Ensure that the Oracle VM Manager is always available by installing Oracle Clusterware.

Turn on High Availability Mode in the server pool.

Assign a virtual IP address to the server pool.

Turn on HA in all virtual machines that will be restarted.

Ensure all servers in the pool have identicalCPU and memory.

You left the monitoring period at default 10 minutes and Oracle VM has not gathered the second performance samples.

You have not told Oracle VM manager to start gathering performance matrix which is related to compare for the sample against.

Even though the guest CPU utilization is above the DRSCPU threshold it was not enough to bring the VM CPU utilization above the threshold.

You should not publish the policy to all over the Oracle VM servers yet so they don’t know what the thresholds are.

The DRS policy updated is in direct conflict with the default DPM policy. You should correct this before continuing.

The virtual machine I/O path only uses the block device driver from dom0.

The virtual machine relies onemulation of the hardware in dom0 for block I/O.

The virtual machine I/O path includes the native block device drivers from the guest operatingsystem.

The virtual machine does not need a block device driver.

The virtual machine must provide emulation of the hardware through its own IOEMU drivers.

Configure the user name, password and IP address using Oracle VM agent.

Configure the user name, password and IP address using the Oracle VM manager.

Edit the IPMI.conf file on the Oracle VM server to enable automatic power setting.

Enable Wake-ON-LAN in the server BIOS.

Enable automatic power saving in Oracle VM Manager.

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 attachedto the virtual machine.

xm block-attach the disk to another virtual machine to inspect the file system and check module loading issues.

Use the xm save command to save the initial template in pristine form, then use xm restore to bring it back to the original configuration.

Use a snapshot of the initial template, and revert back to it whennecessary.

Use cleanup scripts to reset the IP addresses, remove files from temp directories, and replace application configuration files with defaults.

Modify the grub.conf file to include a -cleanup option in the grub command line, which will run the cleanup scripts added by Oracle.

Use JeOS with the -c option to include a cleanup script that will revert all files back to their initial state.

Turn on HA in the storage pool to create a redundant backup of virtual machines hosted in thatstorage pool.

Use network bonding to create multiple redundant paths to an iSCSI LUN.

Use multipathing to create multiple storage network paths toa SAN LUN.

Use Oracle Clusterware to create multiple paths to a SAN LUN.

Use Oracle Clusterware to create each storage repository on a different storage network.

It is the server in the server pool that will perform all I/O operations on the file system.

It is theNFS server that provide access to one or more shares.

It is the iSCSI server that will manager one or more LUNs.

It is the security server that will prevent unauthorized server pool members from accessing this share.

It is the admin server for this share.

The virtual machine was not exported properly using the Oracle VM Manager.

The virtual machine configuration file needs to be changed to update the new pathsto its virtualdisks.

The virtual machine configuration file lists bridges that do not exist on the new host.

The virtual machine has not been registered with Oracle VM yet.

It connects to a pool of virtual machines with a RDP service.

It connectsto any virtual or any physical machine with a RDP service.

It connects to any physical machine regardless of operating system.

It connects to any virtual or any physical machine with a VNC service.

You should always run a find command on dom0 to fill the file system buffer cache for bestperformance.

You should not run a find command on dom0 as it will use up Dom0 memory and potentiallycause double buffering with virtual machines.

When increasing load with additional virtual machines, you should always add more memory todom0.

When increasing load with additional virtual machines, you generally wont add more memory todom0.
