NAME
virt-install - install guest operating system on xVM system
SYNOPSIS
/usr/bin/virt-install [options]
DESCRIPTION
The virt-install program enables you to install a guest operating system on a machine running Solaris xVM.
virt-install allows you to enter information about a guest either as a set of command-line options or in response to a series of prompts.
When run without options, virt-install takes you through a series of prompts, for which you need to know the information listed below. This
information maps to the command options, described in their own section.
o Name of your guest domain. This name serves as the label of the guest operating system and will be the name of the file that
stores the guest's configuration. For network-based installs, the name of the domain must match its real hostname.
o Amount of RAM to be allocated to the guest, in MB. Solaris domains should use 512MB minimum.
o Path to the disk image of the guest. This path is exported as an entire disk to your guest. It is on the xVM control domain and
can be to a physical disk, a flat file, or any device that provides a block device interface; for example, a ZFS volume or a
Solaris Volume Manager volume.
o If the path specified in the preceding bullet does not already exist, the size, in GB, of the virtual disk for your guest.
o You must choose whether to enable graphics support for the domain. Note that paravirtualized Solaris domains do not currently
support a graphical console in this manner.
o URI for the location of the installation software. This can be an NFS path, or the path to a local directory or ISO. Some oper-
ating systems do not yet support ISO installs. Some operating systems require that the install host be fully qualified (for
example, my.nfs.server.com) for the install to work. Examples of acceptable installation paths are:
nfs:my.nfs.server.com:/home/install/test/tree
/export/solarisdvd.iso
After entering required information, installation starts. If you enabled graphics, a Virtual Network Computing (VNC) window opens and
presents the graphical installer. If graphics are not enabled, the text installer displays.
You can connect to the graphical console by finding the correct display with the command:
% virsh vncdisplay dom-name
...and then running:
% vncviewer localhost:d
...where d is the display returned by the preceding virsh vncdisplay command.
Autoconfiguration data (see the --autocf option, below) is presented to the guest as a floppy device. For Solaris, this can be a UFS or
PCFS file system image containing sysidcfg(4) and Jumpstart profile data.
To run virt-install, you must become superuser or assume the Primary Administrator role.
OPTIONS
The following options are supported:
--autocf=location
Specifies location of autoconfiguration data for the guest.
For fully virtualized guests installing from an ISO file or DVD, location specifies the pathname of a disk image to be presented to the
guest as the floppy device fda. The following is the path to a local filename containing a floppy image:
/path/to/guest/autocf.img
This option is ignored for fully virtualized guests installing over a network using PXE. Such a guest will retrieve any autoconfigura-
tion data over the network. For paravirtualized guests, support for this option is guest-specific.
For Solaris paravirtualized guests installing over NFS, this option allows you to specify the NFS pathname to a directory containing a
sysidcfg(4) file along with a Solaris Jumpstart profile. The following is the path to a NFS directory containing Solaris autoconfigura-
tion data:
nfs:netinstall:/export/guests/guest.autocf
-b bridge, --bridge=bridge
Bridge to which to connect the network interface. If you do not specify a bridge, the system attempts to determine the default. This
should be the name of the interface in the control domain through which to route the domain's networking traffic, for example, bge0.
This option is obsolete. Use the -w/--network option, instead.
-c cdrom, --cdrom=cdrom
File to use as a virtual CD-ROM device for fully virtualized guests. This option works with HVM domains and is ignored with paravirtu-
alized domains. It can be path to an ISO image, or to a CD-ROM device. It can also be a URL from which to fetch or access a minimal
boot ISO image. The URLs take the same format as described for the --location argument. If this option is omitted then either the
--location argument must be entered, to specify a location for the kernel and initrd, or the --pxe option used, to install from the
network.
--check-cpu
Check that VCPUs do not exceed physical CPUs and warn if they do.
--connect=URI
Connect to hypervisor at URI.
--cpuset=cpuset
Specify which physical CPUs the guest can use. cpuset is a comma-separated list of numbers, which can be specified in ranges. For exam-
ple:
0,2,3,5 Use processors 0, 2, 3, and 5
1-3,5,6-8 Use processors 1, 2, 3, 5, 6, 7, and 8
-d, --debug
Display debugging information. The debugging information is stored in $HOME/.virtinst/virt-install.log, even if this option is omitted.
In this path, $HOME is the home directory of the user invoking virt-install, such as / or /root.
-f pathname, --file=pathname
Path to the file, disk partition, or logical volume to use as the backing store for the guest's virtual disk. If the path does not
exist, then --file-size option should also be specified, allowing the disk to be created.
-s filesize, --file-size=filesize
Size of the file to create for the guest virtual disk, if the path specified with the --file does not already exist. The filesize is
specified in gigabytes, with fractional numbers allowed. The storage for the file will not be pre-allocated unless the --nonsparse
option is also specified.
-h, --help
Display list of virt-install options.
-k keymap, --keymap=keymap
Request that the virtual console be configured to run with a non-English keyboard layout.
-l location, --location=location
Installation source for paravirtualized guest. Fully virtualized guests must use either --location to specify a kernel and initrd or
the --cdrom option to specify an ISO/CDROM image. The location argument can take the forms, nfs:host:/path, or a file system path in
the control domain, as described above.
