Choosing A Webhost:
A web hosting service is a type of Internet hosting service that allows individuals and organizations to provide their own website accessible via the World Wide Web. Web hosts are companies that provide space on a server they own for use by their clients as well as providing Internet connectivity, typically in a data center. Web hosts can also provide data center space and connectivity to the Internet for servers they do not own to be located in their data center, called colocation. more...

treating logical volumes as physical drives: msg#00142

Subject: |
treating logical volumes as physical drives |
I would like to use a logical volume as a "physical" drive on which I
can install a fedora operating system. As of now, when I run xenguest-
installer, it treats the install location that I specified ( which is
an unformatted logical volume that I had just created ) as a physical
drive (named "xvda") and allows me to perform a basic install on it.
When I look at that logical volume, it comes up as a "foreign"
device, because it contains a /boot directory, and a volume group
consisting of a / directory and a swap directory. I was wondering
how to mimic that effect without using my xenguest-installer program,
so that when I pop a CD in and the installer starts up, I can specify
a logical volume and let the installer treat it as a physical drive
just like the xenguest-installer program does.
I am trying to accomplish this because I was unable to install FC4
via the xenguest-installer. I had mounted the image as a loopback
device to /var/ftp/pub and specified the /pub directory in FTP
server's root folder as my "Installation source", and was greeted by
an error from my FTP server (vsftpd) saying "550 Failed to change
directory". When I do the exact same thing except mount the FC6 iso
instead of the FC4 iso, everything works fine. What could I be doing
wrong?
If all else fails, I guess I can just specify in my /etc/xen/xm-
fc4-001 file the kernel and the ramdisk parameters, and install FC4
on an ext3 formatted logical volume specified as the / directory, and
thus reuse my existing /boot directory instead of trying to use the
pygrub bootloader with a new /boot directory. In this case, where
could I find a compiled xenU kernel and an appropriate initrd image
for FC4?
Thank you very much and happy new years to all!
