[Xen-devel] Problem creating x86_64 PVH mini-os domain

[Bruno Alvisio <bruno.alvisio@xxxxxxxxx>]

Hi all,

 

I was trying to create mini-os PVH instances both x86_32 and x86_64. I have no issue with x86_32 but when trying to ‘xl create’ x86_64 type I get the following error:

root@debianxen:/home/balvisio# xl -vvv create minios_pvh.cfg

The config file used is:

 

type="pvh"

memory=1024

vcpu=2

name="minios"

kernel="/home/balvisio/mini-os/mini-os"

 

The minios elf file header is:

 

root@debianxen:/home/balvisio/mini-os# readelf -a mini-os

ELF Header:

  Magic:   7f 45 4c 46 02 01 01 00 00 00 00 00 00 00 00 00

  Class:                             ELF64

  Data:                              2's complement, little endian

  Version:                           1 (current)

  OS/ABI:                            UNIX - System V

  ABI Version:                       0

  Type:                              EXEC (Executable file)

  Machine:                           Advanced Micro Devices X86-64

  Version:                           0x1

  Entry point address:               0x0

  Start of program headers:          64 (bytes into file)

  Start of section headers:          2422464 (bytes into file)

  Flags:                             0x0

  Size of this header:               64 (bytes)

  Size of program headers:           56 (bytes)

  Number of program headers:         2

  Size of section headers:           64 (bytes)

  Number of section headers:         22

  Section header string table index: 21

  

Is there any extra setup needed to launch this type of domain?

Just in case, my host system is an x86_64 system.

 

Happy New Year!

 

Cheers,

 

Bruno