-m mac_addr, --mac=mac_addr
Specifies a fixed MAC address for the guest. If this parameter is omitted, or the value random is specified, a suitable address will be
randomly generated. For xVM virtual machines it is required that the first 3 pairs in the MAC address be the sequence 00:16:3e. This
option could be used when performing PXE or NFS-based installations of Solaris guests. This option is obsolete. Use the -w/--network
option, instead.
-n name, --name=name
Name of the new guest virtual machine instance. This must be unique among all guests known to the hypervisor on this machine, including
those not currently active.
--noacpi
Disables Advanced Configuration and Power Interface (ACPI) for fully virtualized guest. Overrides configuration setting stored in sys-
tems specified by --os-type and --os-variant options.
--noapic
Disables Advanced Programmable Interrupt Controller (APIC) for fully virtualized guest. Overrides configuration setting stored in sys-
tems specified by --os-type and --os-variant options.
--noautoconsole
Do not automatically try to connect to the guest console. The default behavior is to launch a VNC client to display the graphical con-
sole, or to run the virsh console command to display the text console. Use of this option disables this behavior.
--nodisks
Request a virtual machine without any local disk storage, typically used for running "Live CD" images or installing to network storage
(iSCSI or NFS root). This disables all interactive prompts for disk setup.
--nographics
Disable all interactive prompts for the guest virtual console. No graphical console will be allocated for the guest. A text-based con-
sole will always be available on the first serial port (or equivalent paravirtualised console device).
--nonsparse
Request creation of a non-sparse file for the guest virtual disk. Note that use of this option causes guest creation to be signifi-
cantly slower than otherwise.
--os-type=os_type
Optimize the guest configuration for a type of operating system. This option attempts to pick the most suitable ACPI and APIC settings,
select optimally supported mouse drivers, and generally accommodate other operating system peculiarities. See "OS Types and OS Vari-
ants", below for a list of acceptable values.
For optimal guest operating system performance, you should specify the --os-type and --os-variant options.
--os-variant=os_variant
The OS variant for fully virtualized guests. See "OS Types and OS Variants", below for a list of acceptable values.
For optimal guest operating system performance, you should specify the --os-type and --os-variant options.
-p, --paravirt
Indicates that guest is paravirtualized. If the host supports both paravirtualization and full virtualization, and neither this parame-
ter nor the --hvm option are specified, this will be prompted for interactively.
--pxe
Use the PXE boot protocol to load the initial ramdisk and kernel for starting the guest installation process. If this option is omit-
ted, then either the --location or --cdrom options must be entered, to specify a location for the kernel and initrd.
-r mem_amount, --ram=mem_amount
Memory to allocate for guest instance, in megabytes.
-s disksize, --file-size=disksize
Size of the disk image (if it does not exist), in gigabytes
--sdl
Use Simple DirectMedia Layer (SDL) for graphics support. This option works with some guest domains, including HVM, but not with
Solaris.
-u UUID, --uuid=UUID
Specifies UUID, as a 32-digit hexadecimal number, for the guest. if no UUID is specified, the system generates a random UUID. If you
enter a UUID, keep in mind that it is intended to be a globally unique value.
-v, --hvm
Specifies that the guest is a Hardware-assisted Virtual Machine (HVM). Requests the use of full virtualization, if both paravirtualiza-
tion and full virtualization are available on the host. This parameter might not be available if connecting to a hypervisor on a
machine without hardware virtualization support.
This guest should be fully virtualized.
--vcpus=vcpus
Number of Virtual (VCPUs) to configure for your guest.
--vnc
Use Virtual Network Computing (VNC) for graphics support. This option works with HVM domains but not with paravirtualized domains.
Unless the --vncport parameter is also provided, the VNC server will run on the first free port number at 5900 or above. The actual VNC
display allocated can be obtained using the vncdisplay subcommand to virsh(1M).
--vncport=vncport
Request a permanent, statically assigned port number for the guest VNC console. Use of this option is discouraged as another guest
might automatically choose to run on the specified port, creating a conflict.
-w property_list, --network=property_list
Describes a virtual interface by means of a list of property-value pairs, each pair separated by a comma. Supported properties are:
bridge=bridge
Bridge to which to connect the virtual interface. If you do not specify a bridge, the system attempts to determine the default.
This should be the name of the interface in the control domain through which to route the domain's networking traffic, for example,
bge0. This property makes the -b/--bridge option obsolete.
mac=mac_addr
Specifies a fixed MAC address for the guest. If this parameter is omitted, or the value RANDOM is specified, a suitable address
will be randomly generated. For Solaris xVM virtual machines it is required that the first three pairs in the MAC address be the
sequence 00:16:3e. This property is required when performing PXE or NFS-based installations of Solaris guests. This property makes
the -m/--mac option obsolete.
capped-bandwidth=bandwidth
Sets bandwidth of this interface. Bandwidth should be specified as an integer with one of the scale suffixes (K, M, or G for Kbps,
Mbps, or Gbps, respectively). Bandwidth will be rounded up to 1.2M, if the input is smaller than that figure.
vlanid=vid
Sets VLAN ID of this interface to vid.
If this option is omitted, a single NIC will be created in the guest. If there is a bridge device in the host with a physical interface
enslaved, this interface will be used for connectivity. This option can be specified multiple times to setup more than one NIC. Do not
mix it with any one of the -b/--bridge and -m/--mac options.
-x extra_args, --extra-args=extra_args
When installing paravirtualized guests, specifies additional arguments to pass to the installer.
