[libvirt-users] Customize UNIX socket permissions
by Jonathan Lebon 04 Sep '13

04 Sep '13

Hi, I have a qemu domain which uses a virtio-serial port. On the host, the unix socket is created in /var/lib/libvirt/qemu. As non-root, I'd like to be able to communicate through this unix socket. The issue is that the socket is created as qemu:qemu with permissions 755 (does this come from libvirt's umask?). Is there any way to affect this permission from the domain's XML definition file? Even if it has to be created as qemu:qemu, having a permission of 775 would also be an acceptable solution. Thanks, Jonathan

[libvirt-users] Is virsh blockcommit supported? Thanks a lot

[libvirt-users] libvirt-qemu/kvm passthru w/Intel 82598EB
by laurence.schuler 04 Sep '13

04 Sep '13

Hi, I am trying to configure two identical systems with the following setup. dom0: Centos 6 OS on Apple Xserve i7 server with PCI cards for 4GB FC (LSI FC949ES) and 10GB Ethernet (Intel 82598EB) dom1: Centos 5 OS with passthru mode of PCI 4GB FC and 10GB Ethernet (ixgbe and mptfc blacklisted in dom0) Everything starts ok, but networking in dom1 using the 10GB interface has extremely high rtt w/ping tests (20-30ms avg). I've tried a few tweaks I've discovered via googling, but nothing seems to help. (run libvirt as root, set privilege mode, etc) For validation, I have the same card in Dell hosts running Centos 6 natively and they get an avg rtt of .06ms or better. Furthemore the Dell will contact the dom1 but the connection has rtt avg times of about 6ms. With the ethernet interface on the motherboard of the Apple Xserve, I will see rtt times of .06ms within the dom1's, so I think this points to a problem with the Intel card passthru usage, perhaps interrupts handling?. Does anyone know if I need to set any special options for the ixgbe driver under libvirt?

[libvirt-users] Running libvirt on a virtualized server
by Andre Gustavo Pereira da Silva 03 Sep '13

03 Sep '13

Hi everyone I'm trying to create a virtual machine using OpenNebula [1] on a centos 6.4 server, but i'm facing some erros using kvm / libvirt. This server is running on a virtual machine created on XCP. Then, my infrastructure is: XCP 1.6 (hypervisor - dom0) + CentOS 6.4 (running on a XCP VM) + OpenNebula 4.0.1 (installed on CentOS). In the host machine, I have the same infrastructure. The problem I'm facing is that, by following the tutorial [2], i've noticed that neither the parameter 'vmx' nor 'svm' is listed on the CPU information provided by the virtual machine where the centOs is running. However, if i run the same command in XCP hypervisor, the parameter 'vmx' is listed. That is, the CPU informations provided by XCP are different from those provided by its virtual machines. My question is: is it possible to use libvirt in this scenario? Here are some messages: - Libvirt log on centoOS (XCP VM): Aug 27 13:26:21 localhost libvirtd: 9945: info : libvirt version: 0.10.2, package: 18.el6_4.9 (CentOS BuildSystem <http://bugs.centos.org>, 2013-07-02-11:19:29, c6b8.bsys.dev.centos.org) Aug 27 13:26:21 localhost libvirtd: 9945: error : udevGetDMIData:1502 : Failed to get udev device for syspath '/sys/devices/virtual/dmi/id' or '/sys/class/dmi/id' Aug 27 13:26:21 localhost kernel: Ebtables v2.0 registered Aug 27 13:26:22 localhost kernel: lo: Disabled Privacy Extensions Aug 27 13:26:40 localhost polkitd[10145]: started daemon version 0.96 using authority implementation `local' version `0.96' Aug 27 13:28:35 localhost libvirtd: 9937: error : qemuProcessStart:3696 : unsupported configuration: Domain requires KVM, but it is not available.

