Para que servem as opçoes de filtro de dispositivo USB no VirtualBox?
http://download.virtualbox.org/virtualbox/3.2.4/UserManual.pdf8.24 VBoxManage usbfilter add/modify/removeThe usbfilter commands are used for working with USB filters in virtual machines,
or global filters which affect the whole VirtualBox setup. Global filters are applied be-
fore machine-specific filters, and may be used to prevent devices from being captured
by any virtual machine. Global filters are always applied in a particular order, and only
the first filter which fits a device is applied. So for example, if the first global filter says
to hold (make available) a particular Kingston memory stick device and the second to
ignore all Kingston devices, that memory stick will be available to any machine with
an appropriate filter, but no other Kingston device will.
When creating a USB filter using usbfilter add, you must supply three or four
mandatory parameters. The index specifies the position in the list at which the filter
should be placed. If there is already a filter at that position, then it and the following
ones will be shifted back one place. Otherwise the new filter will be added onto the
end of the list. The target parameter selects the virtual machine that the filter should
be attached to or use “global” to apply it to all virtual machines. name is a name for
the new filter and for global filters, action says whether to allow machines access to
devices that fit the filter description (“hold”) or not to give them access (“ignore”). In
addition, you should specify parameters to filter by. You can find the parameters for
devices attached to your system using VBoxManage list usbhost. Finally, you can
specify whether the filter should be active, and for local filters, whether they are for
local devices, remote (over an RDP connection) or either.
When you modify a USB filter using usbfilter modify, you must specify the filter
by index (see the output of VBoxManage list usbfilters to find global filter in-
dexes and that of VBoxManage showvminfo to find indexes for individual machines)
and by target, which is either a virtual machine or “global”. The properties which can
be changed are the same as for usbfilter add. To remove a filter, use usbfilter
remove and specify the index and the target.
e para que serve a opção de habilitar até 8 monitores virtuais ?
http://download.virtualbox.org/virtualbox/3.2.4/UserManual.pdf7.1.8 Multiple remote monitorsTo access two or more VM remote displays you have to enable the VRDP multiconnec-
tion mode (see chapter 7.1.7, Multiple VRDP connections, page 116).
The RDP client can select the virtual monitor number to connect to using the
domain logon parameter (-d). If the parameter ends with @ followed by a number,
the VirtualBox RDP server interprets this number as the screen index. The primary
guest screen is selected with @1, the first secondary screen is @2, etc.
The MS RDP6 client does not let you specify a separate domain name. Instead,
use domain\username in the Username: field – for example, @2\name. name must be
supplied, and must be the name used to log in if the VRDP server is set up to require
credentials. If it is not, you may use any text as the username.
