HP Integrity Virtual Machines 4.3: Installation, Configuration, Administration

NOTE: If the guest is configured with a number of VLAN devices, but it does not have sufficient
memory, some of the devices might be missing after the guest is booted. To resolve this issue,
increase the size of the guest memory with the hpvmmodify -r command.
If you configure an HP-UX guest and an OpenVMS guest with the same vswitch, the network
communication between these guests fail. This problem will be fixed in a future version of
OpenVMS.
To workaround this problem, configure the HP-UX guest and the OpenVMS guest with different
vswitches.
For more information about creating and managing VLANs on virtual switches, see Section 7.4
(page 132).
3.2.7.2 Creating Virtual Storage Devices
When you create a virtual machine, you specify the virtual storage devices that the virtual machine
uses. Virtual storage devices are backed by physical devices on the VM Host system (backing
stores). The VM Host system must have sufficient physical storage for the VM Host and for all
of the virtual machines.
Use the -a option to create and allocate the virtual device to the virtual machine. For example:
# hpvmcreate -a VM-guest-storage-specification:VM-Host-storage-specification
where:
• VM-guest-storage-specification defines where and what storage is seen in the
virtual machine. This is formatted as:
device:adapter-type:hardware-address:
You can specify one of the following devices:
— disk
— dvd
— tape
— changer
— burner
— hba
NOTE: DVD burners are not currently supported on OpenVMS guests.
• adapter-type can be scsi or avio_stor on an HP-UX guest.
• hardware-address or pcibus, pcislot,scsitgt (optional) specifies the virtual device PCI
bus number, PCI slot number, and SCSI target number. If you do not specify this information,
it is generated automatically. HP recommends that you allow the hardware address to be
generated automatically. To omit the hardware address, use the following format (including
two colons):
device:adapter-type::VM-Host-storage-specification
• VM-Host-storage-specification defines where and how the virtual machine storage
is supplied on the VM Host. Specify it using the following format:
storage:location
Where storage is one of the following:
— disk
— lv
— file
