Hi everyone,
I was wondering how many of you are running CloudStack with a cluster of
management servers. I would think most of you, but it would be nice to hear
everyone voices. And do you get hosts going over their capacity limits?
We discovered that during the VM allocation, if you get a lot o
Hello Sounder,
1- What exactly is your requirement ? Are you going to deploy public or private
cloud.
2- what hypervisor do want to use, ( as per ur trail mail you are trying to
configure with Xenserver, you can use either XenServer 6.5 SP1 or XenServer 7.0
).

Are you proposing to add zookeeper as an optional requirement, Marc-Aurèle?
or just curator? and what is the decision mech of including it or not?

Hello, Marc-Aurele, I strongly believe that all mysql locks should be
removed in favour of truly DLM solution like Zookeeper. The performance of
3node ZK ensemble should be enough to hold up to 1000-2000 locks per second
and it helps to move to truly clustered MySQL like galera without single
maste
How hard is it to configure Zookeeper and get everything up and running?
BTW: what zookeeper would be managing? CloudStack management servers or
MySQL nodes?

Hi Thura,
afaik, yes.
But please keep in mind that I’m not at ACS guru, so there might be a way which
I’m not aware of.
For us it was a quite painless migration which was the most important thing.

Rafael,
- It's easy to configure and run ZK either in single node or cluster
- zookeeper should replace mysql locking mechanism used inside ACS code
(places where ACS locks tables or rows).
I don't think from the other size, that moving from MySQL locks to ZK locks
is easy and light and (even imp
so, how does that work?
I mean, instead of opening a transaction with the database and executing
locks, what do we need to do in the code?

We added ZK lock for fix this issue but we will remove all current locks in
ZK in favor of ZK one. The ZK lock is already encapsulated in a project
with an interface, but more work should be done to have a proper interface
for locks which could be implemented with the "tool" you want, either a DB
l
Do we have framework to do this kind of looking in ZK?
I mean, you said " create a new InterProcessSemaphoreMutex which handles
the locking mechanism.". This feels that we would have to continue opening
and closing this transaction manually, which is what causes a lot of our
headaches with transact
@rafael, yes there is a framework (curator), it's the link I posted in my
first message: https://curator.apache.org/curator-recipes/shared-lock.html
This framework helps handling all the complexity of ZK.
The ZK client stays connected all the time (as the DB connection pool), and
only one connecti
I did not check the link before. Sorry about that.
Reading some of the pages there, I see curator more like a client library
such as MySQL JDBC client.
When I mentioned framework, I was looking for something like Spring-data.
So, we could simply rely on the framework to manage connections and

I understand your point, but there isn't any "transaction" in ZK. The
transaction and commit stuff are really for DB and not part of ZK. All
entries (if you start writing data in some nodes) are versioned. For
example you could enforce that to overwrite a node value you must submit
the node data ha
Hello Jagdish,
What is source URL of template you're trying to register?
And when exactly this error is appearing? Immediately after you try to
register a template?

So, we would need to change every piece of code that opens and uses
connections and transactions to change to ZK model? I mean, to direct the
flow to ZK.

Sorry about the confusion. It's not going to replace the DB transactions in
the DAO way. Today we can say that there are 2 types of locks in CS, either
a pure transaction one, with the select for update which locks a row for
any operation by other threads, or a more programmatic one with the op_loc
Now, yes! Thanks for the clarification.

Hi Benjamin,
You would struggle to do this fully live (which I guess is what you mean by
“active”).
At a guess you would have to:
- disable zone
- delete your SSVM
- ensure no secondary storage operations are in play (e.g.new VMs being created
from new templates)
- umount secondary storage on b
All,
Thanks for your feedback.
We're reaching close to completion now. All smoketests are now passing on KVM,
XenServer and VMWare now. There are however few intermittent failures on VMware
being looked into. The rVR smoketests failures on VMware have been fixed as
well.

Hi Wido,
Thanks. I've verified, virtio-scsi seems to work for me. Qemu guest agent also
works, I was able to write poc code to get rid of patchviasocket.py as well.
Can you help review and test the PR?
Regards.

This error is occurring as soon as system VM gets downloaded and started

Hi,
Assuming your SSVM is up and running, have you tried to register any
another template? Did it work?
