[libvirt-users] Migrate VM's to different storage pool?
by Jamie Fargen 22 Feb '13

22 Feb '13

I am searching for directions for using live block migration to copy running vm's to a different storage pool. Example: VM1 running on Host1, the image(s) for VM1 are stored in /var/lib/libvirt/images. I'd like to copy the disk image(s) that VM1 is using to /nfs/images. Without stopping/pausing/powering down the VM. Do you have any examples or documentation of how to accomplish this process? Regards, Jamie Ian Fargen

by Parakkal, Navin S 17 Feb '13

Hi, I'm able to get the CPU utilization metrics from libvirt for the guests (VM's) remotely . Is it possible to get the Host Cpu stat's through libvirt ? I didn't find any information regarding the host cpu cycles and memory utilization to collect them remotely. Libvirt is installed on all the hosts. Regards, Navin

[libvirt-users] Out of Memory Error
by varun bhatnagar 14 Feb '13

14 Feb '13

Hi, I am trying to attach a usb device to my virtualbox node using libvirt. My node is already running, I stop my node and then I am trying to add this usb device. I have a separate xml file defined for usb. It looks like this: *<device> <hostdev mode='subsystem' type='usb'> <source> <vendor id='0x4321'/> <product id='0xfeeb'/> </source> </hostdev> </device> * * * I am trying to attach it using code: *conn = libvirt.open("vbox:///session") if conn ==None: print 'Failed to open connection to the hypervisor' sys.exit(1) print 'connected to vbox hypervisor driver' domainInstance = conn.lookupByName('SampleNode') filed = open('/root/testFolder/usbSharedFolder.xml', 'r') config_str = filed.read() libvirt.virDomain.attachDevice(domainInstance, config_str)* When it is executed I am getting an error message saying: *libvir: VirtualBox Driver error : out of memory * * * Even with virsh it is giving the same error. I am using the below command: *attach-device SampleNode /root/testFolder/usbSharedFolder.xml* Can anyone tell me what is going wrong. It is really very important. Please do reply. Thanks in advance.

Hi all, it's possible to change/add the QoS settings for a running domain? I edited the domain definition with virsh but it seems to have no effect until I shut down the domain. libvirt version 0.9.13 kvm-qemu version 1.2.0 Best, Davide.

[libvirt-users] [Q] how to manage Infiniband disk(SRP) volume wit libvirt.
by Hiroyuki Sato 13 Feb '13

13 Feb '13

Dear members. I'm looking for best practice for administration Infiniband SRP volume with libvirt (virsh) How to manage these volumes? * SRP Disk is /dev/disk/by-id/scsi-2766f6c3030303037 or /dev/sdi Now I edited guest domain file with ``virsh edit XXXX'' command and append the following lines. <disk type='block' device='disk'> <driver name='qemu' type='raw'/> <source dev='/dev/disk/by-id/scsi-2766f6c3030303037'/> <target dev='vdc' bus='virtio'/> <address type='pci' domain='0x0000' bus='0x00' slot='0x06' function='0x0'/> </disk> It seems work fine, however I feed it is a little bit slow. Can I attach this volume another(good performance) way? ie. attach as scsi disk. Thank you for your advice. Sincerely. -- Hiroyuki Sato

[libvirt-users] OSX rpcgen problem

Trying to build the virtualbox-4.2 branch from git://pipo.sk/pipo/libvirt.git under OSX 10.7, I get the following build error: ...

If so, I guess I'll have to wait for a tarball before I can try this out. Unfortunately I upgraded to virtualbox 4.2 and this means I've lost the ability to control it using virsh :-( Regards, Brian.
