Hi,
I tried googling this one - but documentation on @releaseDomain key in
xenstore seems scanty.
1. If a client registers a watch for this key - does it get called
every time a domain restarts / crashes ?
2. Why can't xenstore-ls, xenstore-read et al "see" this key ?
3. docs/misc/xenstore.txt has this to say - "WATCH
<wpath>|<token>|?
Adds a watch.
<snip>
<wpath> can be a <path> to watch or @<wspecial>. In the
latter case <wspecial> may have any syntax but it matches
(according to the rules above) only the following special
events which are invented by xenstored:
@introduceDomain occurs on INTRODUCE
@releaseDomain occurs on any domain crash or
shutdown, and also on RELEASE
and domain destruction
When a watch is first set up it is triggered once straight
away, with <path> equal to <wpath>. Watches may be triggered
spuriously. The tx_id in a WATCH request is ignored."
So would the following python code register watch for restart
events of ANY domain - 'watch = xswatch("@releaseDomain",
watch_func, xshandle())' ?
- Regards,
Ashwin
