Dear All

I want to use KVM and I installed 23-bit Centos 5.2 on a AMD Phenom(tm) 9650 Quad-Core Processor that support Virtualization (VT). but when I boot it , I've got this message "kvm: no hardware support". Can I use KVM on a 32-bit OS??

Best Regards

Re: no hardware support

hrmb,

Yes, you can use kvm with a 32-bit host. Did you check if virtualization is switched on in your bios?

Re: kvm support

I just reread your initial post. You're running Centos 5.2 but Centos only started supporting kvm from Centos 5.4 which was released recently. You'll have to upgrade CentOS 5.4.

Re: fedora 10 64-bit

So modprobe didn't work for you on fedora 64-bit? Did you upgrade CentOS to 5.4 on your 32-bit machine?

Finally I upgrade to Centos 5.4 and the kvm is running, but when I compiled the 2.6.30.9 kernel I've got the no hardware support error when I want to boot os with this kernel, and kvm module not loaded.

I don't know how to solve this??????????

Re: finally upgrade to Centos5.4

Out of curiosity, any reason why you're running Centos 32-bit?

Try the Centos5.4 64-bit version and see if that works.
