• free up not used space on a qcow2-image-file on kvm/qemu

  - by bmaeser

  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 100GB 2.) 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 with about 40 GB of additional data. the image-file grows up to 50GB. i am ok with that :-) 4.) this is where it gets strange: i delete all of the 40GB data on the image, but the image-size still eats up 50GB. question: how do i free up that 40GB of data and shrink the image to the only needed 10 GB? thanks in advance, berni

• mount qcow2 snapshots

  - by phhe

  I'm running some Xen-servers and started migrating to KVM. Currently my guests are either running on raw-images or LVMs. I found libvirt providing some very nice snapshot features (virsh snapshot-create, ...) so I decided to use qcow2 instead of raw/lvm. And here is my question: libvirt creates the same sort of snapshots on the qcow2 image as if I use qemu-img - is it possible to mount them ? I read something about qemu-nbd and the possibility of mounting qcow but I could not find a word about snapshots.

• How to convert a raw disk image to a copy-on-write image based on another image for use with kvm and

  - by Jean-Paul Calderone

  I have a virtual Windows machine running on kvm. Presently it has a 90GB raw disk image. I would like to clone this VM without having to keep two copies of the 90GB raw disk image around. It seems like a good approach for doing this is to make two new qcow or qcow2 images based on the original. First I converted the raw image to a qcow2 image: qemu-img convert -O qcow2 basewindowsxp.img basewindowsxp.qcow2 Then I tried creating a new image backed by this: qemu-img create -F qcow2 -f qcow2 -b `pwd`/basewindowsxp.qcow2 windowsxp-1.qcow2 Then I used virt-manager to point the original VM at windowsxp-1.qcow2. However, when I try to start up the VM in this new configuration, virt-manager reports an error: Traceback (most recent call last): File "/usr/share/virt-manager/virtManager/engine.py", line 588, in run_domain vm.startup() File "/usr/share/virt-manager/virtManager/domain.py", line 150, in startup self._backend.create() File "/usr/lib/python2.6/dist-packages/libvirt.py", line 300, in create if ret == -1: raise libvirtError ('virDomainCreate() failed', dom=self) libvirtError: internal error unable to start guest: qemu: could not open disk image /var/lib/libvirt/images/windowsxp-1.qcow2 The error suggests that the filename was misspecified or that the filesystem permissions are too restrictive, but neither of these is the case: $ ls -l /var/lib/libvirt/images/windowsxp-1.qcow2 -rwxrwxrwx 1 root root 262144 2010-05-27 08:32 /var/lib/libvirt/images/windowsxp-1.qcow2 Why won't virt-manager start this vm?

• How to use qcow2 disk image in Linux?

  - by sauparna

  I have a large qcow2 formatted disk image, which I use as storage. Often I need to move data to and from this disk image. I mount the disk using the qemu-nbd tool as follows: modprobe nbd max_part=63 qemu-nbd -c /dev/nbd0 /host/disk100G.img mount /dev/nbd0p1 /home/rup/disk But disk access fails every now and then in the midst of some I/O operation with an "Input/output error". At that point I have to manually unmount the disk and re-mount it so that I can run the program again: qemu-nbd -d /dev/nbd0 umount joborkhaki/ What could be the reason for this? Is there a better tool that I can use to maintain a qcow2 disk image?

• ubuntu qcow2 image for local usage

  - by aisbaa

  I'm using kvm and I would like to run ubuntu server on it. My goal is to run db2 database instance for development. Is there ready to use ubuntu qcow2 images online for such purpose? Or should I install it from live cd? I've found this instruction UEC/Images, but at launch I get: $ kvm -fda ${floppy} -drive if=virtio,file=./disk.img -boot a ... Nothing to boot: No such file or directory (http://ipxe.org/...) No more network devices No bootable device. Solution: I havent found pre-installed ubuntu virtual machine image online, so solution is to install it by your self.

• How to distinguish between virtual disk image formats?

