[libvirt-users] Updates to cucmber-vhost - guineapigs wanted! :)
by Matthew Macdonald-Wallace 05 Oct '10

05 Oct '10

Hi all, For those of you that are using cucumber for Continuous Integration or similar I've created a set of steps that enable you to use cobbler and cucumber to auto-provision using Libvirt. I've just made some changes to the code however I don't have access to all the hardware/software required to test it fully. If you are able to, please check out the code from http://tinyurl.com/virtcuke (my github repo) and test, posting bugs against the project. Thanks in advance, Matt

[libvirt-users] virDomainSetSchedulerParameters() does not support KVM?
by Zhang Qian 30 Jul '10

30 Jul '10

Hi, I have one RHEL 5.5 Xen box and one RHEL 5.5 KVM box. In the Xen box, the following command works well: $ virsh schedinfo RHELu3T Scheduler : credit weight : 256 cap : 0 But in KVM box, it can not work: $ virsh schedinfo RHEL5u3 Scheduler : Unknown error: this function is not supported by the hypervisor: virDomainGetSchedulerType Is it because that the libvirt APIs virDomainGetSchedulerParameters() and virDomainSetSchedulerParameters() does not support KVM? Is there any plan for libvirt to support that? Or any equivalent in libvirt can be used to do the same thing for KVM？ Thanks! Qian

[libvirt-users] Too many active clients?
by jeremy avnet 29 Jul '10

29 Jul '10

Hello, I'm receiving a lot of these since a couple of days ago: libvirtd: 16:30:10.960: error : qemudDispatchServer:1282 : Too many active clients (20), dropping connection I'm trying to figure out where all these active clients are coming from. I have a daemon running the interacts with libvirtd, but it only creates two long-lived connections (I'm very sure). What constitutes an active connection? The only other libvirtd access that goes on are some quick lived munin process which connect in various ways and using virsh on the command line. Libvirt version 0.7.5-5ubuntu27 on Ubuntu 10.04. Thanks! .:. jeremy

[libvirt-users] Hello world help needed
by Dale Amon 29 Jul '10

29 Jul '10

I am trying to work my way up the learning curve through a forest of conflicting and mostly non-working examples and help pages spread about the internet. I have had no trouble getting a basic vm to build and to then start it up. But I have utterly failed to gain access to the machine. The only host I have available that can run it is a remote server. I have not got the networking side working yet, but I can live with that for the moment because I have thus far not been able to get access to a simple console on the vm. Here is the machine: <domain type='kvm' id='2'> <name>ubuntu</name> <uuid>8904d893-87dc-dc1f-0219-486745a370f6</uuid> <memory>262144</memory> <currentMemory>262144</currentMemory> <vcpu>1</vcpu> <os> <type arch='x86_64' machine='pc-0.12'>hvm</type> <boot dev='hd'/> </os> <features> <acpi/> </features> <clock offset='utc'/> <on_poweroff>destroy</on_poweroff> <on_reboot>restart</on_reboot> <on_crash>destroy</on_crash> <devices> <emulator>/usr/bin/kvm</emulator> <disk type='file' device='disk'> <source file='/home/myhome/ubuntu-kvm/tmpl3Xutj.qcow2'/> <target dev='hda' bus='ide'/> </disk> <interface type='network'> <mac address='52:54:00:be:d5:c2'/> <source network='default'/> <target dev='vnet0'/> <model type='virtio'/> </interface> <input type='mouse' bus='ps2'/> <graphics type='vnc' port='5900' autoport='yes' listen='127.0.0.1'/> <video> <model type='cirrus' vram='9216' heads='1'/> </video> <serial type='pty'> <source path='/dev/pts/2'/> <target port='0'/> </serial> <console type='pty' tty='/dev/pts/2'> <source path='/dev/pts/2'/> <target port='0'/> </console> </devices> <seclabel type='dynamic' model='apparmor'> <label>libvirt-8904d893-87dc-dc1f-0219-486745a370f6</label> <imagelabel>libvirt-8904d893-87dc-dc1f-0219-486745a370f6</imagelabel> </seclabel> </domain> I dumped the original and added the pty stuff from an example, but when I create it and connect to the console: # virsh -c qemu:///system create ubuntu2.xml --console Domain ubuntu created from ubuntu2.xml Connected to domain ubuntu Escape character is ^] nothing appears and nothing I type echoes. At least I can escape though... I seem to have no trouble creating them, but it sure would be nice to be able to access them. Oh, and btw. Every time I create a VM with the ubuntu ubuntu-vm-builder kvm hardy --mem 256 --iso /path/to/ubuntu-8.10-server-i386.iso ubuntu-vm-builder kvm lucid --mem 256 --iso ubuntu-10.04-server-amd64.iso It leaves a loopback disk behind that never goes away. I've had to reboot the server once already and upped loop_max to 32 so I would be able to work longer before doing so again.

