| I'm afraid not. HVM is specifically a set of hardware extensions to x86 to permit it to be virtualized more easily. Cross-architecture binaries are out of scope for this feature, and Xen definitely doesn't support it. You could get a slow emulation by using Qemu, but it would be very slow indeed.
If the image you're using is open-source, you could try building it under ARM by using the relevant packages. I'm not familiar enough with it to know if this is practical or not, but you could try the xen-users or the project-specific mailing list.
-anil I thought that with this hvm allow me to emulate another architecture, but if this feature did not work on arm, I do not know how. you know a program, allowing me to do that? without losing too much power compared to the host machine.

It looks like you are trying to install an x86_64 virtual machine image onto an ARM Xen host. This will not work...

This mode doesn't exist on ARM: it's an option to run x86 guests in hardware virtualisation mode. Are you trying to boot an x86 guest on ARM?

Why are you trying to create an HVM guest on Xen/ARM? You should just be using the default PV mode on ARM to launch guests.
