I have continued to experiment creating VMs and blowing them away using
a variety of storage and other options. I want to be able to create a
Fedora 8 Guest VM, install a number of packages, configure them, and
then save it as a template. Then copy the template and install it. The
file storage options seemed the best, but it apparently has flaws for
speed and integrity. I created one using LVM in the guest, but read
that was unnecessary overhead and made it difficult to mount the
images. So I tried to create one by deleting the volumes and that
seemed to work, but it still created a partition with the file system
inside and I could not mount it. The blktap driver was recommended if
you were not going to use an LVM in the guest or Dom0, but I do not know
how to invoke virt-install to create a simple blktap driver based ext3
file system in a file. What are virt-install parameters do you use to
specify using the blktap driver to a file? And if there are any
misconceptions in my message, please feel free to trounce on them. If
there is a wiki or man page, please just give me the URL. Thank you.

^^ That kind of thing. The man page has a few examples right at the end.

I just installed Fedora 8 and the Fedora Xen packages. I have been
trying to get a variety of VMs installed, but the most basic one is
just a Fedora guest VM. Please correct me if I am wrong, but the
correct tool is "virt-install". It asks a number of questions, but
the last is "What is the install location?" I finally found an
excerpt from a book that had
"http://download.fedora.redhat.com/pub/fedora/linux/core/6/i386"; as
the answer. But that is not correct it is actually:
"http://download.fedora.redhat.com/pub/fedora/linux/core/*6*/i386/os";,
but that is for core 6, not 7 or Fedora 8. And the file tree does
not have a
"http://download.fedora.redhat.com/pub/fedora/linux/core/*8*/i386/os";.
Is there no place where fc8's files are posted? Or are we supposed
to specify 6? I would have said okay, except I started getting
messages like this:
Fedora Core & Extras mered during the F7 release, so the download URLs
changed style slightly
eg, i386 F8
http://download.fedora.redhat.com/pub/fedora/linux/releases/8/Fedora/i386/os/
eg, x86_64 F7
http://download.fedora.redhat.com/pub/fedora/linux/releases/7/Fedora/x86_64/os/
Basically, you always want the URL ending in '/os/' for your release.
You can also use nfs:// or ftp:// URLs.

Dan.
