Virt-install: ERROR Host does not support any virtualization options.

Hello guys!

First of all sorry about my english.

I am using KVM to virtualizate. But when i run the "virt-install" command, it shows the next error:

Code:

ERROR Host does not support any virtualization options.

My server had virtualisation extensions enabled in the bios.

It is my first time using it, so i don´t know too much.
Can you help me?

Thanks in advance!

Your CPU also needs to support virtualization technology.

Does the following command generate any output:

Code:

egrep -m 1 "svm|vmx" /proc/cpuinfo

svm -> AMD CPU capable of virtualization.
vmx -> Intel CPU capable of virtualization.

Here's a link about this: Linux: Find Out If CPU Support Intel VT and AMD-V Virtualization Support

You Intel CPU does support virtualization (vmx flag is found).

Assuming that the BIOS is correctly set, can you give us a more information?

- Is this an out-of-the-box/normal KVM installation?
- Which host is used?
- Which guest are you trying to install?
- How did you run the virt-intall command (which options etc)?

First of all sorry about my answer but this is the first time i try kvm so i do not know a lot of things.

I have a Red Hat Enterprise Linux Server 6.4 x64 installed. I am using the local RHEL CD/DVD-ROM as my yum repository.
I use this commands:

Code:

# yum install kvm

That looks correct. You might want to install virt-viewer as well.

Have a look at this link: CentOS / Redhat: Install KVM Virtualization Software

BTW: Do check if the correct KVM module are loaded:

Code:

lsmod | grep kvm

You use an Intel CPU, so the output should read:

Code:

kvm_intel    <some_number>  <some_number>

kvm          <some_number>  <some_number>  kvm_intel

I'm not sure about the virt-install command. I usually use something like this (split ovre multiple lines for readability):

Code:

virt-install \

  --name      UbuntuServer \

  --ram        2048 \

  --vcpus      2 \

  --os-type    linux \

  --disk      path=/var/lib/libvirt/images/guest.img,size=16 \

  --cdrom      /dev/cdrom

- About the green entry: Substitute 16 for the size in Gb's you want/need.
- About the blue entry: /dev/cdrom assumes a real cdrom player, if you want to use an image stored on your hd use something like this: --cdrom /path/to/iso

You can also run virt-install --prompt for an interactive install.

If the above doesn't work can you post the exact error message(s) that are produced?

That must be the problem.

Try running:

Code:

# modprobe kvm

Check to see if the module is now available using the lsmod command given earlier.

after you enable VT in BIOs, you have to do a full powercycle of the host, otherwise VT doesn't not really get enabled, even if the bios says it is.

It was always enabled in the bios, it was not disabled. Anyway, i did a reboot.
Thanks!

The kvm_intel module is still missing.

I just noticed this:

Did you mix and match RHEL/CentOS versions 5 and 6? You cannot upgrade from version 5 to version 6! A fresh install is needed in that case.

This might be the reason why things don't work. Maybe you can try to remove all the kvm/qemu/libvirt related software that is installed and re-install kvm again. But if you did mix-and-match I would suggest a clean RHEL 6 (or CenOS 6) install and go from there.

Another friend uses CentOs repositories before. Can you tell me how to remove all the kvm/qemu/libvirt? I would like to try this. Otherwise i will have to reinstall RHEL.

Thanks a lot!

I would _strongly_ suggest to bite the bullet and do a fresh install. Mixing versions (5 and 6) and mixing RHEL and CentOS repo's is a very bad idea and it will give you problems along the way. These won't be limited to KVM!

That said: I was thinking of using yum to get rid of the installed packages, but now that it is confirmed that this is a mix-and-match system I'm not sure that will get rid of all the (old) packages.

And before that, i would like to tell you what i am going to do so you can confirm me.

After the installation i will set the local RHEL CD/DVD-ROM as my yum repository because the system is not registered to Red Hat Subscription Management (http://www.ehowstuff.com/how-to-setu...age-on-rhel-6/).

Then i will run the next commands:

Code:

# yum install kvm

Code:

# yum install virt-manager libvirt libvirt-python python-virtinst

After that i will try the virt-install command to see what happens and i will post here.

Is it ok?

Thanks a lot for your help. You are very kind!

Before answering your questions: Is there a specific reason why you want to use RHEL? You are already aware that you don't have access to RHN and I'm just wondering if one of the RHEL clone's would be handier.
