Re: [libvirt] Problem with fullyvirtualized guest direct kernel boot

Hi All, I am trying to use fullyvirtualized guest direct kernel boot, but all I see is the following error: libvir: Xen Daemon error : POST operation failed: (xend.err 'Error creating domain: (2, \'Invalid kernel\', "elf_xen_note_check: ERROR: Not a Xen-ELF image: No ELF notes or \'__xen_guest\' section found.\\n")') Kernel, initrd and root file system are extracted from working Fedora 9 disk image without any additional tinkering. Guest Fedora is clean and was installed from scratch. When I use this whole disk image with fullyvirtualized guest BIOS boot with, everything works fine. I also tried paravirtualized guest bootloader with another linux kernel and it also works fine. Xen version is 3.2.1-rc1-pre. Host OS is Ubuntu Hardy.

Here is the libvirt config for direct kernel boot: <domain type='xen' id='18'> <name>test1</name> <uuid>4dea22b31d52d8f32516782e98ab3fa0</uuid> <os> <type>linux</type>
