Oracle VM 3 for x86 Essentials Questions and Answers

Question 1

You have configured two virtual machines to use 4 shared iSCSI disks. The first VM was configured correctly but when adding the iSCSI disks to the 2nd VM you don’t see any available disk in the list. Identify two steps that might correct this.

Question 3

You are installing the Solaris 11 OVM template downloaded from Oracle edelivery site. You have previously imported and installed these templates with success on another server. However, when you attempt to start the newly imported virtual machine it through an error indicating that HVM is required for this operation and virtual machine fails to start. There are currently two Para-virtualized VM are already running on the Oracle VM server where the failure is occurring. Which two explanations and situations might remedy this problem?

Options:

A.

Download might be corrupt. Download the template again and attempt the import or use a copy of the template that was previously imported.
