================================== Virtual & Cloud based Installation ================================== ------------ Local/Server ------------ Installing OPNsense on a virtual machine can be done by using the DVD ISO image. Full instructions are available in chapter :doc:`install` . General tips ------------ For optimum performance and compatibility, these guides are given: * Minimum required RAM is 1 GB * Minimum recommended virtual disk size of 8 GB * Disable all off-loading settings in **Interfaces->Settings** .. image:: images/disableoffloading.png ------------------ VMware ESXi ----------- VMware offers full instructions for installing FreeBSD, these can be found `here `__. To install the VMware tools just goto **System->Firmware->Plugins** and install **os-vmware** by clicking on the **+** sign next to it. .. image:: images/os-vmware.png .. Note:: While other network setups may work fine, the e1000 driver seems to work best, certainly when utilizing the traffic shaper. ------------------ Xen --- To install the Xen tools just goto **System->Firmware->Plugins** and install **os-xen** by clicking on the **+** sign next to it. .. image:: images/os-xen.png ------------------ HyperV ------ HyperV Generation 1 and 2 are supported out of the box, no additional drivers or tools are needed. Others ------ OPNsense can be installed on all virtual machines that support FreeBSD (such as KVM, Bhyve, VirtualBox). ------------------ ------ Hosted ------ For hosted installations where you can't install using the DVD ISO an alternative approach is available in the form of **opnsense-bootstrap**. opnsense-bootstrap ------------------ opnsense-bootstrap(8) is a tool that can completely reinstall a running system in place for a thorough factory reset or to restore consistency of all the OPNsense files. It can also wipe the configuration directory, but won't do that by default. It will automatically pick up the latest available version and build a chain of trust by using current package fingerprints -> CA root certificates -> HTTPS -> OPNsense package fingerprints. What it will also do is turn a supported stock FreeBSD release into an OPNsense installation, given that UFS was used to install the root file system. opnsense bootstrap is available for our `github source repository `__ ------------------ -------------------- Amazon AWS EC2 Cloud -------------------- .. image:: how-tos/images/amazon-web-services.png :width: 100% Installing OPNsense into the Amazon cloud can be a dounting task as no console is offered. As part of Deciso's support packages (see `OPNsense commercial Support `__), deciso offer free access to its OPNsense Amazon Machine Image (AMI). See also our how-to for :doc:`how-tos/installaws`. ------------- Common Issues ------------- Some common issues have been reported for different virtual environments. You can find known solutions to these problems below. If you problem is not listed always try the General tips as mentioned in the article first. ------------------ File copy failed during installation ------------------------------------ This issue is most likely caused by low memory setting. Make sure your virtual OPNsense installation has a minimum of 1 GB of RAM. ------------------ Disk Errors on VMware ----------------------- This issue can be caused by a defective drive. Changing drive mode to IDE has been reported to help for certain ESXi versions. ------------------ Installation failure on KVM --------------------------- If you are using virtio for the root disk then try switching to sata mode. ------------------ NAT issues on XenServer ----------------------- This issue has been reported to be solved by disabling cheksum offloading on both OPNsense domU and Vifs. ------------------ Traffic Shaper does not work on VMware -------------------------------------- If you are using vmxnet3 drivers try to switch to E1000.
