[libvirt-users] Error starting Virtual Machine Manager: Failed to contact configuration server...
by Allen Qiu 27 Oct '14

Hi all! Do you have any idea about the following error message from virt-manager. I was trying to start it with "sudo virt-manager". Do you think I can fix this by simply restarting libvirtd? Regards, Allen Error starting Virtual Machine Manager: Failed to contact configuration server; some possible causes are that you need to enable TCP/IP networking for ORBit, or you have stale NFS locks due to a system crash. See http://projects.gnome.org/gconf/ for information. (Details - 1: Could not send message to GConf daemon: Did not receive a reply. Possible causes include: the remote application did not send a reply, the message bus security policy blocked the reply, the reply timeout expired, or the network connection was broken.)

[libvirt-users] Using virsh on OSX to control a VMs on a linux machine
by Johannes Kastl 25 Oct '14

25 Oct '14

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi everyone, maybe this is a stupid thing, but Google found no answer. So, for the next one trying this: I have a linux server, that runs a couple of VMs, and on which libvirt and virsh work like a charm. From time to time I'm on a Mac OSX machine, where I can install libvirt from macports very comfortably. But this far I have not gotten it to work with anything apart from the virtualbox that is installed on osx. I always get a hangup error, that is not listed on http://wiki.libvirt.org/page/Failed_to_connect_to_the_hypervisor: > error: failed to connect to the hypervisor error: internal error: > received hangup / error event on socket So I had to enter the path to the socket (on the linux machine), as the OSX libvirt thinks it is in /opt/local/..., where the whole macports stuff is. On linux it's in /var/run/libvirt/. So, the following works: > virsh -c > qemu+ssh://example.org/system?socket=/var/run/libvirt/libvirt-sock > list --all Regards, Johannes - -- `Even if I could, I wouldn't. Scars can come in useful.

[libvirt-users] libvirt guests graceful shutdown upon hosts powerdown/reboot
by lejeczek 25 Oct '14

25 Oct '14

hi everybody by an assumption I expected VM guests to be shut down/off gracefully when the host is being powered down or rebooted, but this does not seem to be the case so I wonder.. Am I missing some libvirt components/packages ? Or my assumption is incorrect and guests have to be shutdown manually? it's all SL 7 and guest are M$ regards P.

P { margin-bottom: 0.21cm; }Hi! I'm using libvirt withVirtual Box. I have installed libvirt 0.10.2 and Virtual Box 4.1. I want to use "virsh define"to define my Virtual Box virtual machine. My question is: In my domain.xml, how can Ispecify that my hard disk is of type immutable/ multi attach etc. Can I use som kind oftag or attribute, something like this: <disk type='file'device='disk'> <sourcefile='/path/to/my/file.vdi'/> <target dev='hda'bus='ide'/> <type>immutable</type> </disk> In the domain.xml is it possible to specifythe path to my folder where I have my snapshot.vdi file? Thanks! LL

Hi, I’m an openstack developer trying to use Assignment from a pool of SRIOV VFs in a libvirt <network> definition from this link http://wiki.libvirt.org/page/Networking My question is is it possible for nova (the openstack compute) to know which VF out of the pool will be allocated to a VM before it invokes libvirt to launch it? Thanks In advance, Robert

[libvirt-users] Public IP addresses are not logged in VMs
by Roland Giesler 24 Oct '14

24 Oct '14

Anyone that can help me solve this one? I have around 4 VM's on a server and the network is bridged and a /28 public IP range assigned to it . When a client connects to one of the VM's, they all always log the address of the host server, never the client ip address. How can I fix this? Things I have investigated: 1. Switch to routed network. That would not help, since I would firstly need another public IP subnet to route to (the virtual machines). 2. Could have something to do with the libvirt firewall rules, but they are default, I didn't touch them I have read many posts in forums and websites, but none make any mention of this behaviour. Help would really be great!

[libvirt-users] Libvirt with containers
by Anjali Kulkarni 21 Oct '14

21 Oct '14

Hi, I am trying to define a container using libvirt, and I need to allow access of the device /dev/uio0 on the host on the container as well. That is, I have the following line in the container config file: lxc.mount.entry = /dev/uio0 dev/uio0 none bind,create=file lxc.cgroup.devices.allow = c 249:1 rwm And I want to add it in the libvirt XML file for the container. I tried something like: <filesystem accessmode="passthrough" type="mount"> <source file="/dev/uio0" /> <target dir="/dev/uio0" /> </filesystem> But it gave me error: root# virsh -c lxc:/// define lxc_v.xml error: Failed to define domain from lxc_v.xml error: missing source information for device /dev/uio0 Can someone pls help, how I can add the /dev/uio0 to the xml file? Thanks Anjali

[libvirt-users] HostDevev SCSI Devices
by Fl＠sh 21 Oct '14

21 Oct '14

http://libvirt.org/formatdomain.html#elementsHostDevSubsys At this description used "drive"-typed address for SCSI. But when i get xml-description of scsi-devices by <code> unsigned int flags = VIR_CONNECT_LIST_NODE_DEVICES_CAP_SCSI_HOST ; int ret = virConnectListAllNodeDevices (currWorkConnect, &nodeDevices, flags); then get by virNodeDeviceGetXMLDesc(nodeDevices[i], 0)); </code> i have same: <device> <name>scsi_host2</name> <path>/sys/devices/pci0000:00/0000:00:1f.2/ata3/host2</path> <parent>pci_0000_00_1f_2</parent> <capability type='scsi_host'> <host>2</host> <unique_id>3</unique_id> </capability> </device> . I understand that this device description contains a "pci"-typed addresses. Then where to get the "scsi"-typed address? -- Fl@sh
