[libvirt-users] LibVirt CPU problem
by Michael Beham 16 Jan '13

16 Jan '13

Hi, I´m testing to start a KVM-VM with different CPU settings and I get an weird error when I use the parameter: <cpu mode='host-model'> !! I have a AMD Opteron 4280 CPU, but in the VM, proc/cpuinfo shows me, that I´m using Intel core2duo cpu model T7700 and in the flag-line of proc/cpu the system is listing the svm-flag of AMD?!?! If I use <cpu mode='host-passthrough'> I get the right CPU-model listed in the VM! Anyone an idea why I get the wrong information with host-model? BTW some further information about used versions: LibVirt version is 0.9.12 qemu-kvm 1.0 Kernel 3.3.2 Cheers, Mike

[libvirt-users] Libvirt node is not getting booted through network
by Varun Bhatnagar 15 Jan '13

15 Jan '13

Hi, I am trying to boot my node through network with the following configuration: But I am getting an error message saying: Even my network setting is not getting reflected in the Virtualbox. Can anyone suggest me what is wrong with this configuration. I think to boot a node from network we need to define a boot server but where shall I add that, I am confused.... Any help will be appreciated. Thanks in advance.

[libvirt-users] A issue about KVM block migration
by 刘基 15 Jan '13

15 Jan '13

Hello everyone, I have a issue about the KVM block migration. Please give me some help. 1) I use the "virsh create" command to start a KVM VM in source machine. 2) And then, I use "virsh migrate" cammand to start a block migration: # virsh migrate --live --copy-storage-all --verbose win7 qemu+ssh:// 186.100.8.136/system root(a)186.100.8.136's password: Migration : [ 93% ] I execute "virsh list" command in source machine, and the result is: #virsh list Id Name State ----------------------------------------------------------- 1 win7 running I can find the corresponding qemu-kvm process in the result of "ps -ef | grep qemu-kvm" in source machine. And I execute "virsh list" command in destination machine, and the result is: #virsh list Id Name State ----------------------------------------------------------- 1 win7 paused 3) But after a few minutes，there have a error: # virsh migrate --live --copy-storage-all --verbose win7 qemu+ssh:// 186.100.8.136/system root(a)186.100.8.136's password: Migration : [ 97% ] error: Unable to read from monitor : Connection reset by peer. I execute "virsh list" command in source machine again, and the result is NULL. I cannot find the corresponding qemu-kvm process in the result of "ps -ef | grep qemu-kvm" in source machine. And I execute "virsh list" command in destination machine again, and the result is NULL. But, when I only use qemu-kvm command not use libvirt, I can test block migration successfully (use qemu-kvm to create a VM, and exec "migrate -b -d xxx" command in qemu-kvm monitor to migrate). The version of libvirt is 1.0.1 and the version of qemu-kvm is 1.2.0 ( 1.2.2 is also have this issue). Please give me some help. How to solve the issue. Thanks a lot. **

[libvirt-users] libvirt RPC error
by Parakkal, Navin S 11 Jan '13

11 Jan '13

Hi, I'm using qemu+ssh://username@hostname/system as the remote URI. Libvirt seems to be communicating fine until some 2 minutes (we poll every 5 seconds) and then it throws up RPC error and many counters are wrong. But if I collect on localhost the counters seems to be coming fine. Test and testvm are guests on the local machine where as Win8 and Ubuntu* are remote URI's connected through ssh. What causes this error "libvir: RPC error : End of file while reading data: : Input/output error" and how do we fix it ? I've pasted the logfile inline.

[libvirt-users] Attaching an "Internal Address"
by Varun Bhatnagar 10 Jan '13

10 Jan '13

Hi, I am trying to attach an internal address to my domain. So for that I am defining the following syntax in my xml file: but it is giving the following error: Tried giving interface type as network but that is adding Host-only type interface. Can anyone please suggest what can be the possible solution. I think it is some problem with the source network. Do I have to define any internal network before in any interface? If yes then how? Any help will be appreciated. Thanks in advance.

[libvirt-users] Unable to connect to vmchannel on host when the VM is started via libvirt
by Kaiwei Fan 10 Jan '13

10 Jan '13

Hi experts, When I start a VM using "virsh create vm.xml", I'm not able to connect to the vmchannel from host. The process libvirtd is running as root (modified qemu.conf to set user/group to root) already. The connect just hangs there even after the guest VM is up and running. However, if I start the VM using kvm directly (with same arguments as libvirtd in `ps auxwww`), the connect to vmchannel goes though after the guest VM is up and running. The problem is observed on ubuntu 12.10 (libvirt 0.9.13), but not ubuntu 12.04 (libvirt 0.9.8). Anyone knows why is this and how to fix it? Any suggestion is appreciated. ubuntu 12.10: Linux linux-01 3.5.0-17-generic #28-Ubuntu SMP Tue Oct 9 19:31:23 UTC 2012 x86_64 x86_64 x86_64 GNU/Linux ubuntu 12.04: Linux linux-06 3.2.0-30-generic #48-Ubuntu SMP Fri Aug 24 16:52:48 UTC 2012 x86_64 x86_64 x86_64 GNU/Linux Content of vm.xml: <domain type="kvm"> <uuid>c548c477-af6f-4aee-9e7d-987d6620aa27</uuid> <name>instance-00</name> <memory>262144</memory> <vcpu>1</vcpu> <os> <type>hvm</type> <boot dev="hd"/> </os> <features> <acpi/> </features> <clock offset="utc"> <timer name="pit" tickpolicy="delay"/> <timer name="rtc" tickpolicy="catchup"/> </clock> <devices> <disk type="file" device="disk"> <driver name="qemu" type="qcow2" cache="none"/> <source file="/home/user/project/kvm/instance-00/disk"/> <target bus="virtio" dev="vda"/> </disk> <serial type="file"> <source path="/home/user/project/kvm/instance-00/console.log"/> </serial> <serial type="pty"/> <channel type="unix"> <source path="/home/user/project/kvm/instance-00/vmchannel.sock" mode="bind"/> <target type="virtio" name="org.qemu.guest_agent.0"/> </channel> <graphics type="vnc" port="5900" autoport="no" keymap="en-us" listen="127.0.0.1"/> </devices> </domain>

09 Jan '13

Hi everyone: I am just a new user to libvirt. I installed libvirt as: ./configure make sudo make After that I run the program in the development guide. But it seems that the program is stuck in the function of virConnectOpenReadOnly. When I tried the command: virsh list --all, it is also stuck. So could anyone tell me what's wrong with this? Thank you so much Tianwei Zhang

[libvirt-users] Regarding the support of libvirt for shared memory
by achala joshi 04 Jan '13

04 Jan '13

Hello All, I want to use shared memory , but in virsh I am unable to provide the necessary options for use of shared memory. I want to have some scripts so that they can be included in the xml file so that each time the need is of shared memory , it can be directly used from there only. Thanks and Regards
