Containers 4.7 on servers running Red Hat Enterprise Linux 6 and use this operating

system for creating new Containers.

• New memory management scheme. Parallels Virtuozzo Containers 4.7 introduces a

new scheme for managing memory-related parameters in Containers—

VSwap

. Like

many other memory management schemes used on standalone Linux computers, this

scheme is based on two main parameters: RAM and swap.

• IPv6 support. Parallels Virtuozzo Containers 4.7 provides full support for using IPv6

addresses with Containers, including IPv6 support by Parallels Virtual Automation.

• Parallels Virtual Automation (PVA) 4.6.3 support. You can use Parallels Virtual

Automation 4.6.3 to manage Hardware Nodes running Parallels Virtuozzo Containers

4.7. You can choose to install the PVA components (PVA Agent and PVA Master Node)

during the product installation.

• Persistent tap devices support. Parallels Virtuozzo Containers 4.7 now supports

creating persistent tap devices in Containers.

5. KNOWN ISSUES AND RESTRICTIONS

The list of known issues for Parallels Virtuozzo Containers 4.7 is given below.

 After installing Parallels Virtuozzo Containers 4.7 on servers that run Red Hat Enterprise

Linux 5.6 or CentOS 5.6, you may fail to boot into the new kernel. To work around the

problem, use the

nomodeset

option when booting into the Parallels Virtuozzo

Containers kernel.

 Logging in to a Container using the

vzctl enter

command may fail if you execute the

command right after starting the Container. To work around the problem, wait for a

while, and try to run the command again.

 Moving back a Container that was created on an x86 Node and then migrated to an

x64 Node may fail.

 Migrating a Container running an x86 guest operating system from a Node with the

VDSO (Virtual Dynamically-linked Shared Object) library turned on to an x64 Node may

fail. By default, the VDSO library is off on Nodes running Red Hat Enterprise Linux

(RHEL) 5 and CentOS 5 and is on Nodes with RHEL 6.

Note: This issue does affect the migration of Containers between Nodes that both run

the x64 version of RHEL 6, irrespective of the VDSO state.

 Migrating a Container between Hardware Nodes may fail if the Container private area is

stored on a shared storage and the

vzcache

exists for the Container (the cache might

be created, for example, using the

vzkpg localinstall

command).

 Migrating Containers using the online migration type is not supported from

o Hardware Nodes that run Parallels Virtuozzo Containers 4.7 to Nodes with Parallels

Virtuozzo Containers 4.0 and 4.6.