  - by Jakub Žitný

  There is huge number of different formats for virtual storage files for desktop and server purposes (vmdk, qcow2, vdi, vdk, etc.). I'm writing a little script for manipulating them and would like the script to be able to distinguish between them. Of course, it can be done via extension, but I want this to be more reliable. I tried commands file or qemu-img, but the results are not quite clear. Any idea improving my methods?

• Ubuntu Server mdadm drbd ocfs2 kvm hangs under heavy file reading

  - by Stefano Annese

  I have deployed four ubuntu 10.04 server. They are coupled two by two in a cluster scenario. on both sides we have software raid1 disks, drbd8 and OCFS2 and on top of it some kvm machines run with qcow2 disks. I followed this: Link corosync is just used for DRBD and OCFS, the kvm machines are run "manually" When it works is fine: good performances, good I/O, but at a given time one of the two cluster started hanging. Then we tried with just one server turned on and it hangs the same. It seems to happen when an heavy READ in one of the virtual machines occurs, that is during rsyn backup. When the fact occurs the virtual machines are not reachable any more and the real server responds with good delay to the ping but no screen and no ssh is available. All we can do is force shutdown (hold the button) and restart and when it turns on again the raid on which relay drbd is resyncing. All the time it hangs we see such fact. After a couple of week of pain on one side this morning also the other cluster hung, but it has different moteherboard, ram, kvm instances. What is similar is reading for rsync scenario and Western Digital RAID Edistion disks on both side. Can anybody give me some input to solve such issue?

• Windows NT from vmware to kvm

  - by Luca Rossi

  I'm trying to convert a couple of old Windows NT virtual servers from vmware to KVM. I tried almost all guidelines and how to I found around the web but with no luck. I have the vmware virtual disk: Dlc1.vmdk partitioned image. I converted the vmdk into qcow2 image with the qemu utility and I tried to use it with kvm: kvm -hda test.qemu -vnc :1 -m 750 but I receive "error loading operating system" I also tried with raw partitions I can mount through losetup and kpartx. but nothing changed I also tried to create an brand new image file with: qemu-img create -f qcow2 test.qcow2 2G I partitioned the new image file and I copied the original partition 1 to the new partition 1 with dd: dd if=/dev/mapper/loop1p1 of=/dev/mapper/loop0p1 bs=128M no luck again I also tried with a single unpartitioned file: qemu-img create -f qcow2 test.qcow2 2G and I copied the partition 1 to the new image file: dd if=/dev/mapper/loop0p1 of=test.img bs=128M but when booting, I receive a black screen and the virtual machine hangs. The bootloader is loaded successfully, because I also tried with a GRUB live iso and I receive the same screens and errors. Note that grub sees the Windows setup and give me the boot choice. I have the suspect the problem is that the vmware machine is probably a scsi guest and in centos 6 (my system) scsi emulation is no longer supported. But in that case, where to change in Windows? I'm not so skilled with MS systems. Thank you for the help Luca Rossi

• KVM and libvirt: How to configure a new disc device to an existing VM?

  - by initall

  I've got an Ubuntu 9.04 server running two VM's. In /etc/libvirt/qemu/machine1.xml two disk devices are defined like this: <devices> <emulator>/usr/bin/kvm</emulator> <disk type='file' device='disk'> <source file='/vserver/machine1/disk0.qcow2'/> <target dev='hda' bus='ide'/> </disk> <disk type='file' device='disk'> <source file='/vserver/machine1/disk1.qcow2'/> <target dev='hdb' bus='ide'/> </disk> I need more storage space in at least one of the devices and thought about adding a third hdc device by simply adding one with same style as above and re-organising my mount structure (The virtual sizes of the current qcow2 files are unfortunately limited.) My problem is that reloading libvirtd and restarting the VM do not result in a new visible device (checked with fdisk). I'm aware of extending an existing qcow2 file (converting to raw format, cat-ing/adding the new one, using smth. like gparted) - but only as a last resort. Hopefully it's something very simple I'm missing?

