[libvirt-users] Setting the default Hypervisor
by RaSca 08 Mar '12

08 Mar '12

Hi all, I'm using libvirt with qemu-kvm and virtualbox on the same system. Everything is working, but I want to change the default uri fo virsh. At the moment, if i run: # virsh uri vbox:///system and because of this, if I try to list my vm(s) in this way: # virsh list --all Id Name State ---------------------------------- the output is empty. I need always to pass the uri: # virsh -c qemu:///system list --all Id Name State ---------------------------------- - ubuntu-vm shut off So, is there a way to set the default uri to be qemu:///system? I looked into /etc/default/libvirt-guests and /etc/default/libvirt-bin but I was not able to find an options (setting URIS= does not work). I'm on Debian Squeeze with backports. Thanks a lot, -- RaSca Mia Mamma Usa Linux: Niente è impossibile da capire, se lo spieghi bene! rasca(a)miamammausalinux.org http://www.miamammausalinux.org

[libvirt-users] where is the libvirt.xml ?
by suyi wang 08 Mar '12

08 Mar '12

Hi all: My OS is now Fedora16 , and the spice server is installed on it by rpms. Then I run 'qemu-kvm -hda /root/vaddsoft.img -m 512 -vga qxl -spice port=5930,disable-ticketing' , I want to find out where is the libvirt.xml for the command . Well , I mean that the libvirt.xml is genrated automatically, not by myself manually. Wish your help! Thanks a lot! -- Yours. suyi

[libvirt-users] tunneled VM migration error
by Shantanu Pavgi 08 Mar '12

08 Mar '12

I am getting following error with tunneled migration command: {{{ $ virsh --connect qemu:///system migrate --verbose --p2p --tunnelled 32 qemu+ssh://kvm-03/system error: operation failed: Failed to connect to remote libvirt URI qemu+ssh://kvm-03/system }}} However I am able to perform other virsh command like list, pool-list, dumpxml using the same remote libvirt URI: {{{ $ virsh --connect qemu+ssh://kvm-03/system list }}} Also, the hypervisor native migration is working fine with following command: {{{ $ virsh --connect qemu:///system migrate 31 qemu+ssh://kvm-03/system }}} I am confused why remote URI worked for some of the commands but not for the migrate command. Am I missing something with the tunneled migration command or libvirtd/qemu configuration file? Any help would be appreciated. Software versions on both systems: * CentOS 6.2 * Libvirt 0.9.4 * qemu-kvm 2:0.12.1.2-2.209.el6_2.4 -- Shantanu

[libvirt-users] Correctly using libvirt to mount /dev/pts and /dev in an lxc application container
by David Jablonski 08 Mar '12

08 Mar '12

We would like to mount /dev and /dev/pts correctly using the libvirt xml config file instead of doing a bind mount in a container init script we use. Currently the container config is: <domain type='lxc'> <name>CentOS_57</name> <uuid>ff5d3c04-49e6-a3cc-0a14-ff13625eca3c</uuid> <memory>262144</memory> <currentMemory>262144</currentMemory> <vcpu>1</vcpu> <os> <type arch='i686'>exe</type> <init>/bin/lxc-progs</init> </os> <clock offset='utc'/> <on_poweroff>destroy</on_poweroff> <on_reboot>restart</on_reboot> <on_crash>restart</on_crash> <devices> <emulator>/usr/libexec/libvirt_lxc</emulator> <filesystem type='mount' accessmode='passthrough'> <source dir='//home'/> <target dir='/home'/> </filesystem> <filesystem type='mount' accessmode='passthrough'> <source dir='/archive/centos57-root'/> <target dir='/'/> </filesystem> <filesystem type='mount' accessmode='passthrough'> <source dir='//archive'/> <target dir='/archive'/> </filesystem> <console type='pty'> <target type='serial' port='0'/> </console> </devices> </domain> The /bin/lxc-progs file is: #!/bin/sh service rsyslog start service sssd start service sshd start mount -t devtmpfs none /dev mount -t devpts none /dev/pts mount -t tmpfs none /dev/shm exec /bin/sh Basically how do we remove the above mount points in the lxc init process and use libvirt to control the mounts instead? Any help would be appreciated. Thank you. -- David W. Jablonski Systems Administrator INOC 608.204.0202 608.663.4555 djablonski(a)inoc.com www.inoc.com *** DELIVERING UPTIME ***
