Looks like your host is in fail not in maintenance, you can force it
with the below commands and later remove it.
step#1
On Engine machine:
$ su - postgres
$ psql -d engine
engine# update vds_dynamic set status=2 where vds_id in (select vds_id
from vds_static where vds_name LIKE '%THE_NODE_HOST_NAME%');
step#2
Go back to admin portal, your host will be in maint. and you should be
able to remove it.
Please keep the list in the reply for other people might help and
provide the logs from engine/vdsm.

oVirt hook to manage physical CPU pool, and automatically pin CPUs without overlap on the host
by David Jorm
Hi All
Thanks for the help that people have recently provided on this list.
I'm running into another edge case that, as far as I can see, does not
have a native solution within oVirt. I have a use case where every VM
must have 4 pinned vCPUs, and these must map 1:1 to physical CPUs so
that there are never two VMs contending for the same physical cores. I
already have code in place that ensures a VM will not be created or
started if n/4 VMs are already running on the target host, where n is
the number of physical cores. What I need now is to ensure that
pinning is managed so that each physical core maps 1:1 to vCPUs.
Would it be possible to manage the pool of physical cores in a local
DB, and implement a VDSM hook similar to the example on this page?
http://www.ovirt.org/VDSM-Hooks
Or would there be a preferable solution?
Thanks
David

Storage network clarification
by Fil Di Noto
I'm having trouble setting up a dedicated storage network.
I have a separate VLAN designated for storage, and configured separate
IP addresses for each host that correspond to that subnet. I have
tested this subnet extensively and it is working as expected.
Prior to adding the hosts, I configured a storage network and
configured the cluster to use that network for storage and not the
ovirtmgmt network. I was hopping that this would be recognized when
the hosts were added but it was not. I had to actually reconfigure the
storage VLAN interface via oVirt "manage host networks" just to bring
the host networks into compliance. The IP is configured directly on
the bond0.<vlanid>, not on a bridge interface which I assume is
correct since it is not a "VM" network.
In this setup I was not able to activate any of the hosts due to VDSM
gluster errors, I think it was because VDSM was trying to use the
hostname/IP of the ovirtmgmt network. I manually set up the peers
using "gluster peer probe" and I was able to activate the hosts but
they were not using the storage network (tcpdump). I also tried adding
DNS records for the storage network interfaces using different
hostnames but gluster seemed to still consider the ovirtmgmt interface
as the primary.
With the hosts active, I couldn't create/activate any volumes until I
changed the cluster network settings to use the ovirtmgmt network for
storage. I ended up abandoning the dedicated storage subnet for the
time being and I'm starting to wonder if running virtualization and
gluster on the same hosts is intended to work this way.
Assuming that it should work, what is the correct way to configure it?
I can't find any docs that go in detail about storage networks. Is
reverse DNS a factor? If I had a better understanding of what oVirt is
expecting to see that would be helpful.

Ok, thanks.
But keyUsage = critical,${ENV::OVIRT_KU}
extendedKeyUsage = ${ENV::OVIRT_EKU}
still looks strage.
Can you please check what you had before the migration?

memory leak in 3.5.6 - not vdsm
by Charles Kozler
Here is a screenshot of my three nodes and their increased memory usage
over 30 days. Note that node #2 had 1 single VM that had 4GB of RAM
assigned to it. I had since shut it down and saw no memory reclamation
occur. Further, I flushed page caches and inodes and ran 'sync'. I tried
everything but nothing brought the memory usage down. vdsm was low too
(couple hundred MB) and there was no qemu-kvm process running so I'm at a
loss
http://imgur.com/a/aFPcK
Please advise on what I can do to debug this. Note I have restarted node 2
(which is why you see the drop) to see if it raises in memory use over tim
even with no VM's running

[FC22] testing oVirt 3.6.2 : Hot plug memory not working
by wodel youchi
Hi,
I am using oVirt 3.6.2 on FC22 box, all-in-one installation, my purpose is
to test it.
I am using a simple Desktop :
- one cpu core i5 3550 with 4 cores
- 2x4 Go of RAM
I installed a Centos 6x64 VM with all updates + ovirt guest agent.
I tried to augment the memory from 1024 to 1536 (+512Mo) it didn't work I
had to shutdown the VM for the change to take effect.
Hot plug memory does it have something to do with the underneath hardware?
or does it depend on the guest OS?
or something else?
Regards.
