(*) Before removing virtual devices with the hpvmmodify command, make sure that the guest operating system is
no longer directing I/O to the device. Dismount the device if it is mounted. If you attempt to remove a device that
has I/O in progress, the hpvmmodify command incorrectly removes the device from the guest configuration file. The
hpvmstatus command no longer displays the device, and the hpvmmodify command does not retry the device
removal, but the guest operating system sees the device as available. Reboot the guest to remove the device.
(**) When you use –m option you need to specify hardware-address. (If you want to modify hardware-address use
–d to delete it and then –a to add with the new hardware-address)
(***) VM cannot detect all potential backing store conflicts. Care with: multiple path to the same disk, overlapping
physical storage allocated for different backing store types… It can result in data corruption.
Example:
# hpvmmodify –P vmguest1 –a disk:scsi:0,1,2:disk:/dev/rdsk/cXtYdZ
-a disk:scsi::lv:/dev/vgXX/rlvolY
-a disk:scsi:0,1,1:file:/guestfiles/diskfile
-a dvd:scsi::disk:/dev/rdsk/cXtYdZ
-a dvd:scsi::null:/ISO-directory
-a tape:scsi::attach:/dev/rscsi/cXtYdZ
hpvmnet
A virtual machine accesses its network through a virtual LAN device connected to a virtual
network switch (vswitch). The virtual network switch is connected in turn to a single physical
network interface (NIC) on the VM Host. The hpvmnet command is used to create and manage
vswitches.
A vswitch works like an actual network switch. It accepts outbound network traffic from all
guests configured to use it and transmits the traffic over the physical interface. It accepts inbound
network traffic for all guests configured to use it and directs the traffic to the appropriate guest.
A virtual switch can be shared by multiple virtual machines or dedicated to a single virtual
machine. It can be associated with at most one physical network interface. The VM Host's
physical network interface must be attached to a network with connectivity to the desired
subnets. The network interface may optionally be configured in the VM Host with an IP address
or multiple IP alias addresses, but this is only necessary if the VM Host shares the interface with
