Genymotion on Ubuntu 13.04 won't connect to virtual device

Question

I'm running Ubuntu 13.04. I've installed VirtualBox 4.3.6 and Genymotion 2.0.3. After installation, I downloaded the Galaxy S4 - 4.2.2 image, as well as a few others. All of them encounter the same problem: After clicking Play, I get the window for the virtual device, but then I get an error:

Unable to connect to your virtual device! Genymotion will now stop. Check your VirtualBox network configuration.

The VirtualBox network is configured like this:

No NAT networks
One Host-only Network, vboxnet0
- Adapter
  - IPv4 Address: 192.168.56.1
  - IPv4 Network Mask: 255.255.255.0
  - IPv6 Address: fe80:0000:0000:0000:0800:27ff:fe00:0000
  - IPv6 Network Mask Length: 64
- DHCP Server
  - Server Address: 192.168.56.1
  - Server Mask: 255.255.255.0
  - Lower Address Bound: 192.168.56.100
  - Upper Address Bound: 192.168.56.254

After hitting Play, I look in the genymotion-player.log and see the following related to networking:

Jan 10 00:51:12 [Genymotion Player] [Debug] "Name:            vboxnet0

...and, a bit later in the log:

upperIPAddress: 10.0.2.254
Enabled:        Yes

Still later in the log:

Jan 10 00:51:13 [Genymotion Player] [Debug] Virtual Machine started. 
Jan 10 00:51:13 [Genymotion Player] [Debug] Waiting for an IP address...

A couple of seconds later:

Jan 10 00:51:18 [Genymotion Player] [Debug] Genymotion system started. Attributed IP address:  "192.168.56.3"

And then, when it fails:

Jan 10 00:51:24 [Genymotion Player] [Error] Unable to connect player to virtual machine: "192.168.56.3"

I've tried other workarounds suggested:

Uninstall / reinstall Genymotion
Uninstall / reinstall VirtualBox
Downgrade VirtualBox to 4.2
Delete and redownload the device images
Delete and allow Genymotion to recreate the host-only network

I also should state that I do not have a firewall, so I'm confident there's no issue arising because of interference.

Turns out the problem was that I'm running both VMWare and, to support Genymotion, VirtualBox.

I discovered this with help from the Genymotion support, who pointed out that when I run:

sudo netstat -nm

the result is something like:

Kernel IP routing table
Destination     Gateway         Genmask         Flags   MSS Window  irtt Iface
0.0.0.0         192.168.100.2   0.0.0.0         UG        0 0          0 eth0
169.254.0.0     0.0.0.0         255.255.0.0     U         0 0          0 eth0
172.16.30.0     0.0.0.0         255.255.255.0   U         0 0          0 vmnet1
192.168.56.0    0.0.0.0         255.255.255.0   U         0 0          0 vmnet8
192.168.56.0    0.0.0.0         255.255.255.0   U         0 0          0 vboxnet0
192.168.100.0   0.0.0.0         255.255.255.0   U         0 0          0 eth0

I was able to fix this by going into VirtualBox, and from the Network section of the Preferences dialog, I changed every reference to 192.168.56.* in the vboxnet0 configuration to 192.168.57.*.

THANK YOU Genymotion support team!
