A page to gather notes on virtualization infrastructure relevant for OSG related activities (ITB, workshops, Tier 3 support, etc).
VM machine types
These are for a typical OSG cluster farm.
- Basic SL 5.3 server
- NFS server
- Head node
- Condor master
- Storage server
- BestmanGateway + Gridftp server
- Local disk partition
- Worker node
- GUMS server
default vm configuration?
vlan 101 internal network, vlan 624 external network
how to make a vm start on bootup of vmware?
how to remove a vms disk files after its no longer needed?
select vm, inventory -> virtual machine -> remove from inventory vs delete from disk
Disk files are stored like [datastore 1] itb gums/itb gums.vmdk
vmdks are vmware disks:
Virtual Machine Disk Format (VMDK) - VMware http://www.vmware.com/technical-resources/interfaces/vmdk.html
Create a new VM
name it itbv-c001
ITB vms should start with itbv-
select datastore datastore1
vm version 7
guest os linux
redhat enterprise linux 5 64bit
we will give a worker 2cpus so nonjob processes can run well while the job is running
2GB memory to run one job aka "2056MB"
network for a worker is internal,
vlan 101 network
lsi logic parallel scsi controller
important to select "Allocate and commit space on demand (thin provisioning)
"Thin Provisioning lets vSphere Administrators subscribe more capacity to virtual machines than they actually have, eliminating the waste of resources and space caused by unused over-allocated storage."
50GB disk for a single core worker
select "store with the virtual machine" for location
virtual device node scsi 0:0
then click create
now you have an entry in the vm list under itbv-esx1
you cant see the mac address yet, we have to start the vm
so select your new vm->power->power on
then click console and watch it boot, try to get the MAC
add to uct2-mgt dhcpd.conf
add to cobbler
sync up cobbler and dhcp, select power->reset on the vm
when it boots up cobbler should install!
