That is very strange. I can't see any reason why you (or anyone) should
be disallowed from following up to that mail. (I'm CCing the bug again
and not trimming the quotes for that reason).
I think the issue that you (and the original submitter) are having is
the same as #603632. I applied a fix to the kernel for that issue
yesterday. For this reason I'm merging this but with that one with this
email.
WRT "Memory used once by a domU won't bee freed after shutdown or
destroy of those domUs" -- if domain 0 is ballooned down in order to
start a guest then domain 0 is not automatically ballooned back up when
the domain in shut down. The memory is freed to the hypervisor just not
reallocated to domain 0 and you should see it in the "xm physinfo"
output.
You should be able to manually balloon domain 0 back up again or else
the memory will be used for the next guest you start.
This is the defined behaviour of xend (I hesitate to say "expected
behaviour" since it's not all that obvious).
