similar to: How to tell if a hypervisor connection has died?

Hey! I am trying to figure out how to reliably maintain a connection to libvirtd. From the documentation, I would expect something like that: - virConnectOpen() - virConnectRegisterCloseCallback() - virConnectSetKeepAlive() - Application logic And in the registered callback, I would: - virConnectUnregisterCloseCallback() - virConnectClose() - virConnectOpen() -

Hi In my program , When libvirtd restart , the old libvirtd connection(virConnectPtr) has to reconnect, Before usr old virConnectPtr , I call virConnectIsAlive. but when I restart libvirtd , virConnectIsAlive return 1, and I continue other operate use the old virConnectPtr, program will receive signal pipe. I use libvirt event. before any api use, I call virEventRegisterDefaultImpl, and

Hi Michal, virConnectOpen is for connecting to a host right..? I want to check the host status, whether the connection to the host is active or not.. for that purpose we have to use virConnectIsAlive() I'm using libvirt python bindings, here is the function defnintion. def isAlive(self): """Determine if the connection to the hypervisor is still alive A

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

Hi, Using libvirt how can we check the status of a remote/local host machine.. isAlive() method is giving true even if the internet connection is broken OR libvirt demon in the remote machine is being stopped. so isAlive() does not seems to be handy, Is there some other way to get the status of remote host..? Thanks -Sijo

Libvirt has a fixed 15 second timeout for qemu to exit. If qemu is writing to a slow USB key, it can hang (in D state) for much longer than this - many minutes usually. The solution is to check specifically for the libvirt EBUSY error when this happens, and retry the virDomainDestroyFlags operation (indefinitely). See also the description here:

Hi, I have noticed that virt-manager has the ability to show me the current cpu- and memory-usage of both the host and running guest machines. How does it do that? I could make good use of that information myself in the client applications I'm writing, however, from what I can see on http://libvirt.org/html/libvirt-libvirt.html, I have no idea how to go about getting it from libvirt.

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

Hi, After upgrading to libvirt 0.8.1, I can no longer create empty volumes with no backing store and an explicit format of qcow2. This XML volume definition: <volume> <name>testserverb-data2.img</name> <allocation>0</allocation> <capacity units='G'>20</capacity> <target> <format type='qcow2'/>

i am trying 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

Hi,everyone, there is a problem with libvirt support spice protocol. i use the following patch file,but it seems not success.anyone have an idea about that? thanks. patch file: This adds an element <graphics type='spice' port='5903' tlsPort='5904' listen='127.0.0.1'/> This is the bare minimum that should be exposed in the guest config for SPICE.

Hello I am trying to get libvirt-python working in Ubuntu 14.04 64 bit system.

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, 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, Sometimes when stopping a virtual domain using virDomainDestroy(), I come across a domain that is already stopped. (For example when someone already stopped the domain manually using virsh or because the guest OS issued a shutdown.) This is a special case that I absolutely need to catch and handle. Unfortunately, when this happens, and I call virGetLastError() afterwards, I always just
