Hi,
I have a problematic CentOS XEN server and hope someone could point me in the right direction to optimize it a bit.
The server runs on a Core2Quad 9300, with 8GB RAM (max motherboard can take, 1U chassis) on an Intel motherboard with a 1TB SATA HDD.
dom0 is set to 512MB limit with a few small XEM VM’s running:
root@zaxen01:[~]$ xm list Name ID Mem(MiB) VCPUs State Time(s) Domain-0 0 512 4 r----- 96.5 actionco.vm 3 1519 1 -b---- 14.8 byracers.vm 4 511 1 -b---- 85.7 ns1 5 511 1 -b---- 22.3 picturestravel 6 255 1 -b---- 13.3 rafttheworld 7 255 1 -b---- 11.3 zafepres.vm 8 511 1 -b---- 19.0the server itself seems to eat up a lot of resources:
root@zaxen01:[~]$ free -m total used free shared buffers cached Mem: 512 472 39 0 13 215 -/+ buffers/cache: 244 268 Swap: 4095 0 4095Yet, it only has XEN, Webmin (since it’s a CloudMin XEN server), Exim, Apache and a few other services running:
root@zaxen01:[~]$ chkconfig --list |grep "3:on" |awk '{print $1}' |sort acpid auditd crond csf dhcpd exim haldaemon httpd iptables iscsi iscsid kudzu lfd lvm2-monitor mdmonitor network qemu restorecond setroubleshoot smartd snmpd sshd syslog sysstat webmin xend xendomainsIs there anything I can optimize on such a server?
