XenServer/verify/How to verify the deployment of MOS+XS by using rally
Citrix has released XenServer plugin for Fuel, so that we can deploy Openstack on XenServer by using Mirantis Fuel. We can search on the page of mirantis Fuel Plugin Catalog to get this plugin. This page is to show how to run tempest in the deployment of "MOS+XS" to do verification by using the benchmarking tool - Rally.

The first step is to setup a lab installed with Mirrantis Openstack by using fuel. You can follow the following blog to setup the environment on a single xenserver:

As Fuel 7 base has a bug(https://bugs.launchpad.net/fuel/+bug/1503638), we can't set Nova-network without vlan tag. So if you use "FlatDHCP Manager" on Fuel 7, please follow the following link to apply Mirantis OpenStack 7.0 Maintenance Update 1. https://docs.mirantis.com/openstack/fuel/fuel-7.0/maintenance-updates.html
Or we need a way to tag the VM vif. The following script can be used for that purpose. br=$(xe network-list name-label=br100 params=bridge minimal=true) oldports=$(ovs-vsctl -- list-ports $br); while :; do ps=$(ovs-vsctl -- list-ports $br); for p in $ps; do if echo $oldports | grep $p>/dev/null; then :; else echo "set tag for $p"; ovs-vsctl -- set port $p tag=103; fi; done;oldports=$ps; sleep 1; done

Ensure DNS server is available in the fuelmenu: the fuel master node depends on the configured DNS to resolve domain names and it runs a DNS service which is depended by the other Openstack Slave nodes. So please make sure the DNS server is available on the fuel master node. Otherwise it will meet the repo unavailable error in network configuration verificattion step.

As the tempest test will consume much disk space with cinder testing, please ensure the volume of cinder has enough space. Suggest its size is bigger than 50GB.

As the rally test will be done automatically, we need a pre-generated key and certificate to enable TLS for OpenStack public endpoints. To make it simpler, let's disable the "Public TLS" when set up the testing environments with FUEL GUI.

Fix for console log file generation and rotation to pass console log relative cases Bug: https://bugs.launchpad.net/fuel-plugin-xenserver/+bug/1521483 Workaround: wget --no-check-certificate https://raw.githubusercontent.com/openstack/nova/master/tools/xenserver/rotate_xen_guest_logs.sh chmod +x rotate_xen_guest_logs.sh echo '* * * * * /root/rotate_xen_guest_logs.sh' >/var/spool/cron/root

By default, nova quota function is disabled. Please enable it firstly to pass the relative cases On Controller node, change fuel plugin to set /etc/nova/nova.conf with quota_driver=nova.quota.DBQuotaDriver; restart the relative services; And then update DB to trigger quota usage refresh: https://review.openstack.org/#/c/170821/9/pages/operations/how-to-enable-nova-quota.rst,unified

Install Rally wget -q -O- https://raw.githubusercontent.com/openstack/rally/master/install_rally.sh | bash Note: It may failed at the first time due to lack of some required packages. Just follow the instruction from the error messages to install all of the needed packages. And then re-install Rally.

The default image is with the disk_format as qcow2 which is not supported by XenServer. So we need to specify the image url, disk format and container format for the vhd image. Due to the following bug, we need to cherry pick the fixing patch to make the field of cirros_img_url to take effective. https://bugs.launchpad.net/rally/+bug/1530075 https://review.openstack.org/#/c/262636/

"admin" is the default swift operator role created by the way applied in the Openstack deployment step; but the rally default conf is Member. So it will have role mismatching issue. We need change the rally conf as what's showing by the following snapshot.
