VM migration upon shutdown in centos 7
Hi, I have CentOS 7, two node system which allows live VM migration between them. Live migration triggered from virsh is happily happening. I am using GlusterFS for replicating VM disk files. Now I want to automatically do the live migration at the time of reboot/shutdown/halt of the host node and for this I have written a systemd service unit [vPreShutdownHook.service] and placed the live

Clarification about virsh migration options
I am trying to work out what all the options are for migrating a KVM machine to another KVM machine, without using shared storage. The documentation is not quite verbose and not intuitive, so I'm hoping someone can explain this to me. The man pages show this syntax: migrate optional --live --p2p --direct --tunnelled --persistent --undefinesource --suspend --copy-storage-all --copy-storage-inc

virsh migrate --copy-storage-inc
Hello, I use libvirt on machines without shared storage. My VM's have all one qcow2-disk, with the same name as the VM. When I want to migrate a VM, I check if there is an qcow2 image on the other host with that name. When that's not the case, I copy the image using rsync first. If the image excist, I don't do that, and I think that "--copy-storage-inc" will do it. But I

Libvirt newbie, need help with doubts
Hi, These are my doubts: 1. I tried live migration of Ubuntu 11.04 from the one physical machine to another using the migrate() function. I connected via tcp in the destination URI and migrated successfully(lesser than 2 seconds). I tried running virsh list --all on the destination PM and confirmed that the VM had been migrated successfully. When I tried checking ps aux | grep vmname where

Should domain be undefined after migration, or not?
I have been running a lab using libvirt under Debian Wheezy (libvirt 0.9.12.3-1, qemu-kvm 1.1.2+dfsg-6, virt-manager 0.9.1-4). There are a number of machines as front-end servers and an nbd shared storage backend. When I live-migrate a domain from one machine to another, normally I observe that afterwards the domain remains on the source host (but in "shutdown" state), as well as on

couple of ceph/rbd questions
Hi, I've recently been working on setting up a set of libvirt compute nodes that will be using a ceph rbd pool for storing vm disk image files. I've got a couple of issues I've run into. First, per the standard ceph documentation examples [1], the way to add a disk is to create a block in the VM definition XML that looks something like this: <disk type='network'

migrate local storage to ceph | exchanging the storage system

Hi, after years of beeing pleased with local storage and migrating the complete storage from one host to another, it was time for ceph.

unable to execute QEMU command 'migrate': this feature or command is not currently supported
Hi all 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

couple of questions
Hey folks, I've been experimenting with native NBD live migration w/ TLS and have a couple of questions. 1) It appears that in some cases modified default_tls_x509_cert_dir from qemu.conf is not respected, seems like virsh always expects a default location and does not check default_tls_x509_cert_dir: virsh # migrate vm1 qemu+tls://ratchet.lan/system --live --persistent --undefinesource

Support live migration of OpenVZ container
Hi libvirt team, I was trying to migrate an OpenVZ domain from one host to another host. It seems that the live migration of OpenVZ container is there ( https://openvz.org/Migration_from_one_HN_to_another), but it haven't been integrated to libvirt yet. In particular, I ran the following commands and it failed: $ sudo virsh migrate --live --verbose --undefinesource 101 openvz+ssh://
