Problems with Cloudstack 4.2.1 installation

[Giri Prasad]

Hello All,

 I have downloaded cloudstack 4.2.1 and trying to install it in my pc. The 
system config is : i3 processor, 8 gb ram, 500 gb hard disk, 1 nic card etc etc.

 I have installed java and maven as follows:

javac -version
javac 1.7.0_51

mvn --version
Apache Maven 3.1.1 (0728685237757ffbf44136acec0402957f723d9a; 2013-09-17 
20:52:22+0530)
Maven home: /usr/local/apache-maven/apache-maven-3.1.1
Java version: 1.7.0_51, vendor: Oracle Corporation
Java home: /usr/java/jdk1.7.0_51/jre
Default locale: en_US, platform encoding: UTF-8
OS name: "linux", version: "2.6.32-71.el6.x86_64", arch: "amd64", family: "unix"

I extracted the file apache-cloudstack-4.2.1-src.tar.bz2. And then did:
cd apache-cloudstack-4.2.1-src
mvn -P deps

  Here it errors out with the following as listed below. Can somebody provide 
insights. Thanks in advance for your valuable comments.

Regards,
D.Giriprasad

Your NIC link is flapping way too often and thats possibly whats causing
NFS to freak out. Try to narrow down the cause of the link flaps:

1) Force link speed settings
2) Change patch cords
3) Replace physical NIC
4) Try patching to another switch port
5) Check switch port speed settings


Hth.

issue with NIC of primary storage, well i can mount that filesystem manually

Issue seems to be strange because all necessary NFS ports are open in 
sysconfig/nfs file, iptables service is also off and both machines can ping 
each other successfully.

[abhisek basu]

Are we able to mount that NFS manually on the Xen Server?

NFS machine not responding, timed out issue

[Umair Azam]

I am facing an error while setting up cloud system, following issue 
arises when management server machine requests hypervisor to launch 
CP/SS VM's. After this request hypervisor tries to contact primary 
storage to access storage but that primary storage server doesn't 
responds, following are the logs from Xenserver hypervisor.

Lars,

Not sure how 4.0.2 works, but the theory is to take a snapshot of the 
ROOT volume, turn it into a template and launch new instances with this 
template.

Hello,

Citrix Xen related questions should probably be asked on the Citrix Xen
mailing lists :)

Actually; His question is regarding dom0 Sizing WITH His Configuration of
4GB RAM.

So it shouldn't be on Citirx Xen; it applies to CloudStack hardware
builders too or anyone running Apache CloudStack ON physical hardware (I'd
imagine most everybody is here on this mailing list).



By default, XenServer automatically tunes the dom0 settings during
installation.




IIRC, on a 4G system, ~768MB gets allocated to dom0


Here, we use the following sizing computation rules:

Rule:
dom0_mem = 502 + int(physical_mem * 0.0205)

You should always dedicate a fixed amount of RAM for Xen dom0.

This can be done by specifying "dom0_mem=512M,max:512M" option for the Xen
hypervisor (usually xen.gz) in grub.conf/menu.lst. This makes sure that the
initial amount of memory allocated for dom0 is 512 MB (note: Replace this
value with the amount of memory you want to allocate to dom0) and leaves
the rest of the host system's RAM available for other guests. See this
grub.conf example for GRUB1:

Re: Software licensing in the cloud

[Tim Mackey]

If you want to host Windows VMs you should really look into the Microsoft
Service Provider License Agreement (SPLA) program:
http://www.microsoft.com/hosting/en/us/licensing/splabenefits.aspx  From
the FAQ : "Microsoft SPLA is the only Microsoft Volume Licensing program
that allows Microsoft products to be used for commercial hosting."  If
you're hosting for internal users (e.g. devs) then existing licenses *may*
work, but I'd consult with your local Microsoft rep to be certain.

iirc there are other options available, but the reporting requirements can
be painful.

Re: Software licensing in the cloud

No, the license is per processor on a physical host. We use VMware, but
license each host for the instances. No Hyper-V here (just yet).

If you're worried about having to license every host in your cloud, you
could look at host tags and see if you can ensure instances built with
Windows Templates are on a certain subset of hosts.

Hope this helps.
