This improves total network throughput and increases fault tolerance in the event of hardware failures. The SLB balancing algorithm has been modified to reduce load on switches in large deployments.
When these extensions are deployed VMs cannot impersonate any other VM, or intercept traffic intended for any other VM. This increases security in environments where VMs cannot be fully trusted.
For detailed configuration see the XenServer 6. This improvement enables administrators using XenServer 6. IPv6 Guest Support : enables the use of IPv6 addresses within guests allowing network administrators to plan for network growth.
This enables the use of 3rd party tools to deliver and manage the installation and upgrade of the XenServer device drivers. Ongoing Improvements Supported number of VMs per host increased to XenCenter: configuration of performance graphs simplified; assignment of IP addresses simplified.
NET 3. NET 4. Refer to CTX for details. Updated Open vSwitch: v1. Refer to CTX for configuration details. Known Issues and Errata This section details known issues with this release and any workarounds that can be applied. Before attempting to upgrade a XenServer host to version 6. Customers running these guests who have already upgraded their host to XenServer 6.
Once the host is upgraded, you must update the guest kernels using the one supplied on the XenServer 6. Customers should either fix the access to the storage repository or remove it from the XenServer pool before restarting the wizard. When installing XenServer from a network repository including when using the XenCenter Rolling Pool Upgrade wizard , you must configure the DHCP server to provide the domain-name option, otherwise DNS will not work correctly, which can lead to a failed installation.
Storage specified during installation for both the primary-disk and the guest-disk will be formatted. Intel Errata for Nehalem and Westmere CPU implementations of C-states may lead to system instability, apparently random freezes or reboots — including during installation.
Customers should ensure that the FCoE switch is correctly configured to accept such logins, otherwise access to the storage may be lost. If your environment requires more frequent rebalancing, refer to CTX for instructions on how to change the bond rebalancing intervals.
Customers should follow the procedure in CTX Customers should use the vSwitch Controller to create QoS settings.
Insufficient disk space on the dom0 filesystem can cause the Service Pack installation to fail with the error message: The uploaded patch file is invalid. Customers must ensure that the Pool Master is restarted before any of the pool members. This happens automatically for users applying the Service Pack using the Install Update wizard in XenCenter, unless they choose to perform the post-update tasks manually.
Customers who have installed device drivers should download and install the compatible versions before applying the Service Pack. After applying the Service Pack, customers will be notified that the XenServer Tools are out of date. If customers have installed a hotfix of the form XS62Ennn, which has a sequence greater than XS62E, they should also ensure to install the Service Pack and then install the corresponding hotfix for the Service Pack of the form XS62ESP1nnn , in order to achieve the same patch level.
Customers wishing to install Service Pack 1 will need to do a fresh installation of XenServer 6. In addition, this Service Pack includes the following previously released hotfixes. Installing the update using XenCenter Ensure that you have at least MB of disk space on the dom0 filesystem of EACH host in the pool before uploading the xsupdate file.
Download the update to a known location on a computer that has XenCenter installed. This displays the Install Update wizard. Click Next to start the Wizard.
Click Add to upload a new update. Browse to the location where you downloaded the Service Pack, select it, and then click Open. Select the hosts you wish to apply the Service Pack to, and then click Next. Follow the recommendations to resolve any upgrade prechecks and then click Next.
Choose how to perform the post-update tasks. In the Post update options section, select automatically or manually, and then click Install update. When the installation process is complete, click Finish to exit the wizard. You must reboot your hosts sequentially, starting with the Pool Master. Customers who select to automatically perform the post-update tasks should note that XenCenter reboots each host sequentially starting with the Pool Master, where possible VMs will be migrated to other running hosts to avoid VM downtime.
