36.7. Wrong kernel image error - non-PAE kernel on a PAE platform
If you to boot a non-PAE kernel, para-virtualized guest the error message below will display. It indicates you are trying to run a guest kernel on your Hypervisor which at this time is not supported. The Xen hypervisor presently only supports PAE and 64 bit para-virtualized guest kernels.

The rules for hypervisor compatibility are:
- para-virtualized guests must match the architecture type of your hypervisor. To run a 32 bit PAE guest you must have a 32 bit PAE hypervisor.
- to run a 64 bit para-virtualized guest your Hypervisor must be a 64 bit version too.
- fully virtualized guests your hypervisor must be 32 bit or 64 bit for 32 bit guests. You can run a 32 bit (PAE and non-PAE) guest on a 32 bit or 64 bit hypervisor.
- to run a 64 bit fully virtualized guest your hypervisor must be 64 bit too.
