Ovirt Node NG (4.2.3.1-0.20180530) Boot fail ISCSI using ibft after installation
by Ralf Schenk
Hello,
I successfully installed Ovirt Node NG from ISO to an ISCSI target
attached via first network interface by using following extensions to
the grub cmdline:
"rd.iscsi.ibft=1 ip=ibft ip=eno2:dhcp"
I want to use the server as diskless ovirt-node-ng Server.
After successful install the system reboots and starts up but it fails
later in dracut even having detected correctly the disk and all the LV's.
I think "iscsistart" is run multiple times even after already being
logged in to the ISCSI-Target and that fails finally like that:
*[ 147.644872] localhost dracut-initqueue[1075]: iscsistart: initiator
reported error (15 - session exists)*
[ 147.645588] localhost dracut-initqueue[1075]: iscsistart: Logging

HostedEngine and affinity groups
by tehnic＠take3.ro
Hi,
i operate a 3 node ovirt42 cluster (hyperconverged).
Now i would like to isolate the HostedEngine from the other VMs.
The reason is to minimize the impact of outage of one of the nodes.
When the node with the HE is away there is no impact at all on the running VMs.
If one of the other nodes goes down, then i have still a running HE which restarts
the missing VMs on remaining nodes fast again.
I cannot use hard affinity because in case of failure i need all resources of the 2 remaining modes,
so i configured a soft negative affinity group for every VM between this VM and the HE.
As a first test i migrated the HE to a node with VMs but even after a while nothing happened.
I would have expected that either the HE or the VMs on this node would have been migrated to
fullfill the soft negative affinity.
Now my questions:
Are my thoughts correct?
Is there a better solution than making one (soft negative) affinity group for every VM to isolate from HE?
Does the affinity group enforcement engine work at all with soft rules?
Regards,
Robert

VM can't start: Unknown CPU-Model
by Tobias Scheinert
Hi,
we see here a confusing problem. A college reboots/shutdown his VMs for
maintenance. After that he starts the VMs (~20), but one of them throws
following error:
> VM <name> is down with error. Exit message: internal error: Unknown CPU-Model SandyBridge,+spec-ctrl
All nodes of the clusters are reporting:
> CPU Type:
> Intel SandyBridge IBRS Family
And the cluster is configured with:
> Cluster CPU Type:
> Intel SandyBridge IBRS Family
My quick fix for the vm was, that I used a specific (not the cluster
default) CPU-Model without the spectre/meltdown mitigation:
> Guest CPU Type:
> SandyBridge
I've also tried to select manually "SandyBridge,+spec-ctrl". But when I
do this the wizard blocks and surround the field with a red border (see
picture in the attachment).
Any idea?

ovirt 4.2 and hugepages
by Gianluca Cecchi
A part from configuring high performance vm, that gives me no high
availability.
Can I allocate huge pages
using vdsm-hook-hugepages-4.19.31-1.el7.centos.noarch
it seems that after updating an environment to 4.2 I'm not able to start a
VM configured with the custom property
I get
Th ehost xxxxx did not satisfy internal filter HugePages because there are
not enough free huge pages to run the VM
But on host I have
# cat /proc/meminfo | grep -i huge
AnonHugePages: 0 kB
HugePages_Total: 60000
HugePages_Free: 60000
HugePages_Rsvd: 0
HugePages_Surp: 0
Hugepagesize: 2048 kB
#
and the custom property is configured to allocate 8200 huge pages to the
guest
The gropu configured in sysctl.d/10-hugepages.conf is
vm.hugetlb_shm_group = 36
Do I have to set anything in /etc/securily/limits.d/ for qemu user?
Thanks In advance,
Gainluca

Gluster not synicng changes between nodes for engine
by Hanson Turner
Hi Guys,
I've got 60 some odd files for each of the nodes in the cluster, they
don't seem to be syncing.
Running a volume heal engine full, reports successful. Running volume
heal engine info reports the same files, and doesn't seem to be syncing.
Running a volume heal engine info split-brain, there's nothing listed in
split-brain.
Peers show as connected. Gluster volumes are started/up.
Hosted-engine --vm-status reports :
The hosted engine configuration has not been retrieved from shared
storage. Please ensure that ovirt-ha-agent is running and the storage
server is reachable.
This is leaving the cluster in an engine down with all vm's down state...
Thanks,

Install CiscoISE VM on oVirt
by Anantha Raghava
Hi,
I am not sure whether I should write it here. However the documents
referred to specifies that I have change something in BIOS of VM & there is
no way to get access to BIOS. Hence I am writing here.
I am trying to install Cisco ISE in a VM on oVirt. The installation process
halts reporting "Unsupported Hardware Found. The Cisco UDI (Unique Device
Identifier) found on this appliance does not match with supported UDI of
the product being Installed. Exiting installation"
However it works perfectly on VMWare ESXi, VMWare Workstation and VMWare
Fusion. In fact I tested this in VMWare Workstation and VMWare Fusion. The
same ISO file throws above error.
Cisco ISE is based on RHEL 7 and it is hardened.
Has any one attempted to install Cisco ISE in oVirt? Any one throw some
light?
My oVirt Version 4.2.3 and Hosts are on 4.1.9
Thanks & regards,
Anantha Raghava

Moving from thin to preallocated storage domains
by Albl, Oliver
Hi all,
I have to move some FC storage domains from thin to preallocated. I would set the storage domain to maintenance, convert the LUN from thin to preallocated on the array, remove "Discard After Delete" from the advanced settings of the storage domain and active it again. Is there anything else I need to take care of?
All the best,
Oliver
