[Xen-devel] qemu-system-i386: memory leak?

[Maik Wessler <maik.wessler@xxxxxxxxx>]

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} dom0_mem=1592M,max:1592M
