2016-11-01[virtual envs] Switch to raw imagesMichael Polenchuk2-3/+3
* use raw devices instead of qcow2 * disable i/o caching, it reduces data copies and bus traffic * set native aio instead of thread based JIRA: FUEL-201 Change-Id: I8ac728cbb5be5948080fab8ae4d3d311e0a5c09c Signed-off-by: Michael Polenchuk <mpolenchuk@mirantis.com>
2016-10-10deploy: Fix: remove storage files explicitlyAlexandru Avadanii1-0/+2
Previous change [1] tried to move the responsibility of removing storage files (raw, iso) from our python scripts to libvirt. Although this works as expected for non-root invocations, like Armband deploys, it fails to remove raw files in Fuel@OPNFV deploys. Work around this by keeping both mechanisms (libvirt managed + python explicit handling).

Remove old disks through virsh instead of calling os.delete() methods so that the cleanup phase would succeed within a non-root setup.

2016-06-17deploy: add support for multiple bridgesJosep Puigdemont1-1/+2
deploy.py: Some Fuel VMs may need more than one network interface. To be able to provide that, we now allow the user to specify the "-b" paramter (bridge) multiple times, creating a new NIC for each one of them. The NICs are created in the same order as they are given in the command line. There is no change in behavior from earlier versions, pxebr will still be the default bridge if none is specified in the command line. deploy.sh: To reflect the new capabilities of deploy.py, we introduce the possibility to specify -B more than once in deploy.sh, and honor that when calling deploy.py. We also make it possible to specify a comma separated list of bridges, as in: -B br1,br2.

2016-06-17virtual_fuel: prepare class to allow multiple bridgesJosep Puigdemont1-8/+13
The VirtualFuel class has now two new methods: del_vm_nics: Deletes all interfaces from the VM. add_vm_nic: Adds a NIC to the VM, attached to the specified bridge. The following method has been deleted: set_vm_nic: implemented with the two new methods Apart from the deleted method, no functionality has been changed. This is just a small but necessary step towards adding support for configuring more than one NIC in the fuel VM.

2016-06-16virtual_fuel: add XML tree as attribute of VirtualFuelJosep Puigdemont1-7/+14
With this patch, the VM XML definition tree is an attribute of the object, this way it can be used by all methods without having to re-read the file. Methods added: update_vm_template_file: Flushes the contents of the in-memory XML representation of the VM to the backing file.

2016-06-15virtual_fuel: initial support for remote libvirtJosep Puigdemont1-3/+53
With this patch it should be possible to create a fuel VM on a remote libvirt server by properly defining the LIBVIRT_DEFAULT_URI [1] environment variable. If the variable is not defined, then there should be no percievable change in behaviour for the script. This patch introduces the ability to create volumes (images) on a remote libvirt host where the Fuel VM is to be deployed. For now the volumes are created by default in a pool named jenkins, but the idea is to allow this to be configured, probably in the POD's DHA file. Since all virsh commands honor LIBVIRT_DEFAULT_URI, we use this environment variable to detect wheter we should create a volume or not. The rationale being that the variable will only be set if the user wants to to do the VM deployment on a remote libvirt host. We need to create a volume because we can not rely on being able to access the remote server's file system directly. The images are then transferred to the libvirt host using virsh commands. All this could also be done using scp and a user directory on the host machine, but using pools allows us to take advantage of libvirt's policies and file permissions. CHANGE: when LIBVIRT_DEFAULT_URI is defined, the script will not check for the presence of the required PXE bridge. This will still be checked when the Fuel VM is started and the bridge not found, but this happens at a later point than it does today. CHANGE: before this patch, the file system image was named like the VM: vm_name.raw. This patch introduces a change and adds a timestamp suffix to the image: vm_name-timestamp.raw. This is so to avoid collisions with an image with the same name on the remote pool (two PODs may be using the same pool). It may also be useful to keep around old file system images. FIXME: This patch requires a pool named "jenkins" in the remote libvirt server, and it will fail if it is not present. This should be configurable. Notice though that we can still define LIBVIRT_DEFAULT_URI as "qemu:///system" to create the Fuel VM on the local host.
