hi all,

i am trying to install kvm from source on ubuntu 12.04. i have already managed it using apt-get and can confirm it works, but since i want to try to modify it i need to do it from source.

i followed the guide here, after downloading and extracting this. then i moved into that folder and did the following:

./configure --prefix=/usr/local/kvm

make

sudo make install

sudo /sbin/modprobe kvm-intel

this passed without any problem.
then i create a vm as suggested on the guide using :

/usr/local/kvm/bin/qemu-img create -f qcow2 vdisk.img 10G

sudo /usr/local/kvm/bin/qemu-system-x86_64 -hda vdisk.img -cdrom /home/mus/downloads/ubuntu.iso \ -boot d

however the command

virsh -c qemu:///system list

whilst confirming that kvm is running, does not show that a kvm virtual machine is running, so i suspect what starts up is only running in qemu (rather than kvm). i have followed the instructions on the official guide to the letter. can anybody suggest what i might be doing wrong please?

you started the VM with qemu-kvm directly, and want to see the VM run using virsh? will never work, because virsh is part of libvirt, and in order for it to manage VMs, VMs need to be started through it.

define the VM in libvirt, and then start it using `virsh start` - then virsh list will show it

thanks for that, i was confused because it seemed to be working like a proper vm. this means that kvm is running nicely and now i can hopefully have a go at messing around with it.
