• B.A blkfront driver is used in dom0, and a blkbck driver is used in the guest.
• C.Native drivers are used in both dom0 and the guest.

What is the correct sequence for importing a P2V image?

• A.1. Insert Oracle VM Server disk into server to be converted.2. Boot server and type linux p2v at the boot prompt.3. Configure settings for virtual machine import.4. In Oracle
  VMManager, go to the Virtual Machine Images page and click on Import.5. Enter information on the virtual machine, then give the IP address of the server to be imported.
• B.1. InsertOracle VM Manager disk into server to be converted.2. Boot server and type linux p2v at the boot prompt.3. Configure settings for virtual machine import.4. Wait for the conversion to finish, then go to the Oracle VM Manager.5. Enter information on thevirtual machine, then give the IP address of the server to be imported.
• C.1. Insert Oracle VM Server disk into server to be converted.2. Boot server and type linux p2v at the boot prompt.3. Configure settings for virtual machine import.4. Wait for the conversion to finish, then open a browser to the IP address of the server being converted.5.
  On the page presented, select the server pool to be targeted.
• D.1. Insert Oracle VM Manager disk into server to be converted.2. Boot server and type linux p2v at the bootprompt.3. Configure settings for virtual machine import.4. In Oracle VM
  Manager, go to the Virtual Machine Images page and click on Import.5. Enter information on the virtual machine, then give the IP address of the server to be imported

Networking is not working for several guests on a particular host. Which two commands can help troubleshoot the networking?

• A.ifconfig -a will show a list of all network interfaces and their current status, which will help determine which bridge is having problems.
• B.brctl show will show the status of each bridge, and which VIFs are connected to it. This canthen be used to determine which bridge is having problems.
• C.xm list -1 will show all of the network interfaces for all of the virtual machines, which can be used to see which bridge is having problems.
• D.System-config-network will list the virtual interfaces, which can be inspected to see which are having problems.
• E.config_network.py -l will show which network interfaces are in use, and which are having problems.

After configuring a DRS policy in your Oracle VM environment you decide to test it by forcing one of your guest to 100% CPU utilization. After 5 minutes nothing happens. List two possible reasons for this.

• A.You have not told Oracle VM manager to start gathering performance matrix which is related to compare for the sample against.
• B.You should not publish the policy to all over the Oracle VM servers yet so they don't know what the thresholds are.
• C.You left the monitoring period at default 10 minutes and Oracle VM has not gathered the second performance samples.
• D.The DRS policy updated is in direct conflict with the default DPM policy. You should correct this before continuing.
• E.Even though the guest CPU utilization is above the DRSCPU threshold it was not enough to bring the VM CPU utilization above the threshold.

A server with 16GB of RAM is only showing 8GB available after boot, but before running any virtual machines. What method will best find the issue?

• A.Use dmesg to see messages logged duringthe booting of dom0.
• B.Look in /var/log/xen/xend-debug.log for hardware-related messages.
• C.Look in /var/log/xen/xend.log for hardware-related messages.
• D.Use xm dmesg to see messages logged during the booting of the Xen hypervisor.
