Revision as of 19:35, 1 January 2012
I had problems booting a 32bit Alpine domU on a OracleVM 2.2.2 (64bit) host - most probably since the Alpine kernel uses PVops.
The domU kernel failed to load with the following error:
- Error: (2, 'Invalid kernel', 'elf_xen_note_check: ERROR: Will only load images built for the generic loader or Linux images')
Solution is to make sure you have a 64bit ISO.
Changes:
I had to ln -s /media/cdrom to /media/xvdc or setup-alpine would not find some information.
