[libvirt] Small postpone of the 0.9.10 freeze
by Daniel Veillard
I'm finally back from vacation, and looking at the list
it seems there is many patches floating that should be pushed
for 0.9.10 . I suggest then to take a few more days to try
to push patches especially about APIs, and enter the freeze
on Monday instead. So we have a couple more working days
to try to push features to git before 0.9.10 freeze,
Daniel

[libvirt] [PATCHv3 0/4] API for modification of domain metadata
by Peter Krempa
This third version incorporates fixes of Eric's review and a rebase on
the top of Jirka's new API.
Differences to v2:
xml: Add element <title> to allow short description of domains
- Move <title> before <description>
- fix tests to accomodate this
- remove forgotten length limits from docs
- fixed XML schema to work around libxml2 newline escape bug
API: Add api to set and get domain metadata
- added new remote procedures to remote_protocol-structs
( and installed tools to detect it in the future :( )
- Fixed function docs to accomodate new code semantics
- Changed error message to sync with other API functions
- Changed debug prints to print strings instead of pointers
- Removed conditions forbidding expansion/work with newer versins
- Changed RPC return type to nonnull_string
virsh: Add support for modifying domain description and titles
qemu: Add support for virDomainGetMetadata and virDomainSetMetadata
- no changes

[libvirt] oVirt Live Snapshots
by Federico Simoncelli
Hi,
oVirt, and more specifically VDSM, is currently implementing the live
snapshot feature using the API/commands provided by libvirt and qemu.
It would be great if you could review the design and the current open
issues at:
http://ovirt.org/wiki/Live_Snapshots
Thank you,

[libvirt] [PATCH] virsh: Plug memory leak on cmdUndefine
by ajia＠redhat.com
From: Alex Jia <ajia(a)redhat.com>
Detected by valgrind. Leak is introduced in commit 3bb6bcf.
Free 'vol' memory before allocating memory, the codes will miss one time
free when 'vol_i = nvolumes' in for loop, so plug memory leak.
* tools/virsh.c: fix memory leak on cmdUndefine.
* How to reproduce?
% dd if=/dev/null of=/var/lib/libvirt/images/foo bs=1 count=1 seek=10M
% virsh define foo.xml (disk source file points to '/var/lib/libvirt/images/foo')
% virsh vol-clone foo foo-clone default (the original guest name is 'foo')
% virsh pool-refresh default
% virsh vol-list default (make sure 'foo-clone' volume exists)
% virsh define foo-clone.xml (disk source file points to '/var/lib/libvirt/images/foo-clone')
% valgrind -v --leak-check=full virsh undefine foo-clone --remove-all-storage
* Actual results:
1. virsh output
Domain foo-clone has been undefined
Volume '/var/lib/libvirt/images/foo-clone' removed.
error: Failed to disconnect from the hypervisor, 1 leaked reference(s)
2. valgrind result

[libvirt] [PATCH] xen_xs: name xendConfigVersion magic numbers
by Philipp Hahn
libvirt supports 4 different versions of the user-land XenD daemon. When
queried the daemon just returns its generation number, which is hard to
match to the version of the Xen tools.
Replace the magic generation numbers by named macro definitions to
improve code readability.

[libvirt] [PATCH v2] tests: dynamically replace dnsmasq path
by Philipp Hahn
The path to the dnsmasq binary can be configured while in the test data
the path is hard-coded to /usr/bin/. This break the test suite if a the
binary is located in a different location, like /usr/local/sbin/.
Replace the hard coded path in the test data by a token, which is
dynamically replaced in networkxml2argvtest with the configured path
after the test data has been loaded.
(Another option would have been to modify configure.ac to generate the
test data during configure, but I do not know of an easy way do trick
configure into mass-generate those test files without listing every
single one, which I consider less flexible.)
v2:
- Use VIR_REALLOC_N() instead of realloc()
- Use memcpy() for replacement
- Skip shrinking buffer
- Add missing update of token_end
- simplify code after the changes above
- unit-test the unit-test:
#include <assert.h>
#define TEST(in,token,rep,out) { char *buf = strdup(in); assert(!replaceTokens(&buf, token, rep) && !strcmp(buf, out)); free(buf); }
TEST("", "AA", "B", "");

[libvirt] [PATCH v2] tests: virnettlscontexttest needs gnutls-2.6.0
by Philipp Hahn
virnettlscontexttest uses gnutls_x509_crt_set_subject_alt_name() and
GNUTLS_FSAN_APPEND, which - according to
<http://www.gnu.org/software/gnutls/manual/gnutls.html> - are only
available since 2.6.0.
Since libvirt still works fine with gnutls-1.0.25 from RHEL5, only
enable the test when the version of GNUTLS is at least 2.6.0.
v2: greater-equal 2.6.0 instead of strictly greater.

[libvirt] [PATCH 0/3] add virDomainBlockRebase
by Eric Blake
As discussed here:
https://www.redhat.com/archives/libvir-list/2012-January/msg01448.html
Qemu patch series here:
https://lists.gnu.org/archive/html/qemu-devel/2012-01/msg03488.html
This is the bare-minimum implementation for getting the API in
place prior to the 0.9.10 rc1 freeze; I can later do patches to
wire up the new optional argument to the qemu block_stream monitor
command to actually make use of the new base argument.
Eric Blake (3):
block rebase: add new API virDomainBlockRebase
block rebase: wire up remote protocol
block rebase: initial qemu implementation
