Valentin, Please check if the VM guest has vm-tools installed else the “virsh migrate --live” parameter requirement is not fulfilled else you has to turn off the VM guest and do the offline “virsh migrate” without “--live” options. Hope that helps. Xlord From: CentOS-virt [mailto:centos-virt-bounces@xxxxxxxxxx] On Behalf Of Sandro Bonazzola

I'm trying to do a live migration with non-shared storage on CentOS 7. It was working
well doing it from CentOS 6 to CentOS 7 but not between to CentOS 7 machines. I read
that this feature was removed in RHEL/CentOS 7 but should be available in the CentOS-QEMU-EV
repository. But I still get the error using qemu-kvm-ev:
error: internal error: unable to execute QEMU command 'migrate': this feature or command is not currently supported
My installed libvirt and qemu packets are:

My command is:
virsh migrate --live --copy-storage-all --persistent --undefinesource --tunnelled --p2p --verbose --xml server.xml server qemu+ssh://xxx@a.b.c.d/system
Any help would be greatly appreciated.
Thanks, Valentin
