Managing Tesla

To interact with Tesla, you'll need a Windows OS, and the VMware vSphere Client. If you have Windows, you can get the client directly from Tesla. All tasks require that you open the vSphere client, and sign in to tesla.usability.wikimedia.org.

Rebooting virtual machines

From the Home view:

  1. Click "Inventory"
  2. Expand tesla.usability.wikimedia.org
  3. Right click on the VM you wish to reboot
    1. Under "Power", select "Restart guest" (CTRL-r); if this fails, select "Reset" (CTRL-t)

Note: "Reset" is like a hardware reset. The guest OS will not shut down properly, and could get corrupted when doing so. It should be used only when necessary. If the guest has panic'd, for instance, this will be the only option.

VMware tools

It is important to keep the VMware tools up to date on all of the guests. The tools add faster network adapters, better disk drivers, etc. They also allow the ESXi host to suspend the VMs when rebooting (important for patching). Whenever a new kernel is installed on a guest, you will need to update the VMware tools. See the below instructions: 

yum -y install gcc kernel-devel patch make
mount /media/cdrom
cp /media/cdrom/VMware*.tar.gz /tmp
cd /tmp
tar -xzvf VMware*.tar.gz
cd vmware-tools-distrib
./vmware-installer.pl
<accept all defaults>

User documentation

Backend servers

Backend servers are servers that only have a private IP address.

  • Backend servers do not have access to anything on the public internet, except through a web proxy. The web proxy has a whitelist for what it is allowed to access, so if you need access to a specific domain, you'll need to request it.
  • Backend servers also have a disconnected, shared, public IP address that can be enabled for short periods of time, when requested. The public IP address can only be enabled by VM admins.

Resources

Resources for a VM are: number of CPUs, RAM, and storage space.

  • Most resources can be added and removed as needed for most operating systems
  • Resources are limited, and are allocated by need. If you need more resources, please provide justification when requesting.
