Re: [Xen-fr] procedure d'installation d'une machine virtuelle

[tarek <moktari@xxxxxxxx>]

bonjour a tous,  

   voila j'ai un probleme avec xen..
   J'ai suivi a la lettre les instructions de la
documentation pour l'install, mais je n'arrive
toujours pas a demmarer de machine virtuelle..

je m'explique:

  1) j'ai installer une fedora 4 et xen dessus...
  2) ensuite j'ai créer une image que j'ai compresser

 dd if=/dev/zero of=fedora.img bs=1k seek=2048k
count=1

  3) gzip fedora.img
      --> fedora.img.gz

  4) mke2fs -F -j fedora.img.gz

  5) mount -o loop fedora.img.gz /mnt

6)cp -ax /{root,dev,etc,var,usr,bin,sbin,boot,lib}
/mnt

7) mkdir /mnt/{proc,sys,home,tmp}

8) umount /mnt

xm create -c rawhide (rawhide qui est mon fichier dans
lequel j'ai configuer disk etc...)

et voici les message d'erreur au demarrage:

xm create -c rawhide

# xm create -c rawhide

Using config file "/etc/xen/rawhide".
