Configuring Linux-based Virtual Machines

After installing a Linux-based virtual machine, configure the additional resources and software necessary for production use, as described in:

• Creating and Initializing a Disk (Linux-based VMs)
• Installing Applications (Linux-based VMs)

In addition, ensure that you configure the following settings:

• Disable hibernation (enabled by default in some cases) to prevent the guest operating system from going into a power-saving state.
• Install the kexec-tools package and configure the guest operating system to generate a crash dump file if the system crashes.
• If the guest operating system is Ubuntu Linux:
  • To prevent a problem where the VM console hangs in everRun Availability Console, edit the /boot/grub/grub.cfg file and change the gfxmode parameter to text (for example, set gfxmode=text). If the VM console hangs on first boot, keep restarting the VM until the console opens properly in everRun Availability Console and then modify the gfxmode parameter to prevent subsequent issues.
  • For the minimal server version of Ubuntu, optionally install the acpid package to enable the Shutdown button in everRun Availability Console, as described in Shutting Down a Virtual Machine.

For more information about these settings, see your Linux documentation.
