Re: [Qemu-devel] Runtime-modified DIMMs and live migration issue

[Andrey Korolyov]

"Fixed" with cherry-pick of the
7a72f7a140bfd3a5dae73088947010bfdbcf6a40 and its predecessor
7103f60de8bed21a0ad5d15d2ad5b7a333dda201. Of course this is not a real
fix as the only race precondition is shifted/disappeared by a clear
assumption. Though there are not too many hotplug users around, I hope
this information would be useful for those who would experience the
same in a next year or so, until 3.18+ will be stable enough for
hypervisor kernel role. Any suggestions on a further debug/race
re-exposition are of course very welcomed.

CCing kvm@ as it looks as a hypervisor subsystem issue then. The
