Please share logs from nova-compute as well

The error means that Nova found a compute node to run the instance, but it could not start it. You find more information in the nova-compute log, as Deepa says, but possibly also the nova-scheduler log.

Here is nova-compute log : 

2019-02-06 15:48:24.427 16218 INFO nova.compute.resource_tracker [req-9c0c44d8-2f4b-4914-9bd4-57c8ffd682b3 - - - - -] Final resource view: name=compute phys_ram=23981MB used_ram=512MB phys_disk=457GB used_disk=0GB total_vcpus=8 used_vcpus=0 pci_stats=[]

And there is no log on nova-scheduler, but i see this on nova-conductor.log :

Build of instance 42ad9bb0-8975-43a2-86d9-6101c0988925 was re-scheduled: invalid argument: could not find capabilities for domaintype=kvm \n']

I can't believe that you have no nova-scheduler log at all, and that your other logs only contain one message each.

In any case, this is obviously a misconfiguration. Have a look at nova.conf on the compute node(s): In the [libvirt] section, you will find a setting named virt_type. Correct it to be kvm instead of kvm \n.
