Hi Jason Villalta,
Can you raise the ticket for the same. I can work on it if you assign to me.

Re: Change qcow disk cache=none
Posted by Jason Villalta <ja...@rubixnet.com>.
Yeah, I agree it may not be a setting you would want to show to
everyone. I saw there is a "template.properties" file for templates.
Is there a way to add it there so it is more under the hood than right
in the UI?

Re: Change qcow disk cache=none
Posted by Marcus Sorensen <sh...@gmail.com>.
Yes, lots of people will want it. For the longest time 'none' was fastest,
and still is except for some of the newer storage like RBD.
With a little more tinkering you could apply a different setting for
block,file,and network storage as they're already split out right there in
that file.
I worry a tiny bit though that such a feature won't be exposed to end
users, and will be a way of boosting performance at the cost of
reliability/safety. Users might be aware of the performance but not realize
that their cloud provider is running writeback. That's not a reason to not
have the feature, of course.

Re: Change qcow disk cache=none
Posted by Jason Villalta <ja...@rubixnet.com>.
One last question, Where do track features requests? I see the bug
tracker has moved so I am not sure where features should be entered?

Re: Change qcow disk cache=none
Posted by Jason Villalta <ja...@rubixnet.com>.
Thanks for all your help guys. I am on 4.0 currently. I will go the
agent route and see what I can do.
As for putting in the feature request. I will do that as well since I
am sure the more people use cloudstack the more people will run into
this. I really thing the UI is far superior experience.
On a side note, the VLAN stuff needs some better documentation around
configuration with KVM. Is there a place I can add some of my notes
once I get past this disk issue and test everything?

No, not today in a release of CloudStack.
What you however can do is download the source and build the agent
plugin. Assuming you use 4.0:
$ cd plugins/hypervisor/kvm
$ nano src/com/cloud/hypervisor/kvm/resource/LibvirtVMDef.java
$ mvn
Change the "none" setting to what you like.
Now you will have a .jar file in the "target" directory which you use to
replace the /usr/share/java/cloud-plugin-hypervisor-kvm.jar on your
production systems.

Re: Change qcow disk cache=none
Posted by Jason Villalta <ja...@rubixnet.com>.
Ideally it would be on the definition of the primary storage but only
applicable to KVM. If other hypervisors have different needs for the same
storage they should also have a way to defining those settings. I am not
sure what this would really look like yet as I am still just working to get
the system up and running.

Re: Change qcow disk cache=none
Posted by Jason Villalta <ja...@rubixnet.com>.
I have not seen this but you may be right. HA would probably work(meaning
a host fails and vms need to be restarted) but live migration may not. I
don't have enough harrdware to test this fully right now but will try to
get something setup.

Re: Change qcow disk cache=none
Posted by Jason Villalta <ja...@rubixnet.com>.
I read a few posts from people that seemed to say live migration would not
work at all if the cache= option was not set to none. That is just shadows
on the internet though, I have no first hand experience. Either way,

I did some more reading about this today and it doesn't actually mean
that migration won't work (or can't).
There is a slight chance that when using something like NFS in async
mode that writes are still in the page cache of the old hypervisor while
the guest is already on the new hypervisor.
This COULD lead to filesystem corruption inside the VM, but it doesn't
have to be that way.
If you use something like GFS or OCFS2 as a shared filesystem it will
work just fine. Same goes for when you use RBD (which doesn't use the
page cache at all).
I think you are only in "danger" when you are using async NFS or iSCSI,
although I'm not completely sure about the latter.

