Re: [Xen-devel] [Patch] for expanding the vbd devices

[Hidetoshi Nishi <nishi.hidetoshi@xxxxxxxxxxxxxx>]

　Hi Keir-san,
　
　I'm very sorry to be late for the response.
　
　I think we have still porblem for user wish to use many disks.
　As you say, "there are quite a few steps involved but that is
  very slow", I think so too. But Time-Out occurs to create Domain
  is more important problem.
  
  I think we have two way to fix time-out problem quickly.
  - extend the timer value
  - be able to set timer value with config file according to number of 
    disks
    
  Please let me know about these.
  
  Thank you                                      Nishi
