One of my latest patches (d8db0f9690) created support for setting the limit for the maximum of opened files by qemu user. However, since libvirtd keeps one FD opened per domain (well, for qemu at least) it will likely hit this limit on huge scenarios. --- daemon/libvirtd.aug | 1 + daemon/libvirtd.c | 37 +++++++++++++++++++++++++++++++++++++ daemon/libvirtd.conf | 9 +++++++++ 3 files changed, 47 insertions(+), 0 deletions(-)
IMHO, this is the kind of thing that should be done by the system init scripts.

In that case, can you give me a hint how to change that limit on RHEL-6? Esp. when I am not running libvirtd service by hand but via Upstart init? Because all my attempts to change /etc/security/limits.conf were not successful.
For SysV init, the /etc/init.d/libvirtd and /etc/sysconfig/libvirt scripts will need to explicitly call ulimit to set this. For SystemD, you can just add LimitNOFILE=NNNN to the libvirtd.service definition Daniel -- |: http://berrange.com -o- http://www.flickr.com/photos/dberrange/ :| |: http://libvirt.org -o- http://virt-manager.org :| |: http://autobuild.org -o- http://search.cpan.org/~danberr/ :| |: http://entangle-photo.org -o- http://live.gnome.org/gtk-vnc :|
