similar to: Get information during live migration

Hi all, I am using libvirt version 0.10.1 and qemu-kvm version 1.2.0 with RHEL 6.3 When I use libvirt API to make block migrate with a VM, it failed frequently. I check the migrated VM and found that the filesystem damaged. But sometimes it works very fine, I don't know why, it seems to be random. All failed tests have the same condition, image transfer incompletely in live migration. The

Hi, We have the following environment for live-migration with non-shared stroage between two nodes, Host OS: RHEL 6.3 Kernel: 2.6.32-279.el6.x86_64 Qemu-kvm: 1.2.0 libvirt: 0.10.1 and use "virsh" to do the job as virsh -c 'qemu:///system' migrate --live --persistent --copy-storage-all <guest-name> qemu+ssh://<target-node>/system The

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

Thanks for your answer, 1) In this case i'm not using shared storage, the migration is happening between two non-shared storage with full disk copy 2) I already created the file with same size, and the vm works properly after a restart, my problem that it remains paused and I can't resume it until it's rebooted. 3) I'm using qemu-kvm 1.0 On 24 November 2014 at 10:22, Michal

I'm trying to implement a virtualization API. I was testing migration with libvirt I got some problems. When I use the following command : *virsh migrate --live --persistent --copy-storage-all vm-clone1 qemu+ssh://server_ip/system* the migration works fine but in the destination host the migrated vm is paused and I can't unpause it and I need to reboot the vm to be able use it in the

Hi, I hope someone can help me out. I'm running into an issue with libvirt 1.2.12 reporting "operation failed: domain is no longer running" for a migration when qemu thinks it was fine. The steps are: 1) create guest with stress test running in it to dirty memory at a high rate (fast enough that it would not normally complete live-migration) 2) trigger live migration with

Hola. Just tried a live migration after fixing the pc-q35-2.1 error. Now i have new problem. It seems during live migration only the ram gets migrated. I use the following command. # virsh migrate --live domain qemu+ssh://newhost/system --copy-storage-all --verbose --persistent It works without problems. Apart from beeing way to fast. # virsh migrate --live domain qemu+ssh://newhost/system

Thanks Eric. So, I need to look at QEMU. Do you know which files/functions should I look at? ​-- Faiz​ On Thu, Mar 20, 2014 at 12:41 PM, Eric Blake <eblake@redhat.com> wrote: > On 03/20/2014 10:05 AM, Faizul Bari wrote: > > ​Hello, > > > > I have been trying to track different phases of a live migration > process.
