[libvirt] [PATCH 0/3] more virCommand cleanups
by Eric Blake
When I first reviewed Cole's virCommand cleanups, I pointed out some
possible later cleanups. Here they are.
Eric Blake (3):
command: reduce duplicated debug messages
command: avoid double close
storage: avoid an intermediate malloc

[libvirt] [PATCH] Fix errno return in safezero()
by Daniel P. Berrange
Most of the safezero() implementations return -1 on error,
setting errno. The safezero() impl using posix_fallocate()
though returned a positive errno value on error (due to
the unusual API contract of posix_fallocate() compared to
most syscall APIs).
* src/util/util.c: Ensure safezero() returns -1 and sets
errno on error.
* src/storage/storage_backend.c: Change safezero != 0 to
< 0 for detecting errors

[libvirt] Virt Tools Blog Planet (RSS feed aggregator)
by Daniel P. Berrange
The virt-tools.org website, launched last year, provides tutorials,
videos, documentation, online help and roadmaps relevant to libvirt,
libguestfs, gtk-vnc, spice, other related libraries, and tools or
applications like virt-manager & virt-install. The site goal is to
inform & assist end users, system administrators & application
developers who wish to learn about the capabilities of the virt tools
stack. The focus of most content is the, state of the art, Linux native
KVM hypervisor, but writing about using other hypervisors using virt
tools is also welcome.
Today we are launching a new part of the site, the Blog Planet, to
aggregate feeds from people working on virt tools related projects:
http://planet.virt-tools.org/index.html
The site is seeded with a mere 2 blogs thus far, and so we are looking
for content from other people working on libvirt, libguestfs, gtk-vnc,
spice, and any other infrastructure/tools which integrate with them.
The aim is for the Blog Planet to contain content directly useful to
end users, system administrators and application developers. To that
end, it is desirable if your blog feed can be filtered to just include
content directly related to virt tools.
Any wordpress users can trivially do this by assigning either categories
or tags to their posts, which the provide dedicated RSS feeds; other blog
software hopefully has similar capabilities.
To be included on the planet, send (off-list) your RSS feed URL and a
Hackergotchi face icon (upto an absolute max of 96x96 pixels in size).
Regards,
Daniel

[libvirt] [PATCH v4 0/5] Add TXT record and hosts support for DNS service and dnsmasq command-line regression testing
by Michal Novotny
Hi,
this is the patch to introduce the TXT record and DNS hosts support
for the DNS service on the virtual network. This can be defined using
the txt-record subelement in the dns element of the network XML
description. The definition of TXT record names containing spaces
is rejected with the error message that TXT record names in DNS
doesn't support spaces.
Also, regression testing for the dnsmasq command line has been
added to test whether the dnsmasq command-line is correct or not.
The new XML definition syntax is:
<dns>
<txt name="example" value="example value" />
<host ip='192.168.122.1'>
<hostname>gateway</hostname>
<hostname>host</hostname>
</host>
</dns>
Where multiple host elements can be defined to put the aliases.
The <dns> element have to be present on the <ip> level, i.e.
one level upper than it was in version 2 of the patch since
the definition affects all the IP addresses on the network.
The patch series has been tested for the configuration and it
was working fine and also RelaxNG schema with the tests have
been both altered to add test cases to test those patches.
This is the new version for latest libvirt codebase so please
review the patchset.
Thanks,
Michal
