Hi,

firstly, feel free to write to the list, not just particular people.
There are many more people on the list that may help you.  Not
mentioning that those people you write might not be available, don't
have time etc.

There was a similar question to the one you've asked, you could have
checked that out before as well and reply on it.  There's also a patch
fixing cpu-stats command, check it that helps.

This basically means that you have old qemu that doesn't support (I'm
guesing the command now) "query-vcpus" QMP command.  The problem
probably lies somewhere else, even though my change might have caused
the other part to behave differently.

According to the logs, it looks like it's completely the same like a
question already asked...  Wanting to post the link here, I've found
that even the machine name is the same, so it shouldn't be a problem for
you to find it.

I'm looking  at the issue now, so I'll see what I can do, but maybe in
the meantime sombody else will reply.
