[libvirt-users] virsh list not working with xen 4
by Rogério Vinhal Nunes 21 Sep '12

21 Sep '12

Hi, I'm having some trouble to get libvirt to show the correct power state of my virtual machines. I'm using Ubuntu 10.04 + Xen 4.1.1 + libvirt 0.8.8. virsh list --all only shows turned off machines registered in xend. If I turn them on, they just "disappear", and when I start machines directly from xml, they just doesn't appear at all. Libvirt is correctly connecting to xen as I can use the other commands fine, just the list option doesn't seem to work at all. What can I do to change that? # virsh version Compiled against library: libvir 0.8.8 Using library: libvir 0.8.8 Using API: Xen 3.0.1 Running hypervisor: Xen 4.1.0

[libvirt-users] converting save/dump output into physical memory image
by Andrew Tappert 05 Jun '12

05 Jun '12

A lot of people in the security community, myself included, are interested in memory forensics these days. Virtualization is a natural fit with memory forensics because it allows one to get access to a guest's memory without having to introduce any extra software into the guest or otherwise interfere with it. Incident responders are particularly interested in getting memory dumps from systems they're investigating. Virsh has "save" and "dump" commands for storing the state of a guest to a file on disk, but memory of KVM guests doesn't get saved in the "standard" input format for memory forensics tools, which is a raw physical memory image. (This is what you'd get via the classical "dd /dev/mem" approach or the contemporary equivalent using the crash driver; and VMware Server and Workstation produce .vmem files, which are such raw physical memory images, when a guest is paused or snapshotted.) In order to analyze the memory of Libvirt/KVM guests with my Linux memory forensics software, Second Look, I've created a tool for converting Libvirt-QEMU-save files (output of virsh save command) or QEMU-savevm files (output of virsh dump command) to raw physical memory images. I've got a basic working capability, though I'm still tracking down some problems with a guest allocated 8GB RAM--not all the memory seems to be present in the save or dump file. And I haven't tested very extensively yet, version support is limited to what I myself am currently running, etc. I'd like to know if this is a capability that others are interested in. Is this something that would be of interest to the Libvirt project if I were to contribute the code, or to the KVM project, or do you think it best exists as a separate project? I've also got a proof-of-concept tool for converting hibernate images to raw physical memory images. Perhaps a collection of tools for converting various memory dump formats would be a good project. Anyone else interested in this kind of stuff? As an author of commercial memory forensics software I've got a vested interest in availability of good memory acquisition capabilities. But there are a number of people working on FOSS Linux memory analysis tools, too... Andrew

[libvirt-users] Network questions
by paul.worner＠thomsonreuters.com 06 Feb '12

06 Feb '12

Hi all, When creating a new network: 1) Is there a way to disable automatic spawning of dnsmasq on network creation? I read that leaving out the <DHCP> section should accomplish this, but that is not what I am seeing. 2) Is there a way to disable automatic installation of iptables rules? 3) For that matter, what is the purpose of the default iptables rule set? Doesn't line 3 let all traffic pass anyway? Thanks, Paul Running libvirt 0.9.2 on Ubuntu 11.10 server.

[libvirt-users] How to use virt-install and http to install openbsd VM in KVM?
by Li, David 01 Dec '11

01 Dec '11

Hi, Not quite sure if this is the right forum for this question. My requirement is to http boot openbsd in KVM. This works fine with RHEL6 guest install but not with OpenBSD. I loop mounted the openbsd installer on the http server. My Http server directory looks like: [root@uefiserver vm-openbsd]# ll total 5 drwxr-xr-x 3 root kmem 2048 Aug 17 09:35 5.0 drwxr-xr-x 2 root kmem 2048 Aug 17 09:35 etc -r--r--r-- 1 root root 82 Aug 17 09:35 TRANS.TBL My browser can see this directory no problem. And KVM output: [root@lid-hs22-2 ~]# virt-install --hvm --connect qemu:///system --network=bridge:br0 --location=http://10.10.36.134/vm-openbsd/ --name=vm5-openbsd --ram=2048 --vcpus=2 --os-type=unix --file=/var/lib/libvirt/images/vm5-openbsd.img --file-size=20 ERROR Error creating cdrom disk: Could not find an installable distribution at 'http://10.10.36.134/vm-openbsd/' The location must be the root directory of an install tree. [root@lid-hs22-2 ~]# IS this supported? Did I use the right semantics? Thanks. - David

