To create guests, use the hpvmcreate command, specifying
the guest characteristics using the command options shown in Table 4–1.
Table 4-1 Options to the hpvmcreate Command
| Guest Characteristic | Command Option |
| Guest name | -P vm_name |
| Operating system | -O os_type |
| Virtual CPUs | -c number_vcpus |
| CPU entitlement | -e percent-E cycles |
| Memory | -r amount |
| Virtual network devices | -a rsrc |
| MAC address | -a rsrc |
| Boot path | -a rsrc |
| Startup behavior | -B start_attr |
| Admin account name | -u usergroup:[kind]-g group:[kind] |
| Application disks | -a rsrc |
Note that these items of information are almost equivalent to the information
in the guest planning worksheet provided in “Allocating
Resources to Guests” in Chapter 2. You can use the information
you recorded in your guest planning chart to create each guest.
Specifying Virtual Devices |
 |
To allocate virtual network devices and virtual storage devices to guests,
you use the -a option with the rsrc argument.
The rsrc argument supplies all the information
that the VM Host needs to allocate the device to the guest.
Use the -a option to the hpvmcreate command
to specify both virtual storage devices and virtual network devices. If the
required resources are not available on the current VM Host system, the guest
is created and warning messages describe the resources that are not available.
This allows you to create guests for future system configurations.
For storage devices, enter the resource specification in the following
format:
device-type:adapter-type:[hardware-address]:storage-type:device
|
The device information contains the guest virtual device information
(device-type:adapter-type:[hardware-address]) and the physical device information
(storage-type:device),
separated by a colon (:).
The guest virtual device information consists of the following fields,
separated by colons:
device-type (virtual device
type): disk or dvd
adapter-type (virtual device
adapter type): scsi
[hardware address] (optional).
If you do not specify the virtual device hardware address, it will be generated
for you (recommended). If specified, the hardware address is formatted as bus:device:target.
SCSI target number (target)
storage-type:device
Table 4–2 lists the physical storage types and associated device
specifications. You can specify the following storage types
Table 4-2 Physical Storage Types
| Storage Type | Device | Example |
| disk | Disk or DVD | /dev/rdsk/c4t3d2 |
| lv | LVM or VxVM character logical device file | /dev/vg01/rlv0l2 |
| file | Locally-mounted, nonHFS file | /guestfiles/diskfile |
| null | VxFS directory containing ISO files | /docs |
For examples of using the hpvmcreate command to create
guests and allocate various virtual devices, see “Example
Guest Creation.”
You can also use the rsrc resource
specification to associate a guest virtual network device with a virtual network
switch (vswitch). Before you can associate the virtual network device to a
virtual switch, you must create the vswitch using the hpvmnet command.
The format of the rsrc for network devices
is:
network:lan:[hardware-address]:vswitch:vswitch-name
|
The guest virtual network device information consists of the following
fields, separated by colons:
[hardware-address] (optional),
formatted as bus,device,mac-addr. If you do not specify the hardware address,
or a portion of it, the information is generated for you (recommended). The
hardware address consists of the following information:
bus (virtual network device
PCI bus number)
device (virtual network
device PCI slot number)
mac-addr (the virtual network
device MAC address) in either of the following formats: 0xaabbcc001122 or
aa-bb-cc-00-11-22. The MAC address that you enter is checked to make sure
it does not conflict with any of the VM Host’s physical network adapter
MAC addresses and to make sure that the “locally-administered”
bit is set, and that the “multicast” and “broadcast”
bits are clear.
vswitch
The virtual switch information is formatted as vswitch:vswitch-name (where vswitch-name is
the name assigned to the virtual network switch when you create it using the hpvmnet command)
Cloning Guests |
|
Once you have created a guest, you can easily create an identical guest
by using the hpvmclone command. Like hpvmcreate and hpvmmodify,
the hpvmclone command accepts the -a option
for specifying virtual device mapping. This allows you to create new guests
with similar characteristics but different virtual resources. For more information
about using the hpvmclone command, refer to hpvmclone(1M) .
Example Guest Creation |
|
The example guests described in Chapter 2 can be created as described
in this section. To create the first guest in the example configuration (compass1),
enter the following command:
# hpvmcreate -Pcompass1 -c1 -r1G \
-a network:lan::vswitch:clan1\
-a network:lan::vswitch:clan2\
-a network:lan:0,1:vswitch:localnet \
-a disk:scsi::lv:/dev/vg01/rlv022\
-a dvd:scsi:0,0,1:null:/dev
# |
The guest compass1 has one virtual CPU, 1 GB of memory,
and 5% entitlement (the default). It has network access using both vswitches clan1 and clan2,
and accesses the logical volume named rlv022.
To create the second guest (compass2), enter the
following command:
# hpvmcreate -Pcompass2 -c2 -r3G -e50 -B manual\
-a disk:scsi:1,0,2:disk:/dev/vg01/rlv023
# |
The guest compass2 has one virtual CPU, 3 GB of memory,
and 50% entitlement. It is allocated access to the disk device associated
with /dev/vg01/rlv023. Network access will be through the
local network only.
To create the third guest (compass3), enter the following
command:
# hpvmcreate -Pcompass3 -c1 -r2G \
-a disk:scsi::disk:/dev/vg01/rlv023 \
-a network:lan::vswitch:clan1
HPVM guest compass3 configuration problems:
Warning 1: Insufficient free memory for guest.
These problems may prevent HPVM guest compass3 from booting.
hpvmcreate: The creation process is continuing.
# |
Note that compass3 was created even though memory
resources are insufficient to run this guest on the current VM Host. You can
modify the characteristic of a guest by using the hpvmmodify command,
as described in “Changing Guest
Configurations” in Chapter 5.
If problems exist on the VM Host system when you boot the guest, the
guest is not allowed to boot.
You can view information about the guest configuration using the hpvmstatus command:
# hpvmstatus
[Virtual Machines]
Virtual Machine Name VM # OS Type State # vCPUs # Devs # Nets Memory
==================== ===== ======= ======== ======= ====== ====== ===========
