PostPosted: Mon Mar 10, 2014 2:24 pm    Post subject: Virtualbox killing network Reply with quote

Recently I've had an issue from time to time where I find my network completely inaccessible from any device. When this happens I find the status lights on my switches blinking rapidly in sync for all connected ports. Pinging the router fails. I've known that my Gentoo desktop is where the problem originates. When this problem occurs the system is unresponsive. I can't wake the monitors up, I can't switch to a virtual console, and I can't ssh in (unsurprising considering the state of the network.) So I reach down and push the reset button on the front of my case. The instant I push it my network springs back to life. My other systems reestablish their connections, the switches go back to normal behavior, the router becomes pingable. So something is going on with my Gentoo machine that is causing this to happen. It never happens when I'm using the machine. It will always be while I'm sleeping or at work so it seems to trigger after being idle for a while.

Recently I realized that this only seems to happen when I leave VirtualBox running with a Windows XP guest. I use this vbox installation to do some development and porting on Windows. I don't use it for any other purpose so browsing with it is very limited, I don't download much to it, and I have Microsoft Security Essentials installed and updated. I am pretty certain that there are no viruses or malware on it. Some of the development that I do requires interaction with other devices on the network and that does not work when the guest OS is behind NAT. So I have vbox configured to run the guest with a "Bridged Adapter" network configuration. This triggers the guest to obtain an IP address directly from the router through the Gentoo systems ethernet adapter. The guest appears to be a normal system connected to the network and works with the other devices in this configuration. I believe this may be part of what is causing the issue. When this feature is enabled vbox will trigger the ethernet adapter to switch to promiscuous mode:

Code:
Mar  4 22:14:38 dmwoodlx kernel: [527651.165338] device eno1 entered promiscuous mode


The last thing I usually see in /var/log/messages before the reset is a couple instances of this line:

Code:
Mar 10 07:16:12 dmwoodlx kernel: [387300.642236] hwdev DMA mask = 0x000000007fffffff, dev_addr = 0x00000000d0669000
Mar 10 07:16:12 dmwoodlx kernel: [387300.642312] hwdev DMA mask = 0x000000007fffffff, dev_addr = 0x00000000d069d000
Mar 10 07:16:12 dmwoodlx kernel: [387300.642339] hwdev DMA mask = 0x000000007fffffff, dev_addr = 0x00000000d06bd000


This does not seem to occur if I shutdown the guest OS before leaving the machine idle. Sometimes I'll be in the middle of a development task when I get up and I want to leave everything as it is. I also have not verified with certainty that this problem will not occur with vbox configured to use a NAT network configuration. I intend to leave the guest running with this configuration to see.

Any assistance is appreciated. Here is some relevant info:

I have left the XP guest running since making this thread and the issue has not occurred since. So it does seem that the issue is related to using the "Bridged Adapter" network configuration.

This happened again this morning and the guest was not configured for "Bridged Adapter". It was configured for "NAT". At this point I have no idea what is causing this to occur but it is a serious problem.

I routinely run 9 instances of Windows in Vbox. All are set the same way in the network: Bridged Adaptor with Promiscuous Mode set to Deny. Never have any problems with the network.

I did however give each Vbox a reserved address in the router because on restart of a SAVED machine, the SAVED machine holds its previous IP address which sometimes collides because the router reassigned the address to something else in the meantime.
