DESCRIPTION

Use kvmadm to create/edit your KVMs under SMF control

create

    vnc_pw_file
    vcpus
    ram
    time_base
    boot_order
    hpet

kvmadm supports zones. zone properties are according to zonecfg. global properties can be set as "property" : "value" pair, single resources as "resource" : { } hash structure and multiple resources as "resource" : [ { }, ... ] array of hash structures. vnics and zvols must not be added to the zone configuration as kvmadm will add them automatically when setting up the zone.

import

imports a KVM configuration from a file.

delete

start

starts the KVM instance kvm_name

stop

stops the KVM instance kvm_name

restart

restarts the KVM instance kvm_name

show-cmd

prints the KVM invocation command for debug purpose

info

queries information about the running KVM instance from qemu monitor.

type can be one of the following:

all
block
blockstats
chardev
cpus
kvm
network
pci
registers
qtree
usb
version
vnc

monitor

connects to the qemu monitor of the running KVM instance. Sends command to the qemu monitor if provided.

vnc

EXAMPLES

create a KVM instance with the name 'test-kvm'

kvmadm create test-kvm

check the KVM instance properties

kvmadm list test-kvm

list the available KVM instances

svcs system/kvm

copy a KVM instance

kvmadm list test-kvm > test-kvm.json

kvmadm import test-kvm.json

wait 5 minutes before starting the qemu process

"pre_start_cmd" : "/usr/bin/sleep 300"

basic zone setup

"zone" : {
    "zonepath" : "/zones/test-kvm",
    "brand"    : "lipkg",
    "ip-type"  : "exclusive"
}

adding readonly zone access to a vnc password file

            "options" : "[ro,nodevices]"
        }
    ]
}

query the attached block devices of a KVM instance with the name 'test-kvm'

kvmadm info block test-kvm

connect to the qemu monitor of the KVM instance with the name 'test-kvm'

kvmadm monitor test-kvm

set boot drive to d

kvmadm monitor test-kvm boot_set d

forward the vnc socket of the KVM instance with the name 'test-kvm' to the TCP port 5900
