Using Oracle VM Server 3.0.3 SDK

We released the Oracle VM Server 3.0.3 SDK which is delivered as Oracle VM Templates. The Oracle VM Server SDK Template provides an environment for third party drivers to be built for the Oracle VM Server for x86. This environment is being provided because the Oracle VM dom0 (management domain) only contains a minimum set of packages, and it does not provide the additional development packages needed for building modules. 

With the Oracle VM Server SDK, you can easily build a device driver for Oracle VM Server 3.0.3:

1) Set up a running Oracle VM environment including Oracle VM Manager 3.0 and Oracle VM Server 3.0. Refer to Oracle VM Documentation for additional details.

2) Download Oracle VM Server 3.0 SDK from Oracle Software Delivery Cloud. Select "Oracle VM Templates" from the "Select a Product Pack" pull-down menu, and choose "x86 64bit". Then locate the Oracle VM Server 3.0.3 SDK. Be sure to read the README. 

3) Import the Oracle VM Template for Oracle VM Server 3.0.3 SDK from Oracle VM Manager, and clone the VM from the imported template. Refer to the documentation: Managing Virtual Machines for specific instructions of importing the template and cloning a VM from the template.

4) Start the VM  - connecting to VM console and provide the network setting (DHCP or static IP, hostname, etc).

5) Log into the VM, download the driver and uncompress the driver source files. Then you are ready to build the driver for Oracle VM Server.

Note that Oracle provides support for third party drivers which have been developed by partners in the Oracle Partner Network. For drivers compiled by customers or partners using the SDK but that are not a part of the Oracle Partner Network, Oracle will provide a "reasonable effort" level of support as described by Oracle's "un-certified configuration" support policy. However, Oracle does not provide updates for any drivers built for Oracle VM Servers that have not been distributed by the Unbreakable Linux Network. To become an Oracle Partner, please refer to the page of Oracle VM Knowledge Zone for Partners.

Oracle VM 3.0 - Centralized Network Management

Oracle VM 3.0 was launched recently. I'd like to talk a bit more about the centralized network management capability in Oracle VM 3.0, one of new enhancements to benefit customers to easily build your virtualization infrastructure.

Oracle VM is designed to support sophisticated network configurations in order to provide the highest and most predictable performance, scalability, and availability for the virtual machines. The networking infrastructure in the Oracle VM environment needs to be able to support a number of functions. For example:

  • The guest network supporting IP traffic between Oracle VM Servers and the outside world
  • The management network between Oracle VM Servers and Oracle VM Manager
  • The storage network between the Oracle VM Servers and their storage sub-systems

Oracle VM provides the ability to separate networks in order to isolate traffic and maintain a predictable quality of service. Up to five separate network types can be defined from Oracle VM Manager: A server management network, live migration network, cluster heartbeat network, virtual machine IP network, and a storage network.

When you create an Oracle VM network, you map available network ports to a set of logical Ethernet networks from the Oracle VM Manager GUI. All Oracle VM Server logical network configuration and management tasks—such as creating networks, setting up NIC port bonding, and configuring VLAN Networks—are now performed using Oracle VM Manager.

To learn the networking capability and implement your networking design in Oracle VM 3.0, visit Oracle Learning Library for the series of demos on Oracle VM 3.0 networking, such as: 

  • Discover Oracle VM Servers
  • Create a Network for Virtual Machines
  • Create Bond Interfaces
  • Create a VLAN Group
  • Create Networks using VLAN Segments

You may also refer to Oracle VM documentation and white papers.

Configuring NTP Services for Oracle VM 3.0

In Oracle VM 3.0, when a new Oracle VM Server is discovered by Oracle VM Manager, NTP is automatically configured and enabled on the Oracle VM Server to ensure time synchronization. Oracle VM automatically configures the Oracle VM Manager machine as the NTP time source used by the Oracle VM Servers. This post will explain how to configure NTP on your Oracle VM Manager to provide time services.

Prior to starting this process, you should ensure that your Oracle VM Manager host is either registered with the Unbreakable Linux Network (ULN) or configured to use Oracle's public yum service.  Oracle Linux 5 servers registered with ULN can use either the up2date or yum tool to install updates. If you are not registered with ULN or you are using Oracle Linux 6, you can only use the yum tool.

The following procedures  should be carried out on the Oracle VM Manager host, unless otherwise specified.

Download and Install NTP

First, ensure the NTP package is installed by running (as appropriate):

# up2date -i ntp

or

# yum install ntp

Enable Upstream Synchronization

Once NTP is installed, we need to configure it to both synchronize with upstream servers as well as provide time services to the local network. To do this, open /etc/ntp.conf with your favourite text editor. The default /etc/ntp.conf file that ships with Oracle Linux is configured to use three public NTP servers as upstream time sources. You may want to check with your network administrator if time services are provided on your corporate network and replace these entries.

To change your upstream time servers, search /etc/ntp.conf for:

server 0.rhel.pool.ntp.org
server 1.rhel.pool.ntp.org
server 2.rhel.pool.ntp.org

And replace with entries that refer to your local time server names or IP addresses.

Configuring Downstream Access

Next, we need to allow the Oracle VM Servers to synchronize with this server. To do that, we need to disable the default "noquery" option for the Oracle VM Server Management network.

Again in /etc/ntp.conf, search for the following line:

#restrict 192.168.1.0 mask 255.255.255.0 nomodify notrap

Replace 192.168.1.0 with the network address for the Oracle VM Server Management network. You may also need to adjust the mask. Finally, remove the # character to uncomment this line. Once you've finished editing, save the file.