Hi, I am trying to set up vmchannel between the host and guest os. However, "sudo virsh start vm1" always gave me this error: ************************************************************* error: Failed to start domain vm1 error: internal error Process exited while reading console log output: char device redirected to /dev/pts/5 bind(unix:/tmp/foo): Permission denied chardev: opening backend "socket" failed ************************************************************* Related xml is: ************************************************************* <channel type='unix'> <source mode='bind' path='/tmp/foo'/> <target type='virtio' name='channel.port.0'/> <address type='virtio-serial' controller='0' bus='0' port='1'/> </channel> ************************************************************* I can succeed while I manually run the guest os by: ************************************************************* sudo kvm -device virtio-serial \ -chardev socket,path=/tmp/foo,server,nowait,id=foo \ -device virtserialport,chardev=foo,name=org.fedoraproject.port.0\ /path/to/vm1.img ************************************************************* I also noticed that libvirt is able to create socke /var/lib/libvirt/qemu/vm1.monitor every time.

[libvirt-users] virt-manager / ssh (publickey)
by Shaun Glass 29 Nov '11

29 Nov '11

Good day All, I have experienced the following ... I have a rhel 6.1 server running qemu-kvm. I have setup my desktop for a publickey login (root user) to said server so that I may manage the server (qemu-kvm) via the desktop with virt-manager. However, I connect just fine, but cannot create vm's. I get : "No hypervisor options where found for this connection" My laptop does run qemu-kvm via virt-manager and so I decided to setup a publickey login as before and guess what ... I can create vm's. It seems virt-manager bases the creation of vm's based on the hardware / software of the machine it is launched from and not the machine it is connecting to. Is there a workaround / config change etc that can be done so that virt-manager uses the hardware / software configuration of the system it is connecting to ? Regards Shaun Glass

[libvirt-users] Failed to start a "virtual machine " service on RHCS in CentOS 6
by xuteng 25 Nov '11

25 Nov '11

Hi， All: I have two physical machines as KVM hosts (clusterA.RHCS and clusterB.RHCS) , an iscsi target set into GFS. All I want is a HA Cluster which could migrate all the virtual machines on a node to another when the first node failed into some error status. So I created a cluster "cluster" using RHCS ,added the two hosts into the cluster . created a fence device . for every virtual machine on clusterA , create a service ,added a resouce which type is "virtual machine" , and set it's properties. But when I start the service ,I got these errors in /var/log/message : [root@clusterA ~]# tail -f /var/log/messages Nov 24 16:19:29 clusterA libvirtd: Could not find keytab file: /etc/libvirt/krb5.tab: Permission denied Nov 24 16:19:30 clusterA modclusterd: startup succeeded Nov 24 16:19:48 clusterA rgmanager[6754]: Executing /etc/init.d/httpd status Nov 24 16:19:56 clusterA modcluster: Starting service: wuguang-xp on node Nov 24 16:19:56 clusterA rgmanager[2198]: Stopping service vm:wuguang-xp Nov 24 16:19:56 clusterA rgmanager[6850]: Using /etc/libvirt/qemu/wuguang-xp.xml instead of searching /etc/libvirt/qemu Nov 24 16:19:56 clusterA rgmanager[6906]: xend/libvirtd is dead; cannot stop wuguang-xp Nov 24 16:19:56 clusterA rgmanager[2198]: stop on vm "wuguang-xp" returned 1 (generic error) Nov 24 16:19:56 clusterA rgmanager[2198]: Marking vm:wuguang-xp as 'disabled', but some resources may still be allocated!

[libvirt-users] Difference between "Max Memory" and "Used Memory"
by Jérôme Gallard 23 Nov '11

23 Nov '11

Hello, I am new on this mailing list, so If I do something wrong, don't hesitate to tell me :-) I am using the following version of libvirt : Compiled against library: libvir 0.8.8 Using library: libvir 0.8.8 Using API: QEMU 0.8.8 Running hypervisor: QEMU 0.14.0 I would like to understand the difference between "Max Memory" and "Used Memory" returned by a "virsh dominfo" command. In my configuration both values are equal. This surprises me because my VM is not using all its memory. Perhaps I miss something ? Thank you very much for your help. Regards, Jérôme

[libvirt-users] libvirt and linux-vserver
by Christian Parpart 23 Nov '11

23 Nov '11

Hi, I was just googling around for linux-vserver support in libvirt, however, only found sad ppl complaining about the fact, that there is still no linux-vserver support in libbirt. Despite the fact, that there was some kind of lag in review by more than one person, why isn't it still in? so... merely two years after? I think once the patched would have been applied, ppl would start using it, and then also report bugs in case there were some not yet found by the author nor the single reviewer :) Best regards, Christian Parpart.

