Re: [Xen-devel] [PATCH] [1/4] put xen console message into syslog but x
Hi Keir
Thanks for your comments.
My modification is a simple reading interface that is independent
from the interface of "xc_readconsolering (clear/non-clear)"
that xm dmesg uses. It can be used if "clear" argument is
a negative value.
However, I also think that the "clear" interface is unnecessary.
I think that better solution is one of the following idea:
- modification to have independent read pointer of the buffer
for each commands and daemons just like reading usual file.
But, this might be difficult for hypervisor.
- modification to give the responsibility of logging of the message
to only one daemon. Other commands and daemons must read
the logging file never to issue xc_readconsolering().
best regards,
Katsuhito Minai
