Don't add things to xenUnifiedDriver structure -- this structure should
go away eventually. (See the comment in src/xen_unified.h).
Instead, just do whatever you need directly from src/xen_unified.c, be
that direct code or calling something lower level.

You should send any questions to libvirt-list:

[Libvir] libvirt & vde_switch
by Loic Dachary
In reply to
http://www.redhat.com/archives/libvir-list/2007-April/msg00177.html
an area where vde_switch support is usefull is an unprivileged user
running tests. A test suite involving the creation of qemu instances
thru libvirt should not be forced to create a bridge or alter the
iptables configuration. With vde_switch and slirpvde multiple qemu
instances can be run without altering the network configuration of the host.
I hope it helps.
Cheers

[Libvir] mark some diagnostics for translation
by Jim Meyering
This makes it so some diagnostics emitted via the error function
are checked for use of "_(...)" when you run "make syntax-check",
and fixes the ones that lacked that:
Enable the sc_unmarked_diagnostics test and correct all violations
involving the "error" function.
* Makefile.cfg (local-checks-to-skip): Remove from skip list.
Then, at the end, a second patch:
Mark a string for translation.
* src/virsh.c: Add a "%s" and wrap with _(...).
Note that technically, it doesn't make sense to translate
a diagnostic like this (there are several like this):
error (conn, VIR_ERR_RPC, _("maxids > REMOTE_DOMAIN_ID_LIST_MAX"));
However, if it's worth emitting the diagnostic, then I think it's worth
making it a little more useful to someone not reading the code, e.g.,
too many domains (maximum is %d)
If no one objects, I'll convert the ones below.

[Libvir] mark more translatable messages
by Jim Meyering
This change marks for translation some more messages.
It adds a few new ones, too, e.g., replacing "domain" with
_("failed to parse domain description") in two places.
Likewise, there are some like this:
- virXendError (conn, VIR_ERR_NO_MEMORY, "strdup");
+ virXendError (conn, VIR_ERR_NO_MEMORY, _("strdup failed"));
The two new grep invocations in Makefile.maint handle two situations:
First, when the entire statement is on a single line (ends in ";").
The second grep (with -A1) is to get the diagnostics that appear
on the line following the function name. Hence where the first line
ends in ",". With checks like this, it's nice if you can assume no
trailing blanks in the code base. IMHO, that would be a nice change
to make soon, but it's more invasive.
Enable more checks for unmarked messages; fix violators.
* Makefile.maint (sc_unmarked_diagnostics): Check for more functions.
* src/conf.c (virConfParseValue): Remove trailing space in diagnostic.
* src/libvirt.c (do_open, virDomainMigrate): Mark diagnostics.
* src/xend_internal.c (do_connect, xenDaemonDomainDumpXMLByID): Likewise.
(xenDaemonDomainDumpXMLByName, xenDaemonCreateLinux): Likewise.
(xenDaemonDomainMigratePerform, xenDaemonDomainDefineXML): Likewise.
* src/xml.c (virXPathString, virXPathNumber, virXPathLong): Likewise.
(virXPathBoolean, virXPathNode, virXPathNodeSet): Likewise.
(virDomainParseXMLOSDescHVM): Likewise.
* src/xmlrpc.c (xmlRpcValueNew): Likewise.
(xmlRpcValueUnmarshalDictElement): Likewise.

[Libvir] virsh vncdisplay fix
by John Levon
I have an old HVM guest defined in 3.0.4, and now I'm running 3.1.2 and
libvirt 0.4.0. The config looks like this:
(domain
(image
(hvm
(vnc 1)
(vncdisplay 0)
(device
(vfb
(location localhost:5900)
(vncdisplay 0)
(uuid ...)
The libvirt code looks like this:
1757 /* Graphics device (HVM <= 3.0.4, or PV <= 3.0.3) vnc config */
1758 if ((hvm && xendConfigVersion < 4) ||
1759 (!hvm && xendConfigVersion < 3)) {
1760 tmp = sexpr_fmt_node(root, "domain/image/%s/vnc", hvm ? "hvm" : "linux");
So we don't see the 'vnc 1' at the top. But the code to parse device/vfb doesn't
expect this config either:
1685 tmp = sexpr_node(node, "device/vfb/type");
The patch below replaces the later version check with something that
copes correctly with the "upgrade" case.

[Libvir] [PATCH] Pull vc-list-files from gnulib, and update.
by Jim Meyering
Now that I've added the vc-list-files script to gnulib,
this patch makes libvirt's bootstrap pull it from there.
Changes from the previous version of the script:
I reintroduced support for mercurial (only lightly tested),
and rearranged the directory-existence tests so git is first.
Here's the full patch, including a renaming in vasnprintf.c:
----------------
Pull vc-list-files from gnulib, and update.
* bootstrap (gnulib_tool): Add the vc-list-files module.

[Libvir] libvirt.c: avoid a double-free upon do_open failure

the testing framework) domains, I got a double-free error:

At first, rather than removing the offending
free, I inserted this line just after it:
ret->name = NULL;
which avoids leaking ->name even if some driver-specific close function
fails to clean up properly. But IMHO if such a function doesn't clean
up properly then *it* should be fixed, not all callers.
