Upgrade the gWLM agent, as described in the VSE Management Software Installation and Update Guide. If you install the current version of Integrity VM without upgrading to gWLM A.02.50 or later, and then attempt to use gWLM within VSE to manage virtual machines, the following error is reported: Error acquiring workload management lock. Look in the the file /var/opt/gwlm/gwlmagent.
3 Creating Virtual Machines This section contains notes about creating and configuring virtual machines on the VM Host system. 3.1 Default Guest Settings for HP-UX, Windows, and Linux Table 3-1 lists the default guest settings for HP-UX, Windows, Linux, and Unknown guests. An Unknown guest is a virtual machine that has not booted with any operating system. When an Unknown guest type boots, the appropriate operating system type is applied to the guest configuration.
3.4 Do Not Create Golden Images of the VM Host for Guest Installation Do not use the VM Host to create golden images to be used for guest OS installations using Ignite-UX. An Integrity system may be used to create a golden image suitable for OS installation on a virtual machine, provided it has all of the VM Host software completely removed.
4 Installing Guests This section describes notes pertaining to installing guest software on the virtual machines. The following sections are included: • “Windows Guests” (page 27) • “HP-UX Guests” (page 28) • “Linux Guests” (page 29) 4.1 Windows Guests This section lists the release notes specific to installing Windows guests. 4.1.
• • • • • After the automatic reboot, Windows controls the console. When you see the SAC> prompt, use Esc-Tab to change the channel to the product key prompt. Stop and start the virtual machine and interrupt the automatic boot sequence. Before the system is allowed to continue, from the virtual console, execute the necessary insert (IN) command to reload the media. After the media is reloaded into the virtual DVD, select the Windows Media install (the first boot option) and allow the system to boot.
4.2.1 HP-UX 11.31 Guests May Fail to Configure More than Two MPT Interfaces If an HP-UX 11.31 system is configured with less than 2112 MB of memory, no more than two MPT interfaces are successfully configured. If more than two interfaces are desired, allocate at least 2.5 GB of memory to the guest. 4.2.2 Patches for HP-UX 11.31 Guests Customers running HP-UX 11.31 guests should install the following patches (or their superseding patches) in each guest running HP-UX 11.
4.3.1 Linux Guest Installation Errors The first time you install the Linux guest management software, the following error may occur: === from /var/log/messages file === Jan 18 22:45:00 lsn0000 kernel: ipmi_si: Error clearing flags: c1 === from "dmesg" command === ipmi_si: Error clearing flags: c1 You can ignore this error message. 4.3.2 Linux Guests with FC Tapes Display Errors MPT errors may appear while booting a Linux guest if FC tapes are attached to it.
# /etc/init.d/tog-pegasus start For information on where to download the Utilization Provider for the Linux guest, see the VSE Management Software Installation and Update Guide. 4.3.5 IPv6 Dynamic Address Resolution is Broken in Linux Linux guests report messages such as printk: 1 message suppressed on a regular basis on the console. To prevent these messages, add the following line to the file/etc/modprobe.conf: alias net-pf-10 off 4.3.
5 Using Integrity VM Commands This section contains notes about the Integrity VM commands. 5.1 Using hpvmmodify -N -s Options Together Causes Guest to Be Inaccessable Using the hpvmmodify -N and -s options together can cause the guest to disappear from the hpvmstatus output and become inaccessible. The guest directory name is erroneously changed, but the guest configuration files still have the original guest names.
displays the device, and the hpvmmodify command does not retry the device removal, but the guest operating system sees the device as available. To remove the device, restart the guest. 5.7 Missing uuid or .vmid Files If you use Integrity VM commands while guests are being removed, you may receive errors about missing uuid or .vmid files. Enter the command after the guest removal has completed. 5.
Exporting these environment variables allows you to display the manpage content from a Linux guest console. Some minor differences in the appearance of the manpages as displayed on HP-UX and as displayed on Linux are expected. 5.
6 Guest Administration This chapter contains information about managing Integrity VM guests. 6.1 Administrator Account Names This version of Integrity VM lifts the restriction that the virtual console administrator account names must be the same as the guest name. As a result, the virtual console administrator name can be any valid HP-UX login name.
