Wilmington, North Carolina once had a thriving Black middle class and an elected interracial government. In 1898 white supremacists used violence to overthrow that government, kill Black residents and drive many others from the city.

Virtual Iron Software, was located in Lowell, Massachusetts, sold proprietary software for virtualization and management of a virtual infrastructure. Co-founded by Alex Vasilevsky,[1] Virtual Iron figured among the first companies to offer virtualization software to fully support Intel VT-x and AMD-V hardware-assisted virtualization.[2]
As of May 2009[update] Oracle Corporation agreed to acquire Virtual Iron Software, Inc., subject to customary closing conditions. Oracle now declines to offer any updates or patches for current customers, even updates and patches developed before the purchase.[3] On June 19, 2009, The Register reported that Oracle had killed the Virtual Iron product.[4]
Virtual Iron software ran unmodified 32-bit and 64-bit guest operating systems with near-native performance[citation needed]. A virtualization manager offered access to control, automate, modify and monitor virtual resources. Virtualization services were automatically deployed on supported hardware without additional software. The platform was based on the open source Xen hypervisor.[5] Virtual Iron, like other virtualization software, provided server consolidation, business continuity and capacity management.[6]
The Virtual Iron platform consisted of a virtualization manager, virtualization servers and a hypervisor. The virtualization manager (VI-Center), a Java-based application, allowed for central management of the virtualized servers. A physical server could have many virtualized servers, which ran as unmodified guest operating systems.
Virtual Iron could use both physical-storage or virtual-storage access models. However, the use of a virtual-storage access model leveraged SAN storage to create a fault-tolerant iSCSI or Fibre Channel based cluster of virtual nodes. The VI Center installed on both Windows and Linux. After installation, the administrator had to configure a "management network" for the purpose of communicating with nodes in the cluster. The VI Center used the management network to PXE boot any server that was connected and correctly configured (for PXE boot).
The included LiveRecovery tool could configure high availability. Additionally, CPU or power-consumption load-balancing was configurable using the LiveCapacity or LivePower tools respectively. Additional features included disk and virtual machine cloning (snapshots), IPMI/ILO support, etc.
Virtual Iron had implemented full virtualization (requiring hardware-assisted virtualization which it called native virtualization) over paravirtualization. Native virtualization allowed for unmodified guest operating systems and had the advantage of hardware advances for better performance. Virtual Iron, Inc claimed to have pioneered the implementation of native virtualization.[7] Virtual Iron discussed paravirtualization and native virtualization in its blog:
Virtual Iron has decided against paravirtualization in favor of "native virtualization." With hardware advances coming out of Intel and AMD, we see native virtualization capable of matching physical hardware performance without any of the complexity and engineering efforts involved in paravirtualizing an OS. From our discussions with a broad range of users, they simply do not want to roll out modified OSs unless the trade-off is heavily in their favor. This Faustian trade-off is no longer necessary.[8]

A virtual security switch is a software Ethernet switch with embedded security controls within it that runs within virtual environments such as VMware vSphere, Citrix XenDesktop, Microsoft Hyper-V and Virtual Iron. The primary purpose of a virtual security switch is to provide security measures such as isolation, control and content inspection between virtual machines. Virtual machines within enterprise server environments began to gain popularity in 2005 and quickly started to become a standard in the way companies deploy servers and applications. In order to deploy these servers within a virtual environment, a virtual network needed to be formed. As a result, companies such as VMware created a resource called a virtual switch. The purpose of the virtual switch was to provide network connectivity within the virtual environment so that virtual machines and applications could communicate within the virtual network as well as with the physical network. This concept of a virtual network introduced a number of problems, as it related to security within virtual environment, due to only having virtual switching technology within the environment and not security technologies. Unlike physical networks that have switches with access control lists (ACLs), firewalls, antivirus gateways, or intrusion prevention devices, the virtual network was wide open. The virtual security switch concept is one where switching and security have joined forces, so that security controls could be placed within the virtual switch and provide per-port inspection and isolation within the virtual environment. This concept allowed security to get as close as possible to the end points that it intends to protect, without having to reside on the end points (host-based on virtual machines) themselves. By eliminating the need to deploy host-based security solutions on virtual machines, a significant performance improvement can be achieved when deploying security within the virtual environment. This is because virtual machines share computing resources (e.g. CPU time, memory or disk space) while physical servers that have dedicated resources. One way of understanding this, is to picture 20 virtual machines running on a dual-CPU server and each virtual server having its own host-based firewall running on them. This would make up 20 firewalls using the same resources that the 20 virtual machines are using. This defeats the purpose of virtualization, which is to apply those resources to virtual servers not security applications. Deploying security centrally within the virtual environment is in a sense one firewall versus 20 firewalls.
Hearts of Iron is a 2002 grand strategy video game developed by Paradox Development Studio and originally published by Strategy First for Microsoft Windows. A Mac OS X version was released by Virtual Programming the following year. In 2004, Atari SA published Hearts of Iron: Platinum, an updated version that sought to improve several aspects of the game. Hearts of Iron allows the player to take control of a nation in the world and guide it through World War II and the years immediately before and after it. Hearts of Iron is the first game in the eponymous series of grand strategy wargames. Despite receiving mixed reviews from critics, Hearts of Iron was followed by three additional games: Hearts of Iron II, Hearts of Iron III, and Hearts of Iron IV.
Virtual XI (pronounced "Virtual Eleven") is the eleventh studio album by English heavy metal band Iron Maiden, released on 23 March 1998. It is the band's second and final album with Blaze Bayley on vocals, as well as the final album as a five piece, as Bruce Dickinson and Adrian Smith would later return to the band, while Janick Gers who replaced Smith remained in the band. It also marks the first album to utilise a slightly modified logo, with the letters R, M, and N the same size as the other letters as opposed to them being extended. The band used the updated version of their logo for their next few albums; it was used until The Final Frontier, released in 2010.
Before the 1921 destruction of Tulsa’s Greenwood District, Black residents had created a remarkable center of business and community life. The district included stores, professional offices, entertainment venues and homes owned by Black citizens. Understanding Greenwood means learning what was built—not only what was burned.
