Moreover, with a single master image stored on a virtual disk, organizations don’t have to maintain dozens of disk images, even as they add more machines to their environments. Since PVS requires VMs to boot and pull the master image over the network, it is ideal for on-premises virtualization environments. This way, your VMs are assured of always running the latest copy of the master image. PVS will then stream the new master image to the VMs. When there are changes in the master image, the VMs need to be rebooted. When the VM is rebooted, the cache disk gets wiped. The VM master image is then streamed from the server to the VM’s cache disk, which is also used for write operations while the VM is in use. In a Citrix environment that uses PVS, a boot file is downloaded from the provisioning server when a VM is started. What Is Citrix PVS, and How Does It Work? While Citrix PVS is ideal for physical machines and VMs, its reliance on a network connection means that it can only be used on-premises, unlike another Citrix image management technology, Machine Creation Service (MCS), which can also be used on the public cloud. PVS streams a master VM image located on a server file-share to either a VM or physical machine in an organization’s on-premises virtual desktop infrastructure (VDI).
Citrix Provisioning Services (PVS) is used to deploy and manage virtual machine (VM) images in Citrix Virtual Apps and Desktops.
