FINALLY a step ahead!!!! now, using a virtual management server, a virtual

6.0.2 host I have a Zone working!!!! Think that there is something wrong
with XCP, don't know what... anyway, now I have a new problem: the CentOS
builtin template reports status "Connection timeout" and ready "No", there
is no size reported. I checked and allowed on firewall any traffic from
both IP ranges used for public and private network, but no luck. Any idea?
I will start to work about this issue now...

Here it is... now I have created a host "virtual" running on a XCP 1.6
real host, modifying a mysql database parameter not to check for HVM
capacity.

Same problem, s-x-VM not starting.

Andrea,

That sounds right, could you upload your management log to pastebin.comfrom around the time
when you tried to add the host

Hi Andrea,

Sounds good to me. Still no luck running vms? Be advised that your
management interface in XS should be on "MGMT" network and reachable from
management server (I'm sure you checked thrice, just to be sure).

thx

Hallo.
On the host I have 2 ethernet NICs and 2 HBAs. In XenCenter I see them
as "network 0" and "network 1". In XenCenter I renamed "network 0" as
"MGMT"
and disabled the flag to automatically assign it to VMs, and "network
1" to "VNET", because I want it to be dedicated to VMs. Then, when
creating Physical Network, I gave it name VNET (globally) and assigned
to blue icon (internal management traffic) the MGMT label, and to
green icon (VMs
traffic) VNET label. I didn't include red icon (storage) because it
should be via HBAs. Are these settings wrong? I set primary storage as
"PreSetup"
and gave same SR-label used in XenCenter to identify it. Is it ok?


2013/1/2 Paul Angus <paul.angus@shapeblue.com<mailto:paul.angus@shapeblue.com>>

Hi Andrea,

It sounds like you need to label your network interfaces in on the
XenServer host and in CloudStack.

Its hard to read the early parts of the emails to see how many
interfaces you've got on your host. But if you have just the one
then rename it something with no spaces like 'if-cloud' its easiest
to do it with XenCenter.
Then you go to the GUI;  Infrastructure > YOUR_ZONE > Physical
Network.
Go
to each of the physical networks you have and set the 'XenServer
Traffic Label' for the management, storage, public and guest
networks to
'if-cloud'

Then add the host.

I have seen some hosts fail to add if the storage network isn't
explicitly
defined as a network too.

If you can include a link to your management server log it would help.

Hallo all and happy new year!
Today I tried again: management vm fresh, xenserver fresh and
updated
(but
still 6.0.2) with local storage, I closed wizard and before adding
zone etc. I configured option for system VMs on local storage. Then
added
zone,
pod, cluster, node... when adding node, some strange errors
regarding
agent
disconnected. From XenCenter I see that local storage has changed
name
with
"cloud stack bla bla bla" in description, but in management UI I
don't
see
any primary storage configured.
Ok, enough. New year, new life. If a product takes almost a month
for simply setup a trial and even now not works, maybe is time to
try
something
different. Maybe I'm unlucky and/or not capable of doing things, or
maybe CloudStack and guides are not so "turnkey" as they claim to
be. I don't know what else to do, just give up.

Remember the first step is to see if these steps are applicable
to
you.

Meaning in my case when I ran a find in xenserver console I was
not able to find the vhd-util tools.
Meaning there should be zero results for
find / -name "vhd-util"

If the patches are already applied (the steps won't help) you
might it them in /usr/sbin/vhd-util /opt/xensource/bin/vhd-util

Simple Tab should auto-fill it up You can cross verify from
XenCenter: Select Host-> General->UUID

1. In the CloudStack UI, Enable maintenance mode of the
zone you are
using.
2. In the CloudStack UI, Enable maintenance mode of the
host you are
using.
3. In the CloudStack UI, Delete the host.
4. In the XenCenter client, shutdown and delete the VMs
in the host (if not done already by CS).
5. In the XenCenter client,  in the Storage tab, right
click on the storage that maps to the primary storage
you have configured (my case it was NFS, if it is local
storage you can leave it) and
"Forget" it.
6. In the XenServer's console, run the following command
to
remove
the tag
 xe host-param-clear uuid=<hostid> param-name=tags
6. In the CloudStack UI, Add the host back 7. In the
CloudStack UI, Disable the maintenance mode of the zone.

hth,
Vijay

Hallo all! Thank you for your VERY appreciated help
and have happy new year!
Vijay, could you please explain a little more detailed
the
steps
to remove/cleanup the host? Sorry I don't know, for
example, what is a
"vbd"...
I'm quite new to Linux/Xen/Xenserver/CS, sorry for
asking
things
that
maybe
are very simple...


