[libvirt] [PATCH RFC 0/5] add support for scsi-generic for virtio-scsi
by Han Cheng 21 Mar '13

21 Mar '13

This patch series tried to implement the fifth part of Paolo's proposal: http://permalink.gmane.org/gmane.comp.emulators.libvirt/50428 It is not completed. But it may for use. Needs some more works on: src/qemu/qemu_hostdev.c src/qemu/qemu_hotplug.c We may also need create src/util/virscsi.[hc] like src/util/vir(pci|usb).[hc], add sg* to nodedev tree and some others. As scsi hostdev needs -drive and -device like disk. There are two approaches: a) build a disk then use the disk related functions, b) create new function for it. I chose the last one as it is clearer and easier. But this may create some redundant codes. Any ideas?

[libvirt] [PATCH] Fix linkage of virt-aa-helper with numa library
by Daniel P. Berrange 21 Mar '13

21 Mar '13

From: "Daniel P. Berrange" <berrange(a)redhat.com> The recent commit moved some of the use of libnuma out of the driver code, and into src/util/. It did not, however, update libvirt_util.la to link against libnuma. This caused linkage failure with virt-aa-helper, since nothing else caused libnuma to be pulled onto the linker command line. The fix removes all reference to NUMACTL_LIBS/CFLAGS from the various modules in src/Makefile.am and just adds them to the libvirt_util.la module, which everything else depends on. Technically a build-breaker fix, but wanted to wait for feedback on this Signed-off-by: Daniel P.

[libvirt] [PATCH] python: fix about some of python binding APIs don't raise and exception
by Guannan Ren 21 Mar '13

21 Mar '13

For example: >>> dom.memoryStats() libvir: QEMU Driver error : Requested operation is not valid:\ domain is not running There are six such python API functions like so. The root reason is that generator.py script checks the type of return value of a python stub function defined in libvirt-api.xml or libvirt-override-api.xml to see whether adding the raise clause or not in python wrapper code in libvirt.py. The type of return value is supposed to be C types. For those stub functions which return python non-integer data type like string, list, tuple, dictionary, the existing type in functions varies from each other which leads problem like this. Currently, in generator.py, it maintains a buggy whitelist for stub functions returning a list type. I think it is easy to forget adding new function name in the whitelist. This patch makes the value of type consistent with C type "char *" in libvirt-override-api.xml. For python, any of types could be printed as string, so I choose "char *"in this case. And the comment in xml could explain it when adding new function definition. <function name='virNodeGetCPUStats' file='python'> ... - <return type='virNodeCPUStats' info='...'/> + <return type='char *' info='...'/> ... </function> --- python/generator.py | 10 ++-- python/libvirt-override-api.xml | 116 +++++++++++++++++++++------------------- 2 files changed, 66 insertions(+), 60 deletions(-) diff --git a/python/generator.py b/python/generator.py index 8236bd2..bebc644 100755 --- a/python/generator.py +++ b/python/generator.py @@ -1008,11 +1008,9 @@ functions_list_exception_test = { } functions_list_default_test = "%s is None" -def is_list_type (name): - whitelist = [ "virDomainBlockStats", - "virDomainInterfaceStats" ] +def is_python_noninteger_type (name): - return name[-1:] == "*" or name in whitelist + return name[-1:] == "*" def nameFixup(name, classe, type, file): # avoid a desastrous clash @@ -1386,7 +1384,7 @@ def buildWrappers(module): ("ret", name)) classes.write(" return ret\n") - elif is_list_type (ret[0]): + elif is_python_noninteger_type (ret[0]): if not functions_noexcept.has_key (name): if functions_list_exception_test.has_key (name): test = functions_list_exception_test[name] @@ -1656,7 +1654,7 @@ def buildWrappers(module): classes.write (" return ret\n") - elif is_list_type (ret[0]): + elif is_python_noninteger_type (ret[0]): if not functions_noexcept.has_key (name): if functions_list_exception_test.has_key (name): test = functions_list_exception_test[name] diff --git a/python/libvirt-override-api.xml b/python/libvirt-override-api.xml index 5976fb2..6087f86 100644 --- a/python/libvirt-override-api.xml +++ b/python/libvirt-override-api.xml @@ -1,5 +1,13 @@ <?xml version="1.0"?> <api name='libvir-python'> +  <symbols> <function name="virConnectGetVersion" file='python'> <info>Returns the running hypervisor version of the connection host</info> @@ -14,34 +22,34 @@ <function name="virConnectListDomainsID" file='python'> <info>Returns the list of the ID of the domains on the hypervisor</info> <arg name='conn' type='virConnectPtr' info='pointer to the hypervisor connection'/> - <return type='int *' info="the list of ID or None in case of error"/> + <return type='char *' info="the list of ID or None in case of error"/> </function> <function name='virConnectListDefinedDomains' file='python'> <info>list the defined domains, stores the pointers to the names in @names</info> <arg name='conn' type='virConnectPtr' info='pointer to the hypervisor connection'/> - <return type='str *' info='the list of Names or None in case of error'/> + <return type='char *' info='the list of Names or None in case of error'/> </function> <function name='virConnectListAllDomains' file='python'> <info>returns list of all defined domains</info> <arg name='conn' type='virConnectPtr' info='pointer to the hypervisor connection'/> <arg name='flags' type='unsigned int' info='optional flags'/> - <return type='domain *' info='the list of domains or None in case of error'/> + <return type='char *' info='the list of domains or None in case of error'/> </function> <function name='virConnectListNetworks' file='python'> <info>list the networks, stores the pointers to the names in @names</info> <arg name='conn' type='virConnectPtr' info='pointer to the hypervisor connection'/> - <return type='str *' info='the list of Names or None in case of error'/> + <return type='char *' info='the list of Names or None in case of error'/> </function> <function name='virConnectListDefinedNetworks' file='python'> <info>list the defined networks, stores the pointers to the names in @names</info> <arg name='conn' type='virConnectPtr' info='pointer to the hypervisor connection'/> - <return type='str *' info='the list of Names or None in case of error'/> + <return type='char *' info='the list of Names or None in case of error'/> </function> <function name='virConnectListAllNetworks' file='python'> <info>returns list of all networks</info> <arg name='conn' type='virConnectPtr' info='pointer to the hypervisor connection'/> <arg name='flags' type='unsigned int' info='optional flags'/> - <return type='network *' info='the list of networks or None in case of error'/> + <return type='char *' info='the list of networks or None in case of error'/> </function> <function name='virDomainLookupByUUID' file='python'> <info>Try to lookup a domain on the given hypervisor based on its UUID.</info> @@ -57,54 +65,54 @@ </function> <function name='virDomainGetInfo' file='python'> <info>Extract information about a domain.
