[libvirt] How to connect to a remote VM ESXi server with Python language?
by ice 30 Dec '11

30 Dec '11

Hi, Dear Mr/Mrs. I have trouble in connecting to a VM ESXi server with python. I am a developer using libvirt to control remote VM ESXi with python language. But I am not able to connect to a remote VM ESXi server. I make my try to solve this issue: 1: I use the function libvirt.Open() to open the remote VM ESXi Server, but I don't know how to input the password. It seems that there is no parameter for password input. 2: I use "virsh connect ---". It is succeed when it is executed on locale machine manual, but failed when I invoke this command in python environment. I use "subprocess.Popen" to execute the command "virsh", but this function would be hung on after command "communicate" executed. -bash-4.1# python Python 2.6.6 (r266:84292, May 20 2011, 16:42:11) [GCC 4.4.5 20110214 (Red Hat 4.4.5-6)] on linux2 Type "help", "copyright", "credits" or "license" for more information. >>> from subprocess import Popen,PIPE,STDOUT >>> command=['virsh', '-c', 'esx://192.168.58.144/?no_verify=1','list', '--all'] >>> p=Popen(command, stdin=PIPE,stdout=PIPE, stderr=STDOUT) >>> output = p.communicate()[0] How to fix it? Thanks for help! Best regards!

From: Alex Jia <ajia(a)redhat.com> python: Fixup python binding for virDomain{Set, Get}BlockIoTune APIs The parameter 'params' is useless for virDomainGetBlockIoTune API, and the return value should be a string not integer. In addition, the parameter number is also incorrect in libvirt_virDomain{Set, Get}BlockIoTune APIs. * libvirt-override-api.xml: Remove useless the parameter 'params' from virDomainGetBlockIoTune API, and change return value type from integer to string. * python/libvirt-override.c: Fix the parameter number match issue. https://bugzilla.redhat.com/show_bug.cgi?id=770683 Signed-off-by: Alex Jia <ajia(a)redhat.com> --- python/libvirt-override-api.xml | 3 +-- python/libvirt-override.c | 4 ++-- 2 files changed, 3 insertions(+), 4 deletions(-) diff --git a/python/libvirt-override-api.xml b/python/libvirt-override-api.xml index 07e4a78..a2fd219 100644 --- a/python/libvirt-override-api.xml +++ b/python/libvirt-override-api.xml @@ -401,9 +401,8 @@ <info>Get the I/O tunables for a block device</info> <arg name='dom' type='virDomainPtr' info='pointer to the domain'/> <arg name='disk' type='const char *' info='disk name'/> - <arg name='params' type='virTypedParameterPtr' info='Pointer to blkio tuning params object'/> <arg name='flags' type='unsigned int' info='an OR'ed set of virDomainModificationImpact'/> - <return type='int' info='0 in case of success, -1 in case of failure'/> + <return type='char *' info='the I/O tunables value or None in case of error'/> </function> <function name='virDomainBlockPeek' file='python'> <info>Read the contents of domain's disk device</info> diff --git a/python/libvirt-override.c b/python/libvirt-override.c index 8a643a3..a704e78 100644 --- a/python/libvirt-override.c +++ b/python/libvirt-override.c @@ -3301,7 +3301,7 @@ libvirt_virDomainSetBlockIoTune(PyObject *self ATTRIBUTE_UNUSED, int nparams = 0, i; int c_ret; - if (!PyArg_ParseTuple(args, (char *)"Ozi:virDomainSetBlockIoTune", + if (!PyArg_ParseTuple(args, (char *)"OzOi:virDomainSetBlockIoTune", &pyobj_domain, &disk, &pyinfo, &flags)) return(NULL); domain = (virDomainPtr) PyvirDomain_Get(pyobj_domain); @@ -3395,7 +3395,7 @@ libvirt_virDomainGetBlockIoTune(PyObject *self ATTRIBUTE_UNUSED, virTypedParameterPtr params; int c_ret; - if (!PyArg_ParseTuple(args, (char *)"Oi:virDomainGetBlockIoTune", + if (!PyArg_ParseTuple(args, (char *)"Ozi:virDomainGetBlockIoTune", &pyobj_domain, &disk, &flags)) return(NULL); domain = (virDomainPtr) PyvirDomain_Get(pyobj_domain); -- 1.7.1
