[libvirt] How to connect to a remote VM ESXi server with Python language?
by ice 29 Dec '11

29 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!

[libvirt] [PATCH] Fix build on s390(x) and other stange arches

[libvirt] [PATCHv3 0/6] Add new command domiftune
by Hu Tao 28 Dec '11

28 Dec '11

This series adds a new command domiftune to get/set parameters of domain's network interfaces. Supported parameters are bandwidth settings. Currently the network interface bandwidth can only be set: - in domain's xml before the domain is up - when attaching an interface by attach-interface With this series, users can change network interface bandwidth settings using virsh, whether the domain is running or not. changes: - fix some typos - improvements on docs - use virDomainLiveConfigHelperMethod - some improvements in qemu_driver Hu Tao (6): Add API virDomain{S,G}etInterfaceParameters virDomain{S,G}etInterfaceParameters: the main entry points Add virDomain{S,G}etInterfaceparameters support to the remote driver Add a function virDomainFindNetDef Add virDomain{S,G}etInterfaceParameters support to qemu driver Enable the virDomain{S,G}etInterfaceParameters in virsh daemon/remote.c | 64 ++++++++ include/libvirt/libvirt.h.in | 50 ++++++ python/generator.py | 2 + src/conf/domain_conf.c | 39 +++++ src/conf/domain_conf.h | 3 + src/driver.h | 12 ++ src/libvirt.c | 129 ++++++++++++++++ src/libvirt_private.syms | 1 + src/libvirt_public.syms | 2 + src/qemu/qemu_driver.c | 337 ++++++++++++++++++++++++++++++++++++++++++ src/remote/remote_driver.c | 52 +++++++ src/remote/remote_protocol.x | 28 ++++- src/remote_protocol-structs | 24 +++ tools/virsh.c | 198 +++++++++++++++++++++++++ tools/virsh.pod | 21 +++ 15 files changed, 961 insertions(+), 1 deletions(-) -- 1.7.4.4
