HI, I am using ubuntu host machine and KVM is present as guest in that machine.Two virtual machines are there.I am using Python binding to query on the hypervisor and extract the VM related information. Here is my simple code: #!/*usr*/local/bin/*python * import libvirt import sys conn = libvirt.openReadOnly(None) if conn == None: print *'Failed to open connection to the

Hi , I have two KVM guests in ubuntu host machine.I am using Python binding of Libvirt API to query on the hypervisor and capture the CPU , memory related information of the guest machines. I need to capture the detail information regarding CPU like : cpu_aidle, cpu_idle, cpu_speed, cpu_wio and memory like :mem_cached,mem_buffers,mem_free etc. of the guest machines. How could I get these

I have a python script that monitors the guest VMs on a servers running Xen, but the script doesn't work properly on a server I just built with KVM. The script runs as a non-root user (same on all servers) and simply gathers some details on the status and names of the domains running on the host. The Xen and KVM servers are running CentOS 5.4 x86_64 and are using the same version of

Hi , I am using ubuntu host machine and KVM is present as guest in that machine.Two virtual machines are there.I am using Python binding to query on the hypervisor and extract the VM related information.I like to print memory stat of the VM like SWAP_IN , SWAP_OUT,free memory, mem cached etc.So, the code, I have written for this, is : #!/usr/local/bin/python import libvirt import sys conn =

I am using cent OS 6.7 andI have installed omnet++ 4.6 on it.When I am trying to create a new omnet++ project then suddenly omnet++ window is terminating and an error message is showing as "A problem in the Java-1.7.0-openjdk-1..7.0.85-2.6.1.3el6_7package has been detected".Then I uninstalled this version of java and tried with version "1.7.0_91" and "1.7.0_79" but

Hi Harish, I believe the proper establishment of a connection should be done by libvirt.open() or libvirt.openAuth() or libvirt.openReadOnly(). All of them will return a functional virConnect instance. I'm not sure this segfault is worth to fix since instantiate a virConnect directly is not an expected usage. Hope this information will help you. Best Regards, Hao Liu +86-010-62608262

Hi, I am doing some domain resource monitoring work. I use cat /dev/urandom | md5sum to simulate vCPU load and write a script to calculate vCPU utilization. It seems all good at the beginning. After I abort the ``cat ... md5sum`` command in domain, I see some strange data as below: CPU time: 8410960000000 CPU util: 99.8410609331% CPU time: 8411970000000 CPU util: 100.843672381% CPU time:

I was getting vCPU use time outside of guest with libvirt-python API, and them calculate utilization with (cpuTime2 - cpuTime1) / (t2 - t1).

Hello, everyone! I installed xen3.2.0 on Ubuntu and meet some problem.

Hi, I can''t seem to get libvirtd to accept remote connections. Both systems are built using genunix''s b130. It seems that connections originating from the xvm0 server itself are fine but as soon as I go on to the other box and run the same python script (or simply virsh) the connection gets dropped immediately. Telnetting to port 16509 confirms that it drops the connection

I have a few different groupings of hosts, and I am wondering what is the best way to organize the node configuration for them. I have a few machines that are VMware hosts, a bunch of VMware guests, and the main admin server which runs a bunch of stuff like puppetmasterd. I''ve got a bunch of classes/*.pp which define configuration for sudo, yum, java, etc. Right now I just have

Hi, I am trying to connect to libvirt on KVM host from a remote python client, using the connection string "qemu+ssh://<IP Address>/system" If I setup password less SSH (Public key) between the machines, I am able to proceed with the connection. But If I have not setup the public key authentication, my code hangs trying to connect to libvirt, and there is a prompt for entering
