Environment: Dell SC1435 server with 2346HE quad-core cpu AMD-V 16GB
OS: Centos 5.2
Kernel: 2.6.18-92.1.13
Application: KVM install
Situation so far: Following the "CentOS guide to installing KVM"
Ran: grep svm /procinfo/cpuinfo to ensure that amd processor acceptable for virtualisation. Result: Passed
Ran: yum install kvm kmod-kvm Result: all installed correctly with no error messages
Ran: modprobe kvm-amd to check kvm module matches infrastructure
Result: FATAL: Error inserting kvm-amd (/lib/modules/2.6.18-92.1.13.el5/extra/kvm/kvm-amd.ko): Operation not supported

Actions taken so far: 1. Googled this error message, checked the seemingly-relevant results. None seemed to match this particular issue, and not for CentOS
2. Posted this request last night in CentOS forum, no response yet
3. Joined this forum, Searched on 'KVM' and read the many hits that resulted - again, not the same error message

My status: Complete newbie - and desperate! (all prior experience in Windows), up against deadline tomorrow

Request: Could somebody please advise me what this error message is actually saying, and the likely causes? How can one determine which operation it is that is not supported? Guidance on what to try next very much appreciated, please.

Thank you
Graham

If it's SE Linux then changing context could fix things, if the module doesn't agree with your kernel (for whatever reason) rebuilding it from source might help. Else, and without actual dmesg, log output and trace info it's hard to say what goes wrong...

Thank you for your help. dmesg did tell me "kvm: disabled by BIOS", and I have now resolved this issue.
