Hi all,
I am using xen-4.2-testing.hg on debian 6.0.6 (x86_64) with Kernel 3.4.15 (tmem
enabled). Problem is that the /usr/lib/xen/bin/qemu-system-i386
use more and more memory. After one week uptime (depends on memory) the machine
starts to swap...
Details:
root@dmw01:~# cat /etc/grub.d/09_linux_xen |grep mem
multiboot${rel_xen_dirname}/${xen_basename} placeholder ${xen_args}

Given that this is a PV guest and I can see -nographic on the qemu command line I'm not what qemu is doing -- can we see the guest configuration please?

If it doesn't turn out to be this then one approach might be to arrange to run qemu under valgrind for a little bit and see if anything springs out. You'd probably need at least r13081 of Valgrind's SVN trunk to remove all the noise due to hypercalls.
