Hi, all!
I installed qemu-kvm-0.12.1.1 in one equipment of my house yesterday to
test it with Linux 2.6.32 compiled by myself from the source code of
kernel.org.
From the night of yesterday that I am observing a high use of swap. This
is the Service Log Entries from Nagios:
12-26-2009 21:57:33 12-26-2009 23:42:33 0d 1h 45m 0s SERVICE WARNING (HARD) SWAP WARNING - 30% free (142 MB out of 486 MB)
12-26-2009 23:42:33 12-27-2009 00:00:00 0d 0h 17m 27s SERVICE CRITICAL (HARD) SWAP CRITICAL - 9% free (41 MB out of 486 MB)
12-27-2009 00:00:00 12-27-2009 06:27:33 0d 6h 27m 33s SERVICE CRITICAL (HARD) SWAP CRITICAL - 5% free (22 MB out of 486 MB)
12-27-2009 06:27:33 12-27-2009 12:49:51 0d 6h 22m 18s+ SERVICE WARNING (HARD) SWAP WARNING - 14% free (67 MB out of 486 MB)
The hour has been ART (GMT-3).
The VMs running in this host are the following:
+--------------------+----------+------------------+
| OS | RAM | SWAP |
+====================+==========+==================+
| Debian Lenny amd64 | 512 MB | 1 GB / 0 used |
| Debian Lenny amd64 | 512 MB | 512 MB / 0 used |
| Debian Lenny amd64 | 512 MB | 1 GB / 584k used |
| Debian Lenny i386 | 512 MB | 512 MB / 0 used |
| OpenBSD 4.6 i386 | 512 MB | 1 GB / 0 used |
+--------------------+----------+------------------+
This is what I obtain with 'free' in the host:
root@ubuntu:~# free
total used free shared buffers cached
Mem: 4060340 3989512 70828 0 1804272 95212
-/+ buffers/cache: 2090028 1970312
Swap: 497972 415680 82292
To what that so high use of swap can be due?
Thank in advance for your replies.
Regards,
Daniel
