Note
As of Release 3.4.6, support for PVM guests is removed. For information information, see Section 8.1, “Removed Features in 3.4.6”.
If you change the domain type of a virtual machine based on CentOS 5 from PVM to PVHVM, and then attempt to start the virtual machine, it does not boot successfully. The following error displays in the virtual machine console:
Error 13: Invalid or unsupported executable format
Workaround: There is no workaround for this issue.
