[Libvir] [PATCH] typo
by Atsushi SAKAI
Hi,
I finally succeed for building libvirt on windows(MinGW/MSYS).
Thank you for coopration.
During that work I found several typo in libvirt document.
Thanks

[Libvir] VIR_DOMAIN_NOSTATE
by Russ Blaine
On Solaris-based xen 3.1.2 I am seeing virDomainGetInfo() often returning
VIR_DOMAIN_NOSTATE in dominfo.state for domUs that are powered on and
running. What exactly does VIR_DOMAIN_NOSTATE mean? Why does it exist? I
suspect it is a catch-all in the API for hosts that don't entirely have
their act together, that do not always return a valid guest state. Is that
the case?
Is anyone else seeing this on Xen?

[Libvir] PATCH: Fix block device numbers for virDomainBlockStats
by Daniel P. Berrange
As mentioned in this thread:
http://www.redhat.com/archives/libvir-list/2008-January/msg00475.html
The code for calculating block devices numbers has a number of flaws.
This patch fixes the flaws and adds a comprehensive test program to
validate it. The test program also validates invalid cases.
NB, this code is actually now more perfect than Xen, since Xen doesn't
handle SCSI disks > sdp, even though you can go all the way to sdhv.
The rules are:
* hdNM: N=a-t, M=1-63, major={IDE0_MAJOR -> IDE9_MAJOR}
* sdNM: N=a-z,aa-hw, M=1-15, major={SCSI_DISK0_MAJOR -> SCSI_DISK15_MAJOR}
* xvdNM: N=a-p, M=1-15, major=XENVBD_MAJOR
Which translates to the formulas
xvdNM: (XENVBD_MAJOR * 256) + (disk * 16) + part;
sdNM: (majors[disk/16] * 256) + ((disk%16) * 16) + part
hdNM: (majors[disk/2] * 256) + ((disk % 2) * 63) + part;
The SCSI/IDE formulas lookup the major number in a table since
they are allocated non-contigously.
The test case validates these:
$ ./statstest

/dev/xvd == -1 OK
/dev/xvda == 51712 OK

The patch also fixes a couple of error codes to be INTERNAL_ERROR rather
than NO_SUPPORT, because the latter is for APIs which are not supported,
where as the conditions here are simply errors that shouldn't happen.
Dan.

[Libvir] update after changing XML
by Maxwell Bottiger
Hi,
I changed some of the XML for a qemu virtual machine. The original
file was generated by virt-manager, but I wanted to use bridged
networking as described in the documentation on the libvirt website. Is
there something I need to for my xml changes to show up in the virtual
machine? Right now my VM will not start because it's looking for it's
old network configuration.

[Libvir] [PATCH] virtinst: don't expect non-root users to have block device access
by Guido Guenther
Hi,
attached patch drops the assumption that a non-root user has read access
to the guest OSes partition - he doesn't need to since all interaction
is handled via libvirt and giving the user read access for a simple MBR
block read test seems like overkill. Please apply if appropriate, patch
is against current hg.
Cheers,
-- Guido

[Libvir] [PATCH] Avoid link errors with "configure --disable-shared".
by Jim Meyering
I tried to build static binaries in the usual libtool way,
via "configure --disable-shared" and got some link errors
due to the tests linking only with shared-lib-related files.
Here's the fix:
Avoid link errors with "configure --disable-shared".
* tests/Makefile.am (LDADDS): Add ../src/libvirt.la, so that
"configure --disable-shared" no longer provokes link errors.

[Libvir] 2/8 Add framework for code style- and syntax-checking rules.
by Jim Meyering
Add framework for code style- and syntax-checking rules.
Almost all tests are initially disabled via the list in Makefile.cfg.
* Makefile.am (EXTRA_DIST): Add .x-sc_avoid_if_before_free.
Omit names of files that automake includes automatically.
* .x-sc_avoid_if_before_free: New file.
* build-aux/vc-list-files: Likewise.
* build-aux/find-unnecessary-if-before-free: Likewise.
* GNUmakefile, Makefile.cfg, Makefile.maint: New files.

[Libvir] [PATCH] Plug test-related leaks
by Jim Meyering
Once I had a static "virsh" binary, I ran this:
cd src && valgrind --leak-check=full ./virsh --connect \
test://$PWD/../docs/testnode.xml list
which exposed some leaks.
I fixed them like this:
Plug test-related leaks.
* src/test.c (testLoadNetwork): Free forwardDev.
(testLoadDomain): Free ctxt.
(testLoadNetwork): Likewise.
(testOpenFromFile): Likewise.
