[libvirt] [PATCH] virsh-nodedev: Avoid spurious errors
by Michal Privoznik
Our public free functions explicitly don't accept NULL pointers
(sigh). Therefore, callers must do something like this:
if (dev)
virNodeDeviceFree(dev);
And we are not doing that on two places I've found. This leads to
dummy error message thrown by virsh:
virsh # nodedev-dumpxml nonexistent-device
error: Could not find matching device 'nonexistent-device'
error: invalid node device pointer in virNodeDeviceFree

[libvirt] [libvirt-php] libvirt_domain_new Create a slow vm
by Mario Di Ture
Hi,
I've tested this script on centos 6.5 (libvirt-0.10.2, qemu-kvm-0.12.1.2)
and
ubuntu server 14.04 (libvirt 1.2.2, qemu-kvm 2.0.0) with the same result.
The created vm is very slow compared to the vm created with virt-manager,
with the same features/devices on the same host.
Can you suggest any configuration that can avoid that slowness?
With regards
Mario D.

[libvirt] [PATCH] Don't use AI_ADDRCONFIG when binding to wildcard addresses
by Ján Tomko
https://bugzilla.redhat.com/show_bug.cgi?id=1098659
With parallel boot, network addresses might not yet be assigned [1],
but binding to wildcard addresses should work.
For non-wildcard addresses, ADDRCONFIG is still used. Document this
in libvirtd.conf.

[libvirt] [PATCH] leaseshelper: Include locale.h
by Michal Privoznik
The commit baafe668 introduces this new helper utility. As in all
our programs, there's setlocale() called at the beginning of
main(). However, this source file don't include locale.h file
which causes build errors on some systems (e.g. mine).

[libvirt] Bug: iohelper drops I/O error messages
by Jason J. Herne
During a recent managed save operation I received the following error
message:
error: operation failed: domain save job: unexpectedly failed.
It turns out that I had run out of disk space. After a brief investigation I
discovered that libvirt_iohelper is exec'ed and is used to handle all
I/O during
a (Qemu) managed save operation. While iohelper appears to be set up to log
error conditions when they occur, for some reason the logging is getting
lost.
I'm hoping someone can help figure out why these errors are getting lost. It
would be nice to present a useful error message to the user when a
managed save
fails because of an I/O error.
