> Key: CLOUDSTACK-2115
> URL: https://issues.apache.org/jira/browse/CLOUDSTACK-2115
> Project: CloudStack
> Issue Type: Bug
> Security Level: Public(Anyone can view this level - this is the

> Components: XenServer
> Affects Versions: 4.2.0
> Environment: commit 81e1ba3bb406f9546f0d46ccbfa3fbbb35b762e2

> Steps to reproduce:
> 1. Create a basic zone
> 2. Add a XenServer 6.1 host to CloudStack
> Note : before adding, have changed the following
> - xe-switch-network-backend bridge
> - update sysctl.conf with the following
> # Disable *tables rules for bridge traffic to increase performance
> net.bridge.bridge-nf-call-iptables = 1
> net.bridge.bridge-nf-call-ip6tables = 0
> net.bridge.bridge-nf-call-arptables = 1
> - sysctl -p /etc/sysctl.conf
> Observations:
> (i) It failed to add the host with the following error

> (iv) the above output proves that though the network.conf has value "bridge",
> it is trying to fire OVS commands
> (v) After further debugging the /etc/xapi.d/plugins/vmops, found that while
> reading the network.conf, it ended up reading with a "\n" character which is
> making it picking the ovs commands.
> Here is the snippet of code :
> try:
> cmd = ['cat', '/etc/xensource/network.conf']
> result = util.pread2(cmd)
> except:
> return 'can not cat network.conf'
> if result.lower() == "bridge": ===> result.lower() is returning
> "bridge\n" hence this condition is failing, changing this to
> result.lower().strip() resolved the issue for me.
> try:
> cmd = ["brctl", "addbr", brName]
> txt = util.pread2(cmd)
> except:
> pass
> else:
> try:
> cmd = ["ovs-vsctl", "add-br", brName]
> txt = util.pread2(cmd)
> except:
> pass
> Attaching the management-server log, api.log, vmops script, SMlog to the bug.
