Sessions
The existing installer method copies files from a loopdev mounted rootfs to the target. This is limiting for multi-partition images (such as wic or meta-mender). Instead, we will describe how to create an installer image which uses output (image and .bmap files) from another image and writes all the partitions at once to the target using bmaptool.
Running a QEMU virtual machine with 'runqemu' or 'mender-qemu' is easy, but sometimes you want more advanced features like passing through a host USB device. While this can be done with command line tools, it gets complicated quickly. We will discuss some experiences building and launching QEMU images with tools that leverage libvirt and virtio on your host, such as virsh and virt-manager.