[libvirt-users] libvir: Domain error <domName>: invalid argument in virDomainGetXMLDesc
by Priya 23 Jul '10

23 Jul '10

All, I just downloaded and installed libvirt-bin and this is my first email to the group, so I apologize in advance if my questions are too naive! So, I am trying to access VMs running on xen3.2 hypervisor (host with kernel 2.6.24-24-xen) using virt-manager installed on a machine running Ubuntu 9.04 (client machine). I got to the point where I can connect to my virtual machine and my domain-0 through the virt-manager client (meaning that I already have libvirt, ssh-askpass downloaded and the libvirtd and xend running on my host machine), and on the client machine I can view the window showing the statistics of CPU utilization of my domain-0 and user domain. The attachment shows a shapshot of the virt-manager on my client machine. Now when I try to access the GUI of either of domain-0 or the user domain (by selecting the specific domain and clicking open) I get the following error message in a pop-up on my client and in the libvirtd console on the host: "libvir: Domain error xen_2: invalid argument in virDomainGetXMLDesc" I tried to Google this error, but I don't find any clear answers. It seems to be a bug in the libvirt implementation that has been detected and resolved already. And I am confused as to why is it that such a recent version is still buggy? Should I have downloded another version instead? I desperately wish to resolve this problem and would appreciate any guidance. Many thanks! -- Priya Bhat

[libvirt-users] Force network to append iptables rules to end or specified number?
by steven765＠yahoo.com 21 Jul '10

21 Jul '10

Subject line says it all. Every time I restart a network libvirt inserts its standard rules at the head of the ip forward chain. The deny lines in there clobber access to my servers. Is there any way to make it append those rules at a specific number or at the end by default? Many Thanks, Steve

Hello: One of my customers asked for access to stop and start their VPS. Right now, I can do that using virsh, but I do not want to give this customer the ability to stop and start all VPSs running on the host. Is there a way to give stop and start control of one VPS to someone? I am using KVM on a CentOS 5.5 host.

19 Jul '10

Hi, I am running ubuntu 9.10, with kvm and libvirt-bin, etc. Using virsh, I can't live-migrate a VM from host1 to host2. It reports a unknown failure. The VM image is accessible on both source and destination hosts located on a shared storage using nfs. Image directory is on the same path on both hosts. The src and destination hosts are on the same subnet. I can connect to remote host with qemu+ssh but I can't migrate. my configuration is: $ uname -a Linux mahsa1-desktop 2.6.31-21-generic-pae #59-Ubuntu SMP Wed Mar 24 08:47:55 UTC 2010 i686 GNU/Linux $virsh # version Compiled against library: libvir 0.7.0 Using library: libvir 0.7.0 Using API: QEMU 0.7.0 Running hypervisor: QEMU 0.11.0 Connect to the local machine's hypervisor as follows and see the localmachines:$virsh # connect qemu:///system $virsh # list Id Name State -------------------------------- 2 VmLinux11 running 3 VMLinux12 running 4 VmLinux13 running Verify connectivity to the hypervisor of the remote target system asfollows:$virsh connect qemu+ssh://host2name/system Attempt the migration as follows:$virsh migrate --live VmLinux13 qemu+ssh://host2name/system Connecting to uri: qemu:///system root@host2name's password: error: Unknown failure the log file on the source physical host gives this:14:57:13.514: error : remoteIO:7184 : operation failed: migrate failed: migrate "tcp:host2name:49161" migration failed 14:57:13.709: error : remoteIO:7184 : Unknown failure I disable the firewall on both hosts but it doesn't still work. please help me.

