Subject [jira] [Commented] (CLOUDSTACK-1648) Unable to add KVM host

ASF subversion and git services commented on CLOUDSTACK-1648:
-------------------------------------------------------------

Commit 8a50bac8a9958311f30de574d7d26c163f06c707 in branch refs/heads/4.0 from Chip Childers
<chip.childers@gmail.com>

CLOUDSTACK-1648 - KVM - make storage pools non-persistent in libvirt. Persisting
cloud-defined resources on the host has caused various problems. As a backward
compatible fix, if an existing pool with a different name collides with a pool
being created (by path), the pool will be redefined with the name cloudstack
knows about. This is actually what brought up the bug, a persisted storage pool
cloudstack wasn't managing.

> Trying to add a kvm host in basic zone.
> Failed after time out occured.
> Checked the agent log in KVM host, seems like conflict occurring with storage pool.
> Tried removing the storage pool and re-installing the cloudstack agent.
> Even then failing on the same error.
