Restrictions

HP storage controllers with software RAID features are not supported for use with RAID enabled. This is a permanent restriction due to a lack of drivers from HP.

V2.11.0 (7-Mar-2016)

The following new features and enhancements have been added in this release of vtServer:

  • Added N_Port ID Virtualization (NPIV) support for Fibre Channel. This allows virtual Alpha systems sharing a single host FC adapter to utilize isolated storage pools.

Restrictions

HP storage controllers with software RAID features are not supported for use with RAID enabled. This is a permanent restriction due to a lack of drivers from HP.

V2.10.1 (7-Sep-2015)

The following new features and enhancements have been added in this release of vtServer:

  • vtMonitor supports the new Microsoft Edge browser.
  • Logical tapes can now be compressed/decompressed as they are written/read.

  • A new version of the host control kernel provides supprt for new processor platforms and devices.
  • UEFI boot support has been added.
  • Direct emulation of the VAX 4000-90 has been added..

Restrictions

None

V2.9.1 (4-Nov-2014)

The following new features and enhancements have been added in this release of vtServer:

  • The vtVAX 7000 emulation has been extended to 64 bits and now supports emulation of up to 6 CPUs and 3.5 GB of memory.
  • New vtServer installations assign network device names based on PCI bus ID rather than MAC address. This change will eliminate device name changes when network adapter cards are replaced. This change does not apply to updates of existing vtServer installations to avoid unintentional device name changes.
  • Network gateway addresses are now assigned to each interface. A default gateway address may be defined.
  • 10 Gbit Ethernet adapters are now supported.
  • The vtServer product update process now searches for .tar files in addition to .tgz files. Some versions of Microsoft Internet Explorer rename .tgz files to .tar on upload.
  • Configuration names that begin with a period are now supported.
  • Emulators configured to auto-start are not started until all network adapters have initialized and are ready for use.

The following security-related enhancements are present in vtServer V2.9.1:

  • bash updated to version 4.1 patch 17.

vtServer has never been vulnerable to the bash "Shell Shock" exploit because there is no ability to execute arbitrary shell scripts.

Restrictions

  • Container files for logical disk and tape devices may no longer be created in the partition the vtServer software is running from. This change was made to prevent large container files from using all the free disk space, which will cause vtServer to crash.
  • The vtServer software must be installed on a disk that is directly connected to the host system. Installation on SAN disks is not supported. SAN storage may be used for physical or logical devices presented to the emulated Alpha and VAX systems.

V2.9 (7-Jul-2014)

The following new features and enhancements have been added in this release of vtServer:

  • iSCSI disks supported as host storage
  • Auto-sensing of Fibre Channel device configuration changes
  • vtServer installation scripting capability
  • Site-defined pre-login message option
  • Additional alerts/email notifications
  • Virtual network switch option to disable spanning tree protocol
  • vtAlpha Floating Point instruction performance improved
  • DE600 network interface emulation
  • Extended PBXDA serial line interface logging capability
  • vtVAX support for the virtual network switch
  • vtVAX support for binary mode serial-over-IP connections

The following security-related enhancements are present in vtServer V2.9:

  • OpenSSL updated to V1.0m.
  • Apache HTTP (web) server updated to V2.2.27.
  • User passwords are masked in data copied to Support Info files.
  • Coredump files are encrypted to secure contents in transit to our support team.

The OpenSSL library used by vtServer was not vulnerable to the Heartbleed vulnerability (CVE-2014-0160). Both OpenSSL and the Apache HTTP server contain all available security patches as of the vtServer release date.

V2.8.3 (1-Mar-2014)

  • Support for DEC LK-series keyboards in X-windows server to allow use of extended function and keypad keys.
  • Support for additional ATI and NVIDIA display adapters. Drivers needed for special cases (3D graphics, extended OpenGL functionality, and more than two adapters) are provided with the distribution kit and may be installed as needed.
  • Support for solid state disks.
  • WWID, controller ID, and LUN have been added to the vtMonitor storage information display for Fibre Channel devices.
  • Boot option to force a re-scan of configured network devices. This option is used so that vtServer can recognize network interfaces that were added after the software was installed.
  • The vtMonitor Configuration Backup now saves the bindings between device names and physical devices. This prevents device names from changing after a re-install or clean upgrade of vtServer.
  • The Alpha emulation status indicator in the vtMonitor configuration management list now displays an "H" to indicate the instance is active and halted at the console prompt. This feature will be added for VAX emulations in a future release.
