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, This is Arpita. I am using Libvirt API in the Windows Vista system.VMware is installed over there.I have installed Libvirt and Python 2.6 in the Windows Vista system andhave written a small test file in Python. Here is the code: import libvirt* * import sys conn = libvirt.openReadOnly(None) if conn == None: print *'Failed to open connection to the hypervisor' * sys.exit(1)

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 have a code : import libvirt con = libvirt.openReadOnly(None) print con.listDomainsID() When i run the above code using root i get the proper output... but when i use non-root user it givers be a empty list [ ] If i change the 2nd line to con = libvirt.open(qemu:///system) It works.

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

Hello, I'm trying to get memory usage statistic inside a guest machine using virDomainMemoryStats function at libvirt. According to http://libvirt.org/html/libvirt-libvirt.html#virDomainMemoryStatTags the structure could have a lot of useful memory statistic but the amount of parameters depends on the hypervisor and the driver. However using KVM I'm able to get

Hello, everyone! I installed xen3.2.0 on Ubuntu and meet some problem. After the following commands make all make linux-2.6-xen0-config CONFIGMODE=menuconfig make linux-2.6-xen0-build make linux-2.6-xen0-install I got xen-3.2.0.gz vmlinuz-2.6.18.8-xen0 etc. and put them to /boot, then I modified the menu.lst title Xen 3.2.0 / Ubuntu 8.04, kernel 2.6.18.8-xen0 root (hd0,8) kernel

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

Hello, I am using python bindings of libvirt. When I use the function listDomainsID( ) it successfully returns me the list of the ids of my current virtual machines, but when I call function listDefinedDomains( ) it returns me an empty list. Is this some kind of bug because as per my understanding listDefinedDomains should return a superset of vm's as returned by listDefinedDomains(). I am

how do i print the features of a domain from functions that return a domain object? for instance mydomain =?virdomain=libvirt.virConnect.lookupByID(conn,domainid) so mydomain is?virDomainPtr, which is?typedef virDomain * virDomainPtr i am not sure on how to print the domain object features in python, such as name, disk size, etc

hi experts: I am a freshman of libvirt, I have got a domU's info like: libvirt.open, lookupByID, info. But now I want to use libvirt to get a xen domU 's cpu usage ratio , how can I fulfill it ? I cannot find the API. -------------- next part -------------- An HTML attachment was scrubbed... URL:
