 Review comment:
   @khos2ow I think you're missing a big point and I'm wondering how you're 
testing your changes. This script runs inside CloudStack's systemvmtemplate 
that is based on Debian 9 for 4.11+. For the change in 4.11 branch, the 
test/changes must be performed on Debian9 based guest vm only. In our built 
template, the path to `xenstore-read` is at `/usr/bin`. Regarding the 
`virt-what` comment, again the version of virt-what is specific to the Debian 9 
based systemvmtemplate that would return xen-hvm in my tests across XenServer 
6.5-7.x versions. I'll therefore keep my changes that are tested against 4.11 
systemvmtemplate. Temporarily hosted here are latest 4.11 templates if you want 
to try them: https://lab.yadav.cloud/systemvmtemplates/4.11/

 Review comment:
   That's strange, I really don't know what's going on. I just checked dozens 
of random VMs, on various Xenserver version (7.x.x+ though) and all of them had 
`xenstore-read` in both places! I guess using `/usr/bin` would be safer. or 
even check both places then log an error?
   BTW I wrote a comment on your PR as well.

 Review comment:
   @khos2ow in 4.11 systemvmtemplate, the xenstore-read is at /usr/bin, can you 
check/comment why /usr/sbin was used? I've however, fixed this blocker in the 
stabilization PR:

   @rafaelweingartner I will. The reason for it's not done yet was that we 
wanted to partially upgrade Xen cluster and do one round of functional test and 
then fully upgrade the cluster and then re-run iperf tests.

   @pdion891 do you have a feedback regarding the result of tests conducted by 
you guys?
   I have used this in a test environment to check the backwards compatibility 
with system VMs PV, and everything is ok with this use case.

   @syed awesome, thanks!
   
   @pdion891 yes that's correct, it uses Debian 9 since 4.11. Would you say 
there will be a lot of difference - in terms of performance - between Debian 7 
and 9? In terms of functionality should be fine though.

   @rafaelweingartner  for the load test, I want to make sure that on a heavily 
loaded xenserver, will not affect data availability from xenstore at the 
creation of a VR. We are also running some benchmark on the VR between HVM and 
PV to see if moving to HVM will improve VR performance.
   
   @khos2ow,  in 4.11 systemvm is using Debian 9 correct ? if so, it's not what 
we are currently testing, we are currently focusing on the 4.10 template Debian 
7

`cloud-early-config` will be updated with new code.

   That is what I would expect. If you take a look at the millstone for the 
next release of 4.11, you can see that it is 4.11.1.
   
   @syed, so the scripts all come from systemvm.iso. That is great, then we do 
not need to built a new one and deal with all of the bureaucracy that it would 
require.

   It got changed in 6ffbce6. May be it was supposed to be `4.11.1.0-SNAPSHOT`?

   Hmm..Then, I think there is something wrong. As far as I know, the version 
format is x.y.z.s, where x.y are used to identify the major version; .z is the 
minor, and .s is the security version bit (in case we have a security version 
for the x.y.z).

   Correct. The new template will be mandatory only if they are working against 
XenServer though, but we need to generate one anyway.
   BTW, the POM version is `4.11.0.1-SNAPSHOT` and not `4.11.1.0-SNAPSHOT`, if 
that needs to be fixed.

   4.11 already requires a new template, right? So, people that upgraded to it 
already had to install a new one given the changes that are in 4.11. Now, we 
would need to create a new one for 4.11.1.0 , given the changes in this PR, 
right?

   I don't think we need a template for 4.11.0.0 (because there's no java code 
and cloud-early-config to handle it) rather than only new template for 4.11.0.1.

   I see you targeted the PR against 4.11 branch. So, a system VM for 4.11, and 
another one for 4.11.1.

   @khos2ow and @pdion891 thanks for this one!
   BTW, when you mean a load test, you are only talking about reboot/reset? are 
you planning a load test in the sense of multiple VRs in the same host, to see 
how XenServer will deal with all of them using this approach?

   BTW we are doing some test of this on our side, to make sure we keep support 
of VR running as PV on legacy deployments and support now default HVM VR on 
xenserver 7.1+...
   
   So far the xenstore method work well but still need few tests under high 
workload, VR reboot, reset,...  we should have more news in a week, our QA will 
only focus on xenserver 7.1 including 7.1.1(cumulative updates)

 Review comment:
   What I meant is that, in a Web API drive system such as ACS, everything is 
synchronous (or almost everything). Therefore, the 1 nanoseconds of improvement 
that the use of this IF conditional can bring is negligible. This means that 
the code (the code used to create this optimization) is not worth it (in my 
perspective).
   
   I normally see people using this approach of checking log level before 
logging when creating log messages using String.format, which uses quite some 
processing. However, even in those cases, I do not see much need to check the 
log level before logging (in most cases).
   
   I just commented to give some context on the use of this isEnabled 
method. The only time I used this approach of checking log level was when I 
developed some standalone optimization algorithms that had a time constraint to 
be executed. Therefore, there was no space to waste clock cycles creating a log 
message that is not going to be used.
   
   In summary; if I were coding, I would not use it. However, we have these 
things spread all over our code base. I normally remove them, but if you want 
to use, the choice is yours.

 Review comment:
   In this type of system such as ACS, I believe it is worth the cost of a tiny 
bit of more processing to remove an If statement. Specially in cases such as 
this one, when you already have others IFs where this one is nested.

   Could you please move the `vm-data/cloudstack/init` string into a class 
constant.
