Virtual Router(s) Restarting on CloudStack-4.2
Greetings ! We have been observing from past couple of days that the Virtual Routers go missing and come back online after some time. There is no trace of it in the management server logs. We have used advanced networking (VLAN) and have multiple isolated guest networks. Has anyone faced a similar kind of issue ? Thanks. -- Md. Iliyas Shirol
how to upload systemvm template to swift secondary storage
Hi, I have a created a new zone in a fresh cloudstack 4.2 , how can I upload the systemvm template to the swift ? I don't see a way using 'cloud-install-sys-tmplt' , should I use the nfs staging instead? Thanks, Jithin
Centos 6.3 + Cloudstack 4.2 Fail to login web UI (404)
Hi all I am installing Cloudstack 4.2 on centos 6.3. Meet following problems: 1) Fail to login web UI HTTP Status 404 - type Status report message description The requested resource () is not available. Apache Tomcat/6.0.24 2) Fail to start Tomcat6 3) run /etc/init.d/cloudstack-agent start and output nothing I can confirm that I have install libvirt and qemu. So, would you please provide me with some advice? -- Best regards, Frank
RE: how to upload systemvm template to swift secondary storage
Hi, It is not required to seed the system VM template with Swift . System VM templates gets downloaded by Management server. Later it gets copied from Swift to Secondary Staging Storage. Please ensure that Secondary Staging Storage (NFS) is configured In your setup.

Tomcat is required for the management server, if it's not running then you won't be able to login to the UI. Did you install tomcat6 packages ? Did you do a 'service cloudstack-management start' to launch the management server ? -Sebastien

Can somebody please suggest me some research areas in cloudstack? Hi Jitendra, it depends what you mean by 'research', but there are a lot of interesting projects to do IMHO: -Integration testing: Develop the Marvin framework and write tests to continuously check the support for CloudStack clients (libcloud, AWS, jclouds etc) this would require learning jenkins, understanding continuous integration pipeline and finding ways to tests these clients automatically. -Investigating Xen GPU passthrough and setting up a demo where Xen hypervisors are tagged specifically for VM that need access to GPUs, run CUDA code on them… -Investigate Mesos framework and develop deployments scripts to automatically deploy Mesos on a CloudStack infrastructure, the end goal being to demo running mixed workloads (MPI, hadoop, spark) on a virtualized infrastructure in cloudstack -Docker integration/use, a few of us have been talking about this and you would be likely to get some help from the community. -Review of configuration management systems (chef, puppet, ansible, saltstack...) develop recipes for deploying cloudstack for all systems (some already exist), from source and from packages. Include management server and hypervisor setup. Ideally had a wrapper to link to the hypervisor and the mgt server together automatically using Marvin. -Investigate PaaS solutions and their integration with CloudStack. Software like cloudify, openshift, cloudfoundry, appscale…some of it is already done but a thorough analysis of pros and cons as well as code writing to finish the integration of some would be great. You can also check out JIRA: https://issues.apache.org/jira/browse/CLOUDSTACK , browse through the long list of 'bugs' and pick what seems interesting to you. This all depends of course on your skills and interest, are you more of a java developer or a sys admin ? Are you interested in integration with third party software or core java development ?

Re: suspend/pause cloudstack VM (kvm hypervisor)
Hi Sebgoa! Thanks for your suggest. I knew how to start/stop VM, but what I wanted is pause a VM without shutdown (or stop in CS term). Using virsh could suspend a VM, but I doubt it is a real suspend which will capture the current VM memory. I guess this feature relies on unsupported virtual machine snapshot for kvm, right?

Re: Research areas in cloudstack
Thanks Sebgoa, Manas Iganzio for your inputs. @Sebgoa: I am into both java and Sys admin. In past, I have worked on IBM Smart Cloud and Open Stack. Have taken more interest in Sys admin. Will think of proceeding with some of the use cases.
