virInitialize dumps core intermittently.
Hi,
I have a host with 6 VMs set to autostart. When this host reboots, it
starts libvirtd, pegasus cimom and libvirt-cim. It also restarts the VMs.
Intermittently we noticed a core during start up that points to the last
call made by libvirt-cim to "virInitialize". I am thinking that it is a
timing issue where virInitialize is called while libvirt is trying to
autostart the VMs.

virConnectOpen question.
Hi,
I am using virConnectOpen(const char *uri) to connect to the local
hypervisor. When uri is set to "lxc:///", an error gets logged
in /var/log/messages about failed connection. But I do not see any error
for "xen:///". The machine does not have these drivers installed, and I am
using libvirt 0.6.3. My questions are -
1. Why I see error in /var/log/messages for container

Lifecycle of a connection to libvirtd
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()

issue with virErrorInitialize
One of my team mate investigated the issue where libvirt-cim was
segfaulting when unloading providers. More info on this issue is at
https://www.redhat.com/archives/libvirt-users/2011-August/msg00069.html
Here is the gist of his investigation -

Detecting the last user of a connection has closed.
The documentation says something that concerns me:
http://libvirt.org/html/libvirt-libvirt.html#virConnectClose
"It is possible for the last
virConnectClose<http://libvirt.org/html/libvirt-libvirt.html#virConnectClose>to
return a positive value if some
other object still has a temporary reference to the connection, but

application should not try to further use

question regarding CMPIObjectPath
Folks,
I'm a new user and I'm trying to build a standalone application using
libvirt-cim (rather than use a full-fledged CIMOM). I need some help.
While calling the CMPIInstanceMI->ft->enumerateInstances, I need to pass a
reference to CMPIObjectPath. My application is crashing because I don't
know what is the correct constructor for this. If I do ref = CMPIObjectPath

It seems that if I close a connection while a domain event callback is

[PATCH] RFC: v2v: add and use libvirt connection objects
Enhance the Libvirt_utils module with libvirt connection objects,
and read-only and read-writen open functions for them; adapt the rest of
the mini-binding to use these objects, instead of opening + closing
libvirt connections every time. This has different improvements:
a) a libvirt connection is reused for different API calls, improving
the communication with remote (input) servers
b)
