KVM live migration i/o error
Hi. I have three Ubuntu Server 14.04 trusty with KVM. Two of them are HP servers and one is Dell. Both brands run fine the KVM virtual servers, and I can do live migration between the HPs. But I get I/O errors in the vda when I migrate to or from the Dell server. I have shared storage with NFS, mounted the same way in all of them: nfs.sever:/kvm /var/lib/libvirt/images nfs auto,vers=3 I

KVM Live Migration
We have the following test environment: 2 x CentOS 5.5 KVM virtual hosts 2 x CentOS 5.5 network storage boxes with NFS shares on LVs on DRBD (primary/secondary, no HA, just replication). We have installed both CentOS and Win7 guests which live migrate almost instantly between hosts using Virt Manager (or virsh migrate). The problem is that the guests does not retain their running state after

Re: Libvirt Live Migration
I installed CentOS 7 which supported by default a newer version of qemu-kvm (qemu-kvm-1.5.3-60.el7.x86_64.rpm) but this time I got new error: << error: internal error: unable to execute QEMU command 'migrate': this feature or command is not currently supported >> but it's kind of wired because qemu-kvm-1.0 supported already live migration, so a newer version should also

image transfer incompletely in 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

Canceling a live migration via virsh? (QEMU/KVM)
I am using QEMU/KVM, using Live Migrations like this: virsh migrate --live ${name} qemu+ssh://${DESTINATION}/system My question, running this command makes it hang in the foreground. Is there a way for this to return immediately, so I can just poll for the migration status? Also, is there a way to _cancel_ a migration? I see the --timeout option, however if a given timeout is reached I would

Live Migration Without Shared Storage
I‘m very exited to hear that qemu has supported live migration without shared storage and I also have found some persons give their experiments, for example: (http://blog.allanglesit.com/2011/08/linux-kvm-management-live-migration-without-shared-storage/) # virsh migrate --live vmname qemu+ssh://kvmnode02.allanglesit.net/system --copy-storage-all --verbose --persistent --undefinesource I

Re: Libvirt Live Migration
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

live migration not working correctly
I have two servers running Ubuntu 9.10, with shared disk from ISCSI SAN and OCFS2, identical network configurations, shared ssh keys, and pki keys. My vm will boot from either machine and run correctly. When I attempt to do a live migration with "migrate --live base32 qemu +[ssh/tcp]://vm1/system" it initiates the vm on the other server, but leaves the vm on the current server in the

Live migration: Xen to KVM
Hello! Is there some way to migrate guest OS from one Xen-host to another KVM-host using libvirt?

KVM live migration issues for Windows guests
Hi, We're repeatedly facing a live migration issue with Windows guests, would be great if someone could send their thoughts/suggestions/experience on how to further troubleshoot this. When we live migrate a Windows instance, it gets migrated (guest is running on the destination host), but it eventually internally hangs. From the Windows logs, the operating system has tried to shut
