[ovirt-users] ovirt node connection fails

[Bill James]

After rebooting a hardware node it can no longer connect in ovirt.

I can run this and it works fine:
[root at ovirt test host-deploy]# HOST="10.176.30.97"; ssh -i 
/etc/pki/ovirt-engine/keys/engine_id_rsa "$HOST"  'umask 0077;echo 
$OVIRT_TMPDIR; MYTMP="$(TMPDIR="${OVIRT_TMPDIR}" mktemp -d -t 
ovirt-XXXXXXXXXX)"; echo MYTMP=$MYTMP; trap "chmod -R u+rwX \"${MYTMP}\"" 0
 > '

MYTMP=/tmp/ovirt-IhxDxcDd8y
[root at ovirt test host-deploy]# echo $?
0

When I add the tar part it just waits forever.



Only change I made before reboot was uncommenting 'user = "root"' in 
/etc/libvirt/qemu.conf so that import-to-ovirt.pl would work.
Another host had same issue. I tried putting in maintenance and 
reinstalling and removing; re-adding. Didn't help.
Finally just re-kickstarted the host and that one works fine now, 
complete with the qemu.conf change.
Attached are the engine.log, vdsm.log and supervdsm.log.

I have done some modifications trying to get vdsm hook to work (see 
"multiple NICs VLAN ID conflict" thread), but I don't think that is 
related, especially since rekickstarting one host fixed it.

ovirt-engine-3.6.3.4-1.el7.centos.noarch

Thanks!