[libvirt-users] ESX - How to create a new domain
by George Goh 19 Jul '10

19 Jul '10

Hi, I've been trying to figure out how to create a new domain(create a new virtual machine) using the ESX driver. The documentation at http://libvirt.org/drvesx.html says: To define a new domain the driver converts the domain XML into a VMware VMX file and uploads it to a datastore known to the ESX server. Because multiple datastores may be known to an ESX server the driver needs to decide to which datastores the VMX file should be uploaded. The driver deduces this information from the path of the source of the first file-based harddisk listed in the domain XML. But I can't find a way to do this in virsh. Any ideas? -George

[libvirt-users] how to deactivate an active network with virsh? (and what is that anyway)
by John Lumby 15 Jul '10

15 Jul '10

virsh provides net-start <netname-or-id> to activate an inactive network. Does virsh provide any way to do the exact converse? deactivate an active network without destroying, undefining, removing, ... Also - I am curious - what does activate actually do? What change in state of anything occurs? ( I read the document at http://libvirt.org/formatnetwork.html which the man page referred me to but it had nothing to say on this. I did not try to read the code). John _________________________________________________________________ MSN Dating: Find someone special. Start now. http://go.microsoft.com/?linkid=9734384

[libvirt-users] Blockpeek.. A little help please
by steven765＠yahoo.com 08 Jul '10

08 Jul '10

Hi, I'm trying to use blockpeek to open the contents of a file. Inside the vm i ran debugfs: imap /test/findme and got: inode 32642 is part of block group 4 located at block 131074, offset 0x0100 I try using 0x100 or 256 as the offset to blockpeek into that VM and get nonsense as a result. Am I calculating the offset incorrectly, is there a better way to find a file's location on disk? And then open it? I'm just printing the return as a string from the buffer looping over size. Is that incorrect? Thanks again, Steve

[libvirt-users] ESXi support
by adrian wyssen 03 Jul '10

03 Jul '10

Hello everyone, I want to use libvirt to manage an Vmware ESXi 4.0 server from within a virtual machine running on that server. I did not find any C examples using ESX(i). Can anyone give me some example code, because I am really new in this domain and I can't get started... I don't find any information about using libvirt with ESX(i), even if it is supposed to work with it. I thank you for any information. Adrian

[libvirt-users] ANNOUNCE: ruby-libvirt bindings 0.2.0
by Chris Lalancette 02 Jul '10

02 Jul '10

Hello all, I'm pleased to announce the release of 0.2.0 of the ruby-libvirt bindings. This release has a number of new features: - Updated Storage class, implementing pool.active?, pool.persistent?, pool.vol_create_xml_from - Updated Connect class, implementing conn.node_free_memory, conn.node_cells_free_memory, conn.node_get_security_model, conn.encrypted?, conn.libversion, and conn.secure? - Updated Network class, implementing network.active? and network.persistent? - Update Domain class, implementing conn.domain_xml_from_native, conn.domain_xml_to_native, dom.migrate_to_uri, dom.migrate_set_max_downtime, dom.managed_save, dom.has_managed_save?, dom.managed_save_remove, dom.security_label, dom.block_stats, dom.memory_stats, dom.blockinfo, dom.block_peek, dom.memory_peek, dom.active?, dom.persistent?, dom.snapshot_create_xml, dom.num_of_snapshots, dom.list_snapshots, dom.lookup_snapshot_by_name, dom.has_current_snapshot?, dom.revert_to_snapshot, dom.current_snapshot, snapshot.xml_desc, snapshot.delete, dom.job_info, and dom.abort_job - Implementation of the NodeDevice class - Implementation of the Secret class - Implementation of the NWFilter class - Implementation of the Interface class - Conversion of the development tree to git - New maintainer (me). David Lutterkort has agreed to transfer maintainership of the bindings over to me, since he is not actively involved in their development anymore. With the above list, almost all of the APIs up to and including libvirt 0.8.1 are covered. There are a few that I have not yet had time to implement; you can look at the list of FIXMEs in the source code to find them. I've uploaded new tarballs and source RPMs to: http://libvirt.org/ruby/download/ The new git repo is here: http://libvirt.org/git/?p=ruby-libvirt.git;a=summary The documentation for the new API's are here: http://libvirt.org/ruby/api/index.html If you have time, and are interested in the bindings, please give these new ones a whirl and let me know if they work for you. As usual, if you have any questions, problems, patches, or bug reports, feel free to email the libvirt development list (and CC me) so that I can take a look at them. -- Chris Lalancette

[libvirt-users] C API example
by steven765＠yahoo.com 02 Jul '10

02 Jul '10

Trying to build the hellolibvirt example. I get the project to compile okay but when I try to run it I get: Unable to connect to '/usr/local/var/run/libvirt/libivrt-sock Given libvirt --status says it's in /var/run/libvirt/libvirt-sock that makes sense. How do I make the git version run with my local copy? Or even better does anyone have any example projects that have the proper includes documented, seperate from the build tree? I'd like to just use the API not compile and deal with all of libvirt at the moment. Thanks a ton!
