opnsense 20.7 doesn't boot after installation

[volnei]

Hi,
I'am trying to install a VM on the Centos8 KVM, since the creation of the VM occurs without any problems and the opnsense installs normally and the operation seems to be normal. But when I reboot it doesn't boot anymore.
I have no idea what may be happening, since no other VM has had this type of behavior.

If you need more details please ask me.

Thanks a lot.

I also tested it on another machine, Centos7 with an I3 530 and 16GB RAM, also without success. The problem occurs in the same way.
I also tried to create the VM with UEFI boot, which also does not start after installation.
