experience's and issues with setting up cloudstack 4.3 and xenserver 6.2

[Ian Marshall]

Hi All

Openstack is now dumped as the preferred route to a private cloud solution.
Due to the issues with getting that installed, I need to get buy-in to
consider redeployment using Cloudstack.

We have got xenserver 6.2 running with EQLX as shared storage, so no issues
with these.

What I am struggling with is being able to list the benefits of CS over
just XS deployment. So if anyone has migrated from XS to CS due to
restrictions, plase advise what these were.

We need to be able to deploy across multiple sites and isolate 'projects'
and future expectations is SaaS/PaaS requirements as we diversify our
product ranges.

Regards
Ian

You can control a cluster of XS hosts using XenCenter but it may not be
scalable and manageable since you mention that in future you may need to
support multiple sites, need account/project management etc.

OpenStack is not a turn-key solution, I think it's more like a
toolkit/framework so it usually takes a lot of time. Apache CloudStack
on the other hand is a turn-key solution. You may google why people
chose CloudStack, see this for example:
http://insights.wired.com/profiles/blogs/why-cloudstack

As for list of features, some of the them are listed here:
http://cloudstack.apache.org/software/features.html


We need to be able to deploy across multiple sites and isolate 'projects'
and future expectations is SaaS/PaaS requirements as we diversify our
product ranges.


If it gives you some assurance, there are large number of hosting,
IaaS/Paas/SaaS companies using it:

Hi,

We have both standalone XS and ACS. Off the top of my head, the best few 
reasons to use ACS:
- user management and resource limit enforcement as well as tracking (eg we 
always seem to "lose"/misplace IPs with standalone HVs) and statistics
- HV agnostic (almost), we use XS and KVM
- network management
- virtual router more advanced features (VPN, load balancer etc)
- powerful API that can be used to automate stuff dramatically

With just XS the biggest PITA is tracking and setting network related info. 
With ACS I just give it a few IP and VLAN ranges and tell it to just use them.
Additionally, ACS has the concept of (resource limited) "projects" which 
multiple users can participate in. Not to mention additional goodies like 
cloud-init which can help with automation quite a bit (ie running user scripts 
at boot, setting SSH keys, root passwords etc).

It will change the way you work and once you get it off the ground and running, 
it will save you significant time and stress.

BUT, before you start using ACS in production: TEST, TEST, TEST! I can't stress 
this enough. 
IMHO cloud is hard, the software is big and complex and there are rough edges 
here and there, so take your time, get to know it; to know its weaknesses and 
strengths and use them appropriately.

StartupRoutingCommand gets wrong private_ip_address

[Gerolamo Valcamonica]

Hi, in my CS 4.3.0 (KVM) I just added a new host.

But it seems to me there is an issue in my configuration

Indeed, on DB, table "hosts", i have both private_ip_address and 
storage_ip_address with same IP and in log i can see:


[{"com.cloud.agent.api.StartupRoutingCommand":
[...]
 "privateIpAddress":"10.0.2.109",
 "privateMacAddress":"5e:63:56:74:5c:90",
 "privateNetmask":"255.255.255.0",
 "storageIpAddress":"10.0.2.109",
 "storageNetmask":"255.255.255.0",
 "storageMacAddress":"5e:63:56:74:5c:90",
[...]

I double checked host configuration and it seems to be ok

[...]
auto storage
iface storage inet static
address 10.0.2.109
netmask 255.255.255.0
network 10.0.2.0
broadcast 10.2.0.255

auto management
iface management inet static
address 10.0.1.109
netmask 255.255.255.0
network 10.0.1.0
broadcast 10.1.0.255
[...]

So, my question is:
where do management server get network configuration on hosts to answere 
to StartupRoutingCommand?

Re: Downloading templates from HTTPS

Had a look through them didn't find anything that seemed related.

Yes, I have ran into this many times before. 8080 is allowed too.

It would be nice to see the ports specified via a global settings variable.
I think I recall conversation about this on the list a very long time ago.

Re: Maximum template upload size

[Abhinandan Prateek]

max.template.iso.size global param defines the max size for template
upload.

Wrong timing when a Windows VM boots-up

[Indra Pramana]

Dear all,

We are using CloudStack 4.2.0 and KVM hypervisor. We are based in
Singapore, GMT +0800.

Recently we had some issues whenever a Windows-based guest VM under
CloudStack is being restarted, the time will move behind by 8 hours. For
example, if a VM was rebooted at 8am Singapore time, after reboot the clock
will show 12am Singapore time, which is the GMT equivalent. However, the
time zone is correctly stated as Singapore time, causing the whole system
clock to be 8 hour behind upon reboot and will stay that way until we
manually modify the time or synchronise with the Windows Internet time
server.

This issue may be related but it's for XenServer though. I am using KVM:

https://issues.apache.org/jira/browse/CLOUDSTACK-3443

Anyone knows how to fix the problem? The issue seems to be only affecting
Windows guests (both Windows servers 2008 and 2012) and do not affect Unix
guests.

Looking forward to your reply, thank you.

Cheers.

Re: Wrong timing when a Windows VM boots-up

[Abhinandan Prateek]

The issue fixed here CLOUDSTACK-3443 is about persisting time across
restarts.
>From your description it appears that the time that is saved is
consistently moving behind by 8-hours.
After stopping a affected VM from cloudstack you can look at the time
offset value in user_vm_details
That will give you insight into what is happening.

RE: 4.4 upgrade issues

[Sudha Ponnaganti]

Hi Carlos,

Were you able to resolve the following? Was your upgrade successful?

Thanks

Subject: 4.4 upgrade issues

I am trying out the upgrade instructions from 
http://docs.cloudstack.apache.org/projects/cloudstack-release-notes/en/4.3/rnotes.html#upgrade-from-4-1-x-to-4-3
 but going to 4.4 built from source today.

My setup: XenServer 6.0.2 Hosts, Management Server on Ubuntu 12.04, Primary and 
Secondary on NFS, Basic Network, no security groups

-
Notes on the docs:

8.4 - 8.6: This is only for hosts that use the cloudstack agent. Does not apply 
to KVM. In general this whole section does not do a good job of explaining what 
is on the MS vs the Hosts.

13: This fails on ubuntu because: cloudstack-sysvmadm sources 
/etc/rc.d/init.d/functions which does not exist on ubuntu/debian systems.

14: Copy vhf-util from where? Also the path 
/usr/share/cloudstack-common/scripts/vm/hypervisor/xenserver does not exist on 
the hosts so I am assuming this is on the MS, however the MS already has it 
since it is an upgrade and was put there by the original install.  Or is this a 
new version that needs to be grabbed from somewhere?

Other: earlier versions like 4.1 worked with JDK 1.6 current releases require 
1.7 but the Upgrade doc does not mention that.

Issues:

Saw the following in catalina.out, not sure if it is an issues:
Jun 27, 2014 5:28:42 PM org.apache.catalina.loader.WebappClassLoader 
validateJarFile
INFO: 
validateJarFile(/usr/share/cloudstack-management/webapps/client/WEB-INF/lib/servlet-api-2.5-20081211.jar)

javax/servlet/Servlet.class

Since the above script in step 13 did not work is it ok to do "xe vm-shutdown 
vm=." on each of the system vms?  Will CloudStack notice they are ton and start 
new ones?

Here are my log files (please note I stopped the service prior to capturing 
these logs in case you are wondering):
