[libvirt-users] setvcpus
by Bhasker C V 04 Apr '12

04 Apr '12

Hi all, I am facing a bit of a trouble with setvcpus on a kvm libvirt The guest is crashing right after the command is given. I have no trouble with virtio_balloon and that is working fine when I use setmem command in virsh. The guest is running 3.3.1 kernel (the command fails both on the stock kernel 2.6.X as-well-as the latest 3.3.1) I have seen it working in xen. But this is kvm. Does this feature work with kvm ? Am I missing any kernel config which enables this ? thanks eg:- virsh # start fedora12 Domain fedora12 started virsh # vcpuinfo fedora12 VCPU: 0 CPU: 1 State: running CPU time: 7.3s CPU Affinity: yyyy VCPU: 1 CPU: 3 State: running CPU time: 2.3s CPU Affinity: yyyy virsh # vcpu fedora12 vcpucount vcpuinfo vcpupin virsh # vcpucount fedora12 maximum config 8 maximum live 8 current config 2 current live 2 virsh # list Id Name State ---------------------------------- 14 fedora12 running virsh # setvcpus fedora12 4 error: operation failed: could not change CPU online status virsh # list Id Name State ---------------------------------- virsh # virsh # version Compiled against library: libvir 0.9.1 Using library: libvir 0.9.1 Using API: QEMU 0.9.1 Running hypervisor: QEMU 0.14.1 -- Bhasker C V Secure Mails: http://pgp.mit.edu:11371/pks/lookup?op=get&search=0x4D05FEEC54E47413

[libvirt-users] Openvswitch support - port tagging
by Daniele Milani 03 Apr '12

03 Apr '12

I was looking at the release candidate of libvirt (0.9.11-rc2) and I have not been able to understand if the openvswitch support includes the port tagging support. So my question is: is it possible to create a tagged port? How? Otherwise, would it be useful to add this functionality? Thanks, Daniele Milani

Is this going to do what I think it will do? ie will the output be runable on a current licensed vmware server? qemu-img convert -f raw test.img -O vmdk test.vmdk

[libvirt-users] call for volunteer: FLOSS weekly podcast opportunity
by Eric Blake 03 Apr '12

03 Apr '12

The FLOSS weekly podcast is interested in doing an interview about libvirt development on June 6, at 9:30am Los Angeles time (UTC-7). For more information on past podcasts, see: http://twit.tv/show/floss-weekly With prodding from Justin Clift, I have volunteered to take on the task, but the show host, Randal, prefers to have two developers per show, so I'm looking for anyone else who has developed for or with libvirt, who would be interested in sharing the opportunity. You don't have to have a lot of commits under your belt, so much as having enough active interest in the project and what it enables you to do. In fact, having someone not directly tied to Red Hat as the second contact will probably provide a nicer balance to the interview. -- Eric Blake eblake(a)redhat.com +1-919-301-3266 Libvirt virtualization library http://libvirt.org

[libvirt-users] libvirt-lxc Cannot SSH into container
by Shweta Shinde 02 Apr '12

02 Apr '12

Hi, I am trying to run containers on rhel 6.2 using libvirt-lxc. I want to migrate my containers from sf.net lxc to libvirt-lxc. So, I am using the same root file system for libvirt-lxc, which I used for sf.netlxc. After starting the container, and getting console for it, I can see the boot log for the container, it shows all the services started successfully. I get ping reply from the IP assigned to this container, but cannot ssh into the container. After entering the password for ssh, connection closed error comes up. I tried chroot to the root filesystem, and checked sshd service status. It shows that sshd is stopped. Also the /proc of container is empty. Am I missing out something in configuration? This is my xml file for container <domain type='lxc'> <name>test01</name> <memory>332768</memory> <os> <type>exe</type> <init>/sbin/init</init> </os> <vcpu>1</vcpu> <clock offset='utc'/> <on_poweroff>destroy</on_poweroff> <on_reboot>restart</on_reboot> <on_crash>destroy</on_crash> <devices> <filesystem type='mount'> <source dir='/srv/lxc/test01'/> <target dir='/'/> </filesystem> <interface type='network'> <source network='default'/> </interface> <console type='pty' /> </devices> </domain> Thanks, Shweta

[libvirt-users] virsh create failed: cannot set CPU affinity on process 0
by 杨镭 30 Mar '12

30 Mar '12

Hello Everyone: We can't create vm on a physical server with 64 CPU(as reported by /proc/cpuinfo). The error message is: "cannot set CPU affinity on process 0" The following is the capabilities detected by libvirt: <arch>x86_64</arch> <model>Westmere</model> <vendor>Intel</vendor> <topology sockets='4' cores='10' threads='2'/> I wonder if libvirt uses incorrect CPU topology information to set process affinity which lead to the error above.
