Questions related to Server Virtualization
What is the accuracy of these images regarding their geo-referencing and how accurate are they for their use of known sites with control points for geo-referencing?
Is it possible to conduct a real experiment to make voice call over IP to test NFV resiliency using test-bed?
If Yes, is there any open source VoIP servers and client to use them as VNFs in the environment?
How to implement the VoIP server on vIMS, if possible?
Considering the following requirements or your advice:
Scenario: testing real voice call on NFV.
Method: prototyping or test bed.
Metrics: delay, voice quality, packet loss
OS: Linux (what is preferred distribution?)
while creating instance in openstack i am getting static IP problem. how avoid this?
When I print the database script file from the xampp it gives me the relationship between the table in a machine language? But I would like want to see the manually primary key and foreign key constraint.
Dear Researchers;
In energy aware VM scheduling, we tend to determine current server temperature or load before we activate a VM on that server. Is there a way we can predetermine the temperature change when the incoming VM is activated?
Thank you.
I have installed a Hadoop 2.6.0 Cluster using one NameNode (NN) and 3 DataNodes (DN). Two DNs are on two physical machine running Ubuntu while 3rd DN is virtual node running Ubuntu on window server. Two physical DNs have 2 GB RAM and Intel Xenon 2.0 GHz Processor x 4 (i.e. 4 cores). While 3rd DN is assigned with 4 GB RAM and 1 processor x 4 (i.e. 4 cores) and it is running on window server which have 32 GB RAM and 2 Intel Xenon 2.30 GHz processors x 6 (i.e 12 cores).
Mappers running on Physical DNs are faster than Mappers running on Virtual DN. Why ?
Is this possible with Libvirt or there exists some other means?
NOTE: This can be done within the Guests themselves but the interest here is to get the stat externally at the host. I have seen an approach for KVM but haven't seen anything for XEN servers.
I have little knowledge about the server consolidation tools but I am not very skilled so I need to know the open source tools available.
The goal is to be able to manage multiple services on the same host in a Xen environment. Xentop provides CPU utilization for each VM running on the host and we have also been able to do thesame in realtime using the Libvirt framework.
However, since MEMORY is not shared but pre-allocated (at VM creation time) and scaled with ballooning by the hypervisor, the host has no knowledge of how each domain is using their shares, whether for caching, buffering or whatever. So using xentop and virsh memory options will always produce the fixed memory shares.
I have similar problem with getting the DISK (guests are granted direct access to disk resources) and NETWORK utilizations for each domain externally from the VMs.
Please kindly drop any experience or suggestions you may have here.
NB: One alternative is to find other means to derive the MEMORY utilization of each domain from maybe their CPU utilization or some other counters on the host directly. If you have links to papers or you have an idea and methods to achieve this please kindly state here.
To migrate a Virtual Machine(VM) from mobile device to a nearest Cloudlet, which linux query is needed to write for triggering the resume state of the server virtual machine? Where to write this Script ? Is it possible that Use a windows 7 or any Microsoft Windows as host OS and then migrate the VM to test ?
Can we allocate resources in different way of vmallocation?
In live migration, Can be measure load balance capacity of all Virtual Machine with the respect of VM distance? Which method is effective and what will be do for future efficiency enhancement in live migration.
Node consolidation, data centers, grid computing are used to save power in access network. Please tell me how power is reduced.
In IaaS cloud computing, VM migration is achieved in order to load balancing, fault tolerance, maintenance etc. with out the consent of end user or cloud consumer. In this process of VM migration what components of VM will be modified? Will OS running on VM will be changed or remain same? Will Core components of VM such as BIOS, Boot Loader, OS be changed during migration of VM?
Thanks in anticipation.
To allocate the correct VM for a user's job/task, how do we know the requirements of incoming jobs to the server for best selection of VMs. Is there any way to know the what will be needed to get users job/task to be executed efficiently?
Though Virtual Machine is sandboxed, what are the potential security issues ?
We are hosting our institutional application based services on virtual server but as I think cloud servers are the best rather than using virtual servers. Can anyone help me in clearing these issues?
I am looking for a free solution for slaves-master-clients type distributed computing.
More precisely, I have 30 PCs (identical configurations) that I’d like to put into a grid of slaves that would be coordinated by a single master computer in order for the master computer to run a virtual machine with its computational power being drawn from parallel processing across the provided slave grid.
On this virtual machine, I’d run an operating system (Windows or a Linux distribution) and a VR server which is very demanding and it should be able to handle many connections (this is why I require a lot of computational power).
I'm trying to accomplish this with 30 PC’s (they are somewhat powerful) and a fast gigabit local network, instead of buying a dedicated server.
Can anyone suggest an easy to implement solution that I could try?
I am new in this field and am trying to explore the field but after going through many papers related to these topics I couldn't find what the key parameters in VMs are. Most of them have considered cpu, memory and time but these are not sufficient , are they?
Suppose any client wants to execute some programme on cloud and she/he asks for a particular environment(in general). what are the things she/he might want from a vendor?
