Virtual Machine/VM Host/VM Guest.

Hi All,

I am slightly confused b/e the following terminology:-

o Difference between Virtual Machine/VM Host/VM Guest.
o Could you also give me an example of using hpvmcreate specifing Virtual machine name,Operating system type,Virtual CPUs (vCPUs),CPU entitlement,Memory,Virtual devices,Virtual machine label,Dynamic memory which and when necessary [In a Real Time Environment]

I have it...

# hpvmcreate -P HPVM1 -O HP-UX -c 4 -r 4G

I have ommited -e.. thinking that it would take the default 10% and in due course of time If needed will use hmvmmodify to change it.I do not know how to Create Virtual Network Devices.

If you can provide the command with a sample o/p I would be very Thankful.

I have also gone through the below link:-

Difference between Virtual Machine/VM Host/VM Guest.

Virtual Machine:
The virtual servr you "build" using the VM software
VM Host:
The physical server and OS that the VM softare is installed on, and which will contain the Virtual Machines
VM Guest:
The Operating System you install on to your VM

well creating the virtual network devices is documented in the chapter Creating Virtual Networks (Chapter 8) of the manual you have gone through.

As for the command line examples, there are many in that manual, and also take a look at examples in the hpvmcreate man page:
man hpvmcreate

I will add on to Melvyn's response that there is nothing that can replace reading the admin guides so you completely understand how this works.

You already have 90% of a typical create command posted.
Create a 4 cpu 4GB guest called HPVM1
# hpvmcreate -P HPVM1 -O HP-UX -c 4 -r 4G

Need to add some devices.
Create a virtual switch on the Vhost with hpvmnet.

Decide on types of backing storage, raw, lv, or file.

Typical addition would be.

# hpvmcreate -P HPVM1 -O HP-UX -c 4 -r 4G -a disk:scsi::lv:/dev/vg1/rhpvm1_disk1

or

-a network:lan::vswitch:vmsw1

or
to create a dynamic dvd allowing the selection of files in a directory
-a dvd:scsi::null:/directory

or to hard assign a DVD device

-a dvd:scsi::disk:/dev/rdsk/c0t0d0

etc...

etc...

etc...
