[Libvir] Debian package structure

hello all, I have been worked in libvirt, virt-manager and virtinst packages to Debian for a weeks. Packages are now stabilized. Following below the /debian directories structure for analise. * libvirt: svn co http://svn.mussicorp.net/projetos/src/xen/libvirt/trunk/ * Virt-manager: svn co http://svn.mussicorp.net/projetos/src/xen/virt-manager/virt-manager/trunk/ * Virtinst: svn co http://svn.mussicorp.net/projetos/src/xen/virt-manager/virtinst/trunk/ Best regards, -- Marco Sinhoreli

[Libvir] Finally - fix the build on Debian
by Richard W.M. Jones 29 May '07

29 May '07

The attached patch fixes three separate build problems on Debian: (1) The libtool autoconf macro is wrong in that it requires a C++ compiler and /lib/cpp, neither of which seems to be really needed. (2) If you pass -fstack-protector while compiling, then you also need to pass it while linking, so that gcc knows to link -lssp. (3) Long-standing problem that xencapstest.c won't compile --without-xen. Well, OK so I didn't actually fix (1), but I did add a note to the TODO file pointing out the problem. So you'll still need to install the Debian "g++" package before you can compile libvirt.

[Libvir] [PATCH] Fix some memory leak

Hi This patch fixes some memory leak in libvirt. 1. The point that checks command-option in virsh.c 2. The point that checks version of Xen in xen_internal.c 3. The point that checks OS type of VM in xend_internal.c And these memory leaks can be checked by valgrind.

[Libvir] [PATCH] Add Python binding for virGetVersion

This patch adds a Python binding for the virGetVersion call (called libvirt.getVersion). $ python Python 2.4.4 (#1, Oct 23 2006, 13:58:18) [GCC 4.1.1 20061011 (Red Hat 4.1.1-30)] on linux2 Type "help", "copyright", "credits" or "license" for more information. >>> import libvirt; >>> libvirt.getVersion (None); (2002, 3000001) >>> libvirt.getVersion ("QEMU"); (2002, 2002) It also gives you a way to detect if a particular driver is compiled in, which I guess could be quite useful: >>> libvirt.getVersion ("not_here"); libvir: error : no support for hypervisor Traceback (most recent call last): File "<stdin>", line 1, in ?
