can't create XEN VM's in CloudMin 5.3 - "Error: HVM guest support is unavailable"

I see that I suddently can’t create XEN VM’s on some of my XEN servers, without Intel VT support, anymore since I upgraded to CloudMin 5.5.

Is there a way to configure CloudMin 5.5 not to try and use HVM on hardware that doesn’t support Intel VT??

This is the error I get:

Starting up usa-shinga ..
.. failed : Error: HVM guest support is unavailable: is VT/AMD-V supported by your CPU and enabled in your BIOS? Using config file "/xen/usa-shinga.cfg". 

I have the same error, how can we start the vm using the paravirtualization mode ? shall we change the option builder = ‘hvm’ to ‘linux’ ?

when i change this option to linux i get an other error message: … failed : Error: (2, ‘Invalid kernel’, “elf_xen_note_check: ERROR: Not a Xen-ELF image: No ELF notes or ‘__xen_guest’ section found.\n”) Using config file “/xen/xen-ubuntu1010.cfg”.
