Do you understand why my engine vm remains in "Booting from Hard Disk" screen from these logs?

Thanks,

One of possible causes of my engine unable to boot up could be this?

In 4.1.2 I was already in 7.3 and with the same qemu-kvm-ev and libvirt versions of 4.1.3, if I compare the command line of the VM, it was:

diff 4.1.2 4.1.3

So it seems it changed both "machine" (from pc-i440fx-rhel7.2.0 to pc-i440fx-rhel7.3.0) and "cpu" (from qemu64,-svm to Broadwell,+rtm,+hle)
Can I revert so that I can check if it has any influence?

BTW: this is a nested environment, where the L0 host is ESX 6.0 U2.

Thanks for any suggestin to fix engine start

Gianluca

Currently I have set the environment in global maintenance.
Does it make sense to try to start the HostedEngine with an alternate vm.conf to crosscheck it it is then able to start ok?
I see that there is the file /var/run/ovirt-hosted-engine-ha/vm.conf that seems refreshed every minute

It seems that apparently I can copy it into another place, modify it and try to start engine with the modified file using

hosted-engine --vm-start --vm-conf=/alternate/path_vm.conf

is it correct? 

the modified file would be such that:

[root@ovirt02 images]# diff /var/run/ovirt-hosted-engine-ha/vm.conf /root/alternate_vm.conf
