Category: None Group: None Status: Open Resolution: None Priority: 5 Private: No Submitted By: tgr (tgr1) Assigned to: Nobody/Anonymous (nobody) Summary: huge memory leak (qemu-kvm 0.12.3) Initial Comment: CPU: Xeon E5450 KVM: qemu-kvm 0.12.3 Host: Debian Squeeze amd64, kernel 2.6.32 Guest: Debian Lenny amd64, kernel 2.6.26 qemu command line below (no helpers like libvirt used) whether the problem goes away if using the -no-kvm-irqchip or -no-kvm-pit switch: seems unrelated whether the problem also appears with the -no-kvm switch: load profile of the guest makes running without KVM infeasible The problem: after 4 days, the kvm process of a guest run with -mem 3072 takes 12 GB VSZ / 9 GB RSS - grows until OOM ("kvm invoked oom-killer" in dmesg). At that point the guest shows more than 2 GB of free memory. qemu command line: kvm -smp 4 -m 3072 -net nic,vlan=0,model=virtio,name=eth0,macaddr=x:x:x:x:x:x -net tap,vlan=0,ifname=tap6 -net nic,vlan=1,model=virtio,name=eth1,macaddr=x:x:x:x:x:x -net tap,vlan=1,ifname=tap7 -drive if=virtio,file=/dev/x/x-rootfs,index=0 -drive if=virtio,file=/dev/x/x-swap,index=1 -name x -nographic -kernel /boot/vmlinuz-2.6.26-2-amd64 -initrd /boot/initrd.img-2.6.26-2-amd64 -append root=/dev/vda console=ttyS0 -echr 2 -serial mon:telnet:localhost:12344,server,nowait -monitor unix:/var/run/kvm-x,server,nowait -daemonize -watchdog i6300esb -watchdog-action reset (the monitor on both telnet and unix socket is intentional, the one on the socket is only used for sending system_reset and system_powerdown qemu commands). ---------------------------------------------------------------------- You can respond by visiting: https://sourceforge.net/tracker/?func=detail&atid=893831&aid=2989366&group_id=180599 -- To unsubscribe from this list: send the line "unsubscribe kvm" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
