Bug Description
The commit c1ccc1a3165ec15
a regression when NUMA live migration was done on shared storage
# No instance booting at source host, but instance dir
# must be deleted for preparing next block migration
# must be deleted for preparing next live migration w/o shared
# storage
# vpmem must be cleaned
Based on the commit, if any type of NUMA system is used with shared storage. Live migration will delete the backing folder for the VM, making the VM unusable for future operations.
