Hi Alex, when I got this error, it was a vnc listener problem. Is there other actives vms on this server? try to change the port number to see if the problem was solved. <graphics type='vnc' listen='0.0.0.0' port='5909'/> Good Luck.

[libvirt-users] no connection driver available for No connection for URI xen:///
by Su Zhang 16 Mar '12

16 Mar '12

Hi all, I am trying to use virt-install to install domU image. However, I encountered the following issue. It seems that a connection driver is needed for Xen. I am new to both libvirt and Xen. Anyone have any ideas on what's wrong with the following error ? # virt-install --connect=xen:/// -p -d Thu, 15 Mar 2012 10:17:55 DEBUG Launched with command line: /usr/bin/virt-install --connect=xen:/// -p -d Thu, 15 Mar 2012 10:17:55 DEBUG Requesting libvirt URI xen:/// Thu, 15 Mar 2012 10:17:55 ERROR no connection driver available for No connection for URI xen:/// Thu, 15 Mar 2012 10:17:55 DEBUG Traceback (most recent call last): File "/usr/bin/virt-install", line 1004, in <module> sys.exit(main()) File "/usr/bin/virt-install", line 984, in main conn = cli.getConnection(options. connect) File "/usr/lib/python2.6/site-packages/virtinst/cli.py", line 327, in getConnection conn = open_connection(uri) File "/usr/lib/python2.6/site-packages/virtinst/cli.py", line 342, in open_connection open_flags) File "/usr/lib64/python2.6/site-packages/libvirt.py", line 102, in openAuth if ret is None:raise libvirtError('virConnectOpenAuth() failed') libvirtError: no connection driver available for No connection for URI xen:/// By the way, Xen is installed successfully as both "xm list" and "xm info" can output appropriately.

[libvirt-users] Prevent starting a guest concurrently on multiple hosts when using shared storage
by Andreas Ntaflos 16 Mar '12

16 Mar '12

Hi list, Scenario: Libvirt managing KVM-based guests on multiple physical virtualisation hosts. These hosts are attached to some kind of shared storage, be it NFS, GFS2 or whatever. Guest images live on the shared storage so that VMs can be migrated (live or not) between the physical hosts. Basically all Libvirt hosts have definitions of all guests. How can I prevent the same guest from being started on different hosts concurrently, either by accident or intentionally? As far as I can see there is no locking or similar mechanism that would indicate to the Libvirt daemon that a guest (and its VM image) is already running on/in use by another host. This might be a very basic question but I can't seem to find a satisfying answer. Is it even possible? Or does using a shared storage mean that one has to be really, really careful what to start, and where? Is this even something for which Libvirt should be responsible? Any insight is appreciated. Thanks, Andreas

[libvirt-users] Host does not support virtualization type 'xen'
by Su Zhang 15 Mar '12

15 Mar '12

Hello Community, I successfully installed and run xen (xm list and xm info (but virt_caps only has hvm) can output appropriately). However, while I was installing domU image by using virt-install -p at domU OS. I encountered an error information" Host does not support virtualization type 'xen' ". I built xen from source. Some of my friends have the same issue, but if they use pre-build xen, the issue will go away. However, I want to insist in using my version of xen (build from source). Does anyone can give any hint about this error? I asked the same question at xen community and they said this is not a issue from xen but libvirt. Meanwhile they told me I need to rebuild libvirt to adapt my current version of Xen. However, after I re-build xen (download, decompress, ./configure, make, make install), the error is still there. Can anyone let me know if I built the libvirt correctly? Do I need to do anything specific to my current version (4.1.2) of Xen? I'll appreciate if any suggestions can be given, Thanks, -- Su Zhang Ph.D Candidate Computing and Information Sciences Kansas State University

[libvirt-users] Setup a network
by Felix Blanke 15 Mar '12

15 Mar '12

Hello, this isn't a bug report or an advanced usage question. This is just a question from a noob who is new to kvm and needs some help to setup a network between the host and the guests. If you're willing to spend a little time to help me out please continue reading :) See the attached image for more information. I have a host running with a public ip adress. I want to setup some vm for different tasks (webserver, mailserver, database, fileserver). I need to setup a network where the host can speak to the guests, the guest can speak to each other and the guests can speak to the host (meaning to the internet). The host also works as a firewall. Some examples: A) A package for the webserver (port 80) needs to be routed fron the host to the vm1. B) The mailserver needs to access the database. C) The mailserver needs to access the internet for sending an email. So every vm needs one interface. I don't know if it would work if I setup one virtual switch for the guest interconnections and use the host as a router to route the different ports to the vm interfaces. I hope this wasn't so confusing :) What would be the best way to accomplish my goal using virt-install and virsh. Thanks for everyone who is trying to help me out. Kind regards, Felix

For libvirtd log, yeah, it will be very big if you set a low debugger level such as level 1, but as usual, we need also some debugger information except for error, maybe, you can filter some important information or set debugger level to higher level to avoid a big size log file. in addition, if you're run virt-manager please close it, otherwise, libvirt will record many debugger information into libvirtd.log. BTW, if you don't want log file eat your the whole disk space, please remember to change libvirtd.conf debugger level then remove libvirtd.log and restart libvirtd service.

[libvirt-users] virsh create error : monitor socket did not
by 张光鹏 15 Mar '12

Hi, Occasionally I run into this situation , i created a vm-template and i use "virsh create vm-template " to start a vm .After a pause , i got this error : virsh create error : monitor socket did not ; Then i try again with the same template and the same command , my vm created successfully. I try to find something in the file of /var/log/libvrit/qemu/vm-template.log, but i cannot find useful things except some parameters. So , i wonder whether my host running vms too much ? I make sure that my template is right, and this error occasionally appear a few times. Can someone teach me ? Thanks.

[libvirt-users] Weird behavior with LVM storage pool on host
by Ernesto Domato 14 Mar '12

14 Mar '12

Hi list, the problem that I'm having seems to be between libvirtd and udev I have two hosts with LVM. The root partition run over this LVM. After booting the machine, if I do "udevadm settle" it responds almost instantly but then if I launch libvirtd the "udevadm settle" command doesn't respond for about 2 to 3 minutes and the only way to solve this is to restart the uded daemon. This behavior happens on both hosts. The only difference between both is that one has the root partition and storage pool over the same LVM group and disk. The other has separate disks and LVM groups. Have someone experienced something like this or can help me how to debug and solve this problem?. Thanks for all. Ernesto