RE: Change qcow disk cache=none
Posted by Rajesh Battala <ra...@citrix.com>.
Hi Jason,
If cache=none on the disk then migration of the VM won't work right?.
I was going through RHEL link https://access.redhat.com/knowledge/docs/en-US/Red_Hat_Enterprise_Linux/6/html-single/Virtualization_Host_Configuration_and_Guest_Installation_Guide/index.html
Migration restrictions
============================
Because device assignment uses hardware on the specific host where the guest was started, migration and save/restore are not supported when device assignment is in use. If the guest operating system supports hot-plugging, assigned devices can be removed prior to the migration or save/restore operation to enable this feature.
Live migration is only possible between hosts with the same CPU type (that is, Intel to Intel or AMD to AMD only).
For live migration, both hosts must have the same value set for the No eXecution (NX) bit, either on or off.
For migration to work, cache=none must be specified for all block devices opened in write mode.
Warning
Failing to include the cache=none option can result in disk corruption.
Enabling this feature will have issues with HA right?
Thanks
Rajesh Battala

Yes I have gotten farther. I have the hard coded parameter changed and the system Proxy VM is running now but I am running into issues with the secondary storage vm. Troubleshooting that now.
As for the cache setting, I think that still need to be setup as a configurable option without a rebuild. Once I get the cloud fully functional I will have some time to contribute to this issue. For now I just need to get this up and running.

Exactly.
I brought this up about a week ago, see this thread:
http://markmail.org/thread/qmrod55gfmhwzot4
It shouldn't be a global property, it should be defined per storage pool, or
even better, per disk offering.
Right now we are talking about the cache setting, but tomorrow it could be a
different setting.

RE: Change qcow disk cache=none
Posted by Rajesh Battala <ra...@citrix.com>.
Sounds great.
How are you planning to implement the cache config value. From GC settings or as part of offering or a dynamic changeable param to the VM.
Thanks

Yes I have gotten farther. I have the hard coded parameter changed and the system Proxy VM is running now but I am running into issues with the secondary storage vm. Troubleshooting that now.
As for the cache setting, I think that still need to be setup as a configurable option without a rebuild. Once I get the cloud fully functional I will have some time to contribute to this issue. For now I just need to get this up and running.
Thanks,

Re: Change qcow disk cache=none

I tried this method to build 4.0.0 and I get 3 failed dependencies.
Does something in git need to be updated with different paths?

Re: Change qcow disk cache=none
Posted by Marcus Sorensen <sh...@gmail.com>.
If you just want to change 'none' to 'writeback' or something like that:
git clone https://git-wip-us.apache.org/repos/asf/incubator-cloudstack.git
cd incubator-cloudstack
git checkout 4.0
vi ./plugins/hypervisors/kvm/src/com/cloud/hypervisor/kvm/resource/LibvirtVMDef.java
# look for the one occurrence of 'none' in this file and change it as
you see fit
Then build your packages
(https://cwiki.apache.org/CLOUDSTACK/building-with-maven.html#BuildingwithMaven-BuildingRPMpackages)
mvn install -P deps && ./waf rpm
or
mvn package -P deb
If you want the fully configurable experience from GUI, with per
disk-offering settings, then you'd open the request, and it may make
it into 4.2 in May. Or you could pull the git repo and see if the
feature applies to 4.1 and build your own packages in a month or so
when the feature branch is ready.

So is there anyway to make this work today or will I have to wait
until this is properly implemented? This may mean I need to take
another look at openstack or opennebula and switch back.

Exactly.
I brought this up about a week ago, see this thread:
http://markmail.org/thread/qmrod55gfmhwzot4
It shouldn't be a global property, it should be defined per storage
pool, or even better, per disk offering.
Right now we are talking about the cache setting, but tomorrow it could
be a different setting.

Re: Change qcow disk cache=none

Is there any way easy way to make this setting dependent on the
storage definition? For example some primary storage may need this
set to one value such as cache=writeback such as with the case of ZFS,
GlusterFS, CEPH. Then other storage may want a different setting such
as cache=writethough or none which is the case with a local ext4
storage or NFS.

RE: Change qcow disk cache=none
Posted by Rajesh Battala <ra...@citrix.com>.
Hi Jason Villalta,
In LibvirtVmDef.java, there is DiskDef class , get the cache value from the Global config, while constructing the xml in the override method the class toString() specify the cache value, currently it is using "none".
NOTE: whenever there is change in GC value, MS should restart for the value to take effect.
