 I have noticed that sometimes virsh shows the real error (like firewalld being 
stopped).Can you try to start paused and then ask virsh to resume:hosted-engine 
--vm-start-paused
virsh -c qemu:///system?authfile=/etc/ovirt-hosted-engine/virsh_auth.conf list

virsh -c qemu:///system?authfile=/etc/ovirt-hosted-engine/virsh_auth.conf 
resume HostedEngine

Ok, so maybe you configured your hosted-engine VM for spice only.

In that case you can:

directly check spice port:
virsh -r dumpxml HostedEngine |grep -i tlsPort

Copy ca cert (/etc/pki/vdsm/libvirt-spice/ca-cert.pem) to your laptop.
Identify the subject of /etc/pki/vdsm/libvirt-spice/server-cert.pem with:
openssl x509 -in /etc/pki/vdsm/libvirt-spice/server-cert.pem -noout -subject

Add a console password with
hosted-engine --add-console-password

Connect over spice with something like:
remote-viewer --debug --spice-ca-file="/tmp/ca-cert.pem"
--spice-host-subject="O=example.com, CN=host1.example.com"  spice://
host1.example.com?tls-port=5900

Yes. Sorry I forgot to copy that part. It didn't respond with a connection

check if that VM is really up with
  virsh -r list

If so maybe it could be something with fsck previnting it from booting due
to disk errors; you can try to connect with VNC since in that case neither
ssh or the serial console will work due to the lack of guest OS support.
You can use
  hosted-engine --add-console-password
to add a temporary VNC password; it will also print out the connection
string.
