Summary
Instant Virtualization and Full Virtualization or Rapid Return to Production jobs for Red Hat 6.6 or CentOS 6.6 client machines complete, but the resulting VM will not boot up. The boot process will start and then fail. A console message indicates there are no volume groups found on the client machine.
Symptoms
A VM fails to complete the boot process. The Console suggests there is a problem with the logical volume management and the following message displays:
“Setting up Logical Volume Management: No volume groups found”
Resolution
This is a logical volume management issue; the volume group metadata is somehow not being preserved during the virtualization process.
Using the VM’s command shell that is available after the boot process fails, entering the following commands and rebooting will allow the VM to startup properly:
mount -o remount,rw /
vgscan
vgchange -ay
reboot
