Hello, What config switches need to be passed to the UML kernel if I want it to bo= ot directly from a partition on the host (e.g. /dev/hda3)=3F I tried variou= s combinations (i.e. linux root=3D/dev/hda3.... etc.) but it's not working,= probably I'm missing something. I want to use partitions directly from the host because I think the perform= ance would be better this way - but please correct me if I'm wrong. Best regards, Sebastian |

hi! never tried this and don`t know if that really works(i think it should ), but at least you made an error: you specified the raw partition with the "root=" param. this is wrong, because that param specifies the root-device being used INSIDE the uml. you need to map the phyisical device on the HOST (/dev/hda,b,c) to a device inside the UML (/dev/ubd/x) i would give something like "..... root=/dev/ubd/0 ubd0=/dev/hda3 ...." a try. regards roland ----- Original Message ----- From: "Sebastian Paul Avarvarei" <pr...@pr...> To: <use...@li...> Sent: Saturday, March 27, 2004 12:47 PM Subject: [uml-user] Making UML use partitions from host Hello, What config switches need to be passed to the UML kernel if I want it to boot directly from a partition on the host (e.g. /dev/hda3)?

If you want devfs then it should be: ubd0=/dev/hdb2 root=/dev/ubd/0 [ Of course, instead of hdb2 you should use your partition, but you know that. ] That works. I boot gnoppix from /dev/hdb2 under UML. |
