Create new KVM guest entry. KVM guest cannot change. If guest where disabled before - KVM guest is automatically started. Print or save an export script that can be used to restore configuration of current sub-menu, KVM guest configuration, image files will not be saved. Also, all the additional files created in KVM guest will be stored in file image. This image file is not connected to host RouterOS and user is able to run different RouterOS versions on host and guest.
After KVM guest is shut-downed it will be automatically started by host when shut down is complete. Parameters: file-name - name of ROS image to be reconfigured; configuraton-script - file name where configuration script is located; configuration-string - string containing ROS commands to be configured on ROS image.
MAC address of virtual interface that host will use. Available options are: virtio - default value. Fastest available option, should be chosen if no other problems are encountered e - emulates card that uses e driver. This option where added for compatibility with some guest operating systems that where not able to communicate with host RouterOS if virtio interface model where used.
MAC address of virtual interface that guest will use. Ensure that the libvirt-daemon-config-network package is installed:.
Verify that the libvirt default network is active and configured to start automatically:. If activating the default network fails with the following error, the libvirt-daemon-config-network package has not been installed correctly.
To fix this, re-install libvirt-daemon-config-network. To fix this, use the virsh net-edit default command and change the The following sections provide information on how to use the RHEL 8 web console to create VMs and install guest operating systems on them. To create a virtual machine VM on the host machine to which the web console is connected, follow the instructions below. The VM is created. If the Immediately Start VM checkbox is selected, the VM will immediately start and begin installing the guest operating system.
To create a virtual machine VM by importing a disk image of an existing VM installation, follow the instructions below.
The first time a virtual machine VM loads, you must install an operating system on the VM. A new page opens with basic information about the selected VM and controls for managing various aspects of the VM. Optional : Change the firmware. The installation routine of the operating system runs in the VM console.
You can use the command line interface to start a shut-down virtual machine VM or restore a saved VM. Follow the procedure below. For a local VM, use the virsh start utility. For example, the following command starts the demo-guest1 VM. For example, the following command starts the demo-guest1 VM on the In the Virtual Machines interface, click the VM you want to start.
A new page opens with detailed information about the selected VM and controls for shutting down and deleting the VM. The VM starts, and you can connect to its console or graphical output. Optional: To set up the VM to start automatically when the host starts, click the Autostart checkbox.
If you use network interfaces that are not managed by libvirt, you must also make additional changes to the systemd configuration. Otherwise, the affected VMs might fail to start, see starting virtual machines automatically when the host starts.
When a host with a running virtual machine VM restarts, the VM must be started again manually by default. However, you might want your VM to be always available when the host is running. In that case, you can use the virsh autostart utility to configure the VM to be started automatically.
Use the virsh autostart utility to configure the VM to start automatically when the host starts. For example, the following command configures the demo-guest1 VM to start automatically.
Otherwise, the affected VMs might fail to start. In the systemd configuration directory tree, create a libvirtd. Create a network-online. The content of this file overrides the default systemd configuration for libvirtd service. Add the following lines to the network-online. This configuration change ensures systemd starts libvirtd service only after the network on the host is ready. View the VM configuration, and check that the autostart option is enabled. For example, the following command displays basic information about the demo-guest1 VM, including the autostart option.
If you use network interfaces that are not managed by libvirt, check if the content of the network-online. If the VMs to which you are connecting are on a remote host rather than a local one, you can optionally configure your system for more convenient access to remote hosts. These include both graphical and serial consoles.
In the Virtual Machines interface, click the VM whose graphical console you want to view. A new page opens with an Overview and a Console section for the VM. Select VNC console in the console drop down menu. You can now interact with the VM console using the mouse and keyboard in the same manner you interact with a real machine. The display in the VM console reflects the activities being performed on the VM. To send such key combinations, click the Send key menu and select the key sequence to send.
Using the web console interface, you can display the graphical console of a selected virtual machine VM in a remote viewer, such as Virt Viewer. You can launch Virt Viewer from within the web console.
Before you can view the graphical console in Virt Viewer, you must install Virt Viewer on the machine to which the web console is connected. Remote Viewer is available on most operating systems. However, some browser extensions and plug-ins do not allow the web console to open Virt Viewer. Select Desktop Viewer in the console drop down menu. You can interact with the VM console using the mouse and keyboard in the same manner you interact with a real machine.
If launching the Remote Viewer in the web console does not work or is not optimal, you can manually connect with any viewer application using the following protocols:. This is useful when the host machine or the VM is not configured with a graphical interface. For more information about the serial console, see Section 2. In the Virtual Machines pane, click the VM whose serial console you want to view.
Select Serial console in the console drop down menu. To connect to a graphical console of a KVM virtual machine VM and open it in the Virt Viewer desktop application, follow the procedure below. To connect to a local VM, use the following command and replace guest-name with the name of the VM you want to connect to:. For example, the following command connects as root to a VM called guest-name , located on remote system The connection also requires root authentication for If the connection works correctly, the VM display is shown in the Virt Viewer window.
To interact with the terminal of a virtual machine VM using the SSH connection protocol, follow the procedure below:. If it is not, do the following:. The following example demonstrates connecting to a host machine Note, the IP address must correspond to libvirt's default network address. See the ip -tag in the network configuration above. Now, restart the host's NetworkManager with sudo systemctl restart NetworkManager From now on the guests can be accessed using their hostnames, like ssh vm1.
After the configuration, you can set using interface dummy0 macvtap in bridged mode as the network configuration in VM guests configuration. After the configuration, you can set using Bridge Interface br0 as the network connection in VM guest configuration. VMs can be generated using virtinst. For more details see the libvirt page. Virtual machines can also be controlled using the kvm command in a similar fashion to QEMU. This file specifies whether guests should be shutdown or suspended, if they should be restarted on host startup, etc.
The first parameter defines where to find running guests. Adjust the number of lines of vcpupin to reflect the vcpu count and cpuset to reflect the actual physical cpu core allocation. In general, the higher half physical CPU core are the hyperthreading cores which cannot provide full core performance while have the benefit of increasing the memory cache hit rate.
