Add a configuration item for the maximum number of domains xenstored
should support and set the limit of open file descriptors accordingly.
For HVM domains there are up to 5 socket connections per domain (2 by
the xl daemon process, and 3 by qemu). So set the ulimit for xenstored
to 5 * XENSTORED_
Xenstored is absolutely mandatory for a Xen host and it can't be
restarted, so being killed by OOM-killer in case of memory shortage is
to be avoided.
Set /proc/$pid/oom_score_adj (if available) to -500 in order to allow
xenstored to use large amounts of memory without being killed.
Make sure the
Set some limits for xenstored in order to avoid it being killed by
OOM killer, or to run out of file descriptors.
Changes in V2:
- split into 2 patches
- set limits from start script
