It looks for /dev/loop[n] where losetup prints /dev/loop/[n]. domi thinks the device is not use and tries to set it up but gets an error. A small patch which follows appears to fix the situation.

Thanks. marduk@gentoo.org 2006-05-03 08:34:31 0000 I'm in the infra group. I'm not an ebuild maintainer and, honestly, I don't really have the time right now to be one. Mark@JumpingBean.co.za 2006-05-11 12:06:09 0000 Hi all, I am looking for help on runnung domi to install a fedora domainU. I have the following in my domi.conf #!/bin/bash #This script is generated by http://bugs.gentoo.org/show_bug.cgi?id=112407 and the domi.man file #domi - xen domain installer /etc/domi.conf #domi is a shell script which sets up virtual machines. It creates #virtual disks using either LVM or image files and installs a linux #distribution on the newly created disk. # #domi reads the configuration from /etc/domi.conf and the config file #passed on the command line. Then goes ahead and sets up the virtual #disk without asking further questions, so be careful. #The config files are simply sourced. Thus the syntax for setting the #config options is the usual shell variable style, i.e. VAR="value", #hashmark works for comments and so on. ############################################ #DOMI_NAME="myexample" # Required DOMI_NAME="fedora" ##Name of the virtual machine. #Distribution to install.

And in a /home/mark/domi.conf FEDORA_REPO=http://download.fedora.redhat.com/pub/fedora/linux/core/5/i386/os FEDORA_GROUP=base When I run domi /home/mark/domi.conf I just get ### ### fedora: initialization (i386) ### ### ### fedora: setup disk (lvm volume /dev/volgroup01 /fedora) ### Logical volume "fedora" already exists in volume group "volgroup01" ### ### fedora: cleanup: virtual disk ### ### ### fedora: cleanup: remove tmp files It completes in about 3 seconds. From what I understand domi should download the the fedora packages and create a domU. What am I missing? Mark@JumpingBean.co.za 2006-05-11 13:45:18 0000 found one problem. I had a space in the volumegroup variable name. i.e "/dev/volgroup01 ". This called the script to fail. I now get as far as the following. ### fedora: setup disk (lvm volume /dev/volgroup01/fedora) ### Logical volume "fedora" successfully removed Logical volume "fedora" created Disk geometry for /dev/mapper/volgroup01-fedora: 0kB - 4295MB Disk label type: msdos Number Start End Size Type File system Flags 1 1kB 4026MB 4026MB primary boot 2 4026MB 4294MB 268MB primary add map volgroup01-fedora-part1 : 0 7863281 linear /dev/mapper/volgroup01-fedora 1 add map volgroup01-fedora-part2 : 0 523437 linear /dev/mapper/volgroup01-fedora 7863282 ### ### fedora: setup root fs and swap ### Setting up swapspace version 1, size = 267993 kB LABEL=fedora-swap, UUID=8975dae0-7cd6-4fb8-8030-8b8d745f0bb1 ### ### fedora: copy saved yum cache [/var/cache/domi/fedora-pub-fedora-linux-core-5-i386-os] ### which: no yum in (/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/opt/bin:/usr/i686-pc-linux-gnu/gcc-bin/3.4.5:/opt/sun-jdk-1.5.0.06/bin:/opt/sun-jdk-1.5.0.06/jre/bin:/usr/qt/3/bin:/usr/kde/3.4/sbin:/usr/kde/3.4/bin) error: yum not found ### ### fedora: save yum cache [/var/cache/domi/fedora-pub-fedora-linux-core-5-i386-os] ### ### ### fedora: cleanup: virtual disk ### /dev/mapper/volgroup01-fedora-part1 umounted del devmap : volgroup01-fedora-part1 del devmap : volgroup01-fedora-part2 ### ### fedora: cleanup: remove tmp files ### Do I need to download these files manually or should the script do it for me? Mark@JumpingBean.co.za 2006-05-11 13:51:41 0000 ok --- looks like it need yum installed but I cant find it in the ebuilds :( chrb@gentoo.org 2006-05-19 05:08:43 0000 marduk - I've applied the patch as a sed line in the ebuild. Mark - looks like it needs yum - please open another bug (building suse may also require kpartx and y2pmsh). I haven't got time to write ebuilds for those, so if you do please attach them to the new bug report. Thanks.
