building a large scaled monitoring system for a customer with icinga 1.4.0 + pnp4nagios 0.6 (bulk mode with npcd), db logging. it will monitor very different stuff …. from servers to network, from esx(i) to linux machines, from firewalls to printers … good to see that all the needed software comes from the debian stable repositories (non-free). once again debian FTW !

today i upgraded my workstation to debian testing aka wheezy with kernel 2.6.38-2-amd64. some problems with the mysql-server-5.1 and with vmware workstation 7.1.4 but overall ok. ( vmware patch : http://www.linuxinsight.com/vmware-workstation-7.1.3-runs-great-on-linux-kernel-2.6.37.html )

just updated some esxi hosts, merged a snapshot with a flatfile vm, switched 17 servers to different esxi hosts – vmware is a good product. now we can do even online backups with esxi 4.1 – ghettoVCB.sh http://communities.vmware.com/

one important thing left so say: never touch or move vms with snapshots ^^

vmware / centos 5 network settings

Posted: January 29th, 2011 | Author: | Filed under: centos, it, networking, virtualization | Tags: , , , | No Comments »

copied vm centos 5 machines with fixed ip settings to a different esxi server. put the machines in a vm net with an active dhcp server. the centos machines switched at boot-time to dhcp and automatically disabled the fixed ip settings. centos creates a new interface configuration file with dhcp settings. the old config file is backed. why ? the mac adress has changed ! (vmware moving). to prevent this you should probably configure the mac adresses from the old esxi system or adjust the network cfg files on centos.

new virtualization project

i`m planning a new virtualization structure for a customer. this time based on three ibm x3650 m3 machines; one machine as iSCSI target, the other two machines with vmware ESXi 4.1, for sure it will be real fun to configure one x3650 m3 as a iSCSI target – hoping debian stable will install clean without patching the kernel for raid modules or something ….  🙂
