> On VR restart/start CS sends the configuration to VR via vmops 'createFileInDomr' method.
The createFileInDomr method receives the content and create temp file in xenserver and push
this file to VR using SCP.
> When the VR configuration is more than ARG_MAX size of the xenserver host then it command
got failed.
> The below is the command to get the ARG_MAX value in the host.
> #getconf ARG_MAX

> Reproducing steps:
> 1. create an isolated network and deploy vm in that network.
> 2. Create large size configuration to VR by creating more number of VMs or configure
more set of network rules on the network.
> 3. After this restart the VR. On starting the VR CS sends the configuration to VR, You
can see the configuration in MS log.
>  Error: callHostPlugin failed for cmd: createFileInDomr with args
