Hi all,
I have had a strange behavior yesterday on a new cluster.
A Windows 2008 Guest suddenly was off, but I could not find any clue in
the logs on why it was off.
It's a VM which was migrated from a physical one in the w.e. It had been
working fine for the whole time.
I then thought it had something to do with the file system (as it's on
gluster), but no clue there either, no errors were reported at that time.
The server is also a gluster server and has a dedicated bond for
gluster, a dedicated bond for cluster, and a dedicated bond for the LAN,
all with balance-alb.
The ethernet for cluster and gluster have jumbo frames enabled (enabled
also on the switches)
it's a dual E5-2630 server with 128GB ram, and it's not over allocated,
server load is basically very low.
The vm has many cpu assigned but is not using much of them right now.
down happened around 16:20 (local time)

I have checked basically all the logs but found no clues on what happened.
Also within windows the event viewer does not report anything except
that at next boot (which I had to start manually),
it reported that windows was badly shutdown.
Virtio disk driver installed is 0.1.126
The VM is NOT configured for HA, and right now it's the only vm which is
heavily used, the other VMs are not much used but they did not stop,
they all use the same glusterfs filesystem.
this is the VM configuration:
boot: cdn
bootdisk: virtio0
cores: 8
ide2: none,media=cdrom
memory: 65536
name: scavb
net0: e1000=1C:C1:DE:E9:2A:06,bridge=vmbr0
numa: 0
onboot: 1
ostype: win7
scsihw: virtio-scsi-pci
smbios1: uuid=90477e47-4357-42f8-9c1d-797d4111a604
sockets: 2
virtio0: datastore1:101/vm-101-disk-1.qcow2,size=500G
virtio1: datastore1:101/vm-101-disk-2.qcow2,size=900G
Any hint on how to proceed.
If any other info is needed for debug please let me know.
