Hi All,
I am interested in Linux kernel development. I have subscribed for newbies mail for a while and this is my first mail to the group. My intention and interest is to work on network( if possible mm) side of kernel. First of all thanks for all the kernel developers and the guys here for contribution to Linux community.
Here is my doubt.
1) I downloaded the linux source code and created the config using make defconfig and created image using make ( I did not do make install as I want test it with kvm)
I have windows 7 system and I have installed ubuntu using vmware. I have installed KVM on ubuntu and I am trying to boot the kernal image with KVM. But I am not sure what is the problem. I am stuck in this screen. Is something I am missing here?
The approach using kvm to put some logs and to see module initialization is wrong?.
The command I am using
kvm -kernel ./arch/x86/boot/bzImage -append root=/root/
I see the below message and then the qemu prompt does not boot and stops by displaying below traceback.
Could not access KVM kernel module: No such file or directory
failed to initialize KVM: No such file or directoryQEMU
