== Project Name ==
Web-based Virtual Machine Management(aka virtbuilder)
== Project Description ==
== Project Leader(s) ==
[[User:Jb|Jesse Buchanan]]
== Project Contributor(s) Details ==
== Unresolved issues == * Design issue: Expiry of virtual machines (how long should they last? when should they be cleaned up?)* Design issue: Validating RAM/disk space usage (how to stop users from bringing server to a grinding halt?)* Known bug: Cannot boot more than one virtual machine because VNC port is in use - must modify this. == Related bugs == Since I'm not hacking on Firefox or any Mozilla products per se, finding bugs related to my project is sort of difficult. To get in the right direction I tried searching Bugzilla for 'vmware', 'xen', 'kvm', and 'try server'. Here are a few results: * [https://bugzilla.mozilla.org/show_bug.cgi?id=386091 Moz386091 Firefox Profiles in VMware Host create multiple files]* [https://bugzilla.mozilla.org/show_bug.cgi?id=393092 Moz393092 tracking bug for next try server version]* [https://bugzilla.mozilla.org/show_bug.cgi?id=393259 Moz393259 Try server slaves should not use anonymous pserver on cvs.mozilla.org for checking out] Update: As of October 21 2007 I've noticed that I'm going to be using the Redhat bugzilla a lot more than Mozilla's. Here are a few actually relevant bugs: * [https://bugzilla.redhat.com/show_bug.cgi?id=248010 RH248010 cannot create vm on qemu-based setup]* [https://bugzilla.redhat.com/show_bug.cgi?id=253354 RH253354 Virt-Manager does not allow changing RAM allocation for KVM guest]* [https://bugzilla.redhat.com/show_bug.cgi?id=246354 RH246354 2 pointer cursors diverging under -vnc option] Update: On November 17 2007 I filed a bug against virt-manager in Fedora 8. I am unable to create guests in virt-manager from CDROM installation media (must use a .iso file). * [https://bugzilla.redhat.com/show_bug.cgi?id=389101 RH389101 virt-manager fails to create KVM guests from CD-ROM installation media] == Goals ===== v0.1 goal === * very simple CLI tool that will boot a pre-built Xen machine, using either libvirt or virsh* if time, very rudimentary control of virtual machine (i.e. change RAM)* [added in lieu of above] HTML mockup === v0.2 === * something to make modifications to XML* shell out to make LVM volumes === v0.3 === * web-based front end to v0.2 == Releases == === Current: v0.3 release === ==== Description ==== * Pylons web application* Handles simple actions such as create, destroy, and list VMs ==== Download ==== * [http://matrix.senecac.on.ca/~jabuchan/virtbuilder0.3.zip Download virtbuilder0.3.zip] ==== Requirements ==== Environment:* Recent Linux distribution (Fedora 8 was my testing platform, YMMV)* An LVM volume group with a bit of free space.* An Intel-VT compliant CPU (hardware assisted virtualization), for KVM.* A preinstalled virtual machine to be cloned, installed to an LVM volume. Python:* libvirt python bindings* BeautifulSoup* Pylons ==== Installation and usage ==== * Download and untar.* Edit development.ini:** virtbuilder.lvm.vg: Provide the name of your LVM volume group.** virtbuilder.vmtemplates: Provide the directory your template XMLs are stored in. (optional, default will work)* Change permissions on libvirt, and set LVM as suid, so Pylons doesn't need privileged access:** chmod +s /usr/sbin/lvm** chmod -R 777 /var/run/libvirt** Run the Pylons project from the top-level virtbuilder dir:** paster serve development.ini* We're done. Go to http://127.0.0.1:5000 and start making VMs. === Obsolete releases === ==== v0.1 release (OBSOLETE) ==== * Python script which boots a prebuilt KVM virtual machine via libvirt* Barebones mockup of web interface: the project in a nutshell* [http://matrix.senecac.on.ca/~jabuchan/virtbuilder0.1.zip Download virtbuilder0.1.zip] ==== v0.25 release (OBSOLETE) ==== * Python script which:** reads a virt-image(5) XML file,** creates an LVM snapshot of the target /dev/hda,** boots the newly created VM instance via libvirt.* [http://matrix.senecac.on.ca/~jabuchan/virtbuilder/README Download README]* [http://matrix.senecac.on.ca/~jabuchan/virtbuilder/CHANGELOG Download CHANGELOG]* [http://matrix.senecac.on.ca/~jabuchan/virtbuilder0.25-r07.zip Download virtbuilder0.25-r07.zip]