• Using virt-install to mount multiple cdrom drives/images

  - by Dana the Sane

  I would like to create a windows xp guest from the windows xp upgrade cd I have, along with one of a few full versions I have around. However, when I reach the stage in the installer where I am prompted to insert a full version cd, the installer can't find it, i.e.: Setup could not read the CD you inserted, or the CD is not a valid Windows CD.. Is there a work-around for this?, my Googling didn't uncover anything. I've tried various combinations of mounting .iso files and specifying disks, such as: $sudo virt-install --accelerate --connect qemu:///system -n xpsp1 -r 2048 --disk ./vm/winxp_sp1.iso,device=cdrom --disk ./vm/windows.qcow2,size=12 --vnc --noautoconsole --os-type windows --os-variant winxp --vcpus 2 -c /dev/cdrom --check-cpu If I try to specify multiple cdrom drives, I receive an error: virt-install --accelerate --connect qemu:///system -n xpsp1 -r 2048 --disk ./vm/winxp_sp1.iso,device=cdrom --disk /dev/cdrom,device=cdrom --disk ./vm/windows.qcow2,size=12 --vnc --noautoconsole --os-type windows --os-variant winxp --vcpus 2 --check-cpu Starting install...

• Import virtualBox appliance to KVM

  - by Hugo Bulnes

  Im new using KVM as a virtualization solution. Currently I'm using VirtualBox to manage my virtual machines in my personal computer, but I'm moving my virtualization to a Server, so I set up a Linux server with KVM. And now I'm trying to import a virtualBox vm to KVM. So far I couldn't make it work. I already convert the ova file from VirtualBox to a format more familiar to KVM (qcow2), and I try to create a new virtual machine using virt-install command and setting the new virtual machine hard drive with the .qcow2 file. There is anyone could help me? thank you!

• How to setup VM in KVM? Qcow or LVM etc.

  - by JohnAdams

  Finally, after quite a bit of this vs that, I have chosen to virtualize a couple of my servers with KVM. I did do a test setup as well, but I have a few questions about setting VM's in KVM. Would appreciate pointers. What is the best storage to use - Qcow2 or LVM? I like the fact that I can copy the VM file easily with a Qcow2 but what about LVM, how do I take a backup or make copy on a development server to play with? I know I can clone a LVM, but how do I bring to my development server? How do I setup the guest partitioning? For example, when setting up Ubuntu inside Ubuntu, do I choose LVM for that VM or regular fdisk partitioning? Can I increase the partition size then later, if I need a bigger disk?

• How do I boot Ubuntu Cloud images in vmware?

  - by Graham

  I want to run an Ubuntu cloud image on on VMWare. I've gotten pretty far but want to know how to set the OVF properties in a way that VMWare understands in order to pass parameters to cloud-init. This is what I've done: Install VMWare Player 4.0.4, using the vmware workstation 8.0.2 / player 4.0.2 fix for linux 3.2+ patch to get around the compilation failure for virtual ethernet module. Download precise-server-cloudimg-amd64.ovf, and also the QCOW2 .img file (220MB) Run qemu-img convert -O vmdk precise-server-cloudimg-amd64-disk1.img precise-server-cloudimg-amd64-disk1.vmdk to convert the image from QCOW2 to VMDK Edit the OVF to change the extension and ovf:size on the <File> element and set ovf:format="http://www.vmware.com/interfaces/specifications/vmdk.html#sparse" on the <Disk> element. Edit the OVF to remove all the <Property> elements because vmplayer was complaining about unrecognised elements. Run the OVF in vmplayer. Alternatively, run ovftool to convert to vmx and run the vmx. Unfortunately I can't log in as "ubuntu" at the prompt because the OVF properties haven't been provided to cloud-init. How should I do this?

• How does it hurt to use Linux (Ubuntu) as a guest OS for all my tasks?

