GitHub user Milena-devops added a comment to the discussion: Unable to start VM on the host
The log points less to a VM startup problem and more to a host-specific storage or libvirt issue. The Failed to lock byte 100 error usually indicates that the disk image or ISO is locked, the shared storage isn't mounted consistently, or there's a mismatch in the host's libvirt/qemu configuration. If the other hosts are working normally, compare the affected host's libvirt, qemu, storage mounts, and permissions against a healthy host. We've seen similar host-specific issues while managing IaaS environments at AccuWeb.Cloud, and in most cases the root cause turned out to be storage locking or configuration drift on a single KVM host rather than the cloud management layer itself. Comparing a working host with the affected one is usually the fastest way to isolate the difference.