Hi, I have an ESXi server, on top of it I have created one VM whose IP address is 192.168.79.1. I want to connect to the VM on ESXi server from my host machine but I am not able to do it. I have created a network "networkforSC" and I have pasted my xml file content below but I am not able to add any uplink (how to add it?) . Below is the xml file of my node as well as the network which I am creating on my ESXi server *<domain type='vmware'>* *<name>testNode</name>* *<uuid>50115e16-9bdc-49d7-f171-53c4d7f91710</uuid>* *<memory>1048576</memory>* *<currentMemory>1048576</currentMemory>* *<vcpu>1</vcpu>* *<console>/dev/console</console>* *<os>* *<type arch='x86_64'>hvm</type>* *</os>* *<devices>* *<disk type='file' device='disk'>* *<source file='[datastore1] testNode/testNode.vmdk'/>* *<target dev='sda' bus='scsi'/>* *<address type='drive' controller='0' bus='0' unit='0'/>* *</disk>* *<controller type='scsi' index='0' model='lsilogic'/>* ** *<interface type='bridge'>* *<mac address='00:50:56:25:48:c7'/>* *<source bridge='VM Network'/>* *</interface>* *<interface type='bridge'>* *<source bridge='test'/>* *</interface>* *</devices>* *</domain>* ########################################## Network File: *<network>* *<name>networkforSC</name>* *<portgroup name='test'>* *</portgroup>* *</network>* I have checked the network which got created on the server.

[libvirt-users] how to setup network filter
by Jiaan Zeng 02 Sep '13

02 Sep '13

Hi All, I am new to libvirt and encounter a strange problem to set up network filter in a NAT network. I launched VMs in a single host using NAT, i.e. interface type='network'. Now I want to control the outbound traffic from VM instance - only allow the VM to asses a set of ip addresses. My network filter xml is as follows. The problem is once I change the VM xml, shutdown and start VM, VM cannot get ip address. /var/log/libvirt/libvirt.log shows " error : virNetDevGetIndex:656 : Unable to get index for interface vnet2: No such device" error. But when I remove the drop rule in the filter xml, VM can get IP address. I even tried the clean-traffic filter shipped with libvirt. VM throws the same error above. Any idea why this happens? How can I implement outbound traffic control in libvirt? Thanks a lot. <filter name='filter-test'> <rule action='accept' direction='in' priority='500'> <tcp dstportstart='22'/> </rule> <rule action='accept' direction='out' priority='500'> <ip dstipaddr='IP1'/> </rule> <rule action='accept' direction='out' priority='500'> <ip dstipaddr='IP2'/> </rule> <rule action='drop' direction='out' priority='500'> <all/> </rule> </filter> The VM network section XML looks like this <interface type='network'> <mac address='52:54:00:0d:f1:ce'/> <source network='default'/> <filterref filter='filter-test'/> <address type='pci' domain='0x0000' bus='0x00' slot='0x03' function='0x0'/> </interface> -- Regards, Jiaan

[libvirt-users] Migration Clarification Request
by The PowerTool 31 Aug '13

31 Aug '13

I built a vm with the guest OS Windows XP. I have it running exactly the way I need it. Now I need to move it to a computer at another location. My plan was to build the vm and then just copy the ISO and take it to the new system. Specifications: Host OS is a current/up-to-date Fedora 18 I used yum install @virtualization I launched boxes in gnome and installed the guest system (XP) After getting everything running to my specifications I started researching how to move the vm to another system. I have one question: Referring to the information at: http://libvirt.org/migration.html " Migration of guests between hosts is a complicated problem" Can someone please point me to documentation stating why migration is "a complicated problem"?? The vm is powered off. I didn't use encryption (that I'm aware of--and I hope that doesn't bite me but I can re-install if necessary). gnome-boxes made this a pretty-simple setup and I like it. I know with about the same effort I can do this in VMWare, if necessary. I also know with VMWare I can create vm images that are portable and easily transported from system to system. If that is not the case with libvirt and gnome-boxes I'd like to understand why. Even though gnome-boxes made the setup fairly easy I can see where it is still in it's infancy. I thought libvirt was more mature and seems to offer CL access to everything I need (which I really like). Thanks, in-advance, for your help and consideration.

