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
