Hello, my situation: Distribution: openSuse 10.3 xen 3.1 1x Dom0: kernel 2.6.22.19 2x DomU: kernel 2.6.22.19 Now I want to create a third DomU containing an openSuse 11.2. This distributuon is equipped with a PAE-enabled kernel only, while the existing Dom0 and DomUs use kernel without PAE. This leads to a error xc_dom_compat_check: guest type xen-3.0-x86_32 not supported by xen kernel Because the 11.2 openSuse is not equipped with non-PAE kernel, I''d like to change the existing Dom0 and DomUs to PAE-enabled kernels as well. Changing Dom0 was easy. Of course I get now the xc_dom_compat_check errors when trying to start the existing DomUs. I wonder what the best way is to change the kernel of the DomUs? 2 solutions I am thinking about are: 1. In the config files used for creation of DomUs the loaded kernel is named "vmlinuz-xen" and the initrd "initrd-xen". I could rename filenames of PAE-enabled kernel and initrd to that names in the filesystem of the DomU. 2. I could change the config-files and create new vms. I''m sure there are better ways for the change of a kernel used in the DomUs. Or should I use one of the two above?
