How Cluster Server (VCS) manages Virtual Machine (VM) guests
High-level overview of how VCS manages VM guests.
Physical machines form a cluster with VCS installed on them.
For information about installing VCS, see the Veritas InfoScale Installation Guide.
CPU and memory resources are made available to create VM guests on all nodes in the cluster.
VCS is installed on all the hosts to manage the VM guest.
The operating system is installed on the VM guest.
Note:
The VM guest can be created on an image file or on a shared raw disk, provided the disk names are persistent across all the physical hosts.
The VM guest is configured as a KVMGuest resource in VCS.
For detailed instructions on creating and configuring a VM guest, see the installation section in the Red Hat Enterprise Linux (RHEL) or SUSE Linux Enterprise Server (SLES) virtualization documentation.
To configure a VM guest for a physical machine to physical machine (PM-PM) configuration, the following conditions apply:
You must configure a VM guest on one node with operating system installed on a shared storage accessible to all the VCS cluster nodes.
Ensure that the image file resides on the shared storage so that the virtual machines can fail over across cluster nodes.
You can configure the first VM guest using the standard installation procedure.
See Installing Veritas InfoScale Solutions in the kernel-based virtual machine environment.
Bundled agents are included with VCS for managing many applications. The KVMGuest agent is included and can be used to manage and provide high availability for KVM guests. For information on KVMGuest agent attributes, resource dependency and agent function, refer to the Cluster Server Bundled Agents Reference Guide.
