Setting Up for Linux Desktops

PowerCLI SSH
No need to install additional tools.

For Ubuntu, you need to install the SSH server with the command
sudo apt-get install openssh-server. For RHEL and CentOS,
openssh-server is installed by default but you need to ensure that the
firewall settings allow ssh.
n
Need to download the SSH client applications pscp.exe and
plink.exe and put them in the same folder as the PowerCLI scripts.

Can handle special characters in the administrator's password when
running the script to install Horizon Agent or the AD user's password
when running the script to join the domain.
NOTE Both PowerCLI-based and SSH-based scripts can handle special characters in the passwords for the
vCenter Server administrator and the Linux administrator. PowerCLI-based scripts can also handle special
characters in the ESXi host administrator's password. In all these cases, an escape character is not necessary.

The process of bulk deploying a pool of Linux desktops involves the following steps:
1 Create a virtual machine template.
See “Create a Virtual Machine Template for Cloning Linux Desktop Machines,” on page 53.
2 Create a guest customization specification.
See "Create a Customization Specification for Linux in the vSphere Web Client" in the vSphere Virtual
Machine Administration document. When you create the specification, make sure that you specify the
following settings correctly.
Setting Value
Target Virtual Machine OS Linux
Computer Name Use the virtual machine name.
Domain Specify the domain of the View environment.
Network Settings Use standard network settings.
Primary DNS Specify a valid address.
NOTE For more information on Guest OS Customization Support Matrix, see
http://partnerweb.vmware.com/programs/guestOS/guest-os-customization-matrix.pdf.
3 Clone virtual machines.
See “Sample Script to Clone Linux Virtual Machines,” on page 55.
4 Join the cloned VMs to the Active Directory (AD) domain.
See “Sample Script to Join Cloned Virtual Machines to AD Domain,” on page 59 or “Sample Script to
Join Cloned Virtual Machines to AD Domain Using SSH,” on page 61.
5 Install Horizon Agent in virtual machines.