[libvirt-users] Defined VM goes missing in multi-threaded environment.
by Sharad Mishra 18 Nov '11

18 Nov '11

In a multi-threaded environment where multiple threads are trying to get list of all VMs on host, we have seen that at times this list is missing couple of VMs. The code used is fairly simple, it makes three libvirt calls. 1. Call virConnectNumOfDefinedDomains() to get number of defined domains. 2. Call virConnectNumOfDomains() to get a list of active domains. 3. If there are defined domains, then call virConnectListDefinedDomains (conn, (char **)names, n_names), where n_names is the count returned from #1. The count returned from #3 is less than the one returned from #1. I have bumped up the connection count in libvirtd.conf to 100, and using 20 threads. On average I get one missing defined VM every 5 runs of this test. I have 25 running VMs and 8 defined VMs on this host. # rpm -aq | grep libvirt libvirt-python-0.8.7-18.el6_1.1.x86_64 libvirt-0.8.7-18.el6_1.1.x86_64 libvirt-cim-0.5.14-1.el6.x86_64 libvirt-client-0.8.7-18.el6_1.1.x86_64 Its RHEL 6.1 running 2.6.32-131.17.1.el6.x86_64 Regards, Sharad Mishra

[libvirt-users] [libvirt-user] questions about disk driver virtio and charmonitor
by Chang Liu 17 Nov '11

17 Nov '11

hi all, I have two questions about libvirt. At first, how can I write a XML file that libvirt could give me a command that include this: if=virtio. -drive file=/dev/vg.vmms/lvm-v097218.sqa.cm4,if=none,id=drive-ide0-0-0,format=raw -device ide-drive,bus=ide.0,unit=0,drive=drive-ide0-0-0,id=ide0-0-0 event I have let the <target dev=vda bus=virtio> the XML file also make the command not include virtio, it's like this: -drive file=/dev/vg.vmms/lvm-v097226.sqa.cm4,if=none,id=drive-virtio-disk0,format=raw,cache=none -device virtio-blk-pci,bus=pci.0,addr=0x4,drive=drive-virtio-disk0,id=virtio-disk0 and my question is, this is command args could enable virtio? or there is some other XML format could let the if=virtio. Second when I boot the vm in the second step after use the kickstart install it. Once in a while, it occurs an error that: monitor socket did not show up.: No such file or > Traceback (most recent call last): File "/home/lingjiao.lc/vmms/backserv/bin/../lib/virtmgr.py<http://lingjiao.lc/vmms/backserv/lib/virtmgr.py>", line 1007, in request_vm dom.create() File "/usr/lib64/python2.6/site-packages/libvirt.py", line 325, in create if ret == -1: raise libvirtError ('virDomainCreate() failed', dom=self) libvirtError: monitor socket did not show up.: No such file or directory But if I reinstall it, it will be ok. If I install hundreds of VMs once, I think this is a headache. Could anybody help me, how can I disable the charmonitor or solve these problem.

[libvirt-users] consider bios upgrade...
by jurgen.depicker＠let.be 17 Nov '11

17 Nov '11

Dear all, I didn't get any reply, so I send this mail again. On one of my windows Vms (KVM), I get from time to time a 'windows recovered from a serious error' message, and if I click the wonderfully useful (ahum) support link, I reach this page: http://wer.microsoft.com/responses/Response.aspx/1445/en/5.1.2600.2.0001010… I quote the first part of it here: "Consider BIOS upgrade Microsoft is unable to determine the exact cause of this error. However, this problem was most likely caused by an error in your computer’s random access memory (RAM). RAM is the main internal storage area the computer uses to run programs and store data. During the crash analysis, we noticed the basic input/output system (BIOS) version on this computer does not match the specifications for the central processing unit (CPU), also known as a processor, that is installed on your computer. This can occur when a newer processor is installed on an older system board or older BIOS. Using a BIOS that does not support the installed processor can result in Windows system crashes. Contact your computer manufacturer or motherboard manufacturer for an updated version of BIOS for your computer's processor." Now I'm not sure what this is all about: how can I possibly upgrade my VM's BIOS, or should I do something else? Can it have something to do with the processor specs in the VM's XML definition? Thanks for looking into this, Jürgen

