Example: Creating a Windows VM

The steps mentioned above can also be applied to the creation of a Windows VM. Please ensure thta you have uploaded a Windows ISO first: Uploading an Image

Wählen Sie zunächst Create VM und legen Sie einen Namen für die VM fest:



Wählen Sie als Betriebssystem-Art die entsprechende Windows-Version aus:



Wählen Sie unter ISO-Image das entspechende Windows-Image aus, welches Sie vorher hochgeladen haben:


Legen Sie nun die Einstellungen für die virtuelle Festplatte fest. Wählen Sie bei BUS/Device SATA und legen Sie bei Disk size (GB) die Größe der virtuellen Festplatte fest:



Unter CPU wählen Sie die Anzahl der virtuellen CPUs sowie der Kerne aus:



Unter Memory setzen Sie den verfügbaren Arbeitsspeicher:



Unter Network belassen Sie die Standard-Einstellungen (Bridged mode):



Bestätigen Sie die Einstellungen mit einem Klick auf Finish:



Rechtsklicken Sie in der Übersicht auf die VM und wählen Sie Start, um die VM zu starten:



Rechtsklicken Sie erneut auf die VM und wählen Sie Console, um die graphische Ausgabe der VM umzuleiten:



Sie sehen nun den Installationsbildschirm:



Führen Sie abschließend wie gewohnt die Windows-Installation durch. Bitte beachten SIe, das SIe nach der Installation noch die individuelle Netzwerk-Konfiguration (Zuweisen der IP-Adresse etc.) innerhalb der VM vornehmen müssen.

Creating an OpenVZ container

With Proxmox you have the possibility to create an OpenVZ container. To do this click on storage in the 'Server View'.

Datei:proxmox_openvz1_en.png


Click the Content tab.

Datei:proxmox_openvz2_en.png


Select the tab Templates to download a template.

Datei:proxmox_openvz3_en.png


Select a template (in this case centos-6-standard) and click Download.

Datei:proxmox_openvz4_en.png


After the download has finished, the following output appears:

Click the Create CT button to create an OpenVZ container.

Datei:proxmox_openvz6_en.png


In the following window individual settings for the OpenVZ container can be set up. Enter a name for the CT and assign a password.

Datei:proxmox_openvz7_en.png


Select the downloaded template that you want to use for the new CT.

Datei:proxmox_openvz8_en.png


Set the ressources of your container. These include memory, disk size, swap and number of the CPUs.

Datei:proxmox_openvz9_en.png


On the tab Network choose between Routed mode or Bridged mode. Confirm your choice with Next.

Datei:proxmox_openvz10_en.png


Here your DNS settings can be configured.

Datei:proxmox_openvz11_en.png


Finally you will be presented with a confirmation window that gives you a summary of all the settings you have made.

Datei:proxmox_openvz12_en.png


Finished! You have created an OpenVZ container, displayed in the 'Server View'.

Datei:proxmox_openvz13_en.png


To start the OpenVZ container click on Start. If you want to shutdown your CT click on Shutdown. To stop your container click on Stop.

Configuration OpenVZ routed

If you want to use Proxmox OpenVZ VMs with routed networking, some additional configuration is needed.

Activate IP-forwarding :

echo 'net.ipv4.ip_forward=1' >> /etc/sysctl.conf
echo 'net.ipv6.conf.all.proxy_ndp=1' >> /etc/sysctl.conf 

Configure OpenVZ for the use of multiple subnets on the same network interface:

/etc/vz/vz.conf

# Controls which interfaces to send ARP requests and modify APR tables on.
NEIGHBOUR_DEVS=all

Configuration of IPv6

Preparations

To use IPv6 for your virtual machines or OpenVZ containers you must set up the free contained IPv6 /64 net via the support. Send an accordingly request to EUserv Support.

The IPv6 net will be routed via the main IPv6 address of your server. If you don't have created the main IPv6 address, please follow these steps:

Creating the IPv6 addresses

Configuration of the host system

You need the main IPv6 address and the associated IPv6 gateway for configuration of the host system. In the customer service center both data can be found by clicking on IPv6 addresses.

Assign the main IPv6 address of your server to the active network interface ('vmbr0' in the default installation) and create the default gateway:

ip -6 addr add <IPv6 main address> dev vmbr0
route -A inet6 add default gw <IPv6 gateway>

Next, test the IPv6 connectivity:

ping6 ipv6.google.com

If you get a positive result, make the changes in /etc/network/interfaces persistent (add the following lines):

iface vmbr0 inet6 static
       address   <IPv6 main address> 
       netmask   64
       gateway   <IPv6 gateway>

Next, IPv6 forwarding must be activated and the changes applied to the kernel:

echo 'net.ipv6.conf.all.proxy_ndp=1' >> /etc/sysctl.conf 
echo 'net.ipv6.conf.all.forwarding=1' >> /etc/sysctl.conf
sysctl -p

Make sure that in /etc/bz/vz.conf the following is included (i.e. not commented):

IPV6="yes"

Configuration of the guest system (OpenVZ)

Now you can assign the IPv6 addresses from the /64 subnet to your virtual machines. The webinterface of Proxmox can only handle IPv4 addresses, so the configuration must be made via the terminal in the host system. The first three addresses are (supposing the /64 net is 2001:db8:beef:1001::/64):

 2001:db8:beef:1001::1
 2001:db8:beef:1001::2
 2001:db8:beef:1001::3
           .
           .
           .

Repeat the following step vor all VMs that you want to assign an IP:

vzctl set <container_id> --ipadd <IPv6-Adresse> --save

Subsequently start the VM. The connectivity should now be established:

vzctl start <container_id>
(this step can also be done via the webinterface)

Configuration of the guest system (KVM/routed)

Hint: The bridged network configuration is needed for the assignment of IPv6 addresses from the /64 subnet.

First assign an IPv6 address from the /64 subnet to the network interface in the VM (replace the example address with the actual address you are planning to assign):

ip -6 addr add 2001:db8:beef:1001::1/64 dev eth0

Set the default gateway (the IPv6 main address of your server):

route -A inet6 add default gw <IPv6 main address>/64

Finally, you have to create the corresponding route on the host to the virtual machines:


ip -6 route add 2001:db8:beef:1001::1 dev vmbr0
ip -6 route add 2001:db8:beef:1001::2 dev vmbr0
ip -6 route add 2001:db8:beef:1001::3 dev vmbr0
           .
           .
           .

Test the connectivity with a ping6 or SSH access to your VM.