  - by sauparna

  I have a machine running Windows, where the disk has two partitions C (50 GB) and D (250GB). I do research in Information Retrieval and need to work with a large corpus (more than 50 GB) and in Linux. So if I want to install Linux on the existing system, keeping the Windows installation intact, will it be fine to run it in a virtual box? (say, QEMU, VMWare, etc.) An alternative is using Wubi. In that case the Linux installation has to be on drive C. Then, if I keep a small Linux installation (say 5GB) on C, and my corpus on D (mounted in Linux), how will it affect the performance of my programs which would be accessing the mounted Windows drive D. Is it feasible to use Linux this way? Which of the above is better if at all they are a way out? Note : Since my post in July 2010, I have been using and have tried several ways of maintaining a disk-image that I can mount in Linux. I had a 100GB qcow2 disk and a 100GB raw disk, both formatted to an EXT3 file system. I was mounting and connecting to the qcow2 disk using qemu-nbd. The problem was that every now and then, the connection to the disk would get lost and the running programs would throw disk I/O errors. The raw disk would mount and work fine as a loop mounted device, but when writing data to it, the mount.ntfs program would hog the CPU and the process would take an enormous amount of time. I was in fact running make on a piece of software located on this raw disk, and after a point of time make was waiting while mount.ntfs would show 100% CPU usage.

• How do I run a stable Windows XP kvm guest on Ubuntu 10.04?

  - by Jean-Paul Calderone

  I have three Windows XP guests running on a recently upgraded 64-bit Ubuntu 10.04 system. Occasionally (on the order of once every few days), one of the guests will become non-responsive and the kvm process on the host which is running that guest will start consuming 100% CPU. It will continue to do so until it is killed. When restarted, it will be fine for a while, and then the issue repeats. The kvm command line used to run all three guests is this: /usr/bin/kvm -S -M pc-0.12 -enable-kvm -m 1024 -smp 1 -name bigdog21vmxp1 \ -uuid ea47ff84-125b-16f7-9a4d-a6d0d8bab46a \ -chardev socket,id=monitor,path=/var/lib/libvirt/qemu/bigdog21vmxp1.monitor,server,nowait \ -monitor chardev:monitor \ -localtime \ -boot c \ -drive file=/var/lib/libvirt/images/windowsxp-1.qcow2,if=ide,index=0,boot=on,format=qcow2 \ -net nic,macaddr=54:52:00:02:06:0e,vlan=0,name=nic.0 \ -net tap,fd=58,vlan=0,name=tap.0 \ -chardev pty,id=serial0 \ -serial chardev:serial0 \ -parallel none \ -usb \ -usbdevice tablet \ -vnc 127.0.0.1:1 \ -k en-us \ -vga cirrus \ -soundhw es1370 Why do the systems misbehave this way sometimes? And what configuration can I change in order to fix it? Or, if the problem is due to a bug in kvm, what is the process for isolating a kvm failure so that the developers have a chance of fixing it?

• How to debug a kernel created using ubuntu-vm-builder?

  - by user265592

  Aim: Trying to perform a code walkthrough of what functions are getting called for sending and receiving packets over the network. I am building a kernel and using gdb for debugging/ tracing purposes. I have build a vm using the following command : time sudo ubuntu-vm-builder qemu precise --arch 'amd64' --mem '1024' --rootsize '4096' --swapsize '1024' --kernel-flavour 'generic' --hostname 'ubuntu' --components 'main' --name 'Bob' --user 'ubuntu' --pass 'ubuntu' --bridge 'br0' --libvirt 'qemu:///system' And I can run the VM successfully in qemu using the following command: qemu-system-x86_64 -smp 1 -drive file=tmpGgEOzK.qcow2 "$@" -net nic -net user -serial stdio -redir tcp:2222::22 Now, I want to debug the kernel using gdb. For this I need an executable with debug symbols(vmlinux), which apparently I don't have, as the vm-builder never asked for any such options and simply created a .qcow2 file. Question 1: Am I taking the correct approach to solve the problem and is there an easier way to do it? Question 2: Is there a way to debug this kernel using GDB? P.S: I don't have hardware support for KVM. Please correct me if I am wrong. Thanks.

