How Abiquo supports remote access to VMs
To connect to a VM, the user clicks the console
button on the VM control panel
. The platform opens a connection to the VM using the appropriate protocol, for example, VNC, RDP, or SSH.
By default Abiquo uses Apache Guacamole https://guacamole.incubator.apache.org/ as a remote access server, and it is installed on the Remote Services server. When you configure a datacenter or public cloud region, the platform automatically adds the remote service, and you can share it with other datacenters or providers. Guacamole supports VNC, RDP, and SSH connections using a single solution for all protocols.
When a user requests remote access to a VM:
- The platform registers an event with the action name "VIRTUAL_MACHINE_REQUEST_ACCESS".
- The Abiquo Server supplies a link to the VM connection via the Guacamole server.
- The Abiquo UI loads the Guacamole client, which opens the remote access link.
- The platform requests the remote access password or SSH key
For VMware, Abiquo also supports WebMKS.
- vCloud uses WebMKS only
- vCenter uses WebMKS with WebMKS proxy, as an alternative to VNC via Guacamole
Brand the Guacamole client
To brand the Guacamole client:
- Copy the stylesheet from theme/default/css/theme_guacamole.css to your theme
- Modify it as required
For more details, see Abiquo Branding Guide
Configure remote access in private cloud
The following configuration applies to private cloud and non-WebMKS access:
- For vCenter clusters added as physical machines, optionally set properties to define how the platform should detect host IPs used for management traffic to assign host IPs for remote access. See Abiquo Configuration Properties#esxi. See Add VMware vCenter clusters as servers
- Optionally configure the port range for VNC if you would like to modify the platform default of 5900 to 65534. In general, VNC connections should use ports 5900 to 6000. VMware only recommends ports 5900 to 5964. See VMware Documentation
- Optionally configure keymaps for ESXi. To set a default keymap value for the platform, Abiquo Configuration Properties#vnc
Disable or enable remote access for the platform
These instructions apply to remote access from the console button using Guacamole. Remote access using WebMKS is always enabled
By default, remote access is enabled for the whole platform.
To change the remote access configuration for the platform:
- Log in to the Abiquo UI and go to Configuration → Infrastructure.
- Set the property to Allow remote access to virtual machines as required.
The state of remote access will change for VMs that are NOT deployed. Deployed VMs will keep their original state.
- After you disable remote access for VMs on hypervisors, users cannot access deployed VMs through the console button but the port is still enabled, so users can connect with another client.
Configure VM templates for remote access
For VM templates:
- Administrators can set a default VM user and password for SSH connections.
- With a compatible template, users can request an initial VM password using guest setup, which will be sent to them by email or SMS. See Guest setup
Configure user accounts for remote access
To enable remote access, user accounts should have the following:
- SSH public key
- Email address
- Telephone number (cell phone)
For public cloud, users must assign the following to their VMs:
- A public IP
- A firewall that allows the appropriate type of connection for the VM (for example, SSH connections to Linux VMs and RDP connections to Windows VMs)
VM settings for remote access
WebMKS for vCenter
If remote access to VMs is enabled to use VNC, you can change it to use WebMKS.
To configure WebMKS for vCenter do these steps:
- Install WebMKS proxy
- Optionally brand WebMKS. See Branding WMKS
- Enable WebMKS for vCenter
