Re: [libvirt] [PATCH] Increase default file handle limits for daemons

Linux still defaults to a 1024 open file handle limit. This causes scalability problems for libvirtd / virtlockd / virtlogd on large hosts which might want > 1024 guest to be running. In fact if each guest needs > 1 FD, we can't even get to 500 guests. This is not good enough when we see machines with 100's of physical cores and TBs of RAM. In comparison to other memory requirements of libvirtd & related daemons, the resource usage associated with open file handles is essentially line noise. It is thus reasonable to increase the limits unconditionally for all installs.
