#7230 obsolete Cannot connect Harmony 700 remote control via USB Glenn Coombs
Description

I am using VirtualBox version 3.2.6 (r63112) on Ubuntu 10.04. My guest OS is Windows XP SP3. I am trying to get the guest OS to see the Harmony remote control. When I plug it in I can see an entry for it under the "Devices=>USB Devices" menu as "Harmony Remote 0-2.5.0 [1066]" but when I select that I get an error dialog box saying:

Failed to attach the USB device Harmony Remote 0-2.5.0 [1066] to the virtual machine Win-XP. Failed to create a proxy device for the USB device. (Error: VERR_READ_ERROR).

The relevant line from the VBox log is this:

00:03:40.227 ERROR [COM]: aRC=NS_ERROR_FAILURE (0x80004005) aIID={6375231a-c17c-464b-92cb-ae9e128d71c3} aComponent={Console} aText={Failed to create a proxy device for the USB device. (Error: VERR_READ_ERROR)} aWarning=false, preserve=false

I would add that this is not a problem with USB in general as I can successfully access a Patriot USB memory stick. I only get this error with the Harmony remote control device.

#9768 worksforme Cannot connect to VM with RDP client after VirtualBox upgrade Peter Walter
Description

Host computer: x86 server running SME 8.0b7, a Centos 5 / Red Hat derivative Linux distro, VirtualBox 4.1.4, and Oracle_VM_VirtualBox_Extension_Pack-4.1.4-74291.vbox-extpack.

[root@lucas ~]# uname -r 2.6.18-274.3.1.el5

[root@lucas ~]# uname -m i686

Virtual machine: x86 server running SME 8.0b7, a Centos 5 / Red Hat derivative Linux distro.

My setup was originally working properly with virtualbox 4.1.2 and Oracle_VM_VirtualBox_Extension_Pack-4.1.2-73507.vbox-extpack installed. The problem surfaced once I upgraded VirtualBox and the extension pack to 4.1.4.

The VM apparently starts normally. However, I cannot connect with an external RDP client.

I have checked and rechecked my installation, extension pack, config.php, the VM settings, etc., all with no luck.

All installs were as root. Execution of VirtualBox is as root from rc7.d , as follows: cp /etc/rc5.d/S20vboxdrv /etc/rc7.d/. cp /etc/rc5.d/S35vboxballoonctrl-service /etc/rc7.d/. cp /etc/rc5.d/S35vboxweb-service /etc/rc7.d/.

Contents of vbox.cfg: VBOXWEB_USER='root' VBOXWEB_HOST=127.0.0.1 VBOXWEB_PORT=18083

relevant config.php settings:

  • Username / Password for system user that runs VirtualBox */

var $username = 'vbox'; var $password = 'pass';

/* SOAP URL of vboxwebsrv (not phpVirtualBox's URL) */ var $location = 'http://127.0.0.1:18083/';

Disable authentication var $noAuth = true;

/* Enable advanced configuration items (normally hidden in the VirtualBox GUI)

  • Note that some of these items may not be translated to languages other than $ */

var $enableAdvancedConfig = true;

Authentication library. var $authLib = 'Builtin';

websrvauthlibrary setting: vboxmanage setproperty websrvauthlibrary null

It seems that the VDRE server isn't running.

[root@lucas ~]# VBoxHeadless -s myvmname Oracle VM VirtualBox Headless Interface 4.1.4 (C) 2008-2011 Oracle Corporation All rights reserved.

VRDE server failed to start. VRDE server is inactive.

How can I determine why the VDRE server isn't running?

#5927 obsolete Cannot connect to freenx server running on host and guest simultaneously. Port report reported as already open by the connecting client. Brandon
Description

Software Configuration Description


We have a Ubuntu 64bit 9.10 server:
Linux sc-vm01-lnx.Stonegate 2.6.31-16-generic #53-Ubuntu SMP Tue Dec 8 04:02:15 UTC 2009 x86_64 GNU/Linux

  • This server is using freenx to allow remote graphical sessions.
  • The server has a static ip address and is utilizing one NIC:

eth0 Link encap:Ethernet HWaddr 00:1d:09:29:32:5f inet addr:172.27.0.204 Bcast:172.27.3.255 Mask:255.255.252.0

07:00.0 Ethernet controller: Broadcom Corporation NetXtreme II BCM5708 Gigabit Ethernet (rev 12)

Our Guest VM is Ubuntu 64bit 9.10 desktop:
Linux sgintel.stonegate 2.6.31-17-generic #54-Ubuntu SMP Thu Dec 10 17:01:44 UTC 2009 x86_64 GNU/Linux

  • The guest uses Network Adapter 1:as the VirtualBox Intel PRO/1000 MT Desktop (Bridged adapter, eth0)
  • The guest has a static IP:

eth0 Link encap:Ethernet HWaddr 08:00:27:f2:5d:ca inet addr:172.27.0.206 Bcast:172.27.3.255 Mask:255.255.252.0

  • The guest is running freenx server to provide graphical remote sessions.
  • VirtualBox Guest Additions are installed at the appropriate version.

Problem Description


I can successfully connect to either the Host or the Guest using the NX Client but not both at the same time.

When I try to connect to both at the same time, I get an error telling me that TCP Port 11000 is already in use.

I have no trouble using NX Client from my computer to connect to two freenx servers simultaneously if they are on separate physical computers. Therefore, there must be an issue with the way VirtualBox 3.1.2 r56127 is handling network routing dealing with the ports.
The host with 172.27.0.204 has port 11000 open when a client is connected via NX Client.
The guest with 172.27.0.206 has port 11000 open when a client is connected via NX Client.

I have difficulty imagining any other cause or conclusion. I appreciate you and your time considering how to resolve this issue.
