Issue while migrating window or ubuntu VM from VMware vcenter #10585
Description
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“.
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.
These are the agent.log outputs