[libvirt-users] Finding out CPU topology
by Peeyush Gupta 29 Aug '13

29 Aug '13

Hi, I have been trying to find out CPU topology using libvirt. I understand that I can find out the number of cores/sockets/ threads etc through getCapabilities() function. What I am wondering is that is there any function that can provide me the exact topology like how many sockets, how many sockets per core and number of threads per core, if applicable or may be info about numa cells. Is there any mechanism to achieve this? Thanks, ~Peeyush Gupta

[libvirt-users] Defining VM with snapshots?
by Skardal, Harald 28 Aug '13

28 Aug '13

All, Using Centos 6.4 with provided libvirt: [root@node1 ~]# rpm -q libvirt libvirt-1.0.1-2.el6.x86_64 Assume a VM with one or more live snapshots. In virsh the VM snapshots can be listed. With virsh: - Stop and undefine this VM. - Then define (and start) this VM. The new VM does not have the list of snapshots. Is there a way with virsh to rebuild the metadata such that libvirt "knows" about the snapshots in the "disk stack"? Harald

[libvirt-users] Oracle RAC in libvirt+KVM environment
by Timon Wang 27 Aug '13

27 Aug '13

We wan't to setup two Oracle instance and make RAC work on them. Both VM are setup based on libvirt + KVM, we use a lvm lun which formated in qcow2 format and set the shareable properties in the disk driver like this: <disk type='block' device='disk'> <driver name='qemu' type='qcow2' cache='none'/> <source dev='/dev/81035c32-d2e4-4aaf-82fa-3e76ae587586/ca18f6a5-7c98-46ea-b562-9424e68a52f3'/> <target dev='hda' bus='ide'/> <shareable/> <address type='drive' controller='0' bus='0' target='0' unit='0'/> </disk> But when we use it as shared data disk like we use iscsi/FC disk for shared data disk, the disk can't be recognized as a share disk, and RAC can't be setup in the environment. Any body can give me some guild on this? I am wondering shareable in the libvirt config really makes the disk shareable? How can I setup the RAC environment in this situable? I found that vmware and vbox can do this according to a blog post, I am wondering if kvm has this ability to make a disk really shareable. -- Focus on: Server Vitualization, Network security,Scanner,NodeJS,JAVA,WWW Blog: http://www.nohouse.net

[libvirt-users] How to deal with LXC cgroup access control with apparmor ?
by 止语 27 Aug '13

27 Aug '13

I am playing with libvirt 1.1.1 (lxc) when I was starting a LXC container, the process location of cgroup is pretty , just the root directory from the process. But I could tune the cgroup in a container as an user that logged, This is not accepted... I wonder how to restrict it with apparmor ,so one can not modify files in the cgroup fs, e.g the cpus or mem, if i restrict it with "deny /sys/fs/cgroup/** wrklx," in apparmor ,the container woulld not start up . "Permission denied", because that a process would mount the cgroup, it seems done by libvirt_lxc, Any way to restrict the cgroup in the container or just not mount cgroup in the container ?? Any help would be appreciated, thanks .

[libvirt-users] Strange connectivity issues with bridged networking and masquerade
by Kolja Scheffler 25 Aug '13

