virt-install

[Frederick N. Brier]

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:

    4gb seg fixup, process beagle-build-in (pid 1793), cs:ip 73:0811cbff
    printk: 5990213 messages suppressed.

So there seems to be a problem.  I found this message thread saying 
there is a problem usiing the fc6 install location.

    http://lists.xensource.com/archives/html/xen-users/2006-11/msg00034.html

If anyone knows where the fc8 location is please respond!  Thank you.

No. Core and Extras repositories have been merged with the release of 
Fedora 7 and the location has changed to "Releases. An example mirror 
would be

You can also use virt-manager

If F8 will suffice, whatever you already installed from is fine.

btw You need to tell use whether you're using hardware virtualisation 
(hvm) or paravirtualisation. The answers are different.

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...

eg, x86_64 F7

http://download.fedora.redhat.com/pub/fedora/linux/releases/7/Fedora/x86_...

Basically, you always want the URL ending in '/os/' for your release.

You can also use  nfs:// or ftp:// URLs.

Dan.

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

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.
