Virtual Box е програма, с чиято помощ можете да виртуализирате и ползвате различни операционни системи като: Windows NT 4.0, 2000, XP, 2003 Server, Vista, DOS/Windows 3.x, Linux и OpenBSD. Създадените от вас виртуални машини не отстъпват по нищо на реалните. Характерно за VirtualBox е лесната инсталация, манипулация и удобния графичен интерфейс.
VirtualBox създава виртуална среда, в която може да инсталирате различни операционни системи, да инсталирате и тествате програми или с други думи може да правите почти всичко, което правите в нормалната ви ОС, без да се притеснявате, че може да повредите нещо. VirtualBox не разполага с всички възможности на подобните на нея програми, но за сметка на това разполага с такива, които не се срещат при нейните конкуренти, като стартиране на виртуалната машина отдалечено чрез Remote Desktop Protocol (RDP) и поддръжка на iSCSI.
Промени :
VMM: fixed 64-bit guests on AMD Fusion CPUs (bug #8824)
VMM: fixed handling of the sysenter/sysexit machine instructions in 64-bit guests on Intel hosts
GUI: added linked clone support
GUI: fixed error check when changing the VM controller settings (4.1.0 regression; bug #9246)
GUI: fixed the inclusion of additional information (license, vendor, ...) on OVF export
GUI: when taking a snapshot from the VM selector, don't do a live snapshot
GUI: fixed immediate crash during start on certain environments due to a library version conflict
Guest control execution: implemented copying single files from guest to the host (directories and filters not supported yet)
Guest control execution: limited to serve up to 5 guest processes at a time by default
Main: return the correct RDP default port fixing settings warnings in the GUI if the remote display was enabled at runtime (bug #9368)
VBoxSVC: made the path comparison OS independent when images are registered (bug #9303)
VBoxSVC: several fixes/performance improvements for cloning of VMs
Snapshots: fixed "Solid-State drive" flag survival on snapshot creation (bug #9379)
VBoxManage: implemented copyfrom and stat guest control tools to copy files from guest to host and to check for existence of files on the guest
VBoxManage: fixed extpack install --replace (bug #9308)
VBoxManage: allow to start multiple VMs with startvm
VBoxManage: experimental support for SATA CD/DVD hotplugging
Mouse support: fixed an off-by-one pointer position error affecting Windows guests (bugs #7566, #9321)
VRDP: fixed a case when the screen was not redrawn correctly (bug #9242)
NAT: changed TCP connection establishment according to Winsock API requirements (Windows hosts only; bug #8919)
USB: fixed device recognition issues (bugs #9299) and fixed several device capturing issues (Windows hosts; bug #9299)
USB: fixed issues with remote filters being applied to local USB devices
OVA: fixed import of renamed OVA files (bug #9033)
Windows host: fixed icon for .VDI files (bug #9393)
Solaris hosts: fixed a bug preventing parallel usage of multiple host NICs with Crossbow based bridged networking
Linux hosts: fixed random kernel panics on host suspend / shutdown (4.1.0 regression; bug #9305)
Guest Additions: keep logged in user count in out-of-memory situations and warn about it
Solaris Additions: fixed shared folders due to missing symbols in the vboxfs module (4.0.12 / 4.1.0 regression; bug #9264)
Windows Additions: fixed file truncation on a shared folder with some applications (bugs #9276, #9315)
Windows Additions: fixed shared folder issues with antivirus software and 64 bit Windows guests (bug #9318)
Windows Vista and 7 guests: WDDM driver fixes and performance enhancements, fixed WinSAT crashes (#9267)
Linux Additions: fixed llseek() for Linux kernels 2.6.37 and above
Изисквания :
In order to run VirtualBox on your machine, you need:
Reasonably powerful x86 hardware. Any recent Intel or AMD processor should do.
Memory. Depending on what guest operating systems you want to run, you will need at least 512 MB of RAM (but probably more, and the more the better). Basically, you will need whatever your host operating system needs to run comfortably, plus the amount that the guest operating system needs. So, if you want to run Windows XP on Windows XP, you probably won't enjoy the experience much with less than 1 GB of RAM. If you want to try out Windows Vista in a guest, it will refuse to install if it is given less than 512 MB RAM, so you'll need that for the guest alone, plus the memory your operating system normally needs.
Hard disk space. While VirtualBox itself is very lean (a typical installation will only need about 30 MB of hard disk space), the virtual machines will require fairly huge files on disk to represent their own hard disk storage. So, to install Windows XP, for example, you will need a file that will easily grow to several GB in size.
A supported host operating system. Presently, we support Windows (XP and later), many Linux distributions, Mac OS X, Solaris and OpenSolaris.
A supported guest operating system. Besides the user manual (see below), up-to-date information is available at "Status: Guest OSes".
