0/4] try harder to get dest qemu errors on migation
by Nikolay Shirokovskiy
Hi, all.
In case migration fails due to destination qemu exits unexpectedly user
recevies the qemu log in the error message. Unfortunately log is truncated and
the most interesting part is missed (below is the example of such a log [1]).
Actually for the most cases the first patch will be enough to fix the issue.
Originally I thought the problem is qemu logging and reading the log are not in
sync (which is true) so I tried to fix it as well in the next patches.
* diff from v1:
1. split changes to libvirtd and virtlogd to different patches
2. split virtlogd patch further
3. simplify handling eofs and hangups in draining function

[libvirt] [PATCH V2 0/4]] qemu: report actual vcpu state in virVcpuInfo
by Viktor Mihajlovski
Currently, the virVcpuInfo returned by virDomainGetVcpus() will always
report a state of VIR_VCPU_RUNNING for each defined domain vcpu even if
the vcpu is currently in the halted state.
As the monitor interface is in fact reporting the accurate state, it is
rather easy to transport this information with the existing API.
This is done by
- adding a new state of VIR_VCPU_HALTED
- extending the monitor to pass back the halted state for the vcpus
- adding a new field to the private domain vcpu object reflecting the
halted state for the vcpu
- modifying the driver code to report the vcpu state based on the halted
indicator
- extending virsh vcpuinfo to also display the halted state
The vcpu state is however not recorded in the internal XML format, since
the state can change asynchronously (without notification).
V2 is a rebase on top of Peter Krempa's CPU hotplug modernization.
Viktor Mihajlovski (4):
domain: Add new VCPU state "halted"
qemu: Add monitor support for CPU halted state
qemu: Add domain support for VCPU halted state
qemu: Ensure reported VCPU state is current in driver API

[libvirt] [PATCH] qemu: allow 32 slots on pcie-expander-bus, not just 1
by Laine Stump
When I added support for the pcie-expander-bus controller in commit
bc07251f, I incorrectly thought that it only had a single slot
available. Actually it has 32 slots, just like the root complex aka
pcie-root (the part that I *did* get correct is that unlike pcie-root
a pcie-expander-bus doesn't allow any integrated endpoint devices -
only pcie-root-ports and dmi-to-pci-controllers are allowed).

[libvirt] libvirt zsh completions
by Marko Myllynen
Hi,
FWIW, FYI, I've contributed completions for the commands part of libvirt
to zsh upstream, here's a quick screenshot:
$ virsh <TAB>
zsh: do you wish to see all 222 possibilities (111 lines)? n
$ virsh allocpages <TAB>
--add --all --cellno --pagecount --pagesize
$ virsh start <TAB>
f23-test fedora-24-beta rhel-7-server
$ virsh stop <TAB>
f24-test rhel-6-server ubuntu-16.04
$
There's also support for the -c/--connect flag and selective completion
support for the following (domains seen as an example above):
+ domains
+ interfaces
+ networks
+ devices
+ nwfilters
+ pools
+ secrets
+ snapshots
+ volumes
Supported commands are:
virsh virt-admin virt-host-validate virt-pki-validate virt-xml-validate
Since virt-admin requires root/sudo, there are some additional security
checks in zsh upstream to enable sudo for completions only by request.
This will require the next zsh release. I've uploaded a version of these
completions which uses sudo unconditionally to my fedorapeople.org page
and it can be used by the adventurous already today (by placing it under
/usr/share/zsh/*/functions/):

[libvirt] [PATCH RESEND v2 0/5] Implementation of QEMU vhost-scsi
by Eric Farman
[Resending after the release of 2.2.0; no changes other than a rebase
to current master and the associated tweaking to the capabilities patch]
This patch series provides a libvirt implementation of the vhost-scsi
interface in QEMU. As near as I can see, this was discussed upstream in
July 2014[1], and ended in a desire to replace a vhost-scsi controller
in favor of a hostdev element instead[2].
There is no capability check in this series for vhost-scsi in the underlying
QEMU. Using a recent QEMU built with --disable-vhost-scsi fails with "not a
valid device model name."
Host Filesystem Example:
# ls /sys/kernel/config/target/vhost/
discovery_auth naa.5001405df3e54061 version
# ls /sys/kernel/config/target/vhost/naa.5001405df3e54061/tpgt_1/lun/
lun_0
QEMU Example (snippet):
-device vhost-scsi-ccw,wwpn=naa.5001405df3e54061,devno=fe.0.1000
Libvirt Example (snippet):
<hostdev mode='subsystem' type='scsi_host'>
<source protocol='vhost' wwpn='naa.5001405df3e54061'/>
<address type='ccw' cssid='0xfe' ssid='0x0' devno='0x1000'/>
</hostdev>

Changelog:
v2->v2.1:
- Rebased to current master (6 September)
v1->v2: https://www.redhat.com/archives/libvir-list/2016-August/msg01028.html
- Rebase
- Applies to current master (20 August)
- Added a capability check for QEMU 2.7
- Fixed the qemuxml2argv tests as the -smp options had changed
- Reworked ccwaddrs parameter in virDomainCCWAddressAssign call
- Comments
- Squashed documentation, XML schema, XML parsing, and infrastructure
patches into a single patch
- Switched from "hostdev type='scsi'" to "hostdev type='scsi_host'";
this removes the refactoring patches since we're not shoe-horning
a new SCSI protocol into the existing code
- Reworked the handling of the fd's such that we send them to qemu
after any possible errors could occur and cause us to back out
- s/qemuBuildSCSIVhostHostdevDevStr/qemuBuildHostHostdevDevStr/
- Added virBufferCheckError, and an error message for vhostfdSize > 1,
in qemuBuildHostHostdevDevStr
- Added qemuBuildDeviceAddressStr in qemuBuildHostHostdevDevStr, thus
superceding the last patch in the v1 series
- Other
- Simplified the vhostfd logic to just be a single int, rather than
an alloc'd array (left the vhostfdSize described above as an
identifier for if QEMU ever supports multiple vhostfds)
- Replaced "qemuMonitorAddDevice" with "qemuMonitorAddDeviceWithFd"
in hotplug routine
