Проблемы, запускающиеся libvirt демон в Ubunti 18.04

Я пытаюсь работать virt-manager соединяться с Xen. Однако не возможный запустить libvirt демона.

При запуске/usr/sbn/libvirtd через systemctl start libvirtd или путем запуска /usr/sbin/libvirtd через cmdline я получаю ошибку:

libvirtd[4289]: libvirtd: libxl_fork.c:353: sigchld_installhandler_core: \
Assertion `((void)"application must negotiate with libxl about SIGCHLD", \
!(sigchld_saved_action.sa_flags & SA_SIGINFO) && \ 
(sigchld_saved_action.sa_handler == SIG_DFL || \ 
sigchld_saved_action.sa_handler == SIG_IGN))' failed.

Какая-либо подсказка, что могло быть неправильным?

Я выполняю Xen, установленный через apt-get install xen-hypervisor-4.9-amd64.

Distributor ID: Ubuntu
Description:    Ubuntu 18.04.1 LTS
Release:    18.04
Codename:   bionic

/usr/sbin/libvirtd прибывает из:

$dpkg -l | grep libvirt-daemon
