Do you want your VMs to be directly accessible to the rest of your LAN, with an IP from the same subnet as your host OS? If so, what you want to do is set your guest networking to "bridged" and select eth1. However, this usually only works on wired interfaces, as wireless doesn't usually respond well to being told to transmit two different MAC addresses. It depends on the wireless hardware you are using. If you do try to do that, don't do anything that I recommend in this post - just make it a bridged interface on eth1. If it doesn't work, it probably won't. See the VirtualBox <a href="http://www.virtualbox.org/wiki/End-user_documentation" rel="nofollow">documentation</a>. Hi Abe,

I checked the firewall on the guest system: the service is not even installed. What should I do now? =) Thank you for your patience. Hi Tyler, thank you for your reply.

My design intentionally leaves the guest behind a NAT layer, where my host can access it but nothing else. From your results ("I obtain the exact same result if I select 'bridged connection' and I link it to my 'eth1' wireless interface.Guest ping host, host can’t ping guest."), I think the problem is more likely the Windows firewall in the guest. Hi Abe,

From your results (“I obtain the exact same result if I select ‘bridged connection’ and I link it to my ‘eth1′ wireless interface.Guest ping host, host can’t ping guest.”), I think the problem is more likely the Windows firewall in the guest.

Go to System Settings -> Input Actions. 2. Click Edit -> New -> Global Shortcut -> D-Bus Command. 3. Set a name for this action, assign the trigger to the "Sleep" button. 4. Set the D-Bus action to: Remote application: org.freedesktop.PowerManagement Remote object: /org/freedesktop/PowerManagement Function: org.freedesktop.PowerManagement.Suspend Arguments: Save and test.

2. Click Edit -> New -> Global Shortcut -> D-Bus Command.
3. Set a name for this action, assign the trigger to the “Sleep” button.
4. Set the D-Bus action to:

Remote application: org.freedesktop.PowerManagement

Sorry for my English. My problem is as follows: I'm on Ubuntu 9.10 with VirtualBox 3.1.4, trying to get a virtualized Windows XP visible from the rest of my network. I followed your guide step-by-step. The only difference is I selected "bridged" instead of "host-only". Is this correct? (my VM interface is bridged to "vnet0") However, the only thing I obtain is XP being able to reach the network, not vice versa. I obtain the exact same result if I select "bridged connection" and I link it to my "eth1" wireless interface. Guest ping host, host can't ping guest. What I'm missing? Is there something in Ubuntu 9.10 that block traffic somewhere? Thank you very much in advance! Hi everybody, thank you for this How-to.

]]> Comment on Poor VirtualBox guest performance with Intel VT-X on Ubuntu 9.10 by IceTNet http://www.tolaris.com/2009/11/04/poor-virtualbox-guest-performance-with-intel-vt-x/comment-page-1/#comment-145 IceTNet Tue, 16 Feb 2010 14:51:31 +0000 http://www.tolaris.com/?p=590#comment-145 Boom! Thanks. I was on the 32-bit architecture prior to 9.04 which is when I switched to 64-bit. I have been having issues with VirtualBox since. I could almost swear that it was related to the USB implementation, however, the issues were completely intermittent. I didn't even think about the VT-x stuff, I mean It's tested hardware right... Thanks, I disabled VT-x and the VM flies again. There is something with USB and VT-x, though. In my tests, copying 9GB of information to an NTFS thumb drive, Karmic would consistently pause every application (only when a VM was running) and my transfer rate for USB2.0 would drop down to mere 400kbps. Now that I've disabled VT-x, no problems yet. Thanks again. Boom!