[libvirt-users] Checking if the VM has been created
by Preethi Ramesh 17 Nov '11

17 Nov '11

I'm a Libvirt newbie and I'd really appreciate it if someone could answer my doubts. I'm using Libvirt's Java API. My doubts: 1.Currently, I'm able to create a VM on Ubuntu 11.04 using Libvirt functions domainCreateLinux() and domainDefineXML(). Apart fromt the boolean return status of these operations and running the virsh list command, is there any way to SSH in (login) to the newly created VMs and run applications on them? I tried running virsh console but nothing comes up. Also I tried fixing the XML file to accommodate the console operation( link <http://ubuntuforums.org/showthread.php?t=1159220>) but that was unsuccessful too. 2. If yes, how can I get the IP of the VM created? 3. Is there any function to create image files(in any format qcow or qcow2) using Libvirt API? Right now, I'm using a shell script which creates the image from it's iso. Thanks in advance P Ramesh

[libvirt-users] Speaking of DNSmasq ....
by William A. Mahaffey III 17 Nov '11

17 Nov '11

.... I am getting a bit tired of those pesky DNSmasq entries in my syslog file, they fill it up about weekly, wash other stuff out of view on a tail. Is there any way to suppress them. or else increase their lease time so that they happen less frequently ? Having a finite lease time for a VM seems nonsensical, it can't go anywhere or disconnect (obviously) .... I tried restarting DNSmasq, but it said 'Socket busy' or some such & didn't restart. Someone on another list said that DNSmasq was/is in fact started by libvirt/KVM/QEMU, & I poked around in the various /etc/sysconfig files, but couldn't find anything related to DNSmasq, whatever options it is started with seem to be hardwired or compiled into one of the pertinent executables .... FC 14, 64 bit, terminally patched up, libvirt 0.8.3-10.fc14 64-bit, qemu-KVM 2:0.13.0-1.fc14 64-bit .... TIA .... -- William A.

[libvirt-users] virsh Attach-disk function
by Jatin Kumar 16 Nov '11

16 Nov '11

Hello, I have to use attach-disk function for providing additional storage to the guest domain but i couldn't found proper documentation anywhere which i can follow. ---- For linux (Ubuntu 11.10 server edition, 64bit) guest i tried qemu-img create -f qcow2 disk.qcow2 size virsh attach-disk guest_name --driver file disk.qcow2 sdc Both of the above commands are working fine but when i try to format the drive from inside linux then its size reduces to few KB. Before formatting qemu-img info reports correct info(as expected, correct virtual size) but after formatting the even qemu-img info reports its actual size(few KB) not virtual size. ----- For windows (Windows 2008 Server R2) guest, i tried qemu-img create -f raw disk.img size virsh attach-disk guest_name --driver file disk.img vdb virsh shows that the disk is attached successfully, but i cannot find any disk attached from inside the guest (in storage management). I tried rebooting the guest but same problem. Is there anything that i am doing wrong or missing. -- Jatin Kumar

Hey all, I've been trying to make listDomains() work on Xen but it simply returns an array of null values. Also, while displaying the length of the array returned by listDomains(). Upon using the same function in KVM, I'm able to retrieve the complete array of active machines. I'm positive that active Xen machines are running(cross checked it with xm list). I've been posting this for quite sometime now but haven't received any reply which could debug my code. I'd really appreciate it if someone could help me. Thanks, P Ramesh

[libvirt-users] kvm/libvirt can't use vmdk files? qemu: 'vmdk' invalid format
by Frank Hauptle 15 Nov '11

