devices in the guest configuration and evaluate the Host storage configuration with respect to these
devices and the adapters used to access them.
6.2.8 Do Not Add User Accounts to the hpvmsys Group
The hpvmsys group implements the security model for the VM Host and guests. The hpvmsys
group is automatically added to /etc/group when Integrity VM is installed. Do not add user
accounts to this group.
6.2.9 Do Not Enter Ctrl/B after Starting Guest with Virtual Console
When you use the pc -on command inside the Integrity VM virtual console to start the guest, do
not enter Ctrl/B; this will interrupt the guest boot process. Wait for the guest boot to complete and
the virtual console prompt to return. Then enter Ctrl/B.
6.2.10 How to Stop Guests
To stop a guest, HP recommends that you perform an operating system shutdown from a privileged
account on the guest. If the guest is not responding, use the hpvmstop -g command on the VM
Host. Do not stop a guest by killing the hpvmapp process.
6.2.11 The hpvmconsole pc –cycle Command Occasionally Does not Complete
If the guest hpvmconsole pc –cycle command doesn’t complete and restart the guest, enter
Ctrl/B to interrupt the command and then press Enter to return to the virtual console. Exit the virtual
console by entering the X command. At the VM Host command prompt, enter the following command
to start the guest:
# hpvmstart –P guestname
6.2.12 How to Recover from a Guest Hang
If a guest hangs, attach to the guest's virtual console using the hpvmconsole command, then use
Ctrl/B to enter the virtual console. Enter the tc command to reset the guest. The guest captures a
memory dump of the machine state, which can be used later for offline diagnosis. Do not kill the
guest from the VM Host or use the virtual console to power down a hung guest. Doing so can
corrupt the guest file system.
6.2.13 Using HP Serviceguard to Manage Guests
This section lists release notes specific to using Serviceguard in the Integrity VM environment.
Do not attempt to use guests as Serviceguard packages and guests as Serviceguard nodes at the
same time on the same VM Host system.
You can install HP Serviceguard A.11.16 or 11.17 on the VM Host or on the HP-UX guest. You
can install HP Serviceguard 11.18 on guests running HP-UX 11i v3.
6.2.13.1 Suspend/Resume not Supported with Serviceguard
The hpvmsuspend and hpvmresume commands are not supported with either VMs as
Serviceguard Nodes or VMs as Serviceguard Packages.
6.2.13.2 Serviceguard 11.18 No Longer Supported
Starting with HP Integrity Virtual Machines, Version 4.2, Serviceguard 11.18 is no longer supported
with Integrity VM.
6.2.13.3 Packaging VM Guest with CFS/CVM Backing Stores as Serviceguard Packages
