WebVirtMgr
Setting up the server to work with the service
ContOS, Fedora, RedHat
Install packages libvirt-bin, KVM
# yum -y install kvm libvirt
Ubuntu, Debian
Install packages libvirt-bin, KVM, sasl2-bin
$ sudo apt-get install kvm libvirt-bin sasl2-bin
ContOS, Fedora, RedHat
Uncomment the line in the file /etc/sysconfig/libvirtd
LIBVIRTD_ARGS="--listen"
Ubuntu, Debian
Add the option -l in the file /etc/default/libvirt-bin
libvirtd_opts="-d -l"
Ubuntu, Debian, Fedora, CentOS, RedHat
The file /etc/libvirt/libvirtd.conf uncomment the line
listen_tls = 0 listen_tcp = 1
ContOS, Fedora, RedHat
Start the daemon libvirtd
# service libvirtd start
Ubuntu, Debian
Restart the daemon libvirtd, because after installation it runs automatically
$ sudo service libvirt-bin restart
Adding users and setting their passwords is done with the saslpasswd2 command. When running this command it is important to tell it that the appname is libvirt. As an example, to add a user fred, run
ContOS, Fedora, RedHat
# saslpasswd2 -a libvirt fred Password: xxxxxx Again (for verification): xxxxxx
Ubuntu, Debian
$ sudo saslpasswd2 -a libvirt fred Password: xxxxxx Again (for verification): xxxxxx
To see a list of all accounts the sasldblistusers2 command can be used. This command expects to be given the path to the libvirt user database, which is kept in/etc/libvirt/passwd.db
ContOS, Fedora, RedHat
# sasldblistusers2 -f /etc/libvirt/passwd.db fred@webvirtmgr.net: userPassword
Ubuntu, Debian
$ sudo sasldblistusers2 -f /etc/libvirt/passwd.db fred@webvirtmgr.net: userPassword
To disable a user's access, use the command saslpasswd2 with the -d
ContOS, Fedora, RedHat
# saslpasswd2 -a libvirt -d fred
Ubuntu, Debian
$ sudo saslpasswd2 -a libvirt -d fred
Configuring the firewall
ContOS, Fedora, RedHat
Open access to ports libvirt
# iptables -I INPUT -m state --state NEW -m tcp -p tcp --dport 16509 -j ACCEPT
Ubuntu, Debian
Create a file /etc/ufw/applications.d/libvirtd and it add the following lines
[Libvirt] title=Virtualization library description=Open port for WebVirtMgr ports=16509/tcp
Add a firewall rule in the chain
$ sudo ufw allow from any to any app Libvirt
Test connection
Before you add the ip address of your server in the control center perform the following test
$ virsh -c qemu+tcp://IP_address/system nodeinfo Please enter your authentication name: fred Please enter your password: xxxxxx CPU model: x86_64 CPU(s): 2 CPU frequency: 2611 MHz CPU socket(s): 1 Core(s) per socket: 2 Thread(s) per core: 1 NUMA cell(s): 1 Memory size: 2019260 kB
