Re: Experience with clustered/shared filesystems based on SAN storage on KVM?
Hi Mauro, what would you like to store on the clustered file system ? If you want use it for virtual machine disks I think nfs is a good solution. Clustered file system could be used if your virtualization nodes have a lot of disks. I usually I prefer use a nas or a San. If you have a San you can use iscsi with clustered logical volumes. Each logical volume can host a virtual machine volume and clustered lvm can handle locks.

RE: cloudstack kvm openvswitch

Now we have to verify if a gre tunnel is automatically created with an ovs network offering. We are trying with centos 6.6 and ovs 2.3.1: we suggest to leave the ovs kernel module supplied by centos because the ovs 2.3.1 module causes some kernel panics.

Documentation said that is 1.9 (if you patch it), but I have successfully used 2.x versions without errors. Think documentation is outdated. Still I was not sure that it is properly supported at CS level. 2. There are number of problems with plugin activation since 4.4 version. Look here for example: https://issues.apache.org/jira/browse/CLOUDSTACK-7446 3. I've been using OVS with VLAN isolation and have seen it is working with CS properly. What does exactly do plugin activation - don't know. May be plugin should put some more network offers. But since it was broken I was not able to test it. 4. Didn't try GRE.

cloudstack 4.5.1 ovs on kvm
Hi guys, We read carefully cloudstack documentation to activate gre isolation on kvm nodes. First issue we found is: ovs does not appear in service network provider. Second issue we found : the gre tunnel betweten kvm nodes is not automatically created also after migrating a vm ; so a vm on first node cannot ping a vm on second node. We solved manually creating gre tunnel between kvm nodes. Any suggestion is accepted. Regards Ignazio and Gianpiero

Re: KVM + VMware (and ceph)
Hi all, I would like to make the same configuration but using ISCSI instead of NFS. I could set two phisical servers(for high availability) with ubuntu and lio iscsi target. On the ceph side this servers will use rbd and on the vmware side they will exports rbd disks as LUNs. I would verify if there will be a performance degradation vs kvm rbd integration. Someone has tested this configuration yet ? Regards 2014-06-11 10:38 GMT+02:00 Andrei Mikhailovsky and...@arhont.com: Hi guys, This is what I've done to get a failover nfs storage solution with XenServer on top of ceph. 1. Setup two rbd volumes (one for vm images and another one for shared nfs state folder). Make sure you disable rbd caching on the nfs servers. 2. Install ucarp package on two servers which will be the nfs servers. These servers will need to have access to the rbd volumes that you've set up in step 1. 3. Configure ucarp to be master/slave on the servers. Choose a virtual IP address that will be shared between the nfs servers. 4. Configure ucarp vif-up/vif-down scripts on both servers to a)map/unmap rbd volumes, b)mount/unmount rbd volumes, c) start/stop nfs service 5. Add nfs server using the virtual IP you've chosen as a storage to XenServer/ACS This way I am able to perform maintenance tasks on the nfs servers without the need to shutdown the running vms. The switching between master and slave takes about 5 seconds or so and this doesn't seem to impact vm performance. I've done some basic failover tests and the setup is working okay. I would really appreciate your feedback and thoughts on my setup. Does it look like a viable solution for a production env?

When I just create 15-20 vm instances and start them(not run any software on them),I find the disk IO performance of the vm is very low. If a file copy job on a pc needs 10 minutes , the same job on the vm needs 20minutes. I don't know if it is normal,and I want to know the correct configuration of the primary storage,I need your suggests with enough experience.
Re: Problems with Security Groups over CloudStack 4.0.1 with XenServer 6.0.2 and Basic Zone
Ciao Sergio, I suggest using Advanced Zones instead of Basic.
I do not know very well CS4, but in previous versions Advanced zones have a
lot of features.
Ciao
Ignazio
PS (fammi sapere come questa nuova versione)

Hi all, I am trying CloudStack 4.0.1 with XenServer 6.0.2 in a Basic
Zone...
Security Groups does not work.
I follow all the instructions of the manual. CSP is installed and host
network
work in bridge mode.
I have another cluster with KVM that work fine.
On XenServer host, CS don't write any ebtable's rules neither iptables. On
KVM
host ebtable and iptables rule are populated correctly.
Log file management-server.log show these messages when i create a new
instance
in a security group:

Where could I start to troubleshoot SecurityGroups on XenServer? Any
suggestions?
