Hola <br><br>esto encontre en un foro de centos es un extracto del manual de VirtualBox lo malo esdta en ingles pero no se ve muy dificil, yo ocupo xen, y virtual box en ubutu....<br><br>From VirtualBox manual:<br><br>11.4.6 USB not working<br>
If USB is not working on your Linux host, make sure that the current user has permission<br>to access the USB filesystem (usbfs), which VirtualBox relies on to retrieve valid<br>information about your host’s USB devices.<br>
<br>As usbfs is a virtual filesystem, a chmod on /proc/bus/usb has no effect. The<br>permissions for usbfs can therefore only be changed by editing the /etc/fstab file.<br>For example, most Linux distributions have a user group called usb or similar, of<br>
which the current user must be a member. To give all users of that group access to<br>usbfs, make sure the following line is present:<br># 85 is the USB group<br>none /proc/bus/usb usbfs devgid=85,devmode=664 0 0<br>Replace 85 with the group ID that matches your system (search /etc/group for “usb”<br>
or similar). Alternatively, if you don’t mind the security hole, give all users access to<br>USB by changing “664” to “666”.<br>The various distributions are very creative from which script the usbfs filesystem<br>is mounted. Sometimes the command is hidden in unexpected places.<br>
For SuSE 10.0 the mount command is part of the udev configuration file<br>/etc/udev/rules.d/50-udev.rules. As this distribution has no user group<br>called usb, you may e.g. use the vboxusers group which was created by the<br>
VirtualBox installer. Since group numbers are allocated dynamically, the following<br>example uses 85 as a placeholder. Modify the line containing (a linebreak has been<br>inserted to improve readability)<br>DEVPATH="/module/usbcore", ACTION=="add",<br>
RUN+="/bin/mount -t usbfs usbfs /proc/bus/usb"<br>and add the necessary options (make sure that everything is in a single line):<br>DEVPATH="/module/usbcore", ACTION=="add",<br>RUN+="/bin/mount -t usbfs usbfs /proc/bus/usb -o devgid=85,devmode=664"<br>
Debian Etch has the mount command in /etc/init.d/mountkernfs.sh. Since<br>that distribution has no group usb, it is also the easiest solution to allow all members<br>of the group vboxusers to access the USB subsystem. Modify the line<br>
domount usbfs usbdevfs /proc/bus/usb -onoexec,nosuid,nodev<br>so that it contains<br>domount usbfs usbdevfs /proc/bus/usb -onoexec,nosuid,nodev,devgid=85,devmode=664<br>As usual, replace the 85 with the actual group number which should get access to<br>
USB devices.<br>Other distributions do similar operations in scripts stored in the /etc/init.d directory.<br><br>Suerte. <br><br>Espero te ayude.<br><br>Atte.<br><br>Mario Ganga Castro.<br><br><br><br><br><div class="gmail_quote">

Monica,<br><br>Si tu objetivo es solamente crear Maquinas virtuales en tu maquina que tiene ya CentOS, entonces seria mejor que utilices Xen, el kernel de Xen y obviamente escogiendo el kernel Xen cuando GRUB te da la opcion al arranque<br>
<br>Saludos<br><br>Julio<br>________________<br><br>>Hola a todos:<br>>Tengo un pequeño problemilla con VirtualBox...<br>>instalado sobre CentOs.....<br>>Última versión de CentOS, última versión de VirtualBox.<br>
>mi problema es qeu no consigo que reconozca los USB....<br>>si alguno sabéis alguna manera....agradecería que me comentéis como va!!<br>>Ya qeu no se como
haceeeerlooooo...sniff!!<br>>Muchas gracias a todos!!<br><br></div></div></div><br>
