Monitoring XenServer Alerts visible from XenCenter GUI Can be emailed to resource pool admin Can support custom fields and tags…

You can back up a managed server to a XenServer backup file (.xbk) that can then be used to restore the server in case of hardware failure. Note that this will back up just the server itself, but not any VMs that might be running on it. We recommend that you back up your servers…

You enable HA for a resource pool using the Configure HA wizard. The wizard takes you through the HA configuration process, step-by-step, calculating the server failure limit for the pool given the available resources and the HA restart priorities you specify. To open the Configure HA wizard: in XenCenter, select the pool, click on the HA tab, and then click Configure HA….

Use the XenCenter Configure DR dialog box to identify storage repositories (SRs) where the metadata for a pool – configuration information about all the VMs and vApps in the pool – will be stored. This metadata will be updated whenever you make changes to VM or vApp configuration within the pool. To configure DR on the primary…

The XenServer Disaster Recovery (DR) feature is designed to allow you to recover virtual machines (VMs) and vApps from a catastrophic failure of hardware which disables or destroys a whole pool or site. For protection against single server failures, you can use XenServer High Availability to have VMs restarted on an alternate server in the same pool….

If more servers fail than have been planned for, then an HA recovery operation begins. The HA restart priority is used to determine which VMs are restarted, while the order in which individual VMs are started is determined by their start order and delay interval values, ensuring that the most important VMs are restarted first. HA restart…

XenServer High Availability (HA) allows virtual machines to automatically be restarted in the event of an underlying hardware failure or loss of any managed server. HA is about making sure that important VMs are always running in a resource pool. With HA enabled, if one of your servers fails, its VMs will be intelligently restarted…

Before configuring the below steps, make sure you add some additional hard disk(I mean space) to your freenas machine. Open a browser and login to FreeNAS 8.2. Navigate to Storage > Active Volumes:  Click Volume Manager. Enter a Volume Name, select disk(s), select Filesystem type (ZFS has some neat features), then click Add Volume: Click the Create ZFS Volume button: Enter a ZFS Volume Name, specify…

Workload Balancing is a XenServer appliance that balances your pool by relocating virtual machines onto the best possible servers for their workload in a resource pool. For example, Workload Balancing can: Balance virtual-machine workloads across hosts in a XenServer resource pool Determine the best host on which to start a virtual machine Determine the best…
