Webvirtmgr на Debian Jessie. Веб интерфейс для Linux KVM

Установка необходимых пакетов:

aptitude update
aptitude install git python-pip python-libvirt python-libxml2 novnc supervisor qemu-kvm libvirt-bin virtinst sasl2-bin bridge-utils 
insserv nginx

Настраиваем KVM

vim /etc/default/libvirtd:

libvirtd_opts="-d -l"

vim /etc/libvirt/libvirtd.conf:

listen_tls = 0
listen_tcp = 1

invoke-rc.d libvirtd restart

Делаем сетевой мост для KVM

vim /etc/network/interfaces:

auto br0
allow-hotplug br0
iface br0 inet static
       address 192.168.10.1
       gateway 192.168.10.1
       bridge_ports eth0
       bridge_stp off
       bridge_maxwait 0

invoke-rc.d networking stop && invoke-rc.d networking start

Настраиваем webvirtmgr

cd /var/www
git clone git://github.com/retspen/webvirtmgr.git

или просто скачиваем архив: webvirtmgr

cd webvirtmgr
pip install -r requirements.txt
./manage.py syncdb
./manage.py collectstatic
vim conf/gunicorn.conf.py:

bind = '0.0.0.0:8000'

chown -R www-data:www-data /var/www/webvirtmgr

Добавляем пользователя, который получит доступ к веб интерфейсу

/var/www/webvirtmgr/manage.py createsuperuser

Потом для того же пользователя

saslpasswd2 -a libvirt user

Статус пользователей

sasldblistusers2 -f /etc/libvirt/passwd.db

vim /etc/supervisor/conf.d/webvirtmgr.conf:

[program:webvirtmgr]
command=/usr/bin/python /var/www/webvirtmgr/manage.py run_gunicorn -c /var/www/webvirtmgr/conf/gunicorn.conf.py
directory=/var/www/webvirtmgr
autostart=true
autorestart=true
stdout_logfile=/var/log/supervisor/webvirtmgr.log
redirect_stderr=true
user=www-data 

[program:webvirtmgr-console]
command=/usr/bin/python /var/www/webvirtmgr/console/webvirtmgr-console
directory=/var/www/webvirtmgr
autostart=true
autorestart=true
stdout_logfile=/var/log/supervisor/webvirtmgr-console.log
redirect_stderr=true
user=www-data 

invoke-rc.d supervisor restart
invoke-rc.d supervisor restart

invoke-rc.d novnc stop
insserv -r novnc
vim /etc/insserv/overrides/novnc:

#!/bin/sh
### BEGIN INIT INFO

Настраиваем доступ по ключу ssh

su -s /bin/bash www-data
ssh-keygen
ssh-copy-id root@YOUR_KVM_HOST
you need to accept add key
exit

Настраиваем доступ на хост для webvirtmgr через nginx

mcedit /etc/nginx/sites-available/webkvm

server {
    listen      192.168.1.3:88;
    server_name $hostmane;
    location /static/ {
        root /home/www/webvirtmgr/webvirtmgr; # or /srv instead of /var
        expires max;
    }

    location / {
        proxy_pass http://127.0.0.1:8000;
        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 $scheme;
        proxy_connect_timeout 600;
        proxy_read_timeout 600;
        proxy_send_timeout 600;
        client_max_body_size 1024M; # Set higher depending on your needs 
    }
}

Открываем порты

iptables -I INPUT 1 -m state --state RELATED,ESTABLISHED -j ACCEPT
iptables -I INPUT 2 -s 192.168.10.0/24 -d 192.168.10.1 -i eth0 -p tcp -m state --state NEW -m multiport --dports 80,6080,8000,16509 -j ACCEPT
invoke-rc.d iptables save

Веб интерфейс будет доступен по адресу http://example.com:8000
