Hi Prasanna,

  That page isn't fully correct regarding MariaDB.  Please see:

It also facilitates XenServer's native snapshot capibility, and works
flawlessly.
I have no idea why the release notes and admin guide ONLY mention VMware,
as opposed to the wiki. :(

RE: CS 4.2 VM snapshot is not enabled for hypervisor type: KVM

Hi,

Instance Snapshot is only supported on VMWare. It uses VMWare native snapshot 
facility.
Please refer 
http://cloudstack.apache.org/docs/en-US/Apache_CloudStack/4.2.0/html/Admin_Guide/vm-snapshots.html

Thanks,
Sanjeev

Hi Sebastien,

I was not able to solve the snapshot issue, I can take a snapshot of a disk but 
not of the "instance",  I still get the "VM snapshot is not enabled for 
hypervisor type: KVM"

I enabled KVM snapshot in Global Settings, someone suggested to turn off the

mshost table after upgrade from 4.1.0 to 4.1.1

[Carlos Reategui]

Hi,
Can someone that has updated from 4.1.0 to 4.1.1 (ideally with XenServer
hosts) run the following queries in their db:

select msid, state, version, service_port, removed from mshost;
select ms.msid, ms.version as ms_version, h.version as host_version, count(
h.id) from mshost ms, host h where ms.msid=h.mgmt_server_id;

On my db I see the following:
mysql> select msid, state, version, service_port, removed from mshost;
+-+---+-+--+-+
| msid| state | version | service_port | removed |
+-+---+-+--+-+
| 233845174730255 | Up| 4.1.0   | 9090 | NULL|
| 233845174730253 | Up| 4.1.1   | 9090 | NULL|
+-+---+-+--+-+
2 rows in set (0.00 sec)

mysql> select ms.msid, ms.version as ms_version, h.version as host_version,
count(h.id) from mshost ms, host h where ms.msid=h.mgmt_server_id;
+-++--+-+
| msid| ms_version | host_version | count(h.id) |
+-++--+-+
| 233845174730255 | 4.1.0  | 4.1.0|   2 |
+-++--+-+
1 row in set (0.00 sec)

I don't think this is right and I am trying to see what it looks like for
others that have done the upgrade from 4.1.0 to 4.1.1.  I believe the 4.1.0
msid should have a date in there indicating that it is no longer active and
hosts in the host table should be linked to the 4.1.1 msid not the 4.1.0.
 As well as have there version updated to 4.1.1.

For the dev list guys, would it me ok for the to edit these values and see
if that fixes my broken installation?  Also what should I do with entries
in the tables like op_ha_work, op_it_work and storage_pool_work.  I am
guessing I also would need to update the later also but not sure about the
first 2.

thank you
Carlos

RE: VMware vCloud to CloudStack migration

Sean,

Like you mentioned, there is something in OVF that is of bound.

Perhaps logs will reveal more info? They way I usually address this, I take a 
good know working OVF, and inject my VMDK or just rename VMDK to match what you 
have.

OVAs are create with tar command, so you can easily tar it up again (don't 
remember if gzip compression was used, I think it did).

RE: Multi-master MySQL Setup

[Alexey Zilber]

You need to examine your reasons for needing master-master replication.  If
it's write performance and not a lot of data, then MariaDB's Galera
implementation is good.

If you have a lot of data then I suggest using the TokuDb engine.  It's
available native as of MariaDB 5.5.33a and also via Tokutek.com with a
newer engine and more features.   You should be able to get much better
write performance with it over InnoDb. Using ssd drives with it also makes
a huge difference.  No need to deal with multi-master.

That said, MariaDB 10 will support multi-master natively with global
replication tracking,  etc.

RE: Multi-master MySQL Setup

Look into continuent.com solutions, specifically tungsten replicator.

If you have a budget involved, enterprise version of tungsten replicator can do 
master-master and handle conflicts. The pricing is not outrageous either.

Re: Multi-master MySQL Setup

[Marty Sweet]

The issue with plain MySQL replication (espically in master-master) is that
a failed query will stop replication. A good example of this is when an
record is added onto each master at the same time (within a second), say a
new record which gets the same primary key and replication will stop, on
both hosts. That then leaves a split brain situation when you have one
master writing its own data and another writing to itself, all with
identical primary keys. Absolute nightmare. This can how ever be migrated
with the methods the OP mentioned (I assume - but don't have experience of).

I don't think file curroption is much of an issue with DRDB, but you can
only have one host write to it at anyone time (limitation of file system
used), which makes the master-slave or master-backup setup ideal when
coupled with HA service management software such as Pacemaker. You then
have the database files in both places without the dreaded MySQL
replication stories.

I think the main question lyes with if the cloud admin wants a
simple redundant setup or a load balanced service - it may also we worth
writing some documentation for this to help future installations, although
they will have to be detailed.

I have never used Percona/MariaDB, does it resolve the master-master issues
I mentioned earlier?

RE: Multi-master MySQL Setup

[Adrian Lewis]

Seems like the Percona solution also uses Galera for their multi-master
cluster. Starting to wonder whether to go MariaDB-Galera now. Tempted just
to leave it as master slave replicated on MySQL though. Scale really not
an issue right now. Ho hum, fun to be had if I had the time to play.

Assuming no Galera (with either MySQL/Percona/MariaDB) and just using
Centos version of MySQL - does anyone have any input as to whether to go
for replicating between two hosts using DRBD vs native MySQL replication?
I get the impression that MySQL replication is an eventually-consistent
near-realtime kind of replication whereas DRBD can be set to be completely
synchronous replication. MySQL replication just seems a lot less fiddly
than using DRBD and DRBD would replicate file corruption that MySQL
replication would be largely safe from.

