Test Day:2012-04-12 libguestfs
In Fedora 17, libguestfs 1.17.x will be available (upgraded from 1.10 in Fedora 15 and 1.16 in Fedora 16).
You will need a Fedora 17 machine. Having at least one guest will be very helpful.
You can test libguestfs inside an F17 virtual machine, but it will run a lot slower. For best performance, run the tests in F17 running on baremetal with VT extensions.
Installing libguestfs and the virt tools
As root, do:
# yum install libguestfs-tools
If you want to write libguestfs scripts or programs, install one of the language bindings, eg:
# yum install libguestfs-devel \ perl-Sys-Guestfs python-libguestfs \ ruby-libguestfs ocaml-libguestfs-devel
Check it's working by running this command (you don't need to be root):
This command will run some simple tests and eventually print out:
===== TEST FINISHED OK =====
If it doesn't print this out, or seems to fail for some other reason, please file a bug including the complete, unedited output.
Now check how fast the appliance gets created:
$ time guestfish -a /dev/null run
Run this a few times so the cache is "hot". As a typical guide, you should see times like:
- 3-6 seconds, on modern hardware with virtualization extensions
