- The UML driver for libvirt allows use and management of paravirtualized - guests built for User Mode Linux. UML requires no special support in - the host kernel, so can be used by any user of any linux system, provided - they have enough free RAM for their guest's needs, though there are - certain restrictions on network connectivity unless the administrator - has pre-created TAP devices. -
- -- The libvirt UML driver follows the QEMU driver in providing two - types of connection. There is one privileged instance per host, - which runs as root. This is called the "system" instance, and allows - full use of all host resources. Then, there is a per-user unprivileged - "session", instance. This has more restricted capabilities, and may - require the host administrator to setup certain resources ahead of - time to allow full integration with the network. Example connection - URIs are -
- --uml:///session (local access to per-user instance) -uml+unix:///session (local access to per-user instance) - -uml:///system (local access to system instance) -uml+unix:///system (local access to system instance) -uml://example.com/system (remote access, TLS/x509) -uml+tcp://example.com/system (remote access, SASl/Kerberos) -uml+ssh://root@example.com/system (remote access, SSH tunnelled) -- -
- User mode Linux driver only supports directly kernel boot at - this time. A future driver enhancement may allow a paravirt - bootloader in a similar style to Xen's pygrub. For now though, - the UML kernel must be stored on the host and referenced - explicitly in the "os" element. Since UML is a paravirtualized - technology, the kernel "type" is set to "uml" -
- -- There is not yet support for networking in the driver, but - disks can be specified in the usual libvirt manner. The main - variation is the target device naming scheme "ubd0", and - bus type of "uml". -
- -- Once booted the primary console is connected to a PTY, and - thus accessible with "virsh console" or equivalent tools -