15 Nov '11

Hi all, I have a RHEL6.1 qemu-kvm hypervisor running a raw image that I need for various reasons to convert to vmdk. I used this process: qemu-img convert server3.img -O vmdk server3.vmdk Then I edited the XML file (/etc/libvirt/qemu/server3.xml) like so: <devices> <emulator>/usr/libexec/qemu-kvm</emulator> <disk type='file' device='disk'> <driver name='qemu' type='vmdk'/> <source file='/raid5/images/guilder3.vmdk'/> <target dev='hda' bus='ide'/> <address type='drive' controller='0' bus='0' unit='0'/> </disk> Which basically means that I changed raw to vmdk in this line: <driver name='qemu' type='vmdk'/> but when I try to start the VM, I get this: Error starting domain: internal error Process exited while reading console log output: char device redirected to /dev/pts/5 qemu: 'vmdk' invalid format Traceback (most recent call last): File "/usr/share/virt-manager/virtManager/asyncjob.py", line 45, in cb_wrapper callback(asyncjob, *args, **kwargs) File "/usr/share/virt-manager/virtManager/engine.py", line 959, in asyncfunc vm.startup() File "/usr/share/virt-manager/virtManager/domain.py", line 1128, in startup self._backend.create() File "/usr/lib64/python2.7/site-packages/libvirt.py", line 330, in create if ret == -1: raise libvirtError ('virDomainCreate() failed', dom=self) libvirtError: internal error Process exited while reading console log output: char device redirected to /dev/pts/5 qemu: 'vmdk' invalid format This bit is telling: qemu: 'vmdk' invalid format As a test I tried using libvirt to create a vmdk and then add it to an existing VM, and it failed with the same message. Does this mean that libvirt supports vmdk, but qemu-kvm doesn't? IF so, why does libvirt continue to offer it as an option for KVM VM's?? IF this isn't related to libvirt, I apologise, but I'd appreciate any pointers. kindest regards Frank UWA

[libvirt-users] Problem with listDomains() in Xen
by PREETHI RAMESH 12 Nov '11

12 Nov '11

This question concerns the usage of the listDomains(). When I run this piece of code in KVM, it works perfectly fine but throws an array out of bounds exception in Xen. Connect conn=null; conn = new Connect("xen:///", true); int[] id = conn.listDomains(); System.out.println("lD of VM " +id[0]); Answer I'd got: Well, your code assumes that id.length is >= 1, but listDomains() can return an empty array when there are no active domains known to libvirt. So you need to check id.length before accessing any element in the array. Follow up- I tried accessing the length of the array and it's 0 all the time. And there are active domains available. In fact, I'm able to getUUID from the domain name. Other functions work fine too. Am I missing something?Can someone please help me? Thanks!

[libvirt-users] How to create virtual machine via virsh shell?

Hi, I recently in the study of the knowledge of the libvirt(version 0.9.6) and vmware(esx,esxi,vcenter,vspheere client), I use virshshell doing some work such as create virtual machine(but i get an error like "the connetc driver do not support") , define virtual machine(success but when i start it i get an error like "can not find vmdk file 或其所依赖的快照磁盘之一"). Then I realized to first create a volume , but I again meet a mistake like "internal error Could not create volume: NotImplemented".

[libvirt-users] Can't assign the 2nd MAC address to the VM
by zhouyb13＠sina.com 10 Nov '11

10 Nov '11

to all who read this message, I can't assign the second MAC to the second NIC for a VM. If only use 1 NIC, assigning MAC works. But not for 2 NICs or more. Do anyone has any ideas? I have installed KVM on Ubuntu 11.10 64bit on my laptop. Also created the bridge on the host, and also taps. I created a RHEL 6.1 64bit VM on this environment and run: sudo kvm -m 512 -drive file=/data/vm/kvm/hslt/rhel61_x64_1st,cache=writeback -boot order=c -localtime -net nic,model=virtio,vlan=1,macaddr=52:54:00:12:34:56 -net tap,vlan=1,ifname=tap2,script=no -net nic,model=virtio,vlan=1,macaddr=52:54:00:12:34:55 -net tap,vlan=1,ifname=tap3,script=no It doesn't work and the VM can NOT start. If I change the command to: sudo kvm -m 512 -drive file=/data/vm/kvm/hslt/rhel61_x64_1st,cache=writeback -boot order=c -localtime -net nic,model=virtio,vlan=1,macaddr=52:54:00:12:34:56 -net tap,vlan=1,ifname=tap2,script=no -net nic,model=virtio,vlan=1 -net tap,vlan=1,ifname=tap3,script=no The VM can start, but the second NIC doesn't work in guest VM, and showing like no such device. After change it to: sudo kvm -m 512 -drive file=/data/vm/kvm/hslt/rhel61_x64_1st,cache=writeback -boot order=c -localtime -net nic,model=virtio,vlan=1 -net tap,vlan=1,ifname=tap2,script=no -net nic,model=virtio,vlan=1 -net tap,vlan=1,ifname=tap3,script=no It works well, with 2 NICs in guest VM.

