Hi, I'm having a hard time to figure how to perform Xen live migration using the python API with the same rate of success than virt-manager. # virsh version Compiled against library: libvir 0.8.3 Using library: libvir 0.8.3 Using API: Xen 3.0.1 Running hypervisor: Xen 3.2.0 The goal is to have the migration done in only one call, including a definition in the remote xend and undefinition

Hello I have a question about live migration when libvirt requires sasl authentication. I have managed to configure remote access for user nova with sasl enabled (credentials stored in auth.conf - https://review.openstack.org/#/c/12706/). It looks like live migration do not use these credentials at all. What is more it thinks that sasl is not not configured: 2013-07-01 09:49:09.317+0000: 17997:

Hi, I am running libvirt 0.8.6 on qemu (kvm, really) 0.12.5. I have noticed that while a live migration is running, I cannot do anything else with libvirt -- even 'virsh list' blocks without output until the migration is almost done. (At that point 'virsh list' will dump a final screen showing the VM I just migrated as 'running'; the next run of 'virsh

Hello I am working with 3 host machines each running xen with shared NFS storage. I am working on automatic load balancing if one host is over utilized and another is under utilized by measuring the utilization from xentop. I am facing a problem after migration of VM. I am setting the flags ( 1| 8| 16) in order to do live migration, persist VM on destination, undefine host from source. After

Hi, We've run into a problem with libvirt 1.1.2 and are looking for some comments on whether this is a bug or design intent. We're trying to use migrateToURI() but we're using a few things (numatune, vcpu mask, etc.) that may need adjustment during the migration. We found that migrateToURI2() mostly works if we use XML created by copying the domain XML from the running instance

Hi Martin, in the meantime, I've found a solution which I consider at least acceptable: 1. create zfs snapshot of domain disk (/dev/zstore/test-volume) 2. save original XML domain definition 3. create snapshot in libvirt like this: virsh snapshot-create --xmlfile snap.xml --disk-only --no-metadata test-domain snap.xml: <domainsnapshot> <disks> <disk

Yes. Since the 0.9.7 release, the configuration XML is transferred to the other side too. However, by default, migrated domains are

Team, I'm trying to migrate a domain offline(shutdown mode) using libvirt-python API 'migrateToURI' but it gives me an error : libvirt: QEMU Driver error : Requested operation is not valid: domain is not running When I tried the same API for live migration(running and suspend mode), it gives me an error: libvirt: QEMU Driver error : Unsafe migration: Migration may lead to data

Hi, Thanks for infos. My concern is the following : In order to establish datas exchanges between hosts and guest , I'll add a channel device to a running Guest ( as I learned from you that it's possible to do that without stopping the Guest). When the guest migrates to another host , this one must be able to retrieve the channel device parameters to be able to dialog with the

Hi My libvirt version is 3.4.0, I migrate guest between two host, The two host have same hostname( hostname cmd output same), I try find solution on Internet, I find someone say host uuid same, But virsh sysinfo output uuid is different, when I change one host's hostname, migrate success. I wish know why, and Can I solution this problem not change hostname. My program use api

Hi, Is a change , by edit it via virsh edit , in the "local" .xml configuration file (i.e. adding a channel device) persistent when live migrating the guest on another host ? Thx. J.P.

Hi all, I'm using ZFS on Linux block volumes as my VM storage and want to do live migrations between hypervisors. If I create ZFS snapshot of used volume on source host, send it do destination host (zfs send/recv) and then run live migration with VIR_MIGRATE_NON_SHARED_DISK flag, the migration works OK. But this procedure copies the whole disk twice which is a huge downside. The best
