1. About This Release

Parallels Server 4 for Mac has a host of major new features and improvements in comparison with version 3.0, making it a true next-generation virtualization solution suitable for organizations seeking to consolidate and optimize their IT infrastructure.
 
2. What’s New

 

Parallels Server for Mac includes the following new features and enhancements:
 

- Parallels Server for Mac can be installed on Macs running Mac OS X Server v10.6 Snow Leopard or Mac OS X v10.6 Snow Leopard.

- You can now create virtual machines running the following guest operating systems: Mac OS X Server v10.6 Snow Leopard, Windows 7, and Windows Server 2008 R2.

- The overall stability of Parallels Server for Mac has been significantly improved since the previous release, especially the support for running Mac OS X Server v10.6 Snow Leopard in virtual machines.

- The installer now checks for available updates before installing Parallels Server for Mac and installs the most recent version.

- Parallels Server for Mac supports the creation of virtual networks. A virtual network acts as a binding interface between a network adapter on a virtual machine and the corresponding physical or VLAN adapter on the Parallels server, and allows you to include virtual machines in different networks.

- The functionality of Parallels Management Console, the main cross-platform tool for managing Parallels Server for Mac and virtual machines, has been significantly improved and enhanced since the previous release.

- A new "prl_disk_tool" utility is included in Parallels Server for Mac. This utility allows you to resize and compact virtual disks in your virtual machines.

- A function displaying the disk space and network usage of your server and virtual machines has been integrated into Parallels Management Console.

- You can now create consistent, full, and incremental backups of your virtual machines and store them on both local and remote servers.

- The following migration types are supported in Parallels Server for Mac:

 * Migrating virtual machines between Parallels servers, including “warm migration,” when the running virtual machine is moved to another Parallels server, without any interruption in service.

 * Migrating Linux and Windows physical servers to virtual machines.

 * Migrating Containers to virtual machines.

 * Migrating third-party virtual machines (VMware, Microsoft Virtual Server, and Virtual Box) to Parallels virtual machines.

 This functionality is available in both the "prlctl" utility and in Parallels Management Console.

- Most of a virtual machine’s network settings (IP address, network mask, and default gateway) can now be configured from the physical server using both the "prlctl" utility and Parallels Management Console. For this feature to work, Parallels Tools must be installed on the virtual machine.

- You can now execute arbitrary commands inside virtual machines by running them from the physical server. For this functionality to work, Parallels Tools must be installed on the virtual machine.

- You can now gain access to the command line of a virtual machine and execute various commands in it directly from the Parallels server, without needing to log in to and provide administrative credentials for the guest OS.

- Parallels Server for Mac supports the setting of user passwords for virtual machines from the physical server using both the "prlctl" utility and Parallels Management Console. For this functionality to work, Parallels Tools must be installed on the virtual machine.

- The Express installation mode has been enhanced with the possibility to install Windows 7, Red Hat Enterprise Linux, Ubuntu, and Fedora operating systems in "unattended" mode.

- You can now change Windows unique security identifiers (SIDs) when cloning a virtual machine or deploying a virtual machine from a template. For this feature to work, Parallels Tools must be installed on the virtual machine.

 

3. Bugs Fixed
 

Many bugs from the previous release have been fixed in Parallels Server 4 for Mac. Here is a small sample of them:

- It is impossible to install and use Parallels Server 4 for Mac on servers running Mac OS X 10.6 Snow Leopard.

- It is impossible to install and use Mac OS X 10.6 Snow Leopard Server inside virtual machines.

- A virtual machine may consume a lot of CPU time, even if it is idle.

- Resuming a suspended virtual machine with Windows may result in a BSOD on this virtual machine.

- Reverting to a snapshot of a Windows virtual machine may result in a BSOD on this virtual machine.

- Connecting to a Parallels server using Parallels Management Console on a remote computer may lead to a high CPU usage on this Parallels server.

- The performance of WikiServer on a virtual machine needs to be improved.

 

4. Known Issues and Restrictions
 

The list of known issues for Parallels Server 4 for Mac is given below:

- Encoding video with Podcast Producer on a virtual machine may take much more time than on the host operating system.

- Servers running Mac OS X Leopard Server may crash while running several huge virtual machines. The problem does not exist on servers with the x64 version of Mac OS X Snow Leopard.

- Sometimes, Parallels Management Console may stop working when connecting to the Parallels server. To work around this problem, restart Parallels Management Console.

- A virtual machine with a large amount of RAM may hang when installing the SUSE operating system on it.

- It may be impossible to connect to a virtual machine using Parallels Management Console after stopping it forcibly or resetting the virtual machine. To work around this problem, restart Parallels Management Console.

- An empty virtual machine cannot be backed up.

- If a Windows virtual machine cannot be shut down gracefully (e.g., due to some unfinished work), it will be forcibly stopped after a while.

- SmartMouse may not work properly in virtual machines running SLES 11.

- Updating Mac OS X 10.5.3 to 10.5.8 on a virtual machine may take a long time.

- A kernel panic may occur on a Mac OS X virtual machine after resuming it. To work around this problem, use the following system flag: "kernel.paravirt.enable=0."

- It is impossible to write files to the FAT32 virtual disks mounted to the Mac OS X host operating system.

- A number of compatibility problems exist with Parallels Server 3 for Mac snapshots.

- The license installed on the Parallels Server may be lost after upgrading this server from Parallels Server 3.0 for Mac to Parallels Server 4 for Mac.

- You may have problems using Parallels Mounter to manage virtual machines whose disks are formatted with the HFS+ file system. For example, you may fail to rename or delete folders and files on such disks.

- Parallels Mounter does not support the management of dynamic and LVM disks.

- Parallels Mounter does not work on servers running 64-bit versions of Mac OS.

- You may have problems managing virtual machines that reside on Network File System (NFS) shares.

- Parallels Transporter does not support the migration of computers whose disks are formatted with ext4.

- You may fail to start a virtual machine migrated using Parallels Transporter if the original system was incorrectly shut down before the migration.

- Parallels Transporter can migrate bootable LVM partitions and dynamic disks as data disks only.

- Parallels Transporter does not support the migration of third-party virtual machines with SCSI disks.

- Sometimes, Parallels Transporter may fail to convert virtual machines created with VMware Fusion or VMware ESX.

- A virtual machine may crash after hibernating. To work around this problem, suspend the virtual machine instead of hibernating it.

- Dynamic disks of a backed up virtual machine may become offline after restoring the virtual machine.

- The "prl_disk_tool" utility does not support the resizing and compacting of dynamic and LVM disks.

- The upgrade from Parallels Server 3.0 to Parallels Server 4 for Mac may fail. To work around the problem, stop all virtual machines on the server, remove Parallels Server 3.0 from the server, and then perform a clean installation of Parallels Server 4 for Mac.
