[ovirt-users] Two Problems On New Install

[Charles Tassell]

Hi Everyone,

   I recently installed oVirt 4.0 on two servers with an iSCSI 
backstore, and I'm having two issues I'm having trouble tracking down.  
First, the initial datastore that the hosted engine is running on won't 
connect.  It just says "Unattached" in the GUI, and I can't find an 
error message anywhere.  Not a huge deal, it just means I can't see the 
hosted engine itself in the GUI.

   More importantly: I can't migrate VMs.  They fail with errors like 
this in the vdsm.log of the destination host:

Thread-60381::ERROR::2017-02-14 
21:55:47,921::vm::767::virt.vm::(_startUnderlyingVm) 
vmId=`59f235cc-3ab2-4dae-b460-62be850e3d5d`::Failed to start a migration 
destination vm
Traceback (most recent call last):
   File "/usr/share/vdsm/virt/vm.py", line 733, in _startUnderlyingVm
     self._completeIncomingMigration()
   File "/usr/share/vdsm/virt/vm.py", line 3113, in 
_completeIncomingMigration
     self._incomingMigrationFinished.isSet(), usedTimeout)
   File "/usr/share/vdsm/virt/vm.py", line 3196, in 
_attachLibvirtDomainAfterMigration
     raise MigrationError(e.get_error_message())
MigrationError: Domain not found: no domain with matching uuid 
'59f235cc-3ab2-4dae-b460-62be850e3d5d'

   If I shut the VM down and start it on the host it works fine, it just 
won't migrate.  I notice I'm also seeing a lot (like every 7 seconds) of 
this error:

JsonRpc (StompReactor)::ERROR::2017-02-14 
21:57:33,984::betterAsyncore::113::vds.dispatcher::(recv) SSL error 
during reading data: unexpected eof

   Which I can't seem to diagnose.  Any ideas?
