Improving Virtual Disk Performance

This section lists ways of improving the performance of virtual disks.

Preventing Partition Misalignment in Legacy Operating Systems

Virtual disks in virtual machines running legacy guest operating systems such as Windows Server 2003, Windows XP, Windows 2000, CentOS 5, or RHEL 5 may work slower because of partition misalignment. For solutions to this issue, see Aligning Disks and Partitions in Virtual Machines in the Parallels Cloud Server 6.0 User's Guide .

Maximizing Parallels Containers for Windows Performance

Containers created with Parallels Containers for Windows installed in a virtual machine may not work at maximum performance by default. To maximize their performance, make sure you install the update VZU460053 for Parallels Containers for Windows before you create or migrate any Containers. For more information on working with Parallels Containers for Windows, see the Parallels Containers for Windows User's Guide available at the Parallels website ( http://sp.parallels.com ).

Note: A write journal on a solid-state drive is highly recommended for virtual machines running Parallels Containers for Windows.
