[Qemu-devel] [Bug 1450891] Re: VM will not resume on GlusterFS

[Christopher Pereira]

Hi Kevin,

I understand. In this case (where the gluster process was killed or
crashed) I guess the best option would be to poweroff and restart the
VM, which can be done client-side (ovirt + libvirt)

Please mark as "Won't fix".

Thanks.

Title:
  VM will not resume on GlusterFS

Status in QEMU:
  New

Bug description:
  oVirt uses libvirt to run QEMU.
  Images are passed to QEMU as files, not file descriptors.
  When running images from a GlusterFS, the file descriptors may get 
invalidated because of network problems or the glusterfs process being 
restarted.
  In this case, the VM goes into paused state.
  When trying to resume the VM ('cont' command), QEMU uses the same invalidated 
file descriptors throwing a:
  "block I/O error in device 'drive-virtio-disk0': Transport endpoint is not 
connected (107)".

  Please check file-descriptors and reopen image file on 'cont' event in QEMU.
  Thanks.
