    vSphere Domain Name, VMware Datacenter Name are values that have to be leveraged on VMware.

    The URL above have to be built by pointing to your own VMware environment.

    Hi ,

    Is it possible to migrate Microsoft Windows Virtual machine from VMware vSphere to Oracle Linux KVM host.

    virt-v2v in Oracle linux KVM is unable to read NTFS partition ."No root device found in this operating system image"

    Hi,

    It appears that inspection failed because libguestfs couldn't read the NTFS filesystem.

    Can you check if you have "libguestfs-winsupport" package installed on the KVM Host where you are trying to import the Windows VM via virt-v2v?

    If not, please install it using command and retry Windows VM import:

    # yum install libguestfs-winsupport

    Make sure you have following repositories: ol7_latest and (ovirt-4.2 , ovirt-4.2-extra) Or (ovirt-4.3 , ovirt-4.3-extra) enabled for installing the package with all required dependencies.

    Let us know the outcome.

    Regards,

    Hi there,

    Excellent article! Thank you Simon.

    When I follow your procedure I bump into the following error:

    qemu-img Unknown driver 'https'

    Can't really figure out what's going wrong. I'm new to Oracle Linux KVM. Any help would be greatly appreciated!

    Kind regards

    Kristof

    Do you intend to document using virt-p2v to boot and convert a physical server?

    I attempted to follow the docs and hit two dead ends:

    https://libguestfs.org/virt-p2v.1.html

    https://libguestfs.org/virt-p2v-make-kickstart.1.html

    I couldn't find any Oracle Linux package for livecd-creator.

    https://libguestfs.org/virt-p2v-make-disk.1.html

    [[email protected] v2v]# virt-p2v-make-disk --inject-ssh-identity id_rsa -o p2v.img

    virt-p2v-make-disk: internal error: could not work out the Linux distro from 'ol-7.8'

    Due to dependencie errors, installation of qemu-block-curl is not possible with the limitation of the developer_kvm_utils package as described in the very first link:

    To successful install you will need these packets, too:

     qemu-common         x86_64     15:4.2.1-3.el7        ol7_developer_kvm_utils     1.7 M

     qemu-kvm           x86_64     15:4.2.1-3.el7        ol7_developer_kvm_utils     9.4 k

     qemu-system-x86       x86_64     15:4.2.1-3.el7        ol7_developer_kvm_utils     9.8 k

     qemu-system-x86-core     x86_64     15:4.2.1-3.el7        ol7_developer_kvm_utils


    What do you think about the support situation? Can we install these packets safely? Because if not, the mmigration seems to be unusable...

    QEMU packages are leveraged by Production "kvm_utils" Yum channel that, by default, is enabled on Oracle Linux KVM hosts.

    yes, that is true, but not not in the right version, as you can see in above examples.
