I have a software that is pretty complex in the sense that it uses a lot of interacting processes, os daemons, services, etc. So I think the most sensible way of distributing it would be as a virtual machine image, otherwise the installation in an arbitrary machine would be too complex. What are the pros and cons of such a model? What...
Currently we have assorted development build/test boxes. The target Application is mainly written in Python/gcc, uses postgres and has 2 identical USB devices attached. The principal build OSes are RHEL, FreeBSD & XP on i686. The App needs to be regularly built and tested on a couple of releases of each OS. (Maybe the next step would b...
Hi, Just a quick query on anyone whos worked with XenServer, I want to setup a NAS at home but with virtualization (I've looked into VMWare Server and KVM, I quite like KVM!) but I was told about XenServer 5.5. I have comomodity hardware (ASUS board, dual core 2.66Ghz CPU with 8Gb RAM), I need to setup a fileserver to house about 2-3Tb...
Does anyone know if there is a full XenServer API implementation in ruby floating around out there? I found this: http://github.com/rubiojr/pangea/tree/master but its read only and not fully built out. ...
I have Fedora 11 and trying to get Xen working (which I think it is already) but the Virtual Machine Manager cannot find the hypervisor. When starting Virtual Machine Manager, I receive the following error Error determining default hypervisor. Could not populate a default connection. Make sure the appropriate virtualization packages ...
After a Xen guest domain hang, I took a dump using xm core-dump . Following the sparse documentation I found, I tried using the crash utility to analyze the dump. Unfortunately, the kernel image (Debian lenny) is stripped, so I am forced to make use of the map file. However, crash /boot/System.map-2.6.26-2-xen-amd64 vmlinux-2...
I want to build a service to provide console access (eg. xm console domain) via a web browser to Xen virtual machines. Does such a program already exist? If not, where should I start? Slicehost offers this service. I'm just wondering how to go about cloning it or using whatever software that they did. ...
I'm using the VNCsharp .NET control to attach to remote XenServer sessions using their VNC protocol. This control has been working great except for one when the VM's resolution is increased. For example from 800x600 to 1024x768. The console viewer in XenCenter handles this situation fine! In that case, it appears as if the XenServer ...
Is there a way to export a openvz VM from proxmox to xen? Tkz ...
I am trying to understand this inline assembly code which comes from _hypercall0 here. asm volatile ("call hypercall_page+%c[offset]" \ : "=r" (__res) \ : [offset] "i" (__HYPERVISOR_##name * sizeof(hypercall_page[0])) \ : "memory", "edi", "esi", "edx", "ecx", "ebx", "eax") I am having trouble finding informatio...
What are the tools available to place on the level on top of VMWare or Xen (or other VM managers) that would monitor the VMs? I know there are a few solutions like Netuitive, CA Infrastructure Manager / eHealth, Nimsoft - what are the areas of application and how popular are they? CA has root-cause analysis of potential problems with ...
Hi community, I have the following problem with a Citrix XenServer 5.5. I had to physically move the host, so I shut down all machines via console: xe vm-shutdown force=true vm=my-machine-uuis-s After that I shut down the machine itself by issuing: halt After the reboot today the local storage repository is unplugged. I was tryin...
I'm reading an article about Xen, a virtual machine monitor. They say that an operating system requires some modification in order to be able to act as a guest OS on top of Xen. Now, for an OS like Linux, I can understand what a "modification" might mean but in the case of an OS like say, Windows XP, what does it mean? I mean, XP is clos...
Looking for ideas on how to detect when our Windows application is running in one of the following VM environments. Some starter ideas for detection are in parentheses. There may be (much) better detection techniques - the starter ideas I've come up with are based on my Google research. VMWare (looking for the presence of optional VMwa...
Are there tools for migrating from one virtual machine type to another? E.g let's say I have some Xen virtual machine and like to make it run under KVM. I know that qeumu has tools which can be used to "migrate" such machines, but how about: Xen -> Kvm Kvm -> Xen Xen -> VMware (server?) ...
Hi All, I am trying to implement a peer to peer communication .. I use sockets for communication between them. I want to know if there are any ways i can use the same sort of communication when the two peers are behind two private Networks (They dont know each others public ip address.) I can think of a shared buffer in a well known l...
I want to turn daily my XenServer off on 21pm and turn it on on 6am. How do I do that? ...
It's fairly popular for companies offering a quick way to test their product to give you a vmware player image. I don't run VMWare though, I run Xen exclusively. Most of these images (and the one I'm interested right this moment particularly) are linux images. Is there a way to use this image with Xen? Obviously, I could setup player...
Hi, I want to know if there is any open source testing tool for cloud computing. We have built a cloud framework with Xen, Eucalyptus, Hadoop, HBase as different layers. I am not looking at testing each of these tools separately, but i want to test them from the perspective of fitting into a cloud environment (for example scalability of...
Hello, For the first time, I am asking a little bit of help over here as I am more of a ServerFault person. I am doing some scripting in Python and I've been loving the language so far yet I have this little problem which is keeping my script from working. Here is the code line in question : subprocess.call('xen-create-image --hostna...
