I'm trying to build libvirt-sandbox under ubuntu 12.10 sudo apt-get install git build-essential lxc libvirt-bin libvirt-glib-1.0 libglib2.0-0 libglib2.0-dev gtk-doc-tools libxml2-dev libselinux-dev git clone git://libvirt.org/libvirt-sandbox.git cd libvirt-sandbox sudo ./autobuild The error I'm getting: make[2]: Entering directory `/home/user/libvirt-sandbox/build/bin' CC virt_sandbox-virt-sandbox.o CCLD virt-sandbox CC virt_sandbox_service_util-virt-sandbox-service-util.o make[2]: *** No rule to make target `container.c', needed by `virt_sandbox_service_util-container.o'. Stop. Am I doing something wrong? Thanks

[libvirt-users] http problem with (a particular url) and default (nat) networking
by John McFarlane 29 Jan '13

29 Jan '13

At work I have a script that provisions a vm for use by employees. One step in this process is to fetch hadoop, which we happen to get from cloudera. I noticed the script always failed when I used libvirt's default networking (nat) but worked fine when I used user mode networking. My instinct is that this is related to (potentially uncommon) network traffic from the server in question, and the iptables rules added by libvirt. Repro steps: 1. Create a vm (I tested with linux and freebsd guests) using default libvirt networking settings (<interface type='network'>). 2. wget, curl, fetch: http://archive.cloudera.com/one-click-install/lucid/cdh3-repository_1.0_all… Observe it will "hang". If you use strace you'll see it block on the select call. My particular host is using a virbr0 network bridge, with the following iptables rules: $ iptables -S -v -Z -P INPUT ACCEPT -c 404828 91071544 -P FORWARD ACCEPT -c 0 0 -P OUTPUT ACCEPT -c 402905 45139291 -A INPUT -i virbr0 -p udp -m udp --dport 53 -c 26 1703 -j ACCEPT -A INPUT -i virbr0 -p tcp -m tcp --dport 53 -c 0 0 -j ACCEPT -A INPUT -i virbr0 -p udp -m udp --dport 67 -c 70 22960 -j ACCEPT -A INPUT -i virbr0 -p tcp -m tcp --dport 67 -c 0 0 -j ACCEPT -A FORWARD -d 192.168.122.0/24 -o virbr0 -m state --state RELATED,ESTABLISHED -c 1191 1495856 -j ACCEPT -A FORWARD -s 192.168.122.0/24 -i virbr0 -c 853 64266 -j ACCEPT -A FORWARD -i virbr0 -o virbr0 -c 6 1968 -j ACCEPT -A FORWARD -o virbr0 -c 0 0 -j REJECT --reject-with icmp-port-unreachable -A FORWARD -i virbr0 -c 0 0 -j REJECT --reject-with icmp-port-unreachable Zeroing chain `INPUT' Zeroing chain `FORWARD' Zeroing chain `OUTPUT' I'm not sure how best to diagnose this problem. Any ideas or tips? Thanks! John M.

[libvirt-users] not able to stop vmware player node through libvirt API
by varun bhatnagar 29 Jan '13

Hi, I have started one node through libvirt API using its start method. I am trying to stop that node using the *destroy *method provided by the API but I am not able to do so. Instead, I am getting one message saying: *libvir: error: internal error Child process (vmrun -T player stop /root/test_folder/myImage.vmx soft) unexpected exit status 255* Can anybody tell me why I am not able to stop the node. Thanks in advance. :)

[libvirt-users] limit memory and CPU when using libvirt-sandbox
by pablo platt 28 Jan '13

28 Jan '13

I'm considering using virt-sandbox with lxc to sandbox and execute untrusted code like python scripts and compiled C code. Is it possible to limit CPU and Memory like is possible with lxc-execute and a config file? What are the defaults security settings? Is it completely isolated by default? What's the difference between lxc-execute and libvirt-sandbox? How can I use it in ubuntu? Thanks

Hi, I am having issue while doing *ssh* to a virtual node through libvirt. The nodes's ip address is 192.168.82.1. When I am giving the command it is giving the following error message: *virsh# connect vbox+ssh://192.168.82.1/session* *Password:* *error: Failed to connect to the hypervisor* *error: End of ifle while reading data: sh: nc: command not found: Input/output error.* Can anyone tell me why am I facing this problem and how to resolve it. Thanks in advance.

by 韩诚 25 Jan '13

Hi, Paolo, All, I read "virtio-scsi support proposal v2"(http://permalink.gmane.org/gmane.comp.emulators.libvirt/50428) Try to add a virtio-scsi with scsi-generic like this: <hostdev type='scsi'> <source> <adapter name='scsi_host0'/> <address type='scsi' bus='0' target='0' unit='0'/> </source> <target> <address type='scsi' controller='0' bus='0' target='0' unit='2'/> </target> </hostdev> But It turn out to be wrong, showing: error: Failed to define domain from rhel63ga error: XML error: unknown host device source address type 'scsi_host' I'd like to know how shall to add a virtio-scsi disk with scsi-generic option. Thanks~ -- Best regards, Cheng

Re: [libvirt-users] snapshot troubles
by Christian Schmidt 23 Jan '13

Hi Juergen, if you are using kvm/qemu with libvirt you can try to delete the snapshot with the qemu monitor commands. The general syntax is virsh qemu-monitor-command --hmp <domain> '<command> [...]' So you can try virsh qemu-monitor-command --hmp DOMINO1-prealloc 'info snapshots' and thne delete it with the provided snapshot ID virsh qemu-monitor-command --hmp DOMINO1-prealloc 'delvm <ID>' This will delete the snapshot from your diskimage.

[libvirt-users] snapshot troubles
by jurgen.depicker＠let.be 23 Jan '13

23 Jan '13

Dear all, I created some snapshots, a long time ago, using the xml description option, so the snapshots have a name with a space in it... Really a bad choice apparently, since it seems impossible to delete them now: I cannot find how to enter the snapshot name properly due to the space. Quotes don't seem to help; escaping the space doesn't help either. Anybody knows how to solve this? eg: snapshot-delete DOMINO1-prealloc --snapshotname 'W2K3-virgin install' error: Domain snapshot not found: no snapshot with matching name ''W2K3-virgin' (-> notive also the extra ' added ) root@VLET3:~# time virsh snapshot-delete DOMINO1-prealloc "W2K3-virgin\ install" error: unexpected data 'install' Thanks, Juergen

[libvirt-users] Fwd: problem with libvirt
by rakshith h p 23 Jan '13

23 Jan '13

HI, i'm rakshith from bangalore. I'm using libvirt in one of my work. I have a problem in using it.So i would request your guidance. I have a controller which uses libvirt to establish the connection to the managed nodes. After the connection is successful, if the network goes down, the control will indefinitely wait inside the libvirt mod functions. It will come out only after the network is back and required data is obtained. In this case i need to add time out and get the control back once the data is not available and throw an exception. Can u please tell if there is any way i can do it.Thanks in advance -- Thanks and regards Rakshith H P Mobile - +919844303929
