Re: [libvirt-users] Live Migration Issue

Sorry, ctrl entered. I’m hoping someone here can help me figure out what’s going on here. I’ve got two CentOS 7 hosts with shared storage that I’m trying to do live migrations between and I’m running into an error with VMs that were originally created on a CentOS 6 host and then moved the CentOS 7 hosts. The CentOS 6 VM runs fine on the host, and can do non-live migrations without any issues, however when attempting to live migrate the VM it fails. The VM itself is CentOS 7. Live migration does work when using VMs created using CentOS 7. Error message: “libvirtd virKeepAliveTimerInternal connection closed due to keep alive timeout. Cannot acquire state change lock (held by remoteDispatchDomainMigratePrepare3params)” Surrounding error messages here: Origin Host: https://pastebin.com/fLN6DRiq Recipient Host: https://pastebin.com/xR6mnaW2 The command being run is: Virsh --connect qemu:///system migrate --live vmname qemu+SSH://host2/system Firewall is turned off, SELinux is turned off, CentOS 7 CPUs are identical, both hosts fully updated. I’ve tried: Converting the VM from QCOW2 to Raw Converting the VM from QCOW2 to QCOW2 to try to get it to regenerate the XML/inject CentOS 7 Drivers Installed new drivers Updated all the packages in the VM. Removed all the Devices from the VM, except the HDDs.