[libvirt-users] Problem with libvirt daemon
by Wouter - Iamotor 10 Nov '11

10 Nov '11

Hello, I have a problem with the libvirt daemon. I have a little php script which should connect with libvirt, but it won't. When I try to start the libvirt daemon I get this error (using the command libvirtd --listen): 2011-11-09 19:35:18.095: 3560: info : libvirt version: 0.9.7 2011-11-09 19:35:18.095: 3560: error : virPidFileAcquirePath:345 : Failed to acquire pid file '/var/run/libvirtd.pid': Resource temporarily unavailable So the daemon won't start and isn't started yet. If I check if the service is running with ps -ef | grep libvirtd I get this output: root 2865 1 0 15:50 ? 00:00:00 /usr/sbin/libvirtd -d root 3149 1 0 19:17 ? 00:00:00 libvirtd -d root 3206 1 0 19:17 ? 00:00:00 libvirtd -dl root 3300 1 0 19:20 ? 00:00:00 libvirtd --listen --daemon root 3356 1 0 19:21 ? 00:00:00 libvirtd --listen --daemon root 3564 3077 0 19:36 pts/0 00:00:00 grep --color=auto libvirtd Here you can see that the service isn't running. How can I fix this problem. There is a .pid file in the /var/run/ directory. I already deleted it and used the command libvirtd -daemon -listen but it won't start. It doesn't show any output but when I use the ps -ef command, I see that the service is not running. Can you please help me? With kind regards, Wouter.

[libvirt-users] libvirt, OSX and VirtualBox - how?
by Brian Candler 09 Nov '11

09 Nov '11

I have a new OSX Lion Macbook and would like to control VirtualBox using "virsh" (as I do with KVM under Ubuntu). I've got this far: * Installed VirtualBox * Installed libvirt (brew install libvirt) But now I'm a bit stuck :-) I ran VirtualBox itself, and created a test VM successfully. If I try to use virsh, this is what I get: Brians-MacBook-Air:~ $ virsh -c vbox:///session error: internal error unable to initialize VirtualBox driver API error: failed to connect to the hypervisor Brians-MacBook-Air:~ $ virsh -c vbox+unix:///session error: Failed to connect socket to '@/Users/brian/.libvirt/libvirt-sock': No such file or directory error: failed to connect to the hypervisor If I try to start libvirtd, this is what I get: Brians-MacBook-Air:~ $ /usr/local/sbin/libvirtd 00:00:18.970: -1: info : libvirt version: 0.9.6 00:00:18.970: -1: error : virNetSocketNewListenUNIX:340 :

In the future it is usually best to keep one of the lists on an email; that way, if I'm away or not responding, someone else can help you. I've added libvirt-users to this response. In any case, you have the right idea. Libvirt is a control plane for various different virtualization solutions. Arguably the most popular virtualization solution that libvirt can control is KVM, but it can also manage Xen, VMware ESX, LXC (linux containers), UML, etc. Libvirt provides both tools (like virsh and libvirtd) and APIs for interacting with virtual machines. The APIs are things like virDomainShutdown(), virDomainReboot(), etc. The ruby-libvirt package is a thin wrapper around these APIs, so that you can use this functionality from ruby programs. That is, you would be able to do something like: dom.reboot dom.shutdown from your ruby programs. There are also bindings for other languages such as python, php, and perl. There is a lot more information at http://libvirt.org, and there is more information specifically about the ruby bindings at http://libvirt.org/ruby -- Chris Lalancette

[libvirt-users] Finding out if Xen or KVM is used
by PREETHI RAMESH 06 Nov '11

06 Nov '11

I've got 2 doubts: 1.I've been trying to write an application using Libvirt's Java API which should run on both Xen and KVM running machines and execute the Xen or KVM code based on the hypervisor used. I want the physical machine to know if it's running Xen or KVM and execute only that code. While using getURI(), I need to use it as conn.getURI() but then I can't use conn without declaring it previously as Connect conn=new Connect("URI"); Is there any way to get the URI used and hence the hypervisor used? 2. This question concerns the usage of the listDomains(). When I run this piece of code in KVM, it works perfectly fine but throws an array out of bounds exception in Xen. Connect conn=null; conn = new Connect("xen:///", true); int[] id = conn.listDomains(); System.out.println("lD of VM " +id[0]); Thanks for your time. P Ramesh

