[Ovirt-devel] How I installed ovirt on fc 12

Mon Feb 1 09:22:29 UTC 2010

Hello,

There has been some changes since my first ovirt installation feedback.
 - ipa-server has been patched (1.2.2-3.fc12)
 - Cobbler does not work out of the box.
 - ovirt-node-image-pxe does not boot (problem with dracut)

Cobbler problem :

The default tpftp config does not work, the problem might be there :

ovirt/server/installer/modules/ovirt/files/cobbler-import (l 47)

cobbler distro add --name="oVirt-Node-$node_arch" --arch=$node_arch \
    --initrd=$node_dir/tftpboot/initrd0.img --kernel=$node_dir/tftpboot/vmlinuz0 \
    --kopts="rootflags=loop root=/ovirt-node-image.iso rootfstype=iso9660 ro console=tty0 console=ttyS0,115200n8"

I think this is the line that adds the ovirt-node pxe config of /var/lib/tftpboot/pxelinux.cfg/default.

To have my node booting, I am using this config in /var/lib/tftpboot/pxelinux.cfg/default :

LABEL oVirt-Node-x86_64
        kernel /images/oVirt-Node-x86_64/vmlinuz0
        MENU LABEL oVirt-Node-x86_64
        append initrd=/images/oVirt-Node-x86_64/initrd0.img ksdevice=bootif lang=  ro rootflags=loop text selinux=0 rootfstype=iso9660 root=live:/ovirt-node-image.iso kssendmac  ks=http://10.75.196.100/cblr/svc/op/ks/profile/oVirt-Node-
x86_64 rd_NO_PLYMOUTH rd_NO_LVM rd_NO_LUKS
        ipappend 2

And I don't understand why there are these lines with MAC in ovirt/server/installer/modules/ovirt/files/cobbler-import

cobbler profile add --name=oVirt-Node-$node_arch --distro=oVirt-Node-$node_arch
cobbler system add --netboot-enabled=1 --profile=oVirt-Node-$node_arch \
    --name=node3 --mac=00:16:3e:12:34:57
cobbler system add --netboot-enabled=1 --profile=oVirt-Node-$node_arch \
    --name=node4 --mac=00:16:3e:12:34:58 --kopts="ovirt_init=scsi ovirt_local_boot"
cobbler system add --netboot-enabled=1 --profile=oVirt-Node-$node_arch \
    --name=node5 --mac=00:16:3e:12:34:59 --kopts="ovirt_init=scsi"

But that's not all. The pxe node image does not boot, there is a bug in dracut : https://bugzilla.redhat.com/show_bug.cgi?id=548283
So I rebuild the pxe image with the patched dracut (on a fc13), and this pxe node image is working on my ovirt server (fc12)

I draw your attention to this tftp option : root=live:/ovirt-node-image.iso
"live:/" is mandatory for dracut, otherwise it can not mount /

I still have problems, I have to disable plymouth and usb (in the server bios) to make the node booting but it's not critical.

Regards ,

A.
