#11101 obsolete All Guests VERY slow on Ubuntu 12.04 64-bit Host (seen in Virtualbox 4.2 and 4.1) Lachesis
Description

I've had extreme slowness on a variety of VirtualBox guests in several versions (at least 4.2 and 4.1) on my Ubuntu 12.04 (also seen on 11.10) server in VBoxHeadless. It's so slow that even booting Arch Linux (guest) takes more than ten minutes (instead of 30 seconds normally). I've got plenty of RAM (8GB of 12GB free right now). The weirdest thing is that restarting the host seems to fix it for a few hours or days. Nothing else helps, not even unloading and reloading all the modules.

Currently running VirtualBox version: 4.2.0_OSEr43316

Host: Linux tron 3.2.0-23-generic #36-Ubuntu SMP Tue Apr 10 20:39:51 UTC 2012 x86_64 x86_64 x86_64 GNU/Linux

Host dmesg and Arch Linux Guest 32-bit and 64-bit logs attached. I've seen the problem in Windows Server 2008 as well.

#4589 obsolete usbfilters details Lacsap
Description

Hi,

I'm using VirtualBox 3.0.2 PUEL edition on a GNU/Linux host : everything works perfectly. My system is on a usb stick and this system stick appears in the list of available usb devices for guests.

If, by mistake, instead of choosing the correct usb device freshly inserted, I check my stick in the list, I freeze the system !

The documentation says """The usbfilter commands are used for working with ... global filters which affect the whole VirtualBox setup. Global filters are applied before 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.""".

I tried this : VBoxManage usbfilter add 0 --target global --action ignore --vendorid 1234 --productid 1234 --serialnumber 123456789012. But this has no effect: my stick still appears in the list and so, can be captured. Note that serial number is not returned by the command VBoxManage list usbfilters.

Thanks for VirtualBox.
