I was trying to install openstackin Ubuntu12.04 server. I find that Nova-compute is not getting started and the error is the below. I followed some of the suggestions in various forums, but nothing worked. It’s a 64 bit kernel, Virtualization also enabled.

kvm-virtualization qemu disk-images qcow2
we are using kvm/qemu with qcow2-images for our virtual machines.qcow2 has this nice feature where the image file only allocates the actually needed space by the virtual-machine. but how do i shrink back the image file, if the virtual machine’s allocated space gets smaller?example:1.) i create a new image with qcow2 format, size 100GB2.) i use this image to install ubuntu. installation needs about 10 gb, the image-file grows up to about 10GB. nothing unexpected so far.3.) i fill up the image wit

timeout qemu libvirt kvm-virtualization
There’s a known issue with starting virtual machines with large hard drive images. Apparently, the time-out is 3 seconds, but in reality, it can take up to 15 seconds for a machine to start. I’ve read several bug reports, and people confirming it’s a time-out problem, but I have yet to see a solution.Is there an option I can pass, like:virsh start MyMachine –ignore-timeoutOr a config file that needs changed?Thanks!

python c gdb qemu
I’m working on a class project (don’t worry, this question is not homework) and recently moved from department machines to my own machine. The project is to build a simple operating system. To make the task easier, we are provided with the ability to “attach” gdb to QEMU in which our program runs. Running this program without attaching gdb on my computer works fine, however it is when I start trying to use gdb that it does not run. The main thing to note (I think) is that it runs fine on the dep

I’ve posted a similar question with a similar problem but on windows XP. So i installed ubuntu 11 and this> sun-jdk 6, sun-jre 6, eclipse galileo, adt plugin and the android sdk. Not even the 1.5 android target device works. Just loads forever, reaching the flashing android word screen and it goes on and on. I let it load for a hour and nothing changes. What’s the checklist to make this run? I am very dissapointed with this situation.Specs> Athlon 64×2 3600+, ram = 1.5 GbI made the default 1.5 t

I’m having a problem with libvirt. On a system restart all virtual machines (VMs) are started without a problem and keep running. Then at some point in time a set of machines shuts down according to their log. When I try to restart the machine, I’m getting an error that the memory allocation failed, although more than enough memory is free.server ~ # freetotal used free shared buffers cached Mem: 16176648 16025476 151172 0 285432 950300 -/+ buff

backup virtualization kvm-virtualization qemu
Assume a KVM/QEMU VM, which uses qcow/qcow2 as the image format for virtual disks. Backup is (to be) done on the VM host.As far as my current understanding goes is that while we can create backups from the vm right out of the box using snapshots (with LVM, for example), these backups are merely crash-consistent, which is really not appropiate IMHO. Also, upon closer inspection, a lot of the tools and scripts currently floating around are doing exactly that – so either the authors were lazy or mi

I was trying to create a raw image with this command:qemu-img create -f raw -o size=200G,preallocation=metadata file.imgbut seem that it raw images doesn’t support preallocation. if so why there is raw + preallocation in this chart?# qemu-img create -f raw -o size=200G,preallocation=full file.img Unknown option ‘preallocation’ Invalid options for file format ‘raw’.

I’ve been coming up to speed on the Haiku operating system, an Open Source clone of BeOS 5 Pro.I’m using an Apple MacBook Pro as my development machine. Apple’s BootCamp BIOS does not support more than four partitions on the internal hard drive. While I can set up extended and logical partitions, doing so will prevent any of the installed operating systems from booting. To run Haiku directly on the iron, I boot it off a USB stick. Using external storage is also helpful because I am perpetual

debian-lenny qemu kvm-virtualization powerpc
I want to install kvm on debian(lenny). I have learnt that packages kvm and qemu-kvm are not available for powerpc architecture. I have found two packages(kvm-source & qemu) and installed it. Now, how do I install kvm. Do I need to install libvirt-kvm as well.[Edit1]: Approach1: I downloaded qemu-kvm source code (http://sourceforge.net/projects/kvm/files/qemu-kvm/0.13.0/qemu-kvm-0.13.0.tar.gz/download) , configured #./configure –target-list=”ppc-softmmu” #make But I am getting this error

I have installed KVM on my Ubuntu system. Using vmbuilder, I setup a linux VM. When I tried to access the console using virsh console vm command, I was getting an error. I tried to follow the solution but, I cannot seem to be able to make permanent changes whatsoever to the configuration file. I tried both manually editing the xml config file as well as using the virsh edit command. But after I edit the file and close it, if I reopen the config file using virsh edit again, I get back the origina

c qemu
in qemu source code, I have the following macro named offsetof. Can anybody tell me what it does? #define offsetof(TYPE, MEMBER) ((size_t) &((TYPE *) 0)->MEMBER)It’s used in this manner :offsetof(CPUState, icount_decr.u32)where CPUState is a struct.I think it gives the offset of the member inside a struct, but I’m not sure.EDIT:Yeah, I found out what was happening. The definition of CPUState had a macro inside, which I missed, which included the variable icount_decr.

linux networking bridge qemu
I’m trying to get an ARM QEMU system out on my LAN. I tried running QEMU directly from Windows (Windows 7 x64), with success except I could not get a TAP adapter to bridge to my wireless connection. Specifically, Windows refused to bridge any of my network adapters.So, I tried using QEMU within a Ubuntu virtual machine (which, surprisingly, turns out to be quite a bit faster, which is why I’d like to stick with it). The Ubuntu VM is bridged to my wireless connection, and works fine. I’ve setup a

I’m having an issue with performing virtualisation via libvirt/qemu-kvm, in which my set up for bridged networking doesn’t appear to be working correctly. I’ve followed every tutorial I can find and spent hours and hours going through forums, but currently to no avail.Both the host and guest are using Centos6.

Apart from one Virtual Host still running Xen/RHEL5, all our virtual capability is hosted on KVM hosts with LVM storage devices. I’ve stupidly attempted an Ubuntu full release upgrade on a guest running on the Xen machine, only to have it install a non-Xen kernel and refuse to boot (rookie error there).Getting to the actual issue, the machine in question uses a single file based storage device. It’s been a while since I’ve had to open one of these, but the process shouldn’t be much different f
