OneSwap

oneswap aims to provide a smooth VM migration path from vCenter to OpenNebula KVM

Prerequisites:

• virt-v2v
• libguestfs-tools
• nbdkit
• nbdkit-plugin-dev
• nbdkit-plugin-libvirt
• libguestfs-xfs ( for XFS guests )
• libguestfs-zfs ( for ZFS guests )

Optional requirements:

• vddk library
  • VDDK library is not freely distributable and you can download it from VMWare's Developers Portal
• RHSrvAny.exe - for Windows Context Injection
  • https://github.com/rwmjones/rhsrvany

Required Tools for converting Windows Guests:

• Download and install rhsrvany tools from GitHub:
  • https://github.com/rwmjones/rhsrvany
  • Download latest version of the RPM found at https://rpmfind.net/linux/rpm2html/search.php?query=mingw32-srvany
  • Extract EXE's from rpm package by executing:
    • rpm2cpio srvany.rpm | cpio -idmv \ && mkdir /usr/share/virt-tools \ && mv ./usr/i686-w64-mingw32/sys-root/mingw/bin/*exe /usr/share/virt-tools/
• Download VirtIO ISO drivers for Windows to the /usr/share/virtio-win/ directory:
  • https://fedorapeople.org/groups/virt/virtio-win/direct-downloads/stable-virtio/virtio-win.iso
• Maybe the QEMU guest agent as well, since virt-v2v

If you are going to install context on the guest with this utility:

• Download necessary context packages from the github
• Place them all in a specific directory, default at /var/lib/one/context/ ( --context argument )
