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
