Adds a check to see if cpu is compatible x86-64-vv3

[lstocchi]

Not an error i faced but something i read in a discussion in the tech-list and maybe an opportunity to improve the extension.

RHEL 10 requires CPUs that support the x86-64-v3 microarchitecture.
In the email thread the person was complaining that when trying to create a RHEL 10 VM using Hyper-v it did not work and he did not know why. It came out that he was using an old pc having an old CPU which did not support x86-64-v3 instructions.

I don't know how often such an error can happen and if it makes sense to add a check.
Feel free to close it
