Getting 'No valid host was found' when lauching an instance on DevStack. DevStack branch is stable/kilo running on Ubuntu-Desktop VM.

Instance is cirros over small flavour (but also fails with any other).

Can anyone shed a light on what is happening? Info below:

kvm-qemu: QEMU emulator version 2.0.0 (Debian 2.0.0+dfsg-2ubuntu1.19)
libvirt: libvirtd (libvirt) 1.2.2

$ egrep -c '(vmx|svm)' /proc/cpuinfo
16

$ grep -r virt_type /etc/nova/nova.conf
virt_type = qemu
libvirt_type = qemu
