After rebooting a hardware node it can no longer connect in ovirt. 2016-03-17 23:02:46,547 ERROR [org.ovirt.engine.core.uutils.ssh.SSHDialog] (org.ovirt.thread.pool-8-thread-9) [7389eed3] SSH error running command root@10.176.3 0.97:'umask 0077; MYTMP="$(TMPDIR="${OVIRT_TMPDIR}" mktemp -d -t ovirt-XXXXXXXXXX)"; trap "chmod -R u+rwX \"${MYTMP}\" > /dev/null 2>&1; rm -fr \"${MYTMP}\" > / dev/null 2>&1" 0; tar --warning=no-timestamp -C "${MYTMP}" -x && "${MYTMP}"/ovirt-host-deploy DIALOG/dialect=str:machine DIALOG/customization=bool:True': Command returned failure code 1 during SSH session 'root@10.176.30.97' 2016-03-17 23:02:46,547 ERROR [org.ovirt.engine.core.uutils.ssh.SSHDialog] (org.ovirt.thread.pool-8-thread-9) [7389eed3] Exception: java.io.IOException: Command returned failure code 1 during SSH session 'root@10.176.30.97' at org.ovirt.engine.core.uutils.ssh.SSHClient.executeCommand(SSHClient.java:527) [uutils.jar:] I can run this and it works fine: [root@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@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!
