verendrakalsi opened a new issue, #10585: URL: https://github.com/apache/cloudstack/issues/10585
followed all the required steps mentioned in this document regarding the prerequisites for migrating VMs from "Import-Export Insatnce"section in cloudstackUI.  Also since it was windows VM we had also install following tools on the KVM host. wget https://fedorapeople.org/groups/virt/virtio-win/direct-downloads/stable-virtio/virtio-win.noarch.rpm # install “alien” which can convert rpms to debs apt -y install alien # the conversion, can take a while alien -d virtio-win.noarch.rpm # install the resulting deb dpkg -i virtio-win*.deb In addition to this, we need to install the below package as well to avoid the error “[virt-v2v: error: One of rhsrvany.exe or pvvxsvc.exe is missing in /usr/share/virt-tools](https://github.com/rwmjones/rhsrvany#note-for-virt-v2v-users)“. wget -nd -O srvany.rpm https://kojipkgs.fedoraproject.org//packages/mingw-srvany/1.1/4.fc38/noarch/mingw32-srvany-1.1-4.fc38.noarch.rpm alien -d srvany.rpm dpkg -i *srvany*.deb When installing virt-v2v on Ubuntu KVM hosts, the “nbdkit” package (which is required to convert VMware Instances) is not installed by default. To install it, execute the following command: apt install virt-v2v apt install nbdkit The OVF tool (ovftool) must be installed on the KVM hosts if the hosts should export VM files (OVF) from vCenter. If not, the management server exports them using internal java lib code. Download the ovftool from https://developer.broadcom.com/tools/open-virtualization-format-ovf-tool/latest unzip VMware-ovftool-4.6.3-24031167-lin.x86_64.zip -d /usr/local/ #create a soft link ln -s /usr/local/ovftool/ovftool /usr/local/bin/ovftool Error However we keep getting this error now.
