[one-users] host with both tm_ssh and tm_lvm

[Shi Jin]

Hi there,

I have another problem having two groups of drivers on the same  host.
This is the error message from the oned.log
Mon Nov  9 09:19:33 2009 [InM][I]: Monitoring host node1-ssh (9)
Mon Nov  9 09:19:33 2009 [ReM][D]: VirtualMachinePoolInfo method invoked

Mon Nov  9 09:19:34 2009 [InM][D]: Host 9 successfully monitored.
Also from vm.log:
Mon Nov  9 09:13:01 2009 [DiM][I]: New VM state is ACTIVE.
Mon Nov  9 09:13:01 2009 [LCM][I]: New VM state is PROLOG.
Mon Nov  9 09:13:01 2009 [TM][E]: prolog, error getting driver im_ssh
Mon Nov  9 09:13:01 2009 [DiM][I]: New VM state is FAILED
Mon Nov  9 09:13:01 2009 [TM][E]: epilog_delete, error getting driver
vmm_kvm. You may need to manually clean
node4-ssh:/opt/cloud/VM/175/images

I think the problem is that the im driver groups (although they are
the same) are writing on top of each other, making the script file not
available at the time of execution. I hope there can be solution to
this problem.
Thanks a lot.
