Hello all, I find this curious behavior that libvirt will automatically insert a USB controller and a memballoon virtio driver into the domain's XML, when defineXML is called. IOW, the original XML did not have these 2 devices but they are present right after defineXML is called. Why should libvirt add a USB controller? DETAILS: Here is a little Python snippet to show that behavior:

Hi I have just started to investigate the possibilities of resizing memory for my kvm virtual machines on the fly. It works just fine with virsh setmem and that's great. Now, what I'm wondering about is the <memory> directive in the xml domain definition. Why would I not just set that to the size of available RAM in the host machine? Am I missing some nuance or finesse to the

Hi all. I was using libvirt under Debian squeeze (I guess it was 0.8.3-5+squeeze4 or something similar). I was able to clone machines with below command: sudo virt-clone --connect=qemu:///system -o template -n template_clone -f /var/lib/libvirt/images/template_clone.qcow2 After that I was able to start the VM and connect to the console: sudo virsh console template_clone I recently Installed

Hello, I've been trying to boot a VM with the rootfs being a 9P share from the host. The VM OS is centos 7. The OS boots but no services can work and it appears that the authentication system is broken. Now the funny thing is that booting the same OS on the same 9P share manually with Qemu works as expected with a fully functionnal OS... So I'm wondering what could libvirt do that render
