How to update gstfsd daemon on hypervisor:
wget -O - https://bit.ly/2NAaWXG | sudo tee -a /usr/local/bin/gstfsd
sudo service supervisor restart
WebVirtCloud is a virtualization web interface for admins and users. It can delegate Virtual Machine's to users. A noVNC viewer presents a full graphical console to the guest domain. KVM is currently the only hypervisor supported.
Install an OS and run specified commands. Installer supported OSes: Ubuntu 18.04, Debian 10, Centos/OEL/RHEL 8. It can be installed on a virtual machine, physical host or on a KVM host.
wget https://raw.githubusercontent.com/retspen/webvirtcloud/master/install.sh
chmod 744 install.sh
# run with sudo or root user
./install.sh
You should generate SECRET_KEY after cloning repo. Then put it into webvirtcloud/settings.py.
import random, string
haystack = string.ascii_letters + string.digits + string.punctuation
print(''.join([random.SystemRandom().choice(haystack) for _ in range(50)]))
sudo apt-get -y install git virtualenv python3-virtualenv python3-dev python3-lxml libvirt-dev zlib1g-dev libxslt1-dev nginx supervisor libsasl2-modules gcc pkg-config python3-guestfs
git clone https://github.com/retspen/webvirtcloud
cd webvirtcloud
cp webvirtcloud/settings.py.template webvirtcloud/settings.py
# now put secret key to webvirtcloud/settings.py
sudo cp conf/supervisor/webvirtcloud.conf /etc/supervisor/conf.d
sudo cp conf/nginx/webvirtcloud.conf /etc/nginx/conf.d
cd ..
sudo mv webvirtcloud /srv
sudo chown -R www-data:www-data /srv/webvirtcloud
cd /srv/webvirtcloud
virtualenv -p python3 venv
source venv/bin/activate
pip install -r conf/requirements.txt
python3 manage.py migrate
sudo chown -R www-data:www-data /srv/webvirtcloud
sudo rm /etc/nginx/sites-enabled/default
Restart services for running WebVirtCloud:
sudo service nginx restart
sudo service supervisor restart
Setup libvirt and KVM on server
wget -O - https://bit.ly/36baWUu | sudo sh
Done!!
Go to http://serverip and you should see the login screen.

Add the following after the [include] line (after files = ... actually):
sudo vim /etc/supervisord.conf
[program:webvirtcloud]
command=/srv/webvirtcloud/venv/bin/gunicorn webvirtcloud.wsgi:application -c /srv/webvirtcloud/gunicorn.conf.py
directory=/srv/webvirtcloud
user=nginx
autostart=true
autorestart=true
redirect_stderr=true
[program:novncd]
command=/srv/webvirtcloud/venv/bin/python3 /srv/webvirtcloud/console/novncd
directory=/srv/webvirtcloud
user=nginx
autostart=true
autorestart=true
redirect_stderr=true
You will need to edit the main nginx.conf file as the one that comes from the rpm's will not work. Comment the following lines:
# server {
# listen 80 default_server;
# listen [::]:80 default_server;
# server_name _;
# root /usr/share/nginx/html;
#
# # Load configuration files for the default server block.
# include /etc/nginx/default.d/*.conf;
#
# location / {
# }
#
# error_page 404 /404.html;
# location = /40x.html {
# }
#
# error_page 500 502 503 504 /50x.html;
# location = /50x.html {
# }
# }
}
Also make sure file in /etc/nginx/conf.d/webvirtcloud.conf has the proper paths:
upstream gunicorn_server {
#server unix:/srv/webvirtcloud/venv/wvcloud.socket fail_timeout=0;
server 127.0.0.1:8000 fail_timeout=0;
}
server {
listen 80;
server_name servername.domain.com;
access_log /var/log/nginx/webvirtcloud-access_log;
location /static/ {
root /srv/webvirtcloud;
expires max;
}
location / {
proxy_pass http://gunicorn_server;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-for $proxy_add_x_forwarded_for;
proxy_set_header Host $host:$server_port;
proxy_set_header X-Forwarded-Proto $remote_addr;
proxy_connect_timeout 1800;
proxy_read_timeout 1800;
proxy_send_timeout 1800;
client_max_body_size 1024M;
}
}
Change permissions so nginx can read the webvirtcloud folder:
sudo chown -R nginx:nginx /srv/webvirtcloud
Change permission for selinux:
sudo semanage fcontext -a -t httpd_sys_content_t "/srv/webvirtcloud(/.*)"
sudo setsebool -P httpd_can_network_connect on -P
Add required user to the kvm group(if you not install with root):
sudo usermod -G kvm -a <username>
Allow http ports on firewall:
sudo firewall-cmd --add-service=http
sudo firewall-cmd --add-service=http --permanent
sudo firewall-cmd --add-port=6080/tcp
sudo firewall-cmd --add-port=6080/tcp --permanent
Let's restart nginx and the supervisord services:
sudo systemctl restart nginx && systemctl restart supervisord
And finally, check everything is running:
sudo supervisorctl status
gstfsd RUNNING pid 24662, uptime 6:01:40
novncd RUNNING pid 24661, uptime 6:01:40
webvirtcloud RUNNING pid 24660, uptime 6:01:40
WSGIDaemonProcess webvirtcloud threads=2 maximum-requests=1000 display-name=webvirtcloud
WSGIScriptAlias / /srv/webvirtcloud/webvirtcloud/wsgi_custom.py
wget -O - https://clck.ru/9V9fH | sudo sh
Done!!
Go to http://serverip and you should see the login screen.
Alternative to running nonvcd via supervisor is runit.
On Debian systems install runit and configure novncd service:
apt install runit runit-systemd
mkdir /etc/service/novncd/
ln -s /srv/webvirtcloud/conf/runit/novncd.sh /etc/service/novncd/run
systemctl start runit.service
login: admin
password: admin
This is a short example of configuring cloud and compute side of the ssh connection.
On the webvirtcloud machine you need to generate ssh keys and optionally disable StrictHostKeyChecking.
chown www-data -R ~www-data
sudo -u www-data ssh-keygen
cat > ~www-data/.ssh/config << EOF
Host *
StrictHostKeyChecking no
EOF
chown www-data -R ~www-data/.ssh/config
You need to put cloud public key into authorized keys on the compute node. Simpliest way of doing this is to use ssh tool from the webvirtcloud server.
sudo -u www-data ssh-copy-id root@compute1
If you see warning
Unsupported configuration: Host SMBIOS information is not available
Then you need to install dmidecode package on your host using your package manager and restart libvirt daemon.
Debian/Ubuntu like:
sudo apt-get install dmidecode
sudo service libvirt-bin restart
Arch Linux
sudo pacman -S dmidecode
systemctl restart libvirtd
Currently supports only root ssh authorized keys and hostname. Example configuration of the cloud-init client follows.
datasource:
OpenStack:
metadata_urls: [ "http://webvirtcloud.domain.com/datasource" ]
Edit WS_PUBLIC_PORT at settings.py file to expose redirect to 80 or 443. Default: 6080
WS_PUBLIC_PORT = 80
# Go to Installation Directory
cd /srv/webvirtcloud
source venv/bin/activate
git pull
pip3 install -U -r conf/requirements.txt
python3 manage.py migrate
sudo service supervisor restart
Server on which tests will be performed must have libvirt up and running.
It must not contain vms.
It must have default storage which not contain any disk images.
It must have default network which must be on.
Setup venv
python -m venv venv
source venv/bin/activate
pip install -r conf/requirements.txt
Run tests
python manage.py test
