[libvirt-users] Libvirtd freezes

[Stefano Ricci]

Hello everyone
I come back to ask for a hand to solve a problem that has affected me
since October 2016 and I have not yet solved using libvirt.
I thought I would solve it by going to a 4.9.x kernel with qemu
2.8.1.1 and with libvirt 3.2.0.
Compile it all in a stable LFS environment version 7.9 and that all
checks pass without errors.
The strange thing is that the libvirtd process starts without errors
but has arrived at the qemu process launch to understand the system's
capabilities freezes until the following process is killed
/usr/bin/qemu-system-x86_64 -S -none-user-config -nodefaults
-nographic -machine none, accel = kvm: tcg -qmp unix:
/var/lib/libvirt/qemu/capabilities.monitor.sock,server,nowait-pidfile/var/lib/libvirt/qemu/capabilities.Pidfile
-daemonize, since that time libvirtd resumes running and can be used
with virsh.
Performing qemu independently of libvirt works regularly, creates and
runs virtual machines smoothly.

Thanks in advance
