Reportedly, after this patch, HVM DomUs running with qemu-system-i386 (note i386, not x86_64), are leaking memory and host is running out of memory rather fast. See for example https://bugs.debian.org/871702 I've asked for details, let's see... For one, I've no idea how xen hvm works, and whenever -i386 version can be choosen in config or how. Thanks, /mjt
