[libvirt-users] managedsave results in unexpected shutdown from inside Windows
by Nicolas Sebrecht 28 Jun '13

28 Jun '13

Hi, I'm facing a strange behaviour of windows 2008 guests. After a virsh managedsave and start, the windows guest open a "unexpected shutdown" window. The window looks like this one (randomly taken from the web): http://toastytech.com/guis/srv2k3login2.jpg This happens in all virtualized windows in a hypervisor. Has anyone else experienced such issue? Thanks, -- Nicolas Sebrecht

[libvirt-users] qemu-img convert to "sparse" LV
by Edoardo Comar 28 Jun '13

28 Jun '13

Apologies as this is is not a specific libvirt question. Is qemu-img convert compatible with thin-provisioned LVs as targets ? I wanted to convert a file-based image to a LV image where the file-based image has a capacity much larger than the actual data it contains, so it has a small footprint on disk (either a qcow2 or a raw, but sparse, image). If I use qemu-img convert -O raw ... with a target LV sized to the full capacity of the file-image, all is fine. But if I try use an LV whose virtual size equals the capacity, but its size is smaller (although more than enough for the data) the LV is invariably corrupt. If I try use a thin-provisioned LV pool, and a LV backed by that pool, the LV resulting from qemu-img convert is not corrupt but it uses as much space as the file-image capacity it came from. This on both RHEL64 and Fedora18. -------------------------------------------------- regards, Edoardo Comar WebSphere Application Service Platform for Networks (ASPN) ecomar(a)uk.ibm.com +44 (0)1962 81 5576 IBM UK Ltd, Hursley Park, SO21 2JN Unless stated otherwise above: IBM United Kingdom Limited - Registered in England and Wales with number 741598.

[libvirt-users] error : Failed to find user record for uid '32722'
by Tony Cebzanov 28 Jun '13

28 Jun '13

I'm trying to use the libvirt Python API to manage VirtualBox VMs on Mac OS X 10.8.3. I'm running libvirt 1.0.6 via Homebrew. However, the following trivial Python script: import libvirt conn = libvirt.open('vbox:///session') gives me the following error: libvirt: error : Failed to find user record for uid '32722': Success Traceback (most recent call last): File "ch3vm.py", line 3, in <module> conn = libvirt.open('vbox:///session') File "/usr/local/lib/python2.7/site-packages/libvirt.py", line 236, in open if ret is None:raise libvirtError('virConnectOpen() failed') libvirt.libvirtError: Failed to find user record for uid '32722': Success I have no idea where that uid 32722 is coming from -- it's not the uid of my user account, any of my VirtualBox files, or anything else that I'm aware of. Anyone have any idea what's going on here?

[libvirt-users] virsh can create vHBA, but returen error msg "Node device not found"
by Dennis Chen 28 Jun '13

28 Jun '13

Hi, I am using the libvirt 1.0.6 with the patch applied: http://libvirt.org/git/?p=libvirt.git;a=commitdiff;h=371c155 The problem I encountered is, with virsh comand 'nodedev-create /home/kvm/vHBA.xml', the vHBA can be generated as expected on the host, but error msg will show in the virsh shell: libvirt: Node Device Driver error : Node device not found I try to find the reason with gdb, and found that the 'nodedev-create' command will call virNetClientIOEventLoop() function of the remote driver, in this function, code will wait on: repoll: ret = poll(fds, ARRAY_CARDINALITY(fds), timeout); after about 50s, poll() returns, but the replied msg->header.status=VIR_NET_ERROR. I am not familiar with the rpc call in the remote driver, does anybody here can give some clues? BRs, Dennis

[libvirt-users] Define storage pool on NFS, mounted from fstab
by Николай /Thug/ 27 Jun '13

27 Jun '13

Good day. We've got a question, as there's a need to mount NFS over RDMA. How we should define a pool on an already mounted NFS folder? The pool must be "shared" for all KVM nodes for live migration purposes. Thanks in advance.

[libvirt-users] snapshot-create-as for a single disk not all disks
by cmcc.dylan 27 Jun '13

27 Jun '13

Hi everyone! Is there any way to create snaphot for a single disk of a virtual machine. As I konw, "virsh snapshot-create-as domain_name snapshot_name --disk-only" traverses all block devices to create snapshot. However I don't want to create snapshot except for root partition. The version of qemu and libvirt I used is as follows: qemu-1.4.2 and libvrit-0.10.2 I meet an error when I delete the snapshot which is created by "snapshot-create-as" command. whether or not qemu(1.4.2) and libvirt(0.10.2) don't support the function currently. Look forward to your help!
