Daniel P. Berrange c7d0fbe62b libvirtd: add config option for TLS priority
Add a "tls_priority" config option to /etc/libvirt/libvirtd.conf
to allow the administrator to override the built-in default
setting. This only affects the server side configuration.

Daniel P. Berrange 214489f550 rpc: allow priority string to be passed to TLS context
Extend the virNetTLSContextNew* constructors to allow
the TLS priority string to be passed in, overriding the
compile time default.

Daniel P. Berrange cbb2e91ecc configure: allow setting default TLS priority string
Currently libvirt calls gnutls_set_default_priority()
which on old systems resolves to "NORMAL" while new
systems it resolves to "@SYSTEM". Either way, this
is a global default that is identical across all apps.

We want to allow distros to flexibility to define a
custom default string for libvirt priority, so add
a --tls-priority=STRING  flag to configure to enable
this to be set.

It is expected that distros would use this when creating
RPM/Deb/etc packages, according to their preferred crypto
handling policies.

Daniel P. Berrange 20c5ded9d0 rpc: set gnutls log function at global init time
Currently we set the gnutls log function when creating a
TLS context, however, the setting is in fact global, not
per context. So we should be setting it when we first call
gnutls_global_init() instead.

Daniel P. Berrange d8a8af3492 tls: remove support for gnutls 1.x.x, require 2.2.0
We need to use the gnutls_priority_set_direct method which
was not introduced until 2.1.7, so bump version to 2.2.0
which is the first stable release with it included. This
release dates from Dec 2007 so it is reasonable to ditch
support for the 1.x.x series for gnutls releases entirely.

Pavel Hrdina 4ddde38e2d virsh: domdisplay: if listen is 0.0.0.0 or [::] print address from URI
Currently if a guest has listen address 0.0.0.0 or [::] and you run
"virsh domdisplay $domain" you always get "spice://localhost:$port".

We want to print better address if someone is connected from a different
computer using "virsh -c qemu+ssh://some.host/system".  This patch fixes the
behavior of virsh to print in this case "spice://some.host:$port".

Michal Privoznik 6895068d6d virschematest: Access the right directory containing XMLs
So the story goes like this. The testSchemaDirs() function is
called with: a) the schema file, b) list of the directories that
contains XMLs documents that should be checked against the schema
file from a). However, the directories in the list are really
just their names and it's up to testSchemaDirs to construct the
absolute path and call testSchemaDir() which then does the actual
validation. The absolute path is constructed, but never actually
used (maybe due to a typo). Thus a VPATH build is broken.

Peter Krempa 9cda91d6f6 qemu: process: Call disk startup policy check after cloning domain def
In commit 1e38ef72 the disk startup policy check was moved prior to the
call to virDomainObjSetDefTransient which dropped the disk from the
config rather than the def to be started which is a bug.

Additionally we'd not report the disk change event for this since the
disk aliases were not set at that point.

Finally 'volume' based disks would not work with startup policy too.

Fix it by moving it back after the definition is copied, aliases are
assigned and disk sources are translated.

needed.

Peter Krempa 5e6143fbcc log: handler: Add new API to append to logging files
For logging one-shot entries to the VM log file it's quite a waste to
hold open the file descriptor for logging that is provided by the
current API.

This new API will be ideal for logging one-shot entries to the file
e.g. at the point when we shut the VM down rather than having to add the
whole file-descriptor infrastructure.

Additionally this will allow to add the messages even after restart of
libvirtd since virtlogd doesn't allow to obtain a regular context with
filedescriptors while the VM is still active.
