[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 07 Mar '12

07 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 07 Mar '12

07 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 ***

[libvirt-users] libvirt for spice

Hi all: I tried kvm on my ubuntu with the libvirt.xml file as follows: <domain type='kvm'> <name>instance-00000011</name> <memory>2097152</memory> <os> <type>hvm</type> <boot dev="hd" /> </os> <features> <acpi/> </features> <vcpu>1</vcpu> <devices> <sound model='ac97'/> <input type='tablet' bus='usb'/> <disk type='file'> <driver type='qcow2'/> <source file='/opt/stack/nova/nova/../ /instances/instance-00000011/disk'/> <target dev='vda' bus='ide'/> </disk> <disk type='file'> <driver type='qcow2'/> <source - Ignored: file='/opt/stack/nova/nova/..//instances/instance-00000011/disk.local'/> <target dev='vdb' bus='ide'/> </disk> <interface type='bridge'> <source bridge='br100'/> <mac address='02:16:3e:44:a1:dd'/> <filterref filter="nova-instance-instance-00000011-02163e44a1dd"> <parameter name="IP" value="10.0.0.2" /> <parameter name="DHCPSERVER" value="10.0.0.1" /> </filterref> </interface>  <serial type="file"> <source path='/opt/stack/nova/nova/..//instances/instance-00000011/console.log'/> <target port='1'/> </serial> <console type='pty' tty='/dev/pts/2'> <source path='/dev/pts/2'/> <target port='0'/> </console> <serial type='pty'> <source path='/dev/pts/2'/> <target port='0'/> </serial> <graphics type='vnc' port='-1' autoport='yes' keymap='en-us' listen='0.0.0.0'/> </devices> </domain> So it works well. Howerver, I want change the remote access method by spice, I simply changed the libvirt.xml as follows: <domain type='kvm'> <name>instance-00000011</name> <memory>2097152</memory> <os> <type>hvm</type> <boot dev="hd" /> </os> <features> <acpi/> </features> <vcpu>1</vcpu> <devices> <sound model='ac97'/> <input type='tablet' bus='usb'/> <disk type='file'> <driver type='qcow2'/> <source file='/opt/stack/nova/nova/..//instances/instance-00000011/disk'/> <target dev='vda' bus='ide'/> </disk> <disk type='file'> <driver type='qcow2'/> <source file='/opt/stack/nova/nova/..//instances/instance-00000011/disk.local'/> <target dev='vdb' bus='ide'/> </disk> <interface type='bridge'> <source bridge='br100'/> <mac address='02:16:3e:44:a1:dd'/> <filterref filter="nova-instance-instance-00000011-02163e44a1dd"> <parameter name="IP" value="10.0.0.2" /> <parameter name="DHCPSERVER" value="10.0.0.1" /> </filterref> </interface>  <serial type="file"> <source path='/opt/stack/nova/nova/..//instances/instance-00000011/console.log'/> <target port='1'/> </serial> <console type='pty' tty='/dev/pts/2'> <source path='/dev/pts/2'/> <target port='0'/> </console> <serial type='pty'> <source path='/dev/pts/2'/> <target port='0'/> </serial> <graphics type='spice' port='-1' autoport='yes' keymap='en-us' listen='0.0.0.0'/> </devices> </domain> As you can see, I just change <graphics type='vnc' port='-1' autoport='yes' keymap='en-us' listen='0.0.0.0'/> to <graphics type='spice' port='-1' autoport='yes' keymap='en-us' listen='0.0.0.0'/> , But it called the error as follows: libvirtError: internal error Process exited while reading console log output: char device redirected to /dev/pts/12 TRACE: do_spice_init: starting 0.8.1 TRACE: do_spice_init: statistics shm_open failed, Permission denied" I wish someone can give me some help!

I have a rhel6.0 server running kvm. I have recently needed to add additional cpu's to some of the guests but cannot do it via virt-manager, can't doit using virt, and can't do it by vi the guest.xml file. Is this a bug or am I missing something? Thanks, DaveB
