#14894 worksforme Constant ARP requests Horizon_Brave
Description

Hello

I'm using a Debian distro in Windows 10, through Virtualbox. I have a NAT network, as I just need some basic functionality for now. This really isn't a problem, but more of a curiosity. I'm running a background tcpdump and I notice anytime Debian needs to make a request 'outside" (sent to 10.0.2.2 my default virtual router), I see that an ARP request for the MAC of 10.0.2.2 has to be sent. Even a ping, a traceroute, any NTP requests, etc... they all force debian to ARP out a request for the MAC. Here's a sample:

15:44:27.964752 ARP, Request who-has 10.0.2.2 tell 10.0.2.15, length 28
15:44:27.965098 ARP, Reply 10.0.2.2 is-at 52:54:00:12:35:02 (oui Unknown), length 46

This plays out each and every time Debby, needs to contact something through it's default gw. Is this expected? I checked my arp cache and it has the entry for the 10.0.2.2 gateway with it's matching MAC address.

The OUI unknown message is what's bothering me that there may be an issue with it trying to use the entry into the arp table? Any idea's?

#11149 duplicate Constant disk read gaborca
Description

I have got a relatively old harddrive in my PC, and recently I noticed that it keeps constant disk reading (or writing) when I run particular programs, because it has got audible seek sounds. After investigating a bit (stopping all my software, and starting them one by one) it turned out that VirtualBox is making that noise.

To prove it, I downloaded and ran ProcMon from Microsoft (http://technet.microsoft.com/en-us/sysinternals/bb896645.aspx), chose Filter (ctrl+L), and added two rules: "Operation is ReadFile" and "Operation is WriteFile". VBoxSVC.exe and VirtualBox.exe make together about 300 disk reads in the ProcMon process reading refresh period (in 2 or 3 seconds). The weird thing is that both processes keep reading the same file, C:\Program Files\Oracle\VirtualBox\VBoxC.dll, about 100-200 bytes, and they start it over and over again. You can see that on the attached screenshot of ProcMon, and I also upload that onto my website.

My host is: Windows XP SP3 This bug is present in 4.2.0 and also in 4.2.4 (the newest one) The bug is present in all guest I started (Windows XP, Debian, OpenBSD) The bug doesn't generate visible CPU load, but I fear it wears the disk

#6252 fixed Constant freezes of VirtualBox guest grof
Description

Hi,
on Windows XP SP3 host I am using VirtualBox 3.1.4 and running guest Ubuntu 9.10.

When guest is started VirtualBox is using about 4% CPU. And at some stage guest freezes (I know this because music player inside guest stops playing and any click on any window does not produce any response). When I switch back to host I see 35-40% of CPU is being used by VirtualBox process. The only way I can solve the problem is to power-down guest.

I attached log file from this computer.

P.S. The same problem I have on Ubuntu 8.04 LTS host and Windows XP guest running VirtualBox 3.1.2 in headless mode, but on this computer guest freezes one's per two to three days, but always when some minor task is done.

I never experienced such a problem using VBox pre 3.1 release.

On forum http://forums.virtualbox.org/viewtopic.php?f=1&t=28174 sandervl said I should report a bug.
Regards
