I noticed the koan parameter --virt-path and tried creating a vhost
with following command:
koan --server <some-ip> --virt --profile CentOS5-xen-i386 -P VolGroup00
The profile and kickstart files are generated by an import from the CentOs5 DVD.
This command creates 1 lv. The domU uses this as a disk (xvda) and
creates partitions on this.
It is working, but not really the thing i want.
I want that koan will create multiple lv's on the dom0. Each lv on
dom0 is a partition on domU. This means that the lv is directly
formatted in the dom0, and you can mount that logical volume like a
normal lv (it IS a normal volume) in the dom0.
Is this (allready) possible with koan (or virt-inst)?
I believe you are stuck with the extra level of indirection -- that is
that partitions in your host (dom0) appear
as disks in your domU -- with both tools. I don't think you can feed a
partition up without a corresponding virtual disk :)
(Note that you don't have to use LVM for this -- regular partitions work
too)

Hi All,
In March this year Fred posted a request on this mailinglist:
http://www.redhat.com/archives/et-mgmt-tools/2007-March/msg00119.html
Implemented.
See the documentation for --virt-path in the koan manpage.
What is the status of this request, is it working in the latest version of koan?
I noticed that it is now possible to use a logical volume as a disk,
but it is also possible to use logical volumes on dom0 as partitions
on domU?
There are three ways storage can be specified:
-- basic disk images on the filesystem (default behavior)
-- specifying a logical volume group that has free space in it, where
then koan will carve a paritition out of it named after the virtual machine
This allows for using a common LVM group for all your virtual machines,
which is rather useful.
-- specifying a specific partition for koan to use as storage.
I hope that answers the question!
Recently a few folks have been asking for ways to specify multiple
"disks" for their configurations ... and that's something I am going to
be looking at.
Thanks for the information,
Johan Huysmans
