Leandro,
I do agree with Tim that you should check your VHD is correct. Try to
import it using single instance XenServer and see if it can boot the VM.
Cloudstack, when you do export-import, mostly works with templates. And you may
need to create new VM from the template you have registered.
Regards,
Vadim.

Subject: Re: XenServer (VM_HVM_REQUIRED) - RAW image converted to VHD
CentOS 7 needs to be HVM for XenServer. If you created the VM on XenServer
6.5, then when you register it with CloudStack you'll want to set the
"requireshvm" flag when you import. With CentOS 6, assuming you built it from
the CentOS 6 template, it could be PV or HVM. I've installed directly from ISO
in 6.5 both CentOS 6 and 7 with no need to modify the kernel.
This is all background information which might guide you a solution.
Looking at your specific comments; since you're starting with a RAW image, and
following that blog post, you're probably starting with an HVM image (which
also explains why things work on KVM). What I'd do is bypass CloudStack
(remove a moving part) and try and import that VHD directly into XenServer and
see what happens. Once it comes in, in the CLI issue a 'xe vm-list params=all
uuid=yyyy' where yyyy is the uuid of your freshly imported VM. Look at the
various _boot_ params and see if HVM or PV options are set. If HVM_boot_order
is set, then you need HVM. Of course, if it doesn't import properly, or can't
start, that'll be the first thing to test.
This will confirm both that your VHD is legit, but also if the CloudStack HVM
message is also legit. If it's legit, you're next challenge will be to
determine why CloudStack thinks you don't have it. To solve that you'll need
to provide more details on how XenServer was installed, and the version of
CloudStack.
