HP Integrity Virtual Machines Manager 4.1 Software: Release Notes

Limitations and restrictions
This section describes limitations or restrictions in this release of VM Manager. For this release,
there are no known limitations or restrictions.
Major issues
This section describes known issues that significantly affect functionality or usability of VM
Manager.
Online migration of a VM fails if modifications were made to the VM that still require
a reboot
Applies to usage with: Both Insight Dynamics and HP SMH Standalone
When you use VM Manager to modify a virtual machine, some changes might be held pending
until the virtual machine is rebooted (for example, changes to memory, vCPU count, and I/O
devices). If you try to migrate the virtual machine online while it is in this pending state, the
migration fails.
Workaround 1 Reboot the virtual machine to apply the pending changes, then retry the migrate
operation.
Workaround 2 Discard the pending memory entitlement changes by executing the following
command on the VM Host and then retry the online migration:
/opt/hpvm/bin/hpvmmodify -U -P vm-name
Minor issues
This section describes known issues that do not have a significant impact on functionality or
usability of VM Manager. Suggestions for working around these issues are included.
VM Manager screens might incorrectly identify or omit USB backing devices
Applies to usage with: Both Insight Dynamics and HP SMH Standalone
Integrity VM 4.x allows a USB DVD or CD drive to be used as the backing devices for a virtual
DVD or CD in a virtual machine. However, in the HP-UX 11i v3 September 2008 Operating
Environment Update Release (OEUR) and earlier, the drivers for the USB devices are not
completely integrated into the HP-UX 11i v3 agile mass storage stack. They have neither a
persistent device special file nor a LUN hardware path. In addition, they have an ioscan
description that might not correctly indicate the type of device. For example, ioscan might
report "USB SCSI Stack Adaptor" as the description of a USB DVD drive. If a USB device is used
as the backing device for a virtual DVD, it appears on the VM Host Storage or VM Proper ties
Storage tab with the same description given it by ioscan. Although that description might not
indicate that the device is a DVD drive, the device is tagged with a DVD icon to indicate that it
is a CD or DVD drive.
Additionally, because the device has no agile address, in the Add Storage Device dialog used
with the Modify→Add Storage Device menu item and in the Create Virtual Machine wizard,
a USB DVD or CD drive is displayed in the list of potential backing devices only when the "legacy
addressing" radio button is selected. It does not appear when the "agile addressing" radio button
is selected (the default value on first entry to the dialog).
Workaround You can remove this limitation by installing new USB drivers and additional
patches available at the following IT Resource Center (ITRC) website:
