hi, i am a bit confused on how to start an inactive domain using the python bindings, any help would be appreciated. (inactive as in the domain was created with?virConnect.defineXML sometime in the past) looks like i have to use virDomain.create, however virDomain.create needs a defined domain xmldesc as a parameter and i am not sure on how to get that i guess if?virConnect.create was happening right after?virConnect.defineXML i could get the return value of?virCo...

i am trying to list active + defined and inactive + defined domains using libvirt 0.9.4 i can get active domains using: def s_activedomains(conn): #get active domain ids numofdomains=libvirt.virConnect.numOfDomains(conn) activedomains=libvirt.virConnect.listDomainsID(conn) return activedomains i am stuck on how to get inactive domains the example listed here?http://libvirt.org/guide/html/Application_Development_Guide-Guest_Domains-Listing.html under example 4.4 and example 4.5 seems to be outda...

...ng to get the free memory on a hypervisor using libvert, with the python api bindings as per?http://libvirt.org/python.html, it should be pretty easy, however the below is failing: #conn is a connection object freemem=libvirt.virNode.getFreeMemory(conn) although this works fine: software=libvirt.virConnect.getType(conn) if software == ?'QEMU': logging.debug('hypervisor is type QEMU')

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 ----- Original Message ----- > From: "Harish Vishwanath" <harish.shastry@gmail...

hi, how do i list storage pools and volumes using the python bindings? basically the python api calls for?virsh pool-list and virsh vol-list thanks

Hi, What's the best way to tell if a virConnect object is not good to use anymore? (For example because the libvirtd on the other side crashed/has been stopped or because of some network failure) When I try this, the first API call I do on a broken connection yields an error with error number 38 (VIR_ERR_SYSTEM_ERROR) and all subsequent call...

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

...ound that the libvirtd may cost 30% or above cpu time. Is it normal in my case? I tried to reduce this cpu consumption and found some variable in libvirtd.conf and got a little confused by variables like max_clients, max_workers, max_requests. In my opinion, max_clients limits the number of virConnect created by app. max_workers limits the number of thread to handle requests from clients. Does that mean requests from one client may be handled in multi-thread way if max_workers is greater than max_workers? max_request limits the concurrent RPC calls according the comments in libvirtd.conf...
