#4377 fixed guest hangs on IO operations Costin Grigoras
Description

I cannot reproduce the problem but it seems to be related to IO, most probably network. At some point after a few hours of working the guest hangs almost completely. It still answers to ping for example and if I have a console opened I can still type a few commands. But once something requires some IO, it hangs. For example, direct login on tty accepts u/p then says: "Login timed out after 60 seconds". I managed only to see the list of processes in D (hundreds of them) and for example strace on an httpd instance shows it blocked in accept(...

There is nothing in dmesg on either the guest or the host. VBox.log is also clean. This exact configuration worked fine until ver 3.0.0, so it looks like a bug in the latest version. Apparently it doesn't depend on any hardware virtualization features since it showed even in 2 CPUs with all the options enabled and 1 CPU with none of the options.

I'll try downgrading to 2.2.4 to see if it solves the problems, but it might take a while until I can be sure of the outcome.

#6249 duplicate guest hangs if pressing the left CTRL key several seconds, it recovers after releasing the key Mihai Hanor
Description

Host: XP SP3 32 bit, E6400 Guests: * 1st - XP SP3 32 bit, guest additions installed, 2D+3D acceleration enabled, then disabled; VT-X enabled, then disabled; NX enabled, then disabled; network bridged on, then off; usb off; audio null, then off; even with all of them off * 2nd - Windows 7 Ultimate 64 bit, no guest additions, 2D+3D acceleration off; VT-X and NX enabled; usb off; audio null; network briged on; even during its install (see log)

The host key is set to right CTRL. When pressing left CTRL, the guest freezes. If mouse integration is disabled, the guest's cursor freezes, if not, you are able to move it, but can't interract with the freezed guest. To better observe this, use the guest cursor to trigger a hovering effect inside the guest, or open a text editor and observe the blinking text cursor. The guest recovers only when releasing the left CTRL key.

#1024 fixed guest freezes with ehci enabled Benjamin Kay
Description

The guest is Windows XP Professional and the host is Ubuntu Gutsy 7.10 on an x86_64 processor with VT-x. VirtualBox 1.5.4 introduces ehci emulation (thank you!), but with the "Enable USB EHCI Controller" boxed checked, the guest freezes whenever a USB device is captured.

After starting the virtual machine, but before capturing a USB 2.0 flash drive:

When I try to capture the USB 2.0 flash drive, the guest freezes. There is no blue screen, it simply becomes unresponsive. VirtualBox itself does not freeze. The log indicates:

The guest still freezes if VT-x is disabled.


With the "Enable USB EHCI Controller" box unchecked it is possible to capture and use the same USB 2.0 flash drive without the guest freezing. However a similar error still appears in the log when the device is captured:

4772:25:07.222 ERROR [COM]: aRC=0x80070057 aIID={e31f3248-90dd-4ca2-95f0-6b3604$
