NFS repositories are excellent for storing guests' root file systems.

NFS is a more expensive option than iSCSI or SAN fabrics.

OCFS2 must be used as the filesystem format for volumes exposed through NFS.

NFS shares mounted directly in a guest require the DM-NFS driver to be installed on the guest.

NFS is supported for use in RAC only when mounted from the guest (not domO).

Use PV with Microsoft's Windows 2003 64-bit with a paravirtualized kernel

Use HVM witha 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.

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.

config_network.py -l will show which network interfaces are in use, and which are having problems.

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.

System-config-network will list the virtual interfaces, which can be inspected to see which are having problems.

ifconfig -a will show a list of all network interfaces and their current status, which will help determine which bridge is having problems.

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

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.

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.

The server where the template is deployed should have enough local disk to store the virtual disk images.

The server mustbe in the clustered server pool.

The server must have more memory then the host that was converted.

The P2V converted virtual machine must have a unique name.

The server in the server pool must have hardware virtualized support (have intel VT-X orAMD-v chip feature).

The LUN should be formatted with ext3 from every participating node in the cluster.

The LUN should be formatted with ext3 from a single node in the cluster.

The LUN should be formatted with OCFS2 fromevery participating node in the cluster.

The LUN should be partitioned, and then formatted with OCFS2 from every participating node in the cluster.

The LUN should be formatted with OCFS2 from a single node in the cluster.

When you restore a server pool, all the data stored In the Oracle VM Manager database isdeleted, and the data in the server pool master and virtual machine servers is used to restock the database.

When you restore a server pool, all servers are removed from the pool, and the data in the database is removed, restoring the server pool to its initial state.

When you restore a server pool, all the data stored in the server pool master will be deleted, and will be synchronized with the latest information from the Oracle VM Manager database. The server pool master is responsible for updating the individual Oracle VM servers' agent databases.

When you restore a server pool, a signal is sent out to each server in the pool, which responds swith the current state of all of the virtual machines it hosts. This data is used to restore the data in the Oracle VM database.

On each Oracle VM server, stop the agent, delete all files in /etc/ovs-agent/db, then restart the agent.

From the Oracle VM Manager, select the Server Pools tab and do a Restore operation on the server pool.

On the server pool master, stop the agent, delete all files in /etc/ovs-agent/db, then restart the agent.

From theOracle VM Manager, select the server pool master on the Servers tab, and Reboot the server.

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

Virtual machine is configured improperly. Navigate to edit the virtual machine setting. In the Oracle VM manager on the first pagechange the domain type from XEN PVM to XEN HVM using the pull down menu and then start the machine.

Hardware virtualized CPU extension VT-X or AMD-V are not enabled is the machine BIOS setting. Enable the feature in the BIOS for virtualization support and to enable the virtual machine to start.

The imported template is not compatible with the OVM server. Locate the vm.conf file for the Solaris VM edit the file and add the line “builder=HVM” save the file and start the VM.

Server does not support the hardware virtualization. Build the Solaris VM on the server that support hardware virtualization.
