I had the same problem. And then I chenged the bios setting and it worked. It is the Virtual System in BIOS option which is disabled in many Intel CPUs.
have the same problem with windows10, even Virtual System in BIOS option which is enabled,
any help would be appreciated.
@Abhi07 , as this is an older post, you would have a better chance of receiving a resolution by starting a new thread. This will also be an opportunity to provide details specific to your environment that could aid others in assisting you with a more accurate answer to your question.
I tried installing using these steps:
1. Install VirtualBox. Go to to download and install VirtualBox for your computer.
2. Download the Cloudera VM. Download the Cloudera VM from The VM is over 4GB, so will take some time to download.
3. Unzip the Cloudera VM:
Right-click cloudera-quickstart-vm-5.4.2-0-virtualbox.zip and select “Extract All…”
4. Start VirtualBox.
5. Begin importing. Import the VM by going to File -> Import Appliance
6. Click the Folder icon.
7. Select the cloudera-quickstart-vm-5.4.2-0-virtualbox.ovf from the Folder where you unzipped the VirtualBox VM and click Open.
8. Click Next to proceed.
9. Click Import.
10. The virtual machine image will be imported. This can take several minutes.
11. Launch Cloudera VM. When the importing is finished, the quickstart-vm-5.4.2-0 VM will appear on the left in the VirtualBox window. Select it and click the Start button to launch the VM.
After clicking on start button to launch the VM I am getting this error:
Failed to open a session for the virtual machine cloudera-quickstart-vm-5.4.2-0-virtualbox
I have also checked the vt-x plugin through Intel(R) Processor Identification Utility application and it says it is enabled.
I don't know what else could be an issue
@shr, In order for you to find an answer faster, can you provide some further details on your system?
Also can you provide how much of those you have allocated to the VM?
I have used both the VMWare and VirtualBox versions of the VM on Windows. Occasionally I have seen a student have some trouble getting it working. In Windows machines, it is usually because they have not enabled virtualization in the BIOS. If you have taken care of that, and your host OS is 64 bit, and you have 8GB of RAM, the default settings should be okay - I usually do not modify the defaults.
If you go to this link, you can download the latest version of the Cloudera Quickstart VM (5.5.0): http://www.cloudera.com/downloads/quickstart_vms/5-5.html (The instructions you posted indicate an older version of CDH, best to use the latest.) I am currently using Virtual Box version: 5.0.14 r105127 with CDH 5.5.0.
After you download, compute the SHA1 of the zip file. SHA1 for VirtualBox file is: 4f5a5f9719f5932bc94a15b77662455917d826d1
If your computed SHA1 matches the above, the download was successful. If it doesn't match, download it again (I have seen this be a problem, but pretty rare). To unzip, it is important to use 7zip (http://www.7-zip.org/).
One other problem I've run into relates to KVM. Do you have KVM installed on your machine? If you do have KVM, then download the KVM version of Quickstart VM and don't use Virtual Box. (I haven't tested this recently, but there was a time when VB wouldn't run while KVM modules were loaded. There's a work-around that involves unloading KVM kernel modules, but I would just use the KVM version in this case.)
The problem is the very old "VT-x is disabled in the BIOS"
I thought this is taken care of after cheking it with this application:
"Intel(R) Processor Identification Utility" which i guess is bogus ;)
Thanks anyway for your support I will get the VT-x enabled and let you know if it works! :)
I had the same issue, but my VT-X settings are fine from the start also no hyper-v issues. But still cloudera VM was unable to launch. Finally below trick worked out..
once I modified "vmci0.present " setting to "False" in cloudera-quickstart-vm-5.10.0-0-vmware.vmx VM started working fine. give a try..
vmci0.present = "FALSE"
