dear opennebula community, i run "VBoxManage clonehd --format RAW image.vdi image.img" to convert the virtualbox .vdi vm instance to raw format, and with virt-manager to create new vm with the raw format, it works fine, i.e. can start the new vm instance successfully and the networking access is the same as before.
but after run "qemu-img convert -f raw image.img -O qcow2 image.qcow" to convert the raw format to qcow2 format, and with virt-manager to create new vm with the qcow2 format, it doesn't work, i.e. get "no bootable device" error when start the new vm with qcow2 format, no need to say the networking access. the size of the ram format disk is about 40GB, while the size of the qcow2 format disk is about 1.3GB (similar as that of the original image.vdi size), nearly 30 times smaller than the raw format. if not convert the raw format to qcow2 format, then the disk size is too large, waste of disk space. there are ubuntu 12.04, opennebula 3.6.0, and kvm, qemu, libvirt etc installed. it is much appreciated if you can help with this. thanks, david su
