Bug#871702: Latest Stretch qemu-system-i386 process balloons in Xen Dom0 RAM, crashes DomU

[Darius Spitznagel]

Hello,

I can confirm this bug.
Xen dom0 balloons endlessly and consumes all swap.
Then dom0 kills one domU after another.
Downgrading to qemu-system-x86 1:2.8+dfsg-6 helps solving the problem 
for me too.
Same system with KVM is not affected.
