## Live Migration not working
|
|
|
|
Error message: "ERROR nova.virt.libvirt.driver [...] Live Migration failure: internal error: unable to execute QEMU command 'migrate': this feature or command is not currently supported"
|
|
|
|
|
|
|
|
Solution:
|
|
|
|
|
|
|
|
Install qemu* from oVirt repositories:
|
|
|
|
1. yum install http://resources.ovirt.org/pub/yum-repo/ovirt-release35.rpm
|
|
|
|
2. yum update
|
|
|
|
|
|
|
|
The yum update will replace the packages qemu-img qemu-kvm qemu-kvm-common with the newer versions qemu-kvm-common-ev qemu-img-ev qemu-kvm-ev
