Description of problem:

Just updated F23 to F24, so libvirt upgraded from 1.2 to 1.3.  I have been using a couple of work VMs on this system, both under the qemu:///session connection.

When I try to start a guest, I get this error:

error: Failed to start domain <name>
error: Failed to connect socket to '/run/user/1000/libvirt/virtlogd-sock': Connection refused

I can work around this by manually running virtlogd (will probably write a user unit file, if I can figure that out, so I don't have to remember to do that every time)

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

1.3.3.1-4.fc24

How reproducible:

every time

Steps to Reproduce:
1. Start a qemu:///session guest
2. Guests fail to start with the error above

Actual results:

Requires workaround: manually run virtlogd

Expected results:

This is a regression, previously (under 1.2, so presumably no virtlogd dependency) no such workaround was necessary.

Additional info:

There is actually one more stumbling block (an apparent capabilities problem) which I have to work around before the guest can start.  Once I have that bug entered I'll cross-reference both of them.
