"virt-v2v is a tool for converting and importing virtual machines to
libvirt-managed KVM (Kernel-based Virtual Machine).

Using virt-v2v to convert a guest that has a password-protected VNC
console to a KVM guest removed that password protection from the
converted guest: after conversion, a password was not required to
access the converted guest's VNC console. Now, converted guests will
require the same VNC console password as the original guest. Note that
when converting a guest to run on RHEV, virt-v2v will display a
warning that VNC passwords are not supported. (CVE-2011-1773)

Bug fixes :

  - When converting a guest virtual machine (VM), whose name
    contained certain characters, virt-v2v would create a
    converted guest with a corrupted name. Now, virt-v2v
    will not corrupt guest names.

  - There were numerous usability issues when running
    virt-v2v as a non-root user. This update makes it
    simpler to run virt-v2v as a non-root user.

  - virt-v2v failed to convert a Microsoft Windows guest
    with Windows Recovery Console installed in a separate
    partition. Now, virt-v2v will successfully convert a
    guest with Windows Recovery Console installed in a
    separate partition by ignoring that partition.

  - virt-v2v failed to convert a Linux guest which did not
    have the symlink '/boot/grub/menu.lst'. With this
    update, virt-v2v can select a grub configuration file
    from several places.

  - This update removes information about the usage of
    deprecated command line options in the virt-v2v man
    page.

  - virt-v2v would fail to correctly change the allocation
    policy, (sparse or preallocated) when converting a guest
    with QCOW2 image format. The error message 'Cannot
    import VM, The selected disk configuration is not
    supported' was displayed. With this update, allocation
    policy changes to a guest with QCOW2 storage will work
    correctly.

  - The options '--network' and '--bridge' can not be used
    in conjunction when converting a guest, but no error
    message was displayed. With this update, virt-v2v will
    now display an error message if the mutually exclusive
    '--network' and '--bridge' command line options are both
    specified.

  - virt-v2v failed to convert a multi-boot guest, and did
    not clean up temporary storage and mount points after
    failure. With this update, virt-v2v will prompt for
    which operating system to convert from a multi-boot
    guest, and will correctly clean up if the process fails.

  - virt-v2v failed to correctly configure modprobe aliases
    when converting a VMware ESX guest with VMware Tools
    installed. With this update, modprobe aliases will be
    correctly configured.

  - When converting a guest with preallocated raw storage
    using the libvirtxml input method, virt-v2v failed with
    the erroneous error message 'size(X) < usage(Y)'. This
    update removes this erroneous error.

  - When converting a Linux guest, virt-v2v did not check
    that the Cirrus X driver was available before
    configuring it. With this update, virt-v2v will attempt
    to install the Cirrus X driver if it is required.

  - VirtIO systems do not support the Windows Recovery
    Console on 32-bit Windows XP. The virt-v2v man page has
    been updated to note this. On Windows XP Professional
    x64 Edition, however, if Windows Recovery Console is
    re-installed after conversion, it will work as expected.

  - Placing comments in the guest fstab file by means of the
    leading '#' symbol caused an 'unknown filesystem' error
    after conversion of a guest. With this update comments
    can now be used and error messages will not be
    displayed.

Users of virt-v2v should upgrade to this updated package, which fixes
these issues and upgrades virt-v2v to version 0.8.3."
