Bonjour 
 
J'essaye en ce moment de me "monter" un petit UML pour faire des expériences. 
J'ai chopé un noyau 2.6.10, configuré et compilé peinard (deux trois warnings mais ça a compilé). 
J'ai pris sur [http://user-mode-linux.sourceforge.net/(...)](http://user-mode-linux.sourceforge.net/) un rootfs (Debian 3.0r0.ext2) 
Mais mon noyau veut pas ! 
Je le lance en faisant ./linux par exemple, et vla ti pas qu'il ne panique pas alors qu'il a pas de rootfs ! c'est complètement l'inverse de ce qui est décrit sur internet 
Ensuite j'essaye des combinaisons d'arguments, ça marche pas : 
./linux udb0=Debian-3.0r0.ext2 nosysemu mem=64M 
./linux rootfs=Debian-3.0r0.ext2 nosysemu mem=64M 
Et plein d'autre... 
À chaque fois, j'ai rien de "bien" : 
 suse@linux:~/OSs/UML> ./linux udb0=Debian-3.0r0.ext2 nosysemu mem=64M 
 Checking for the skas3 patch in the host...found 
 Checking for /proc/mm...found 
 Checking PROT_EXEC mmap in /tmp...OK 
 Linux version 2.6.10 (suse@linux) (gcc version 3.3.4 (pre 3.3.5 20040809)) #3 Fri Feb 4 17:48:38 CET 2005 
 Built 1 zonelists

 Checking for host processor cmov support...Yes 
 Checking for host processor xmm support...No 
 Checking that ptrace can change system call numbers...OK 
 Checking syscall emulation patch for ptrace...missing 
 Checking that host ptys support output SIGIO...Yes 
 Checking that host ptys support SIGIO on close...No, enabling workaround 
 Checking for /dev/anon on the host...Not available (open failed with errno 2)

Et ça retourne à la console, comme si de rien n'était ! 
 
Que faire pour pouvoir l'utiliser ? 
Merci d'avance...
