Hi,
I am just trying to use libvirt storage api from python terminal, and i am
getting the following error.
>>> import libvirt

I got fed up trying to figure out how to fix the coverage reports to merge
data from multiple runs correctly, so this patch rips out all our test
coverage support. In its place is a makefile rule which just calls out to
the lcov program. It requires lcov >= 1.6 since earlier versions were
too dum

This fixes the sole remaining leak exposed by "make check" vs. valgrind.
Actually it fixes two leaks, but the duplicate sound string one
isn't triggered by the tests.

Hi,
I am getting the above said runtime error (libvir: Remote error : unknown
procedure: 72) when I ran a program using the api virConnectListStoragePools. I
googled but I could not get any solution. Please help me solve the issue.
Thanks and Regards,
Amudhan.

ACK. I've just noticed the QEMU driver does ever fill in the dom
or net fields at all, and we know the remote driver doesn't either.

This is a pair of patches which deprecate the conn, dom and net fields
in the virterror structure.
Programs which use these fields will get a warning (if compiled under
gcc anyway):
foo.c:123: warning: 'dom' is deprecated (declared at
/usr/include/libvirt/virterror.h:81)

This switches over a number of the test cases to make use of the new
virTestMain() function and thus gain support for allocation checking
So you can now actually see some checks when running

The capabilities.c file was not checking for NULL pointers when cleaning
up after some failed allocations, and so deferencing a NULL.
The qparams.c file was not calling virRaiseError upon failure so there
wasn't any indication of why it failed
The qemu_conf.c file was not free'ing the sound card
This patch adds more helper functions to the tests/testutils.c file which
make it trivial to verify OOM handling in our test suites.
It provides a virtTestMain() function which is the main driver. This is
given the original argc, argv and a function callback representing the
test suite to run. N

This patch adds extra code to src/memory.c which allows us to force an OOM
condition on specific allocations. This is not code you *ever* want to use
in a production build, so its all conditional on TEST_OOM, which is enabled
by passing --enable-test-oom to the configure script.
The hooks work as
The following series of patches add infrastructure neccessary to let us test
OOM handling for any libvirt code using our malloc wrappers. Currently only
a few places use this, but as this series will show, it already lets us find
several bugs. As we convert more code away from malloc to VIR_MALLOC

Anyway, it's not possible with libvirt, but in general Linux you can

Daniel pointed out that the way we build up the QEMU argv strnig is becoming
rather unscalable / error prone. This patch refactors it into to use a short
macro to do memory allocation/reallocation, which clears it up quite nicely

Hi,
I have got the problem solved. I could now compile the code using Storage APIs
also. But I run them I am getting error message: "libvir: Remote error :
unknown procedure: 72"
The API I used is: virConnectListStoragePools
What is the problem here? How could I solve this. My OS is SLES 10 sp

It sounds a bit Xen specific, but I see no reason why this should not be
