xend(1M) System Administration Commands xend(1M)NAMExend - xVM control daemon
SYNOPSIS
/usr/lib/xend
DESCRIPTION
The xend daemon provides control of the Solaris xVM domains on a sys‐
tem. Its administrative interface is xm(1M).
Service Management Facility Support
The xend service is managed by the service management facility, smf(5),
under the service identifier:
svc:/system/xvm/xend:default
Administrative actions on this service, such as enabling, disabling, or
requesting restart, can be performed using svcadm(1M). The service's
status can be queried using the svcs(1) command.
xend Properties
The xend service instance has the properties listed below. These prop‐
erties are administered by means of svccfg(1M) and svcadm(1M).
config/default-nic
Specifies the default network interface used for guest domain net‐
working. By default, the empty string is specified, in which case
the first interface listed in the output of dladm(1M) show-link is
used. If you need to use a different interface, for example, bge0,
you should change this property appropriately.
config/dom0-cpus
The number of physical CPUs to be used for the virtual CPUs of the
control domain (dom0). The default of 0 implies that each virtual
CPU will be placed on its own physical CPU where possible. Note
that physical CPUs can still be shared between dom0 and other
domains unless they are configured not to do so.
config/dom0-min-mem
The minimum amount of memory guaranteed to the control domain
(dom0). The default is 196 (MB). Using the xVM milestone service,
svc:/milestone/xvm, or the Hypervisor Visual Panel will change this
value to whichever is lower, half of system memory or 2048 (MB).
config/enable-dump
Controls whether a domain core dump should be created if a domain
crashes. Dumps are generated in /var/xen/dump and can be processed
with mdb(1). The default is true.
config/vncpasswd
Sets the password required by any client connecting to a VNC ses‐
sion for a guest domain. Defaults to "" (no password). VNC password
authentication is not secure and should not be used for securing
guest domain consoles.
config/vnc-listen
Address to listen on for VNC connections. By default this is
127.0.0.1, which has a special meaning: only users or processes
with the PRIV_VIRT_MANAGE privilege are allowed to connect, and
they must be logged on locally. If you set this to any other value,
then anyone will be able to connect to VNC sessions, regardless of
authorization.
config/xend-relocation-address
Address that xend listens on for relocation requests. If blank or
not present, all interfaces are used. The default is 127.0.0.1.
config/xend-relocation-hosts-allow
A space-separated list of regular expressions. If the host name of
a system matches any one of the given regular expressions, it is
allowed to connect and interact with the relocation server, if the
server has been enabled by the xend-relocation-server property. The
default is ^localhost$.
config/xend-relocation-server
Controls whether the xend relocation server (for live migration)
should listen for relocation requests on TCP port 8002. The default
is true.
config/xend-unix-server
Controls whether the legacy HTTP server interface should be pro‐
vided on the local machine. The default is true.
EXAMPLES
Example 1 Modifying an Existing Property
Use the following sequence of commands to modify an existing xend prop‐
erty.
# svccfg -s svc:/system/xvm/xend:default listprop
# svccfg -s svc:/system/xvm/xend:default setprop config/dom0-cpus = 1
# svcadm refresh svc:/system/xvm/xend:default
Example 2 Enabling Live Migration
By default, xend listens only on the loopback address for requests from
the localhost. If you want to allow other machines to live migrate to
the local machine, you need to configure xend appropriately. For exam‐
ple:
# svccfg -s svc:system/xvm/xend
svc:/system/xvm/xend> setprop config/xend-relocation-address = ""
svc:/system/xvm/xend> setprop config/xend-relocation-hosts-allow = \
"^flax$ ^localhost$"
svc:/system/xvm/xend> end
# svcadm refresh svc:system/xvm/xend:default && \
svcadm restart svc:system/xvm/xend:default
