Hi guys,
I am new to QEMU-KVM, libvmi and libvirt stuff.
Libvmi uses libvirt.
I am trying to to run process-list example of libvmi and getting error as
below. It seems that this error may be due to libvirt as it is not able to
find domain.
I seek your kind help on below error:
spanhal1@seclab2:~/KVMModule/libvmi-0.10.1$ sudo ./examples/process-list
ubuntu
libvir: QEMU error : Domain not found: no domain with matching name 'ubuntu'
VMI_ERROR: Failed to get domain id from name.
Failed to init LibVMI library.1
Here are few details of step I performed:
1. I have installed KVM module. (version 3.5)
2. Installed QEMU-KVM. (version 1.2.0)
3. Installed libvirt(version 0.1.2.5)
4. Installed libvirt-bin(version 0.9.8-2ubuntu17.19)
5. Installed libvmi. (version 0.10.1)
6. Then I am trying to run process-list example and I am getting error as
above.
sudo ./examples/process-list ubuntu
To deal with this, I tried creating VM with domain name ubuntu using steps
given at below link.
https://help.ubuntu.com/community/KVM/CreateGuests
http://virt-tools.org/learning/install-with-command-line/
Create VM:
$sudo apt-get install virtinst
$sudo fallocate -l 8192M /var/lib/libvirt/images/guest.img
$sudo qemu-img create -f qcow2 /var/lib/libvirt/images/guest.qcow2 8192
spanhal1@seclab2:~/KVMModule$ sudo virt-install --connect qemu:///system -n
ubuntu -r 512 -f guest.qcow2 -s 12 -c
/home/spanhal1/KVMModule/ubuntu-12.04.4-desktop-amd64.iso --vnc
--noautoconsole --os-type linux --accelerate --network=network:default
ERROR Host does not support any virtualization options
Here are few workaround and information for this error:
1. spanhal1@seclab2:~/KVMModule$ modprobe kvm
spanhal1@seclab2:~/KVMModule$ lsmod | grep kvm
kvm_intel 137888 0
kvm 422160 1 kvm_intel
2. spanhal1@seclab2:~/KVMModule$ kvm-ok
INFO: /dev/kvm exists
KVM acceleration can be used
Check if virutalization is enabled by BIOS:
spanhal1@seclab2:/var/log/libvirt$ sudo modprobe msr
spanhal1@seclab2:/var/log/libvirt$ sudo rdmsr 0x3a
5
(Values 3 and 5 mean it's activated).
