Description Richard W.M. Jones 2014-09-05 09:52:08 UTC 
Description of problem:

libvirt qemu:///session URLs are broken.  See the end of the build
log here:

http://download.devel.redhat.com/brewroot/work/tasks/2686/7922686/build.log

libvirt: XML-RPC error : Failed to connect socket to '/builddir/.cache/libvirt/libvirt-sock': No such file or directory
libguestfs: error: could not connect to libvirt (URI = qemu:///session): Failed to connect socket to '/builddir/.cache/libvirt/libvirt-sock': No such file or directory [code=38 domain=7]

Version-Release number of selected component (if applicable):

libvirt-devel-1.2.8-1.el7.x86_64

How reproducible:

100%

Steps to Reproduce:
1. Build libguestfs and run 'make quickcheck'
Comment 2 Richard W.M. Jones 2014-09-05 11:19:44 UTC 
I'm able to reproduce this using:

rm -rf /tmp/p
mkdir -p /tmp/p/.cache
killall libvirtd
export LIBVIRT_DEBUG=1
export HOME=/tmp/p
export XDG_RUNTIME_DIR=/tmp/p/.cache
libguestfs-test-tool

Note that /tmp/p/.cache/libvirt does not exist in this scenario.
I would have expected libvirt to create the directory if it does
not exist, but apparently it does not.

(You get the same error if /tmp/p/.cache doesn't exist too)

Downgrading to libvirt 1.1.1-29.el7 fixes the problem, therefore this
seems to be a regression between releases.
Comment 4 Jiri Denemark 2014-09-05 14:32:47 UTC 
Hmm, looks like another regression caused by the socket activation code. The socket is no longer created by libvirtd but it's created by the client and passed to the daemon as a file descriptor.
Comment 5 Richard W.M. Jones 2014-09-05 20:11:21 UTC 
FYI same thing is now happening in Rawhide, eg:

I can confirm this is a dup of Bug 927369, the issue is beaing dealt with in there (since it cause it as well).
