Provisioning Services (PVS) is software streaming technology that delivers patches, updates, and other configuration information to multiple virtual desktop endpoints through a shared desktop image. For the most recently updated content, see the Citrix Provisioning current release documentation.
The Update Itself
- Boot up your master VM, if it's offline.
- Log in to your master machine via console or RDP.
- Apply changes as desired.
- Run BIS-F to seal and shutdown the master image.
- Login to your hypervisor and manually create a snapshot.
- Select “Update Machines” inside Citrix Studio:
Citrix and VDI: Citrix Virtual Apps (formerly Citrix XenApp) is an application delivery solution that allows access to Windows-based applications to any device compatible with Citrix Receiver. A VDI desktop is a desktop running on a server in the datacenter that a user can access from virtually any device.
A vDisk acts as a hard disk for a target device and exists as disk image files on a Citrix Provisioning server or on a shared storage device. A vDisk can be shared (Standard Image) by one or more target devices, or it can exist for only one target device to access (Private Image).
MCS will automatically create a snapshot of the master image you select during Machine Catalog creation. You can also manually create a snapshot and select it during the Machine Catalog creation wizard. This step ensures a full snapshot is created on your storage repository alongside the master virtual machine.
When the vDisk is shared among several different machines using Citrix Provisioning, those machines perform a network boot to the vDisk and overlay their unique identities (MAC address, machine name, etc). This appears to be a type of cloning operation, but standard cloning preparations do not work as expected.
Citrix – A Virtualization SolutionCitrix software publishes virtualized Windows applications, desktops and resources to remote users. Citrix Virtual Apps and Desktops works with Microsoft Remote Desktop Services (RDS), utilizing their High Definition Experience (HDX) protocol for data transferring.
The Master of Computer Science (MCS) is a professionally-oriented, course-based program for students who wish to enhance their careers with advanced knowledge of computer science.
A persistent vegetative state (PVS) or post-coma unresponsiveness (PCU) is a disorder of consciousness in which patients with severe brain damage are in a state of partial arousal rather than true awareness. After four weeks in a vegetative state (VS), the patient is classified as in a persistent vegetative state.
PVS Services: SOAP Service: Simple object access protocol. This is the XML based service which communicate between applications. Soap Service is for PVS Console and management operations only and will not effect streaming at all. If this service is stopped any activity that involves the PVS GUI console will stop.
Virtual Delivery Agent (VDA)The VDA is installed on each physical or virtual machine in your site that you make available to users. Those machines deliver applications or desktops. VDAs also verify that a Citrix license is available for the user or session, and apply policies that are configured for the session.
In PVS, the term “write cache” is used to describe all the cache modes. The write cache includes data written by the target device. If data is written to the PVS server vDisk in a caching mode, the data is not written back to the base vDisk. Cache in device RAM. Cache on device RAM with overflow on hard disk.
TFTP services reads associated bootstrap, boot file (ARDBP32. BIN) information to provide back to the client as a usable network boot server. The bootstrap file typically houses connectivity information for all of the PVS servers under your associated PVS Farm.
A machine catalog is a collection of identical machines. They can be either virtual or physical. They can host either a supported desktop or server operating system. You create delivery groups to provide desktops and applications to the users; in a delivery group, you can mix machines from different machine catalogs.
Citrix Virtual Desktops (aka XenDesktop) Setup Wizard. The easiest way to create a bunch of Target Devices is to use the Citrix Virtual Desktops Setup Wizard that is built into the Citrix Provisioning Console. This wizard used to be named XenDesktop Setup Wizard.
In a Citrix application delivery setup, IT configures central servers to host applications and resources. The user sends keystrokes and mouse clicks to the server and receives screen updates. The client device needs the Citrix Receiver installed on it to gain access to hosted resources from a Windows Server.
To enable automatic vDisk updates:
- Right-click on the Site in the console, then select the Properties menu option. The Site Properties dialog appears.
- On the vDisk Update tab, check the box next to Enable automatic vDisk updates on this site.
- Select the server to run vDisk updates for this site, then click OK.
To delete machines from a catalog:
- Select Machine Catalogs in the Studio navigation pane.
- Select a catalog and then select View Machines in the Actions pane.
- Select one or more machines and then select Delete in the Actions pane.
login to your master image virtual machine and update it and shutdown. In your xendesktop server, open powershell and load citrix snapins. Get-ProvScheme -ProvisioningSchemeName “Machine catalog name” use this command to see the existing master image for your machine catalog.
To add or remove a Remote PC Access machine catalog association with a Delivery Group:
- Select Delivery Groups in the Studio navigation pane.
- Select a Remote PC Access group.
- In the Details section, select the Machine Catalogs tab and then select a Remote PC Access catalog.
