[Haizea] How to clear or reset the queue of haizea

[prashanth.srinivas at wipro.com]

Hi Borja,
 
Thanks for that, I have used haizea-cancel-lease command, but it is throwing "list index out of range" error and not cancelling the lease. However once I delete ~/.haizea/leases.dat file, it is working fine
 
Steps followed:
(1). First executed haizea-list-leases command
(2). Then fired haizea-cancel-lease command

Hi,

If you're just testing, you can stop Haizea, delete the persistence file
(in ~/.haizea/leases.dat) and that will make Haizea start from a clean
slate. You can also remove each lease individually using the
haizea-cancel-lease command.

However, take into account that Haizea currently does not react to
unexpected changes in OpenNebula. If Haizea starts up VMs, and you
cancel them in OpenNebula, this will put Haizea in an inconsistent
state. This will eventually be changed but, for now, it is best to not
make changes through OpenNebula (other than submitting the VMs), and
only allow Haizea to manage them.

Cheers!
