How to recreate guest configuration files after updating Integrity VM V4.0 VM Host to Integrity VM V4.1

Contents

Abstract

This article explains how to recover Integrity Virtual Machines guest configuration after upgrading from version 4.0 to 4.1.

Background

After updating Integrity VM Host from version 4.0 to version 4.1, the guest configuration files are moved to /var/opt/hpvm_backup directory. The hpvmstatus command will show no Guest information on execution:

# hpvmstatus
hpvmstatus: No guest information is available.
hpvmstatus: Unable to continue.

This is consistent with the following statement on the HPVM 4.1 Administration guide:

The new configuration files are not compatible with those of previous versions of Integrity VM. Therefore, if you are upgrading to the current version, the guest configuration files (except the /ISO-Images/ directory) are saved to the /var/opt/hpvm_backup directory.

Procedure

The supported method to recover the VM guest configuration, is to recreate the guests using the hpvmcreate command. The guest configuration files are not automatically exported to HP Integrity VM 4.1 configuration directory.

New configuration files can be created with the information available in the backup files using the -F option of the hpvmmodify command.

# hpvmmodify -P <guest> -F

This option will suppresses all resource conflict checks and associated warnings messages (force mode). In this context, will take the old version configuration files and update only the Integrity Virtual Machine Release data of the configuration files.

Example:

# hpvmstatus -P rx7620c
hpvmstatus: No guest information is available.
hpvmstatus: Unable to continue.
# hpvmmodify -P rx7620c -F
# hpvmstatus -P rx7620c
