Hi, I don't have clue what glibc is contained in debian, but it seems to me that at least compile-time KSM support DOES depend on glibc. I'm using RHEL5-based system and KSM support doesn't get compiled in by default. But since I use new kernel, I add following to CFLAGS while compiling qemu-kvm and then it works: -DMADV_MERGEABLE=12 -DMADV_UNMERGEABLE=13 just my 5cents regards nik On Mon, Aug 09, 2010 at 02:27:12PM +0400, Michael Tokarev wrote: > 09.08.2010 14:16, Daniel Bareiro wrote: > >Hi all! > > > >I have understood that in addition to support from the kernel and > >qemu-kvm, there must be support in libc.
