Changes to I/O Configuration Are Not Displayed in VM Manager

When you change your I/O configuration outside VM Manager (such as adding or removing devices through the command line or other tools), the updated configuration is not shown until the display is refreshed.

Workaround

The display is automatically refreshed at regular intervals. To refresh the display manually, click the Refresh Data link.

to refresh the I/O device information, use the Refresh link in the Set Network and Set Storage screens of the Create Virtual Machine wizard.

Incomplete Network or Storage Information from Virtual Machines

Incomplete network or storage information is available from virtual machines if the VM Provider is not running on all of the started virtual machines and on the VM Host.

Workaround

Enter the following command on each VM and look for the response “HPVMProviderModule OK”:

cimprovider -ls

If the information on the VM Manager screens is incomplete, it could be a result of VM Manager's asynchronous discovery, which does not wait for every result before drawing a page. If the expected information is not displayed, click the Refresh Data link.

Slow Response Time on Systems with Many Heavily Active Virtual Machines

The amount of CPU reserved for non-virtual machine processes running on the VM Host is controlled by two tunable parameters in the /etc/rc.config.d/hpvmconf file. These parameters are SVRCPURESPCT and SVRCPUALLOWPCT. Both parameters are interpreted as percentages of a single CPU and are initially set to 20.

In practice, on a multiprocessor VM Host, the server percentage is split equally across all processors on the host, with the percentage per processor rounded up to the nearest whole number. Thus, a 20% value for a 1-way host reserves 20% of that processor for host processes. On a 2-way host, 10% of each processor is reserved. On a 4-way host, 5% of each processor is reserved. On an 8-way host, 3% of each processor is reserved (due to rounding). On a 16-way host, 2% of each processor is reserved (again, because of rounding).

Workaround

To give more processor resource to management applications running on the VM Host, increase both of these parameters to the same new value. After these parameters are changed, stop and restart Integrity VM for the changes to take effect.

Virtual Machines Not Identified Correctly

Virtual machines might not be correctly identified as such if the VM Provider is not running on the virtual machine or if the VM Host is not included in HP SIM discovery. In either of these cases, the virtual machines are color-coded the same as standalone servers, and they have no View: VM link in the System View. However, the model string still identifies them as HP Integrity Virtual Machines.

Workaround

  1. To determine if the VM Provider is running on a virtual machine, enter the following command on the virtual machine and look for the response “HPVMProviderModule OK”:

    # cimprovider -ls

    If you do not see the expected response, install the VM Provider on the virtual machine. For installation instructions, see the VSE Management Software Installation and Update Guide Version A.03.00.01 (“Installing VSE Agent Software on Managed Systems”).

  2. Include both the VM Host and the individual virtual machines in the HP SIM discovery list. This enables HP SIM and the VSE Management Software to properly associate the virtual machine and the VM Host to one another and enables management using HP Integrity Virtual Machines Manager.

Versions of Integrity Virtual Machines, VMProvider, and VMGuestLib Must Be Compatible

If VMProvider, VMGuestLib, and HP Integrity Virtual Machines are already installed, upgrades of any of these three products require upgrades of the others so that all versions are compatible and all products function correctly.

Workaround

It is generally a good idea to upgrade all three products at the same time. However:

  • If HP Integrity Virtual Machines is upgraded on the VM Host, VMProvider and VMGuestLib running on a virtual machine need not be upgraded; however, if they are not, some features might not be available in VM Manager.

  • If VMProvider is upgraded on a VM guest, the VMGuestLib must also be upgraded and vice versa, and neither can be upgraded to a version higher than that of HP Integrity Virtual Machines running on the VM Host.
