KVM

I've recently been looking at libvirt which has a GUI called Virt Manager. I t seems quite flexible including being able to use logical volumes as raw disks for a VM. Uses Qemu/KVM as the virtualisation engine. It's all in the Ubuntu repositories too.

Worth a look?

Regards,
Tony.

I normally create an VM with enough storage for the OS running in the VM, and then add additional storage for it to use. The added storage can be a whole hard drive, or just a 'virtual disk' which is a file on a drive somewhere.


OK, so this is what I was thinking of doing.

There's lots of ways to do it, and the best way to do it should be determined by you through trial and error.


OK, I guess my question is what ones should I try.  I have started reading http://www.linux-kvm.org/page/9p_virtio which seems a good one to try.  It mentions QEMU which I have come across, but cant quite work out what it is.

I like using virtual disk files because they're a little bit easier to copy to other places to back them up.


Exactly why I want to to do  it.

Hi.  I am starting to look at KVM.  I want to set up a VM for a ownCloud server.  I get that I create a disk image for the VM but cant work out if I am supposed to put all the (owncloude) date in the VM image or create a separate (i.e. /owncloud) filesystem on the host machine and share it with the VM.

I would rather not put the owncloud data in the VM as if I do I dont think I can just backup the VM without backing up the data also.

On a side not I haven't used Ubuntu for a while and went to the forum to ask this question but was unable to post, what gives?

Ben
