• kvm

  • manual install: qemu-0.15.1, etc.

  • setup details

  • /etc/

    • qemu-ifup
    • qemu-ifdown
    • IPCONFIG
    • exports
    • exportfs -r to reread

  • empty mongo db (but keep users)

use genapptest

db.joblock.remove()
use sassie2
db.jobs.remove()
db.joblock.remove()
use sassie2test
db.jobs.remove()
db.joblock.remove()
use msgs
db.cache.remove()

below needs some future cleanup & automation

- /share/apps/genapp/__app__/output/html5
- mkdir (this may happen automatically)
  - results
  - deleted
- /share/apps/genapp/__app__
- symlinks
  - ajax
  - util
  - docs
  - results 
  - deleted
- chown -R apache:apache .
- chmod -R g+rw .

ln -s output/html5/ajax ajax
ln -s output/html5/util util
ln -s output/html5/results results
ln -s output/html5/deleted deleted
# docs for sassie
ln -s /var/www/htdocs/docs docs

isn't useful

• centos6.6 uses qemu-0.12x and is not compatible with even reasonably modern versions of qemu (e.g. qemu-0.15.1!)
• so forget this:
  • KVM install notes
  • modified by:
    • semanage fcontext -a -t virt_image_t "/home/kvm(/.*)?"; restorecon -R /home/kvm
  • virt notes

 Create a guest from an existing disk image 'mydisk.img' using defaults for the rest of the options.
         # virt-install --name demo --ram 512 --disk /home/user/VMs/mydisk.img --import
   note: this example might not work with selinux enforcement unless the user directory has correct authority, I went to /home/kvm

 So for us:
   # virt-install --name sassie-mobile --ram 8192 --vcpus 2 --bridge virbr0 --nographics --disk /home/kvm/sassie-web_mobileentropy.img --import

- virt-manager 
  - sometimes needs # dbus-uuidgen > /var/lib/dbus/machine-id
