Oracle VM 2 for x86 Essentials Set 2

1.

When vitalizing a cluster of Windows 2003 servers on Oracle VM, which virtualization technique
should be used?

Use PV with Microsoft's Windows 2003 64-bit with a paravirtualized kernel Use HVM with a standard distribution of Windows 2003 and PV drivers. Use emulation with the IOEMU drivers for better I/O performance. Oracle VM does not support Windows 2003 Server. Use VirtualBox instead. Oracle VM does not support Windows 2003 Server. Use Containers instead.

2.

A customer is running an existing server farm of open source Xen servers running the same version of Xen as
Oracle VM 2.2. The customer would like to manage these servers with Oracle VM. What is the best reason that
this will not be possible?

Oracle VM's Xen implementation uses a different disk format for virtual machines than open source
Xen, so live migration of virtual machines will not work between the existing Xen implementation and
Oracle VM. Oracle VM employs a layer of technology on top of Xen that enables remote management throughOracle VM Manager or Oracle Enterprise Manager. The existing Xen servers are incapable of communicating in this manner. Oracle VM uses a forked Xen distribution, so although the version numbers are the same, the behaviorof the virtual machines at run time will be different. Oracle VM uses a highly proprietary protocol format for Live Migration that enablesstrongencryption. Standard Xen servers will not be able to live migrate to the Oracle VM servers, or vice versa.

3.

What two attributes of a virtual machine are not available on the Oracle VM Manager Home screen when the virtual machine is currently powered down?

Memory Size Server Name VNC Port Server Pool Name Owner

4.

Which two statements describe Oracle Validated Configurations?

Oracle Validated Configurations provide testing of a "complete component stack"
andrecommendations on versions, settings, and fixes for the particular stack (software, hardware, and
storage) based on running workloads in Oracle's or a partner's test lab. Oracle Validated Configurations are a mandatory step in Oracle's certification process. Oracle Validated Configurations are working samples of hardware and software configurations in anOracle VM environment. All validated configurations must be run in Oracle's lab. Oracle Validated Configurations are potential examples of hardware and softwareconfigurationswhose specifications are validated by Oracle.

5.

Which three attributes of an existing virtual disk can be changed using Oracle VM Manager?

Virtual Disk N Virtual Disk Size Hard Drive Type QoS Enabled Priority Class

6.

What command(s) will create a new 10 GB virtual disk named Apps, and attach it to a virtual machine
named Test?

sd new -d 10240 -n Apps
vm sd attach -n Test -d Apps

sd new -d 10240 -n Appssd reg -n Apps vm sd attach -n Test -d Apps

vm disk add -n Test -d Apps -S 10240

vm sd attach -n Test -d Apps -S 10240

vm disk add -n Test -d Apps -S 10240vm sd attach -n Test -d Apps

7.

When a domain is live migrated, what resources are migrated between the source and target servers?

First the VM files are migrated between the servers, then the memory, then the CPU registers. First the VM files are migrated between the servers, then the memory. First the memory is migrated between the servers, and then the CPU registers. Only memory is migrated.

8.

There is an issue booting into a virtual machine. The log files show that there is an issue during the Linux boot process of the guest. What two methods will best help determine the problem?

Use xm console to attach to the guest while it is booting and look for the specific error. Run xm dmesg to see hardware errors in the guest. Run xm info to see the list of devices being attached to the virtual machine. xm block-attach the disk to another virtual machine to inspect the file system and check moduleloading issues.

9.

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?

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

10.

What two configuration files are associated with an OCFS2 cluster?

/etc/ocfs2/cluster.conf /etc/sysconfig/ocfs2 /etc/sysconfig/cluster.conf /etc/sysconfig/o2cb
