4.3.5. Scripted bulk v2v process

Procedure 4.9. Configuring and running the scripted bulk v2v process

1. Ensure the REST API is enabled on the Red Hat Enterprise Virtualization Manager, and it is accessible from the Linux host running the v2v process. For more information about the REST API, see the Red Hat Enterprise Virtualization REST API Guide Guide.
2. On the Linux host, create the file v2v.sh with the following contents. Ensure you edit the script to contain appropriate values for your environment.

   Example 4.5. Single host v2v script

   #!/bin/sh
   # Declare all VMs to import
   XENDOMAINS=("rhelxen" "rhel5")
   KVMDOMAINS=("rhelkvm")
   VMWAREVMS=("rhel54vmware")
   
   # Iterate through each Xen domain, performing the conversion
   for domain in ${XENDOMAINS[@]}
   do
           virt-v2v -ic xen:///localhost -o rhev -os storage.example.com:/exportdomain --network rhevm $domain
   done
   
   # Iterate through each KVM domain, performing the conversion
   for domain in ${KVMDOMAINS[@]}
   do
           virt-v2v -o rhev -os storage.example.com:/exportdomain --network rhevm $domain
   done
   
   # Iterate through each VMware VM, performing the conversion
   for vm in ${VMWAREVMS[@]}
   do
           virt-v2v -ic esx://esx.example.com/?no_verify=1 -o rhev -os storage.example.com:/exportdomain --network rhevm $vm
   done
   
   
   # Call the import VM procedure remotely on the RHEV Manager
   
   export BASE_URL='https://[rhevm-host]'
   export HTTP_USER='user@internal'
   export HTTP_PASSWORD='password'
   
   curl -o rhevm.cer http://[rhevm-host]/ca.crt
   
   # Get the export storage domains
   
   curl -X GET -H "Accept: application/xml" -u "${HTTP_USER}:${HTTP_PASSWORD}" --cacert rhevm.cer ${BASE_URL}/api/storagedomains?search=nfs_export -o exportdomain
   EXPORT_DOMAIN=`xpath exportdomain '/storage_domains/storage_domain/@id' | sed -e 's/ id=//' | sed -e 's/"//g'`
   
   # Get the datacenter
   
   curl -X GET -H "Accept: application/xml" -u "${HTTP_USER}:${HTTP_PASSWORD}" --cacert rhevm.cer ${BASE_URL}/api/datacenters?search=NFS -o dc
   DC=`xpath dc '/data_centers/data_center/@id' | sed -e 's/ id=//' | sed -e 's/"//g'`
   
   # Get the cluster
   
   curl -X GET -H "Accept: application/xml" -u "${HTTP_USER}:${HTTP_PASSWORD}" --cacert rhevm.cer ${BASE_URL}/api/clusters?search=NFS -o cluster
   CLUSTER_ELEMENT=`xpath cluster '/clusters/cluster/@id' | sed -e 's/ id=//' | sed -e 's/"//g'`
   
   # List contents of export storage domain
   
   curl -X GET -H "Accept: application/xml" -u "${HTTP_USER}:${HTTP_PASSWORD}" --cacert rhevm.cer ${BASE_URL}/api/storagedomains/${EXPORT_DOMAIN}/vms -o vms
   
   # For each vm, export
   VMS=`xpath vms '/vms/vm/actions/link[@rel="import"]/@href' | sed -e 's/ href="//g' | sed -e 's/"/ /g'`
   
   for vms in $VMS
   do
           curl -v -u "${HTTP_USER}:${HTTP_PASSWORD}" -H "Content-type: application/xml" -d '<action><cluster><name>cluster_name</name></cluster><storage_domain><name>data_domain</name></storage_domain><overwrite>true</overwrite><discard_snapshots>true</discard_snapshots></action>' --cacert rhevm.cer ${BASE_URL}$vms
   done
   
   

   Note

   Use the POST method to export virtual machines with the REST API. For more information about using the REST API, see the Red Hat Enterprise Virtualization REST API Guide.
3. Run the v2v.sh script. It can take several hours to convert and import a large number of virtual machines.
