XenServer (VM_HVM_REQUIRED) - RAW image converted to VHD
Hi guys,
I've created a raw image and installed CentOS 7 (or even 6) into it but
cannot boot it inside XenServer 6.5 after convert it to VHD as described
here (
http://blogs.citrix.com/2012/10/04/convert-a-raw-image-to-xenserver-vhd/).
When starting, i get the error VM_HVM_REQUIRED. The guest kernel has Xen
enabled.
If i convert it to QCOW2, i can boot the same image at my KVM cluster.
Do you guys have any problem like this?
Thanks.

Thanks Guys. I'll try to do the way you said.
I'll report the results here.
Thanks.

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.

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.

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.

I've created the vhd from scratch and registered it through cloudstack API.
Thanks.

Hi, Leanardo
How did you register VHD at XenServer? using import or creating VM from template?

Hi guys,
I've created a raw image and installed CentOS 7 (or even 6) into it but cannot boot it inside XenServer 6.5 after convert it to VHD as described here ( http://blogs.citrix.com/2012/10/04/convert-a-raw-image-to-xenserver-vhd/).
When starting, i get the error VM_HVM_REQUIRED. The guest kernel has Xen enabled.
If i convert it to QCOW2, i can boot the same image at my KVM cluster.
Do you guys have any problem like this?
Thanks.
