  1. VC Deployment Script for OpenNebula/KVM Yoshio Tanaka, Akihiko Ota (AIST)

  2. Demo Environments & Prerequisites • Demo Environment • OpenNebula Version 3.6 (built from source bundles) • 1 front node + 4 compute nodes • Each node has 500GB SSD • Prerequisites • The user is able to register/delete VM images to/from OpenNebula • The following network resources are available in OpenNebula • pragmapub (public network addresses) • pragmapriv (private network addresses) • vc-in.xml and image files are available in the same directory (e.g. /gfarm/vm-images/SDSC)

  3. Step 1/4 • Embed CONTEXT script$ sudo ./pragma-makeover.pl /gfarm/vm-images/SDSC/calit2-119-222.xmlCONTEXT script will set the following parameters and output vc-out.xml • IP addresses / netmasks • default gateway • /etc/resolve.conf • /etc/hosts • hostname • sshd

  4. Step 2/4 • Register the image to OpenNebula$ ./pragma-register.pl /gfarm/vm-images/SDSC/calit2-119-222.xmlThis may take 3 minutes (on SSD) or 12-15 minutes (on HDD).Check the status by oneimage command$ oneimage top

  5. Step 3/4 • Boot a VC$ ./pragma-boot.pl –c 3 /gfarm/vm-images/SDSC/calit2-119-222.xmlFirst, boot a front node, then boot compute nodes.Booting the front node may take 3 minutes (on SSD) or 12-15 minutes (on HDD).Check the status by onevm command

  6. Step 4/4 • Login and test the VC$ sshroot@163.220.57.203$ ssh hosted-vm-0-0-1 • We haven’t provided scripts for shutdown the VC and delete VM images. Need to use OpenNebula commands.ex:$ onevm shutdown 157 # shutdown compute node$ onevm shutdown 154 # shutdown front node$ oneimage delete 20 # delete VM image for compute node$ oneimage delete 21 # delete VM image for front node

  7. Comments • Do we need vcdb.txt? • AIST provides vc-in.xml as a command-line argument. Is it enough isn’t it? • Do we need mac/ip addresses in vc-in.xml? • Are there needs to use the mac/ip addresses in vc-in.xml? • These are site-specific and actually AIST does not using them.
