New issue 665 by [email protected]: RpcCallJobqueueUpdate does not
virtualize the file path
http://code.google.com/p/ganeti/issues/detail?id=665
What steps will reproduce the problem?
1. Set up a vcluster with a couple of nodes.
2. Run ./cmd 'gnt-cluster verify'
3. Get lots of error messages about ssh problems:

Digging through the code I found out that the problem is in Rpc.hs
RpcCallJobqueueUpdate. The path in the variable 'file_name' of the RPC call
needs to be virtualized, but this is missing here.
For comparison, the virtualization in the python code is done in jqueue.py,
CallJqUpdate:
virt_file_name = vcluster.MakeVirtualPath(file_name)
So basically, the functionality of "MakeVirtualPath" needs to be
implemented in Haskell.
Please use labels and text to provide additional information.
To verify, that it is indeed this call, I logged the jobqueue_update RPC
calls in the backend and marked the haskell ones with "ZZZ". Excerpt from
