[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 04 Jun '12

04 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. Here's the libvirt network config: RAW CONFIG <network> <name>test</name> <bridge name="virbr%d" stp="off" delay="0"/> <forward mode="route"/> <ip address="192.168.0.1" netmask="255.255.255.0"> </ip> </network> COMMAND virsh net-create test.xml RESULTS virsh net-dumpxml test <network> <name>test</name> <uuid>2eff5e7f-847a-1fbf-ec82-01a46ef0f6c2</uuid> <forward mode='route'/> <bridge name='virbr3' stp='off' delay='0' /> <mac address='52:54:00:47:E6:15'/> <ip address='192.168.0.1' netmask='255.255.255.0'> </ip> </network ps aux | grep dns nobody 4391 0.0 0.0 21616 916 ?

[libvirt-users] How to use virt-install and http to install openbsd VM in KVM?
by Li, David 30 Nov '11

30 Nov '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

29 Nov '11

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 22 Nov '11

22 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 17 Nov '11

17 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 16 Nov '11

16 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 16 Nov '11

16 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 15 Nov '11

15 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

Hello, I have a few vms running on a blade server and i want to log the actual RAM and CPU utilization by these vms. dom.info(), libvirt API call is not giving correct results. It is always showing the max allocated resources. I have tried using virt-top also but same problem persists. Is there any thing that i am missing. -- Jatin Kumar

[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!
