Virtualbox sata SATA controller, enumerated second in the virtual machine, is where disk files should be placed. VirtualBox logo since WindowsmacOSLinux and Solaris [1]. Wikimedia Commons has media related to VirtualBox. Windows XP ships with drivers for neither. As the virtual machine will most probably expect to see a hard disk built into its virtual computer, VirtualBox must be virtualbox sata to present "real" storage to the guest as a virtual hard disk.

The end result is the same as before. Virtualbox sata major OSes support these devices for a long time and ship generic drivers making third-party drivers superfluous.

Differencing images can be chained. If another differencing image is created for a virtual disk that already has a differencing image, then it becomes a "grandchild" of virtualbox sata original parent.

The first differencing image then becomes read-only as well, and write operations only go to the second-level differencing image. When reading from the virtual disk, VirtualBox needs to look into the second differencing image first, then into the first if the sector was not virtualbox sata, and then into the original image. There can be an unlimited number of differencing images, and each image can have more than one child.

Traditionally, Oracle VM VirtualBox has opened disk image files as normal files, which results in them being cached by the host OS like any other file. The main advantage of this is speed: when the guest OS writes to disk and the host OS cache uses delayed writing, the write operation can be reported as completed to the guest OS quickly while the host OS can perform the operation asynchronously. Also, when you virtualbox sata a VM a second time and have enough memory available for the OS to use for caching, large virtualbox sata of the virtual disk may be in system memory, and the VM can access the data much faster.

Note that this applies only to image files. Buffering does not occur for virtual disks residing on remote iSCSI storage, which is the more common scenario in enterprise-class setups. While buffering is a useful default setting for virtualizing a few machines on a desktop computer, there are some virtualbox sata to this approach:. Delayed writing through the host OS cache is less secure. When the guest OS writes data, it considers the data written even though it has not yet arrived on a physical disk. If for some reason the write does not happen, such as power failure or host crash, the likelihood of data loss increases.

Disk image files tend to be very large. Caching them can therefore quickly use up virtualbox sata entire host OS cache.
