rohityadavcloud opened a new issue, #7942:
URL: https://github.com/apache/cloudstack/issues/7942
On a 4.18.1.0 RC2 adv zone KVM env using local only storage and local
storage for systemvms, migration fails from kvm1 to kvm2 due to the following
seen in the target kvm host
```

```
The above can sometimes cause the VM to crash as it fails right at the last
step on the dest. kvm host end, and CloudStack may further report that domain
is not running.
However, systemvm migration with storage work. I'm not sure if this is an
env issue or a bug.