• Install KVM based Windows 2008 remotely over SSH on a headless, no graphics Ubuntu 10.04 server?

  - by taazaa

  Hi, I have a Dell server at a remote data center with Ubuntu 10.04 as the host. It is a minimal install with the necessary virtulization packages. There is no X and the machine is headless. I have the win2008 DVD in the machine and want to remotely install it. I tried: virt-install --connect qemu:///system -n vmwin2k8 -r 1024 --disk path=server2k8.qcow2,size=50 --cdrom /dev/sr0 --vnc --noautoconsole --os-type windows --os-variant win2k8 The qcow2 image get created However I don't understand how to connect to see the install via VNC. This is my first time doing it so it may be trivial or may not be possible. Remotely I have a Win 7 machine with Putty and RealVNC viewer. Where is the graphic output of VNC going? Do I have to have VNC server running on the host or some other machine and then connect to it from my VNC client? Please let me know or point me to the right direction. I have been searching the web for several days to figure out how this is suppose to work. Thanks!

• Windows 7 fails to install on KVM with qemu

  - by kief_morris

  I'm trying to install Windows 7 on a virtual machine on my 64 bit Ubuntu Karmic box. I get to the point of selecting my language settings and clicking 'install now', but a short while later I get a blue screen of death. I've tried a few variations, including using the 32 bit (fails very quickly). The virt-install command I've tried includes this: sudo virt-install --connect qemu:///system -n ksm-win7 -r 2048 \ --disk path=/home/kief/VM-Images/ksm-win7.qcow2,size=50 \ -c /var/Software/Windows7/Full/64bit/SW_DVD5_SA_Win_Ent_7_64BIT_English_Full_MLF_X15-70749.ISO \ --vnc --os-type windows --os-variant vista --hvm The limited info I could find suggested that 'vista' should work as the --os-variant, I haven't found any values specific to windows 7. Here's my blue screen: I've found very little by Googling, so I'm guessing this isn't a case of KVM simply not supporting Windows 7. Thanks for any help. Update: I have been able to successfully create a Windows 7 VM using the graphical "Virtual Machine Manager" app, although I don't really understand the cause of the problem with the VM created with virt-install. Comparing the configuration files under /etc/libvirt/qemu provides some clues, although I don't know enough to interpret them properly. The interesting differences in the two VM configurations are: --- win7-virt-install.xml +++ win7-vmm.xml -<domain type='qemu'> +<domain type='kvm'> @@ -21 +21 @@ - <emulator>/usr/bin/qemu-system-x86_64</emulator> + <emulator>/usr/bin/kvm</emulator> @@ -23 +23 @@ - <source file='/home/kief/VM-Images/ksm-win7.qcow2'/> + <source file='/var/lib/libvirt/images/ksm-win7x64.img'/> I'm not sure if this means the working VM is not using qemu at all, or if there is some other difference in the way it's used with kvm. Update2: So I've answered my own question (mostly) below. A KVM VM needs to use KVM's own CPU emulation rather than qemu's in order for me to get Windows 7 installed. I'm not sure whether there is something that can be done to get it working on a qemu-emulation CPU, or whether a newer version will support it. But at least it is possible to get it running on a KVM VM.

  One of my VMs is stuck on "pause" in virsh. If I destroy and restart it, it will go to pause after a bit of time as "running". I can at best enter my username at login if I'm quick but it'll then shutdown. I don't know where to start with this so any help would be great!! I can access the VMs files via guestfish. the kern.log and syslog don't populate new lines. This is the last input I get from kern.log: Dec 13 11:21:08 soft201 kernel: imklog 5.8.6, log source = /proc/kmsg started.
