libvirt users - Jan 2017 - 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 down during the live migration.

  

There is no info at all, even at debug level, in libvirt logs.

I'm thinking to go with perf kvm or maybe kernel upgrade, but it might be
I'm
missing something obvious in Windows for this scenario?

  

QEMU 2.0.0  
Libvirtd 1.2.2  
Host kernel version : 3.13.0-40-generic  
Windows version: Windows 2012 R2  

Has RBD volumes attached driver name='qemu' type='raw'
cache='writeback'/, but
reproduced also without.

  

Thanks!
