HP Integrity Virtual Machines Version 4.2 Release Notes

> -d /var/opt/hpvm/guests/testme \
> testme4
'/var/opt/hpvm/guests/testme' is not a valid directory
To enter the command correctly, include the entire directory path. For example:
# useradd -r no -g users -s /opt/hpvm/bin/hpvmconsole \
> -c "Console access to guest 'testme'" \
> -d /var/opt/hpvm/guests/testme/. \
> testme4
# hpvmmodify -P testme -u testme4
# passwd testme4
Note the addition of the slash and period (/.) to the end of the argument to the -d option, which
ensures there is no confusion with HP-UX shared home directories.
6.7 Reconfiguring VM Host CPUs
Do not reduce the physical CPU count below the virtual CPU (vCPU) count of any guest. No
running guest should be allocated more vCPUs than the VM Host system has physical processors.
6.8 Monitor Logs Might Report Warnings
On rare occasions, the monitor log might report warnings such as the following:
Warning: VCPUn not scheduled for x ms, command 0x0.
Warning: No recorder entry on VCPUn for x ms.
These warnings are generally harmless, but might indicate performance problems with your
virtual machines, such as system or I/O overloads.
6.9 Warning Message Might Appear When Configuring or Starting Guests
When configuring or starting Integrity VM guests, the following warning message might be
displayed if storage associated with the guest appears to be performing very poorly.
hpvmcreate: WARNING (host): Device /dev/rdsk/c6t9d0 took 32 seconds to open.
If this message is appearing when configuring or starting a guest, Integrity VM does not support
running that guest with the devices specified in this message. Replace the devices with different
devices in the guest configuration and evaluate the Host storage configuration with respect to
these devices and the adapters used to access them.
6.10 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.
6.11 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.
6.12 HP-UX 11i v3 Guests Might Panic with a NaT_hndler: kernel NaT
Consumption Fault
Under certain situations, an HP-UX 11i v3 guest might panic with a NaT_hndler: kernel
NaT Consumption fault when using Logical Volume Manager (LVM) software.
To avoid this situation, install the BaseLVM (B.11.31.0712) software from the HP-UX 11i v3 0712
AR media.
