No network access from Centos 6.5

[sej222]

@Perryg - Yes, it is still NAT. I'm following you since you're the expert. Got nothing from that command:
C:\Program Files\Oracle\VirtualBox>VBoxManage.exe list natnets

C:\Program Files\Oracle\VirtualBox>

[Perryg]

It appears that something is not installed. I would try removing this version and installing version 4.3.12 and see if it all sorts itself out.
http://download.virtualbox.org/virtualbox/4.3.12/

@Perryg - This is getting worse ...
I uninstalled 4.3.14 but the uninstall failed. It still showed on the list of programs. I pressed on and installed 4.3.12. Installed centos on a new VM. After the packages are installed, a dialog comes up saying to reboot. I clicked the reboot button and got a popup:
Oracle VM VirtualBox Manager has stopped working
A problem caused the program to stop working correctly. Windows will close the program and notify you if a solution is available. [close program button] I clicked the button.
Oracle VM VirtualBox Manager window is still there with a cursor busy icon for a long time, then stops. Centos6.5a shows on the left panel, labled "Aborted". VMManager appears normal. I pressed on and the centos seemed OK, but when I leave it, I get the same popup.

I tried to get to a completely clean environment to start fresh again. I uninstalled 4.3.12, which also gave me errors. By running uninstall multiple times on each, eventually all trace of both versions was gone. btw, I also deleted all the vms. I found some files in .Virtualbox in the home directory and deleted those. Nothing in the Program Files directory. I even checked regedit. Nothing. So I did a clean install of 4.3.12 and got the same popup in the same place. So I'm stuck.

[Perryg]

Doesn't sound good at all. This usually means the host OS has something wrong.
Can you post the VBoxsvc.log? Should be in the same place as the VirtualBox.xml.
Also this popup said it would give you some more information, did it and what was it exactly?

[sej222]

Popup did not give any more info.
Here's the log:

[Perryg]

It's looking for the extension pack that matches the installed version. Have you installed it? You should be able to boot it though if you disable USB2 in the guest settings.

[sej222]

No, I was just marching through the startup wizard. This was the initial install.

[sej222]

hmm, USB 2.0 is not enabled. Should I disable USB altogether?

[sej222]

@Perryg, any other suggestions?

[Perryg]

Like I said earlier the situation you have sounds like a host issue. Maybe someone that actually uses Windows as host ( I haven't for years ) can see something else to have you try.

[popx2004]

Anyone who finds this and is still running into the same problem I managed to fix it by editing

/etc/sysconfig/network-scripts/ifcfg-eth0: to

DEVICE=eth0
BOOTPROTO=dhcp
ONBOOT=yes

[loukingjr]

fwiw, when I installed CentOS 7 the first time I had no access. It turned out I had to set the network while installing.

Thanks popx2004, you save my time!!!

Thank you popx! It worked also on Red Hat 6.5 on Linux host.

Hi friends,

You can use NAT adapter in VM Box.
All You need to do is turn off the firewall in CentOS!
Just go to terminal and type:
systemctl disable firewalld

Then You can check the status of firewall by a command:
systemctl status firewalld

Now You may use FireFox in Your CentOS.
You may also want to stop Firewall but it is not neccessary if it is already disabled in CentOS:
systemctl stop firewalld

It works on Centos 6 and 7 too.
