You checked the virtualization in the BIOS, really all the virtualization parameters? Check again the BIOS requirements documentation (IOMMU, VT-x, …, yes all).
Seems to be an unsupported CPU.
HP builds ZBooks with CPUs with VT-x (virtualization support) but without VT-d also.
Please post your CPU identifier.
I have changed the CPU from my ZBook from I7 4700MQ (without VT-d) to i7-4800MQ (with VT-d) for that reason also.
Thanks everyone. After revisiting the bios, i noticed no V Td to be found. The cpu is i7 4710MQ. So it seems that Im at a dead end on this box without a cpu upgrade.
The 4800 cpu is on Amazon (used) for $190.
Perhaps I could recoup some $ on the sale of my used 4710. Not looked into that yet.
What to do… what to do.
Penny for your thoughts?
Thanks again for everyones guidance.

(People, funny things were happening in this thread because @missing_email_user was mentioned. – some replies were getting repeated. It should have been fixed now.)
Yes, because for my ZBook exists a list with possible CPU options. I have used an CPU, that is listed in the docu as option for my ZBook. So Bios recognizes the new CPU without any problem and switches also the VT-d feature to enabled.
After the CPU upgrade, i was able to install and use Qubes (i use it currently). The only problem (but that is not connected to the CPU upgrade) is/was, that i cannot use EFI, i must use legacy bios.
That seems to be a problem with the rather basic support in XEN, if qubes switch to grub + efi, i expect the succesfull usage of efi on my zbook.
