Could u attach the nova-compute log file? you can find it in /var/lib/docker/volumes/kolla_logs/_data/nova/nova-compute.log

i was not able to launch instance because i was doing in virtualbox so , that is not supporting hardware acceleration.
so, i added virt_type=qemu in nova.conf file and it working.

i will add patch that will check hardware acceleration support, if not support then it will add entry virt_type=qemu in nova.conf

It's not really Kolla bug, but can be treat as prechecks problem.

Reason: it is not much helpful for now.

 egrep -c '(vmx|svm)' /proc/cpuinfo
If this command returns a value of zero, your compute node does not support hardware acceleration and you must configure libvirt to use QEMU instead of KVM.

For this, change the virt_type option in the [libvirt] section of nova config file

[libvirt]
virt_type=qemu

[Jeffrey Zhang (jeffrey4l)]

pre-check will stop the user to use virt_type=qemu, and he will get some error.

some doc warning may help.