2012/12/28 Vijay Venkatachalam
<Vijay.Venkatachalam@citrix.com<mailto:Vijay.Venkatachalam@citrix.com>



I had the very same problem and resolved it quite
some-time
back.

**********************
Reason: The xenserver host did not contain
system-vm.iso, vhd-util
etc.
If you also could not find these files in your
xenserver read-on
**********************

A CS host tag had erroneously labeled/marked the
XenServer
was
already patched even though it was not patched. So
CS did not patch the host with the files
(vhd-util,....).

Solution:
Remove the tags in the host and re-add the host

Steps:
The following sequence of steps should help fix the
problem.
1. Remove the host
2. Cleanup the host as usual (clear vbd and any vms)
3.
Remove
cs tags of the host using the following command.
 xe host-param-clear uuid=<hostid> param-name=tags 4.
Add
the
host back

Subject: Re: Getting CRAZY for having a cloud

Hallo Sebastien,
thank you for your help.
I will try to put management log on the site you
provided.
I started using 4.0 version, tried 3.0 only
searching for a
solution.

Let's answer something:
1- yes management server is running
2- yes I defined zone, pod, cluster and host.
3- primary and secondary are defined and available.
4- I can mount NFS secondary storage and create
file inside it from host, primary is locally
available to host (HBA)
and
I can create a VM on it
using
XenCenter, so is online and working.
I also tried using NFS share for primary, or even
localstorage (enabling
global
config varable to use it for VMs).
5- zone is enabled.
6- VMs are NOT running. v-2-VM is in
starting/stopped state loop, while
if I
enable zone CS tries to create s-XX-VM, it fails,
it
deletes
it and try
again
creating a new one, increasing XX number of 1, in
an infinite
loop.
This is definitely my problem. If I look at
management log, it says that
my only
available host is in avoid set, so CS doesn't know
where to put VM and
fails. I
don't know WHY my host is in "avoid set": it has
22 GB of RAM,
200 GB of primary storage and 2 CPU quadcore. It
is a fresh install, formatted and
only
putted into a new pool as for installation
instructions. I used same
name for
network interfaces and primary storage. There must
be something wrong/missing in Xen/XCP setup, but
I'm not able to understand
what.
Is terribly frustrating...

Dear Andrea,

Very sorry things are not working out of the box
for
you.
If you can share your management server logs on
the list, maybe we can help better.
Use http://pastie.org/ for example, to avoid
your logs being stripped out of the email.

Since it's the holiday season, lots of folks are
taking a break and there are very few people
able to
help out.

You should use the 4.0 release which is the
first
official
Apache release, documented at
http://incubator.apache.org/cloudstack/downloads
.htm
l

Couple questions to understand where you are in
the setup
currently:

1-Is the management server running ?
2-Have you defined the zone/pod/cluster/host ?
3-Are primary and secondary storage defined and
available ?
4-Can you access primary and secondary storage
from your xen
host
?
5-Is the zone enabled ?
6-Are the system VMs running ?

Cheers,

-Sebastien

Hallo all. I tried to analyze log for myself:
found something wrong about storage, so I
disabled multipath, configured zoning on
fabric switches to permit only one path and
tried for XXXth time to setup all again from
scratch. No luck again.
Starting to believe is a lot of crap and
nothing else. I also tried installing CS 3.0.2
as "stable"
version, NO LUCK
AGAIN.
Tried using CentOS instead of Ubuntu, Nothing
again.
Ok,
I will take my LAST try using another physical
server with no SAN attached and using
local
storage as primary. If even this try will not
be ok, I'll give
up.
Wasted almost 3 weeks for obtaining... nothing.
Ok,
that
is a open source product, but I cannot believe
it to be SO INCREDIBLY IMPOSSIBLE to have
neither a trial setup up and
running.
If anyone believe I'm simply not able to
setup, I'm
here:
have a
PowerEdge
1950 DELL connected with a Brocade 200E to a
EMC
CX300.
I have another server for installing VMs for
management,
mysql, secondary storage and so on. I want to
use XCP/Xen as hypervisor, using a primary
storage on my
SAN
connected through HBAs. Give me just
instructions and I will follow
them.
That's all.

I don't know your physical setup, but if
you have two network
interfaces,
you should name them in XenCenter.

Example. In Xencenter, networking tab,
you see "Network
0"
and
"Network
1"
(don't remember exact names). Rename them
to be
"cloud-
private"
and "cloud-public" (for example). Then in
the
fancy
icons in setup
wizard (or
equivalent in infrastructure tab) put
those tags
in
private and
public
network.

That way CS maps vm's interfaces to the
right physical interfaces in
XS...
Also, please, upload your log to pastebin
or something similar to
check
up.

thx
