Yeah, probably some 'rpm -qV' (or whatever the command to verify all
packages is) could help as well.
"rpm -aV" didn't turn up anything obvious:
S.5....T. c /etc/libvirt/libvirtd.conf was modified for logging:

Is there a "how to" similar to [1] that lets one qemu to log that
it was
invoked and how far it got?
I removed qemu (dnf remote qemu; sudo dnf remove qemu-common)
build qemu 2.2-maint (assuming this relates to 2:2.7.1-6.fc25) from
github sources
installed qemu from sources (into /usr/local/bin)
Things are a bit better. Where something like "sudo virsh pool-list"
would just hang before, now my storage pools actually are listed. No
luck listing my VM's, but "virsh list" and "virsh list --all" do not
hang like before:
# virsh list
Are you sure you didn't miss the --all?
Yes I'm sure. I wish that was all it was <g>

VM xml is /etc/libvirt/qemu. The network, virbr0 is in
/etc/libvirt/qemu/networks, and that gets created just fine. All have
root:root owner:group:
The VMs are not visible because the XML cannot be parsed if the
binaries
are not on the system (the XML contains the whole path). Also, I think
this works because libvirt doesn't look into /usr/local/bin, but I
might
be wrong. Check whether 'virsh capabilities' tells you something
about
any emulator.
You can try installing from source, but putting it in /usr/bin,
I put qemu-system-x86_64 and qemu-x86_64 in /usr/bin as requested. No
luck. It seems /usr/local/bin/qemu-xxx is found (see CGroup: output)

So this is now only with the qemu from source installed on the system?
Correct.
Using qemu installed from source, I decided to try to create a VM. It
worked. I cut/pasted a script I used to create a centos72 VM, renamed
the name and cut the disk size down:
$ cat debug-centos.sh
#/bin/bash
sudo virt-install -n dbgcent72 \
--ram=4096 \
--vcpus 2 \
--disk path=/dev/vg_guest_images/dbgcent72,device=disk,size=5 \
--description "Centos 7.2 64Bit" \
--network bridge:brguest0,model=e1000 \
--cdrom /home/mcc/Downloads/CentOS-7-x86_64-DVD-1511.iso \
--vnc \
--noautoconsole \
--hvm \
--os-type=linux \
--os-variant centos7.0 \
--video=vmvga
$ ./debug-centos.sh
Starting install...
Domain installation still in progress. You can reconnect to
the console to complete the installation process.
$ sudo virsh list --all
