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.