-d /var/opt/hpvm/guests/testme \ testme1 # useradd -r no -g users -s /opt/hpvm/bin/hpvmconsole \ -c "Console access to guest 'testme'" \> -d /var/opt/hpvm/guests/testme \ testme2 # useradd -r no -g users -s /opt/hpvm/bin/hpvmconsole \ -c "Console access to guest 'testme'" \ -d /var/opt/hpvm/guests/testme \ testme3 The following command creates the virtual machine named testme: # hpvmcreate -P testme -u testme1:admin -u testme2 -u testme3:oper At this point, users testme2 and testme3 both have oper level a
6.7 Restoring the NVRAM for Windows Guests When a guest has been terminated unexpectedly due to a panic or another critical condition, the guest's boot settings (which are stored in a per-guest NVRAM file on the VM Host) can become corrupted. This can cause problems with subsequent reboots of that guest. To correct the problem, copy the file /opt/hpvm/guest-images/common/nvram to /var/opt/hpvm/guests/vm_name/nvram on the VM Host system.
6.11.1 Required HP Serviceguard Patches To use Serviceguard to manage HP-UX guests, make sure the required patches are installed. For more information, see Section 2.1.6 (page 18). 6.11.2 Reenter Command to Start Packages The procedure for configuring and starting guest packages includes the cmrunpkg command. This command does not always work the first time you enter it. If the command does not start the package, re-enter the command. 6.11.
HPVMNETINTVL=n Where n is an integer between 1 and 10 that specifies the number of seconds. The default value is 5. That is, if the HPVMNETINTVL tunable is not set in the file, the value is 5 seconds. For Serviceguard in Integrity VM configurations, the recommended value is 2.
7 Networking Information This section contains notes about configuring networks for virtual machines. 7.1 Vswitches Are Always in SHARED Mode The hpvmnet command displays the status of the vswitches, including the mode. The vswitches are always in SHARED mode. No other modes are supported at this time. 7.
7.7 Do Not Turn on TSO on the VM Host and on HP-UX Guests TCP Segmentation Offload (TSO) is turned off by default in HP-UX. HP recommends that you leave it turned off on both the VM Host system and on HP-UX guests. This applies to both the virtual network interface cards in the guest and any physical network interface cards in the VM Host that are used by vswitches. When TSO is enabled, guest networks are interrupted.
When you restart a vswitch, it is not necessary to restart the guests using the vswitch. 7.
8 Storage Information This section contains information about storage devices used as backing stores for guest virtual devices. 8.1 DMP Files Not Supported as Backing Stores Veritas VxVM DMP device files (files under /dev/vx/rdmp/) is not supported by Symantec for whole disk backing stores for virtual machines. 8.2 Using Database Management Products on Virtual Machines For optimal performance with storage intensive applications such as Oracle®, HP strongly recommends using whole disk backing stores.
8.8 Using sam on Guest Cannot Initialize Disk When you create a file system using the sam command on an HP-UX guest, do not initialize the disk. This option returns an error and the file system is not created. 8.9 Extending a Logical Volume Backing Store Corrupts the Guest On the VM Host, do not extend a logical volume (LVM or VxVM) used as a backing store for a guest root disk.
9 Migrating Virtual Machines This section contains information about migrating virtual machines. 9.1 Do Not Migrate Distributed Guests Guests that are configured as Serviceguard packages cannot be migrated. 9.2 Collect CapAd Data before Migrating If you migrate a virtual machine that is being managed by VSE, use Capacity Advisor to collect utilization data before you migrate the virtual machine. Otherwise, the utilization information for the VM Host prior to the migration is lost. 9.
10 Error Logging This section contains information about the way Integrity VM logs messages. 10.1 Guest Log Can Grow Unbounded The guest monitor log file (/var/opt/hpvm/guests/vm_name/log) records guest start and stop information. These log files can grow very large. Use the hpvmconsole command rec -rotate to close the current log file, rename it, and open a new one. 10.2 Log Messages Written to Old Log File Log messages might be written to the command.log.old file instead of the command.log file.
