Cloudstack with iscsi storage

[rammohan ganapavarapu]

Hi,

I am trying to setup a private cloud using cloudstack with ISCSI storage as
primary storage, my

1. Do i need to create a filesystem on top of iscsi lun to use it as
primary storage or just need to present a raw lun to hyperviser?

2. If i have multiple hosts as VM hosts, do i need to present iscsi luns on
all those hosts or one storage hosts should be fine? can i use this storage
host as VM host?

3. I have storage on different network, so does management servers or
control server neeeds to have access to storage network?

Thanks,
Ram

The network label I am using is "dvSwitch-test,602,vmwaredvs" Using a standard 
vSwitch works fine. e.g. vSwitch1,602,vmwaresvs  Any ideas?

Re: XML error: missing pool source name element

[Willard Rathjen]

uuidgen the uuid fields (There are two) in the agent.properties file. and you 
should be good to go. The storage pools will get configured in KVM when you 
pull the host into CS.

Looking at LibvirtStorageAdaptor.java it looks like it’s failing when dealing 
with the storage pool.

can you paste the agent config: /etc/cloudstack/agent/agent.properties



And the output of the following commands:

$ virsh pool-list

$ virsh pool-info

Hi All,

I am trying to setup an "All-in-One" CloudStack install on CentOS 6.5.

When I start the agent I get this error in the log file:

ERROR [kvm.storage.LibvirtStorageAdaptor] (Agent-Handler-1:null)
org.libvirt.LibvirtException:

Any idea what this means and how to fix it?

Thanks,

Hi ,

This program runs on CloudStack management server and listen for the

Pretty neat, but have you looked at this?
https://cloudstack.apache.org/docs/en-US/Apache_CloudStack/4.1.0/html/Admin_Guide/events.html

It sounds like you are not using that facility which to me (non-dev) 
seems more elegant.

On event (new host deployed) program calls CloudStack API and gets list of

to my knowledge it is not distro specific. We are using that on Ubuntu

that IF condition works.

CloudStack-BIND dns integration

Hi ,

I made a small python program that  solves DNS integration issues between
CloudStack VR's DNS service and BIND DNS.

network has own sub-domain) (IMHO the best way fro naming instances in
CloudStack)
How it works:
This program runs on CloudStack management server and listen for the new vm
deployment using CloudStack catalina.out log.
On event (new host deployed) program calls CloudStack API and gets list of
Networks and list of VM. Using theses lists and preconfigured domain
settings it creates the zone file for BIND, push it to server and refresh
BIND
The source code for the event driven version on GitHub:

Template creation hanging

[Jonathan Gowar]

Hi,

  Created an instance, shut it down to create a template from; which
I've successfully done before.

This time, the process has hung, with these messages in the logs:-

2014-04-16 16:04:42,891 WARN  [o.a.c.f.j.i.AsyncJobMonitor]
(Timer-1:ctx-ccdc1f1f) Task (job-1158) has been pending for 694 seconds

How can I wipe away pending template creations, and start again?

Jon

Vmware 5.5 dvSwitch support.

global settings. The management server has been restarted.


The network label I am using is "dvSwitch-test,602,vmwaredvs" Using a standard 
vSwitch works fine. e.g. vSwitch1,602,vmwaresvs  Any ideas?

Hi,

  I need to do change the hostname as according to CS, but don't know
about cloud-init scripts.

What machine would a script to set the hostname sit on?  Also, it seems
the attachments are missing?

Is this documented anywhere, to give me a better understand.

Thanks,
Jon

Sure ;)
On my Ubuntu 12.04 templates I use two scripts.
One to change the root password, and the other to change the host name 
according to the one that was defined on CS.
one is in "/etc/init.d/", and it is called cloud-set-guest-password. (The 
script is attached).

and the second one is in "tc/dhcp/dhclient-exit-hooks.d/", so it is called 
right after the DHCP finishes its job. And its name is setHostName. (Also 
attached)

Re: Ubuntu instances + cloud-init

[Rafael Weingartner]

Sure ;)
On my Ubuntu 12.04 templates I use two scripts.
One to change the root password, and the other to change the host name
according to the one that was defined on CS.
one is in "/etc/init.d/", and it is called cloud-set-guest-password. (The
script is attached).

and the second one is in "tc/dhcp/dhclient-exit-hooks.d/", so it is called
right after the DHCP finishes its job. And its name is setHostName. (Also
attached)

Sandeep,

This looks like a network configuration issue to me. Looking at your routing
table, the 2 DNS servers having the IPs 10.4.21.4 and 103.15.60.4 have a
host specific route using the eth1 device:

> 10.4.21.4   10.4.6.1255.255.255.255 UGH   0  00 eth1
> 103.15.60.4 10.4.6.1255.255.255.255 UGH   0  00 eth1



Would you know which physical interface on the hypervisor is bridged to
SSVM’s eth1? You can run the “brctl show” command on the hypervisor to get this
information.

A Virtual Machine’s networking is very different from the physical
hosts networking. A physical bridge has to configured with the
right label to assist cloudstack in mapping a VMs interface(s)
to the right physical interface.

If the mapping is incorrect, then networking will generally fail.
