[PATCH] network: inhibit idle timeout of daemon if there are any active networks
by Laine Stump
When the daemons were split out from the monolithic libvirtd, the
network driver didn't implement "inhibit idle timeout if there are any
active objects" as was done for other drivers, so virtnetworkd would
always exit after 120 seconds of no incoming connections. This didn't
every cause any visible problem, although it did mean that anytime a
network API was called after an idle time > 120 seconds, that the
restarting virtnetworkd would flush and reload all the
iptables/nftables rules for any active networks.
This patch replicates what is done in the QEMU driver - an nactive is
added to the network driver object, along with an inhibitCallback; the
latter is passed into networkStateInitialize when the driver is
loaded, and the former is incremented for each already-active network,
then incremented/decremented each time a network is started or
stopped. If nactive transitions from 0 to 1 or 1 to 0, inhibitCallback
is called, and it "does the right stuff" to prevent/enable the idle
timeout.

I had made this patch as a part of a larger series that will require
it, but haven't sent that yet and keep being annoyed when virtnetworkd
exits out from under a gdb session, so I decided it has enough general
usefulness to send by itself.

[PATCH v2] chardev: introduce 'reconnect-ms' and deprecate 'reconnect'
by Daniil Tatianin
The 'reconnect' option only allows to specify the time in seconds,
which is way too long for certain workflows.
We have a lightweight disk backend server, which takes about 20ms to
live update, but due to this limitation in QEMU, previously the guest
disk controller would hang for one second because it would take this
long for QEMU to reinitialize the socket connection.
Introduce a new option called 'reconnect-ms', which is the same as
'reconnect', except the value is treated as milliseconds. These are
mutually exclusive and specifying both results in an error.
'reconnect' is also deprecated by this commit to make it possible to
remove it in the future as to not keep two options that control the
same thing.

Changes since v0:
- Mention the deprecation in docs (Paolo)
Changes since v1:
- Move option validation to qmp_chardev_validate_socket as qemu_chr_parse_socket
is only called for the command line and not QMP. (thanks to Markus Armbruster for spotting)

[PATCH V3] libxl: Reject VM config referencing nwfilters
by Jim Fehlig
The Xen libxl driver does not support nwfilter. Introduce a
deviceValidateCallback function with a check for nwfilters, returning
VIR_ERR_CONFIG_UNSUPPORTED if any are found. Also fail to start any
existing VMs referencing nwfilters.
Drivers generally ignore unrecognized XML configuration, but ignoring
a user's request to filter VM network traffic can be viewed as a
security issue.

V2:
https://lists.libvirt.org/archives/list/devel@lists.libvirt.org/message/U...
Changes in V3:
When starting a VM, use virDomainDefValidate to validate the def instead
of duplicating the checks.
Note: With the change in V3, the validation is only done when starting
a new VM. Validation is skipped if restoring a managed saved VM.

[PATCH V2 0/2] qemu: Clarify purpose of image format settings
by Jim Fehlig
The current documentation of the various foo_image_format settings in
qemu.conf subtly implies they are only used for specifying compression.
Patch1 of this small series attempts to clarify and improve the description
of the settings. It defines image format as a way to specify the desired
layout of guest memory blocks on disk.
Patch2 changes the use of 'compressed' with 'format' throughout the
code, removing implication that format == compressed.
V2:
Replace more uses of 'compressed' with 'format' in patch2

[PATCH 0/7] qemu: Fix some more migration issues related to vmx-* features
by Jiri Denemark
Sigh.
Jiri Denemark (7):
qemu: Drop vmx-* from migratable CPU model only when origCPU is set
qemu: Do not drop unknown CPU features from domain XML
cpu-data.py: Properly handle aliases
qemu: Translate vmx-invvpid-single-context-noglobals CPU feature
qemu: Replace big condition in virQEMUCapsCPUFilterFeatures with array
cpu_map: Drop vmx-ept-{uc,wb} features from CPU models
cpu_map: Drop vmx-invvpid-single-context from CPU models