They are using Galera I mentioned previously. It works with MariaDB

Re: Can't destroy system VMs

[Carlos Reategui]

Hi Daan,

The mshost thing I mentioned previously has been bugging me and as I look
through the db I think I have a problem here.  I am guessing I have a
botched 4.1.0 to 4.1.1 upgrade that I did not notice when I shut things
down.

The mshost table is showing 2 management servers that are supposedly on the
same machine listening on the same port which is not really possible.  So
really only one of the 2 is up (I believe that would be the 4.1.1 version).
The logs do seem to indicate something along those lines where the 2
management servers are failing to communicate with each other.

If I look at the host table I see my 2 hosts but they say they are on
version 4.1.0 and are pointing to management server id of the 4.1.0 line in
the mshost table.

I am wondering if this is the problem and why their is no communication to
my hosts from the management server.

Anyone know the schema well enough to help me update some stuff and recover
my installation?  Would an upgrade to 4.2 possibly cleanup my DB?

thanks,
Carlos

Re: Can't destroy system VMs

[Carlos Reategui]

Hi Daan,

I have been looking through my logs and can't figure out why the ssvm does
not want to start.

Here is a link to my latest logs:
http://reategui.com/cloudstack/management-server-131105.log

Maybe someone else can spot something.

There is nothing on either the XenServer hosts logs.

thanks,
Carlos

Re: domains/subdomains headaches

[Nitin Mehta]

I don¹t think CS has that functionality at the moment. I am guessing RBAC
work might factor that.
That said there is a workaround of adding the accounts you want the
template to be visible through updateTemplatePermissions API.
See that works for you

RE: Multi-master MySQL Setup

[Adrian Lewis]

Hi Marty/Nux!,

Thanks for the feedback - sounds like multi-master is not a good thing
then! Load will likely be very small for at least the next 6 months but I
figured that it was one of those things that could be set easily now
(still setting up) that I might appreciate later.

Based on both your responses, I think I'll just leave it well alone! Need
to get to grips with pacemaker/corosync anyway for other reasons so I'll
just try that with either DRBD replication or MySQL replication.

Cheers,

Adrian

Others may have had more success with this but from experience of MySQL in
multi-master setups I would avoid this entirely.

A common setup is using DRDB to provide a master/slave:
Management 1 (MySQL Master) w/ virtual IP Management 2 (MySQL Slave)

HA IP Address (for agents/services requiring DB write) which is assigned
to the master (using Pacemaker).

You can then send web management client to the HA IP Address as well.

It may be worth considering if you need load balancing, depending on your
setup - what loads are you experiencing?

VMware vCloud to CloudStack migration

[Sean Hamilton]

Hi Guys,

I have a user that is trying to export an instance from vCloud so that they
can import into CloudStack. They've exported the .ova file which contains:
- .ovf file
- .vmdk file

When they upload the template they get a deployment fail, I think that this
is due to the metadata in the .ovf file. I've seen specific entries before
on VirtualBox to CloudStack migrations but can't figure this one out.

Are there any recommendations or best practises on this at all?

Thanks,
Sean

Ok, as I have written yesterday I have tried to configure a router.
So I put inside my router vlan 100, 200 and 300 (obviously I have already
vlan 100 working because without it I cannot access the cloudstack server).
So:

- vlan 100: my router has 10.1.0.1 
- vlan 200: what I put in my router? tried 10.1.1.1 but it did not work
- vlan 300: what I put in my router? tried 10.1.1.1 but it did not work

I could not find anything in docs that explain me clearly what really
cloudstack does and how to debug it.

Thanks again for your precious help,
Mario

Re: Help needed for ip setup

[Marty Sweet]

Hi Mario,

Are you tagging VLANS to this host?
If so, is the switch connected to a Layer 3 switch, which you can then
configure as a router to route the traffic from your cloud VLANS to your
local working network.

Vlan bridges are added when network/vms are created.

I hope that makes sense,

Marty

RE: CS 4.2 Virtual Router HA

[Geoff Higginbottom]

Jerry,

CloudStack will try and keep the two Virtual Routers separate, running on 
different Hosts/Clusters/PODs to help with HA, as long as there are suitable 
resources available.

When using the Redundant Router feature, the two VRs run in an Active/Passive 
mode, and both are also treated as HA.  If the admin destroys the Active node, 
the Passive node immediately takes over and becomes Active, the destroyed node 
then gets recreated and comes back online as a new Passive node.

Hi Motty,

All you need to do is create a new Network Offering with the same settings as 
the 'DefaultIsolatedNetworkOfferingWithSourceNatService', but also enable the 
'Redundant Router Capability.  This will then give you a pair of Virtual

[ANNOUNCE] OCCI Interface

[sebgoa]

Hi,

I am pleased to announce an OGF OCCI interface to CloudStack.

Isaac Chiang contributed back to our ruby client and forked rOCCI-server to 
make this happen. Many thanks to him.

I wrote about it here:
http://buildacloud.org/blog/296-occi-interface-to-cloudstack.html

OCCI is one of the two cloud standards (with CIMI from DMTF).
It is very important for CloudStack has it finally brings an official industry 
standard API to our software.

If you want to help with CIMI, ping me.

Cheers,

-Sebastien

Re: Can't destroy system VMs

[Daan Hoogland]

Carlos,

It makes no sense trying to start the vms if not the ssvm is started first.

I would say stop the system, clear the logs and start again. Then
analyse the logs to see what is wrong with the secondary storage vm.

Re: Using XenServer-6.2.0 and CloudStack-4.2.0

Hi Vladimir,

XenServer 6.2 ISO which is made available at xenserver.org is fully supported
by ACS 4.2. You should have no problems with it.

Also, according to 
http://xenserver.org/open-source-virtualization-download.html,
the bits are identical to those directly available from Citrix website.

Regards.
