busy loop in libvirtd (cpu usage 100%)
Hi!
Occasionally of late, I've seen a few cases where libvirtd cpu usage
shoots up to 100% and stays there indefinitely. This seems to happen
when a QEMU VM is starting up, although on one occasion I *think* I
saw it happen after a QEMU VM was p2p-migrated.
Doing strace -f -p <libvirtd pid> reveals a flood of poll() functions calls
like these:

Re: libvirt-python Segfaults
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

How to specify the libvirtd in connect call
Hi,
Here is my situation, I install libvirt in a non-default directory
and start libvird with sudo. While I can connect virsh to libvirtd
using "virsh --connect qemu:///system", I fail to connect my app using
"virConnectOpen("qemu:///system")", which complains "unable to locate
libvirtd daemon in $PATH". Then, I take another try and add the path

Accessing libvirtd from multiple agents
Hi,
I was wondering if multiple remote agents can access the same libvirtd. How
do we prevent conflicting commands from the different agents. Can different
access permission be set for the agents? (The documentation usually goes
over the case where one agent can access multiple libvirtd and not this
case)
Thanks

How to tell if a hypervisor connection has died?
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 calls
yield an error number 1

Re: libvirtd error missing cpu model
Hi Andrea
Thanks for the help.
I debugged it myself.Actually the python API i.e nova-compute of openstack
cloud computing softwatre was looking for the cpu model through libvirt.I
made some changes in the application code and now I'm able to procees and
run the API successfully.

[libvirtd] qemu_process: reset CPU affinity to all enabled CPUs, when runs in custom cpuset
Hello All,
Since 4.5.0-23.el7 version (Red Hat 7.7), when I launch pinned VM,
libvirtd reset CPU affinity to all enabled in host CPUs, if it runs in
custom cpuset.
I can't reproduce this behavior with 4.5.0-10.el7_6.12 with the same
kernel version (Red Hat 7.7).
Libvirt runs in a custom cpuset 'libvirt', where the number of
available cpus is restricted to 0,2,4,6,8.
And this

How can openstack retrieve the CPU usage of a lxc via libvirt?
Dear all,
I want to have a view of lxc CPU usage in openstack Dashboard. According the Openstack official site , Openstack Ceilometer can poll libvirt daemon to obtain CPU usage of a virtual machine. I tried the command locally on the libvirtd host "virsh -c lxc:/// domjobinfo", I got an error "error: this function is not supported by the connection driver:

Libvirtd failed to start inside container: libvirt-qemu.so.0: cannot open shared object file: Permission denied
Hi all.
I run into trouble, while try to start libvirtd inside docker container
(actually it is LXC container).
During startup libvirtd can't load shared library libvirt-qemu.so.0 (and
strace results looks very odd).
* I run libvirtd as root.
* libvirt-bin - 0.9.8-2ubuntu17
* selinux/apparmor both disabled.
* No other security extension are used.
* No sticky bits are set.
