6.3 Managing virtual machines with UVMM<br />
NAT network cards are defined in a private network on the virtualisation server. To do so, the virtual<br />
machine(s) must be assigned an IP address from the 192.168.122.0/24 network. This virtual instance is<br />
granted the access to the external network via NAT, so that the access is performed via the virtualisation<br />
server’s IP address.<br />
The UVMM servers are already preconfigured for both types of network cards. However, there are restric-<br />
tions for bridged network cards. On the UVMM servers, the physical network card to which the standard<br />
route is set, is converted to a bridge in the default setting. If additional network cards are integrated in<br />
the server, these are not adapted accordingly. If several bridge network cards are required in a virtual<br />
instance, an additional network card must be configured as a bridge on the server in advance. If a bridge<br />
is used, the Source of the network interface used can be selected.<br />
NAT network cards are only restricted by the IP addresses available in the 192.168.122.0/24 network.<br />
The Driver can be used to select what type of card will be provided. The Realteak RTL-8139 is supported<br />
by almost all operating systems, the Intel Pro-1000 offers advanced abilities and a Paravirtual device<br />
offers the best performance.<br />
The MAC address is generated automatically, but may also be subsequently changed.<br />
6.3.2.5 Settings<br />
The basic settings of a virtual machine can only be changed if it is turned off.<br />
Name defines the name of the virtual machine. This does not have to be the same as the name of the<br />
host in the LDAP directory.<br />
Operating System can contain a description of the virtual instance or of the operating system used.<br />
Contact defines the contact person for the virtual machine, e.g., in the form of an e-mail address.<br />
Description can describe the function of the virtual machine, e.g. mail server.<br />
Architecture specifies the architecture of the emulated hardware. It must be noted that virtual 64 bit<br />
machines can only be created on virtualisation servers using the amd64 architecture. This setting is<br />
not shown on i386 systems.<br />
Number of CPUs defines how many virtual CPUs are assigned to the virtual instance.<br />
Memory specifies the size of the system memory.<br />
6.3.2.6 Extended settings<br />
The extended settings of a virtual machine can only be changed if it is turned off.<br />
Virtualization Technology shows the technology used for virtualisation. This setting can only be speci-<br />
fied when creating a virtual instance.<br />
Boot order specifies the order in which the emulated BIOS of the virtual machine searches the drives<br />
for bootable media. This setting is only available for fully-virtualised instances. In paravirtualised<br />
instances, the Set as boot device option can be used in the drive settings.<br />