25 Aug '13

Hi all, I'm currently in the process of building a 2-Node libvirt/KVM Cluster and ran into some issues regarding the network connectivity of our virtual machines. Our setup seemed to work fine, we were able to browse to Google and our own company website and some others from within the VM. Then we tried microsoft.com to download some Windows iso images from MS Partner Network. The page started to load, but only a few elements became visible - then it sticked to: "Loading data from microsoft.com" ...forever. A few other examples that do not work are: * www.opera.com * www.amazon.com * www.speedtest.net All of these pages load without any problem, when I access them from my laptop or even with Firefox via X-Forwarding launched directly on the hypervisor system. From within the VMs they just refuse to finish loading. The only thing those pages have in common, as far as I can see, is that they heavily utilize CDNs like Amazon Cloudfront or Akamai. The idea behind our setup is, that all virtual machines communicate on the 192.168.3.0/24 network. The nodes have a VLAN connection on eth1. To allow connections between VMs on different hosts, we created the bridge device br1 with eth1 attached and added the VMs to it. eth0 provides internet access with xx.xx.220.0 as additional public failover ip. We added 192.168.3.254 as additional IP to one of the node's br1 device to use it as the default gateway for the VMs. This IP can be migrated between the nodes. Our setup looks like this: ____________ / \ ( Internet ) \____________/ / \ Node1: | | Node2: | | xx.xx.217.8 (eth0) (eth0) xx.xx.217.10 xx.xx.220.0 \ {Masq.} / (eth1)----(eth1) | | 192.168.3.1 [br1 ] [br1 ] 192.168.3.2 192.168.3.254 | | | | 192.168.3.50 (vnet0) (vnet0) 192.168.3.75 ---------- iptables looks like this: root@vm01:~# iptables -S -P INPUT ACCEPT -P FORWARD ACCEPT -P OUTPUT ACCEPT -A FORWARD -d 192.168.3.0/24 -o br1 -m state --state RELATED,ESTABLISHED -j ACCEPT -A FORWARD -s 192.168.3.0/24 -i br1 -j ACCEPT -A FORWARD -i br1 -o br1 -j ACCEPT -A FORWARD -i eth0 -o eth0 -j ACCEPT root@vm01:~# iptables -S -t nat -P PREROUTING ACCEPT -P INPUT ACCEPT -P OUTPUT ACCEPT -P POSTROUTING ACCEPT -A POSTROUTING -s 192.168.3.0/24 ! -d 192.168.3.0/24 -j MASQUERADE -A POSTROUTING ! -s 192.168.3.0/24 -d 192.168.3.0/24 -j MASQUERADE --------- Some additional information that might be helpful: root@vm01:~# virsh version Compiled against library: libvir 0.9.12 Using library: libvir 0.9.12 Using API: QEMU 0.9.12 Running hypervisor: QEMU 1.1.2 --------- root@vm01:~# uname -a Linux vm01.cluster 3.2.0-4-amd64 #1 SMP Debian 3.2.46-1 x86_64 GNU/Linux --------- I don't know if it's really libvirt-related but perhaps someone here has an idea what to try. Any advice on this is really appreciated, as I am at my wits' end. Thank you in advance... :) Kind regards Kolja Scheffler

[libvirt-users] Information needed regarding the libvirt version libvirt-1.0.6-1
by arun abhinay 23 Aug '13

23 Aug '13

Hi, We have upgraded the libvirt version from libvirt-1.0.5 to libvirt-1.0.6-1 on our linux machine. After this upgrade "virsh cpu-stats <domain>" command is not working on our HardWare. *virsh # cpu-stats test error: Failed to retrieve CPU statistics for domain 'test' error: internal error error accessing cgroup cpuacct for vcpu* ** *# cat /proc/cgroups #subsys_name hierarchy num_cgroups enabled cpuset 3 4 1 ns 0 1 1 cpu 1 6 1 cpuacct 7 3 1 memory 2 3 1 freezer 0 1 1 net_cls 0 1 1 blkio 0 1 1 * *# chkconfig --list | grep cg cgroups_mount 0:off 1:on 2:on 3:on 4:on 5:on 6:off* We have also found that there is no "cgroup" directory created by kenel under "/sys/fs/". We suspect that the 'cgroup' controllers are not mounted properly and hence the issue is observed. While using the libvirt-1.0.5 version below mentioned mount commands were sufficient to mount cgroup controllers *mkdir -p /dev/cgroup_cpuacct mount -t cgroup -o cpuacct cpuacct /dev/cgroup_cpuacct* As cgroups hieracrhy inside libvirtd has changed in libvirt-1.0.6-1, we feel that the above commands are now not sufficient. We feel we have to do some more steps get the 'cgroups' mounted properly on our hardware. Since we are new to libvirt and can you please help us by providing some pointers to fix the above issue and get cpu-stats working on our HardWare. Since we have to fix this on top priority, can you please reply as soon as possible. Please let us know if you need any further information from our side. Thanks in advance. BR Abhinay