Start NTP and Check Upstream Synchronization

Once you've made the appropriate changes, start NTP by issuing the following command:

# service ntpd start

You should also set NTP to start automatically on boot:

# chkconfig ntpd on

Once NTP has started, you can check whether it has achieved upstream synchronization by using the ntpq tool:

# ntpq -p

This will output something similar to:

     remote           refid      st t when poll reach   delay   offset  jitter
==============================================================================
 lists2.luv.asn. 203.161.12.165   3 u   25   64    3    3.495  -3043.1   0.678
 yarrina.connect 130.95.179.80    2 u   27   64    3   26.633  -3016.1   0.797
 2402:d800:0:1:: 130.234.255.83   2 u   24   64    3    4.314  -3036.3   1.039

If everything is working properly, the delay and offset values should be non-zero and the jitter value should be below 100.

Test Downstream Synchronization

Once your NTP server is up and running, you can test from another server to ensure that NTP services are working. Note that it can take several minutes before your NTP server is able to provide time services to downstream clients. First, check the stratum level of your server:

# ntpq -c rv

assID=0 status=c011 sync_alarm, sync_unspec, 1 event, event_restart,
version="ntpd 4.2.4p8@1.1612-o Tue Jul  6 21:50:26 UTC 2010 (1)",
processor="x86_64", system="Linux/2.6.32-200.19.1.el6uek.x86_64",
leap=11, stratum=16, precision=-20, rootdelay=0.000,
rootdispersion=1.020, peer=0, refid=INIT,
reftime=00000000.00000000  Thu, Feb  7 2036 17:28:16.000, poll=6,
clock=d21d4a96.a26c5962  Fri, Sep 16 2011 14:09:58.634, state=0,
offset=0.000, frequency=0.000, jitter=0.001, noise=0.001,
stability=0.000, tai=0

If your server is still showing stratum=16, wait a few minutes and try again. It can take up to 10-15 minutes for an NTP server to stabilize sufficiently to lower its stratum level. Downstream clients will not synchronize with a server at stratum level 16.

Once the stratum level has dropped, log in to an Oracle VM Server or any available Linux host on your network and issue the following command:

# ntpdate -d manager.server.name

This will run the ntpdate in debug mode, which checks to see if the remote time server is available. If the stratum is still too high, you may see "Server dropped: strata too high". In which case, wait until the previous command shows that your stratum level has dropped from 16. A successful debug run should finish with a line similar to:

16 Sep 13:58:25 ntpdate[1603]: step time server 192.168.168.6 offset 3.009257 sec

Once you have confirmed that NTP is working, you should not need to check this  again.

Troubleshooting

NTP communicates over UDP port 123. Ensure that this port is opened on your Oracle VM Manager machine. Also, NTP clients will only synchronize with servers that have a lower than 16 stratum. This will only happen several minutes after upstream synchronization has settled. Ensure that your upstream synchronization is working prior to testing downstream.

Changing the ovs-agent password on Oracle VM Server 3.0

The Oracle VM Server password is used by Oracle VM Manager when you discover an Oracle VM Server. You set this password during the Oracle VM Server installation. I've had a few users ask me how to change the ovs-agent password on an Oracle VM Server after installation. This post will detail how to change the password on an existing Oracle VM Server, as well as generate an Oracle VM Server password for use in a kickstart file for automated installs of Oracle VM Server.

Changing an existing agent password

To change an existing Oracle VM Server's password, use the ovs-agent-passwd command:

# ovs-agent-passwd <username> <password>

The username used by Oracle VM Manager to communicate with the agent is oracle, so the command would look like this:

# ovs-agent-passwd oracle MyNewPasswordIsVerySecure

To enable batch discovery of Oracle VM Servers in the Manager, ensure that the agent password is the same on all the servers you want to discover in a single job.

Creating an encrypted password for kickstart

The ovs-agent-passwd utility can also be used to generate an encrypted password hash that can be used in kickstart files for automated builds of Oracle VM Server:

# ovs-agent-passwd --encrypt <password>

This will output the encrypted password hash that can be used by adding the following line in the kickstart file:

ovsagent --iscrypted <password hash>

Webcast: Best Practices for Speeding Virtual Infrastructure Deployment with Oracle VM

We announced Oracle VM Blade Cluster Reference Configuration last month, see the blog. The new Oracle VM blade cluster reference configuration can help reduce the time to deploy virtual infrastructure by up to 98 percent when compared to multi-vendor configurations. Customers and partners have shown lots of interests. Join Oracle's experts to learn the best practices for speeding virtual infrastructure deployment with Oracle VM, register the webcast (1/25/2011) here.

Virtualization has already been widely accepted as a means to increase IT flexibility and help IT services align better with changing business needs. The flexibility of a virtualized IT infrastructure enables new applications to be rapidly deployed, capacity to be easily scaled, and IT resources to be quickly redirected. The net result is that IT can bring greater value to the business, making virtualization an obvious win from a business perspective.

However, building a virtualized infrastructure typically requires assembling and integrating multiple components (e.g. servers, storage, network, virtualization, and operating systems). This infrastructure must be deployed and tested before applications can even be installed. It can take weeks or months to plan, architect, configure, troubleshoot, and deploy a virtualized infrastructure. The process is not only time-consuming, but also error-prone, making it hard to achieve a timely and profitable return on investment. 

Oracle is the only vendor that can offer a fully integrated virtualization infrastructure with all of the necessary hardware and software components. The Oracle VM blade cluster reference configuration is a single-vendor solution that addresses every layer of the virtualization stack with Oracle hardware and software components, see the figure below. It enables quick and easy deployment of the virtualized infrastructure using components that have been tested together and are all supported together by Oracle.
