Is this server missing the KVM kernel module? (I ask because KVM isn’t working properly, VMs are starting and freezing at BIOS)
root@box:~# lsmod | grep kvm root@box:~# root@box:~# /etc/init.d/qemu-kvm start Loading kvm module kvm_intel. root@box:~# lsmod | grep kvm root@box:~# root@box:~# modprobe kvm_intel root@box:~# lsmod | grep kvm root@box:~#
On another box I have running KVM;
root@box2:~# lsmod | grep kvm kvm_intel 115159 0 kvm 291655 1 kvm_intel root@box2:~#
Am I missing the KVM kernel module, or is this not how it should be loaded? If I am missing it, I assume I need to recompile the Kernel to get it back, is that correct?
root@box:~# cat /etc/issue Debian GNU/Linux 6.0 \n \l root@box:~# uname -a Linux box1 3.4.9 #1 SMP Mon Sep 3 17:09:07 BST 2012 x86_64 GNU/Linux
Answer
After much log searching and sifting, I found one entry (in dmesg
after a reboot) that said something like “Loading KVM Kernel module… Stopped (or disallowed) by BIOS”.
Virtual extensions where turned off in the BIOS, I never do that so I never checked it.