[libvirt-users] Libvirt exiting and respawning
by Stephen Eilert 06 Nov '11

06 Nov '11

Hi, I'm trying to use Libvirt with LXC, under Ubuntu 11.04, but I can't get it to work. It keeps exiting and being restarted by upstart. Log file follows. It appears that it is complaining, among other things, of QEMU. I am not running QEMU and would like to disable everything except for LXC, but I am not sure it would fix my issue. I've set the log level to debug, even, but didn't see anything out of ordinary. Even resorted to strace, but I don't know enough about libvirtd to try and understand its behavior. Anyone got any clue about what's causing it to decide to exit? # libvirtd --version libvirtd (libvirt) 0.9.2 # uname -a Linux CI-Server-3-Backend-2 2.6.35.4-rscloud #2 SMP Sat Oct 29 21:16:49 UTC 2011 x86_64 x86_64 x86_64 GNU/Linux # lxc-checkconfig --- Namespaces --- Namespaces: enabled Utsname namespace: enabled Ipc namespace: enabled Pid namespace: enabled User namespace: enabled Network namespace: enabled Multiple /dev/pts instances: enabled --- Control groups --- Cgroup: enabled Cgroup namespace: enabled Cgroup device: enabled Cgroup sched: enabled Cgroup cpu account: enabled Cgroup memory controller: enabled Cgroup cpuset: enabled --- Misc --- Veth pair device: enabled Macvlan: enabled Vlan: enabled File capabilities: enabled # cat /var/log/syslog Nov 5 18:42:50 CI-Server-3-Backend-2 libvirtd: 18:42:50.696: 25820: info : libvirt version: 0.9.2 Nov 5 18:42:50 CI-Server-3-Backend-2 libvirtd: 18:42:50.696: 25820: info : networkReloadIptablesRules:1410 : Reloading iptab les rules Nov 5 18:42:50 CI-Server-3-Backend-2 libvirtd: 18:42:50.776: 25820: error : virCommandWait:1393 : internal error Child proce ss (/sbin/iptables --table mangle --delete POSTROUTING --out-interface virbr0 --protocol udp --destination-port 68 --jump CHE CKSUM --checksum-fill) status unexpected: exit status 1 Nov 5 18:42:50 CI-Server-3-Backend-2 libvirtd: 18:42:50.817: 25820: error : virCommandWait:1393 : internal error Child proce ss (/sbin/iptables --table mangle --insert POSTROUTING --out-interface virbr0 --protocol udp --destination-port 68 --jump CHE CKSUM --checksum-fill) status unexpected: exit status 1 Nov 5 18:42:50 CI-Server-3-Backend-2 libvirtd: 18:42:50.818: 25820: warning : networkAddGeneralIptablesRules:1199 : Could not add rule to fixup DHCP response checksums on network 'default'.

