Kimchi Project

Kimchi is an HTML5 based management tool for KVM. It is designed to make it as easy as possible to get started with KVM and create your first guest.

Kimchi runs as a Wok plugin. Wok runs as a daemon on the hypervisor host.

Kimchi manages KVM guests through libvirt. The management interface is accessed over the web using a browser that supports HTML5.

Browser Support

Wok and its plugin can run in any web browser that supports HTML5. The Kimchi community (responsible for Wok project) makes an effort to test it with the latest versions of Chrome and Firefox browsers, but the following list can be used as reference to browser support.

Desktop Browser Support:

  • Internet Explorer: Current version
  • Chrome: Current version
  • Firefox: Current version
  • Safari: Current version
  • Opera: Current version

Mobile Browser Support:

  • Safari iOS: Current version
  • Android Browser Current version

Hypervisor Distro Support

Kimchi might run on any GNU/Linux distribution that meets the conditions described on the 'Getting Started' section below.

The Kimchi community makes an effort to test it with the latest versions of Fedora, RHEL, OpenSuSe, and Ubuntu.

Getting Started

Install Dependencies

For fedora and RHEL:

 $ sudo yum install wok libvirt-python libvirt \
                    libvirt-daemon-config-network python-imaging \
                    qemu-kvm python-ethtool sos python-ipaddr \
                    nfs-utils iscsi-initiator-utils pyparted \
                    python-libguestfs libguestfs-tools \
                    python-websockify novnc spice-html5 \
                    python-configobj python-magic python-paramiko

 # If using RHEL, install the following additional packages:
 $ sudo yum install python-unittest2 python-ordereddict

 # Restart libvirt to allow configuration changes to take effect
 $ sudo service libvirtd restart

# These dependencies are only required if you want to run the tests:
$ sudo yum install pyflakes python-pep8 python-requests python-mock

Note for RHEL users: Some of the above packages are located in the Red Hat EPEL repositories. See this FAQ for more information on how to configure your system to access this repository.

And for RHEL7 systems, you also need to subscribe to the "RHEL Server Optional" channel at RHN Classic or Red Hat Satellite.

For Ubuntu (Debian-based):

$ sudo apt-get install wok python-imaging python-configobj websockify \
                       novnc python-libvirt libvirt-bin nfs-common \
                       qemu-kvm python-parted python-ethtool sosreport \
                       xsltproc python-ipaddr python-lxml open-iscsi \
                       python-guestfs libguestfs-tools spice-html5 \
                       python-magic python-paramiko \

# These dependencies are only required if you want to run the tests:
$ sudo apt-get install pep8 pyflakes python-requests python-mock

For openSUSE:

$ sudo zypper install wok libvirt-python libvirt \
                      libvirt-daemon-config-network python-imaging \
                      kvm python-ethtool python-ipaddr nfs-client \
                      open-iscsi python-parted python-libguestfs \
                      python-configobj guestfs-tools python-websockify \
                      novnc python-magic

# These dependencies are only required if you want to run the tests:
$ sudo zypper install python-pyflakes python-pep8 python-requests python-mock

Note for openSUSE users: Some of the above packages are located in different openSUSE repositories. See this FAQ for python-parted, this FAQ for python-ethtool, and this FAQ for python-magic to get the correct repository based on your openSUSE version. And this FAQ for more information on how configure your system to access this repository.

Build and Install

Wok:
$ ./autogen.sh --system

$ make
$ sudo make install   # Optional if running from the source tree


Kimchi:
$ cd plugins/kimchi

For openSUSE 13.1:
$ ./autogen.sh --with-spice-html5

Otherwise:
$ ./autogen.sh --system

$ make
$ sudo make install   # Optional if running from the source tree

Run

$ sudo wokd --host=0.0.0.0

If you cannot access Wok, take a look at these 2 points:

  1. Firewall Wok uses by default the ports 8000, 8001 and 64667. To allow incoming connections:

    For system using firewalld, do: sudo firewall-cmd --add-port=8000/tcp --permanent sudo firewall-cmd --add-port=8001/tcp --permanent sudo firewall-cmd --add-port=64667/tcp --permanent sudo firewall-cmd --reload

    For openSUSE systems, do: sudo /sbin/SuSEfirewall2 open EXT TCP 8000 sudo /sbin/SuSEfirewall2 open EXT TCP 8001 sudo /sbin/SuSEfirewall2 open EXT TCP 64667

    For system using iptables, do: sudo iptables -A INPUT -p tcp --dport 8000 -j ACCEPT sudo iptables -A INPUT -p tcp --dport 8001 -j ACCEPT sudo iptables -A INPUT -p tcp --dport 64667 -j ACCEPT

    Don't forget to correctly save the rules.

  2. SELinux Allow httpd_t context for Wok web server:

    semanage permissive -a httpd_t

Test

$ cd plugins/kimchi
$ make check-local # check for i18n and formatting errors
$ sudo make check

After all tests are executed, a summary will be displayed containing any errors/failures which might have occurred.

Usage

Connect your browser to https://localhost:8001. You should see a screen like:

Wok Login Screen

Wok uses PAM to authenticate users so you can log in with the same username and password that you would use to log in to the machine itself. Once logged in you will see a screen like:

Kimchi Guest View

This shows you the list of running guests including a live screenshot of the guest session. You can use the action buttons to shutdown the guests or connect to the display in a new window.

To create a new guest, click on the "+" button in the upper right corner. In Kimchi, all guest creation is done through templates.

You can view or modify templates by clicking on the Templates link in the top navigation bar.

The template screen looks like:

Kimchi Template View

From this view, you can change the parameters of a template or create a new template using the "+" button in the upper right corner.

To create a template, you need an ISO on your host or using remote one. If you are willing to use your own ISO, please copy it to out of box storage pool (default path is: /var/lib/kimchi/isos).

Known Issues

  1. When you are using NFS as storage pool, check the nfs export path permission is configured as: (1) export path need to be squashed as kvm gid and libvirt uid: /my_export_path *(all_squash,anongid=, anonuid=,rw,sync) So that root user can create volume with right user/group. (2) Chown of export path as libvirt user, group as kvm group, In order to make sure all mapped user can get into the mount point.
