Hi Keir,
Thank you for reply.
This patch was able to change CD-ROM by closing the device.
However, another problem might break out in paraVM.
Do you think that you should correct it by what method?
Do you have a good idea?
It seems bizarre that any good could come of calling vbd_free() from
vbd_create(). One is the opposite of the other.
I do not think that this method is good either.
Then, do you think that the following method is good?
Or, is there a good method for another?
I think that it is necessary to reopen the device by telling vbd to have
changed.
Therefore, the change of CD-ROM is told from Dom0 by the xm command.
(xm block-configure etc)
Thanks