[libvirt-users] general protection errors
by Alex 02 Nov '11

02 Nov '11

Hi, Some time ago I sent a message about some general protection errors, and didn't receive a response. I hoped I could post again and that someone might have some ideas. I really don't think it is a hardware problem producing these errors, but am otherwise out of ideas. I'm having a problem with a fedora15 x86_64 host with a fedora15 x86_64 guest on a Xeon E3-1240 with 8GB RAM on the guest. This is the only guest. The server is configured as a mail server, using spamassassin, postfix, amavisd, and clamav. Have there been significant changes in the current version from 0.8.8 that is shipped with fedora15? It was previously running without error on different hardware. I migrated the disks to a more powerful server due to load. It's a new server, and has been stress tested with memtest86, mprime, and passmark's Linux test for more than 24 hours without producing a problem. However, when I run the kvm vm, I receive a bunch of errors similar to these on the guest: [169245.360511] clamscan[27448] general protection ip:7f125f2e6ffb sp:7fff117566f0 error:0 in libclamav.so.6.1.11[7f125f229000+9ce000] [29016.445470] clamd[1110] general protection ip:30df2c3981 sp:7fffa08f4fe0 error:0 in libclamav.so.6.1 .11[30df200000+9ce000] There are other applications, such as pyzor, that produce similar errors. Is this something that could be a result of some software configuration error I've made? Is there something I can do to debug this further? There also aren't any errors on the host indicating a kernel problem or hardware issue. Is it possible this is a known error? I was previously trying to improve IO performance by using 'block' instead of 'file' for the device, but had to abandon that idea because it didn't work and I had to concentrate on this problem. Could disabling the cache (cache=none) cause this? I've included some info below, in hopes someone could guide me towards a solution. # rpm -qva|egrep 'kvm|libvirt|kernel|qemu' libvirt-python-0.8.8-7.fc15.x86_64 kernel-2.6.40.6-0.fc15.x86_64 qemu-img-0.14.0-8.fc15.x86_64 gpxe-roms-qemu-1.0.1-4.fc15.noarch kernel-2.6.40.4-5.fc15.x86_64 qemu-system-x86-0.14.0-8.fc15.x86_64 libvirt-0.8.8-7.fc15.x86_64 libvirt-client-0.8.8-7.fc15.x86_64 qemu-common-0.14.0-8.fc15.x86_64 kernel-headers-2.6.40.6-0.fc15.x86_64 qemu-kvm-0.14.0-8.fc15.x86_64 I've included my domain config below in hopes it helps. <domain type='kvm'> <name>mail02</name> <uuid>ec4f3cf5-2f27-fb3e-72f6-3fa3176b13b6</uuid> <memory>6291456</memory> <currentMemory>6291456</currentMemory> <vcpu>4</vcpu> <os> <type arch='x86_64' machine='pc-0.14'>hvm</type> <boot dev='hd'/> </os> <features> <acpi/> <apic/> <pae/> </features> <clock offset='utc'/> <on_poweroff>destroy</on_poweroff> <on_reboot>restart</on_reboot> <on_crash>restart</on_crash> <devices> <emulator>/usr/bin/qemu-kvm</emulator> <disk type='file' device='disk'> <driver name='qemu' type='raw' cache='none'/> <source file='/var/lib/libvirt/images/mail02.img'/> <target dev='vda' bus='virtio'/> <address type='pci' domain='0x0000' bus='0x00' slot='0x05' function='0x0'/> </disk> <disk type='block' device='cdrom'> <driver name='qemu' type='raw'/> <target dev='hdc' bus='ide'/> <readonly/> <address type='drive' controller='0' bus='1' unit='0'/> </disk> <controller type='ide' index='0'> <address type='pci' domain='0x0000' bus='0x00' slot='0x01' function='0x1'/> </controller> <interface type='bridge'> <mac address='52:54:00:67:2c:4c'/> <source bridge='br0'/> <model type='virtio'/> <address type='pci' domain='0x0000' bus='0x00' slot='0x03' function='0x0'/> </interface> <serial type='pty'> <target port='0'/> </serial> <console type='pty'> <target type='serial' port='0'/> </console> <input type='mouse' bus='ps2'/> <graphics type='vnc' port='-1' autoport='yes'/> <video> <model type='cirrus' vram='9216' heads='1'/> <address type='pci' domain='0x0000' bus='0x00' slot='0x02' function='0x0'/> </video> <memballoon model='virtio'> <address type='pci' domain='0x0000' bus='0x00' slot='0x06' function='0x0'/> </memballoon> </devices> </domain> Thanks, Alex

[libvirt-users] auto-set /cgroup/*/libvirt/qemu/<vm name>/ directory permissions on creation
by Ben Clay 02 Nov '11

02 Nov '11

Is there a way to automatically set the permissions of cgroups directories created by libvirt when a VM is launched? Although it looks like I can set permissions on top-level /cgroup directories via cgconfig.conf, the cgconfig.conf manpage says "Permissions are related only to enclosing control group and are not inherited by subgroups.". From this, I believe that when libvirt creates VMs, the new directories under /cgroup/*/libvirt/qemu/<vm name>/ will not receive the cgconfig.conf permissions. Where in the libvirt config can I set this? We need users other than root to write to specific subsystems. I can ask on the libcg mailing list as well, but I thought I'd try here first since libvirt is dynamically creating / destroying these groups. Thanks.

[libvirt-users] Hard limit for the cpu usage of a VM
by sethuraman subbiah 01 Nov '11

01 Nov '11

Hi , I was previously using xen and currently moved to KVM. I am using libvirt to manage these VMs. In den's credit scheduler , I had the ability to set a cap on the cpu usage for a VM. But I was not able to find a similar substitute in KVM. I find that we can use cgroups to provide shares for VM but that will be more like weight based and it doesn't set a hard cap for that VM. I tried using cpulimit but I find it inaccurate and we can give values only between 0-100. Thus, I think it cannot support multi core environments. Can any one suggest a method to set a hard limit on a VM's cpu usage? Thank you. - Regards, Sethuraman Subbiah Graduate Student - NC state University M.S in Computer Science
