removing VMs logs

Hi, all. Libvirt QEMU driver writes QEMU process log to /var/log/libvirt/qemu/<VM_NAME>.log file. This file is owned by libvirt that is no API client knows about it and no client will remove it. Thus this file stays forever. I guess it does not cause harddisk space waste in some deploys as the number of VMs thru node lifecycle is not very large. In Virtuozzo we have a service which checks VMs disks every 5 min using guestfs. This generates about 100k files and about 400MiB disk usage per VM per year. This is a lot. I guess we could refine the service to avoid this issue yet I think the issue is general and need to be addressed. If this is agreed then in terms of architecture should we have a distinct timer/service to cleanup log files or we'd better clean up in scope of qemu driver itself? Nikolay
