Description Raymond Mancy 2013-01-16 05:10:50 UTC
Description of problem:

When host is non responsive there is no way to re-install it, or remove it

Version-Release number of selected component (if applicable):


How reproducible:

Always

Steps to Reproduce:
1. Use RHEL6.3 host as hypervisor
2. Run a VM on it
3. Blow the hypervisor away while VM is still running on it
4. Try to remove/re-install hypervisor
  
Actual results:

"Error: Cannot switch the following Hosts to Maintenance mode: n36l-1. Hosts are non responsive and still have running VMs." (I was also unable to remove the unresponsive VM)

Expected results:

A working re-install or remove link

Additional info:

I'm not really sure how to handle this. I deleted the data centre, and that removed the VM from the "Virtual Machines" tab, however in the 'Load' column of the 'Hosts' tab it still says '1 VM' and I am still unable to re-install or put into maintainance mode. It issues the same message as above. 

I tried just adding another host with the same details, but I cannot as I would need to change the details of the broken one I can't remove, but it gives me the error:

  Error: Host Address can not be modified due to Security restrictions. In order to change Host Address, Host has to be reinstalled

I'm really not sure what to do other than re-install RHEV-M :-S

you have several options to chose from in that case:

1) add another hypervisor, and hit confirm host has been rebooted
2) force remove data-center

not sure its a bug since its a precaution measures we are taking in order to prevent data-corruption.

I already tried this (as per my above comment 'I tried adding another host'). Unfortunately I only have one machine to use as a hypervisor, so cannot add a _different_ hypervisor.

I mentioned in the original bug report "I deleted the data centre", and this also didn't help it seems.

I would be content if either of the two above options would work for me.
