I've searched on this issue all over the place and not found a full answer.
I've got a lab with older Dell PE860 servers with Pentium D processors. We
are attempting to prove out that we can move from VMware to KVM and oVirt,
but with 3.5 we can't get these servers to enter into a cluster due to the
age of the processors.
I've seen it referenced in a few list entries to modify 'the database' to
put CPUInfo entries in for the processor capabilities of this processor, but
it is unclear to me and I've been unable to find any documentation that
speaks to what database and how to modify it safely.
I know we could update these servers and get better power consumption, heat
generation, etc., but it's not in the cards and I can't move my newer
servers until we prove it out with these older ones, which ran ESXi 5.5 with
absolutely no issue. This cluster will be a functional test and small tools
cluster ultimately, so I don't really care about their lower end specs,
either.
Would installing something older than 3.5 help me here? Or is there some
doc somewhere I've just not found that describes this process of updating
the DB with these CPU parameters.
TIA!!

Systemd-Script to put the node in "maintenance" on shutdown
by Luca Bertoncello
Hi again,
I'm trying to write a systemd-script (for CentOS7) in order to automatically put the host in "maintenance" on shutdown and to activate it after boot.
I wrote a python-script that to that and it works so that I can start it and see the host in "maintenance" and having all VMs migrated.
Unfortunately I can't call this script on shutdown/reboot and wait until all VMs are migrated and the host is in maintenance.
Here my script:
[Unit]
Description=oVirt interface for managing host
After=remote-fs.target vdsmd.service multipathd.service libvirtd.service time-sync.target iscsid.service rpcbind.service supervdsmd.service sanlock.service vdsm-network.service
Wants=remote-fs.target vdsmd.service multipathd.service libvirtd.service time-sync.target iscsid.service rpcbind.service supervdsmd.service sanlock.service vdsm-network.service
[Service]
Type=simple
RemainAfterExit=yes
ExecStart=/usr/local/bin/ovirt-maintenance.sh active
ExecStop=/usr/local/bin/ovirt-maintenance.sh maintenance
KillMode=none
[Install]
WantedBy=multi-user.target
Could someone help me and say what I'm doing wrong?
Thanks a lot
Mit freundlichen Grüßen

Virtual appliance import question/problem
by Maurice James
------=_Part_674_1103437547.1442854627811
Content-Type: text/plain; charset=utf-8
Content-Transfer-Encoding: 7bit
I have a virtual mail security appliance that I am trying to import into oVirt 3.5.4. The appliance was built for kvm. it has a total of 5 scsi disks. I can convert and copy the OS disk only because it expands its self to full size.
The first problem that I have is that the disks expand to their full size when I convert the to an oVirt format
OS Disk
mail.qcow2 (74M) converts to main.img (294M)
Storage disks
250.qcow2 (256K) converts to 250.img (250GB)
1024.qcow2 (256K) converts to 1024.img (1TB)
2048.qcow2 (256K) converts to 2048.img (2TB)
4096.qvow2 (256K) converts to 4096.img (4TB)
8192.qcow2 (256K) converts to 8192.img (8TB)
The second problem is that these disks are scsi and ti does not seem to work using the virtio-scsi selection. I tried selecting the IDE option, but there is a limit to the number of IDE disks that I can use.
Virtualbox has no issues running the appliance that was distributed in the ova format. Any help would be appreciated

Fixing the first error, we see now the real error; libvirt cannot handle
this vm configuration. We will ask one of the libvirt guys to look into
this.
You may try to disable the cdrom device on that vm, which is probably
useless now.

Cannot mount gluster storage data

And nothing server side.
I suppose it is a version issue since on server side I have
glusterfs-api-3.6.3-1.el6.x86_64
glusterfs-fuse-3.6.3-1.el6.x86_64
glusterfs-libs-3.6.3-1.el6.x86_64
glusterfs-3.6.3-1.el6.x86_64
glusterfs-cli-3.6.3-1.el6.x86_64
glusterfs-rdma-3.6.3-1.el6.x86_64
glusterfs-server-3.6.3-1.el6.x86_64
and on the new host :
glusterfs-3.7.4-2.el6.x86_64
glusterfs-api-3.7.4-2.el6.x86_64
glusterfs-libs-3.7.4-2.el6.x86_64
glusterfs-fuse-3.7.4-2.el6.x86_64
glusterfs-cli-3.7.4-2.el6.x86_64
glusterfs-server-3.7.4-2.el6.x86_64
glusterfs-client-xlators-3.7.4-2.el6.x86_64
glusterfs-rdma-3.7.4-2.el6.x86_64
But since it is a production system, i'm not sure about a performing
gluster server upgrade.
Mounting a gluster volume as NFS is possible (the engine data storage
has been mounted).
I'm asking here because glusterfs comes from the ovirt3.4 rpm repository.
If anyone have a hint to this problem
thanks
Jean-Michel

But since it is a production system, i'm not sure about a
performing gluster server upgrade.
<br>
Mounting a gluster volume as NFS is possible (the engine data
storage has been mounted).
<br>
<br>
I'm asking here because glusterfs comes from the ovirt3.4 rpm
repository.

If anyone have a hint to this problem

Cannot mount gluster storage data
by Jean-Michel FRANCOIS
Hi Ovirt users,
I'm running ovirt hosted 3.4 with gluster data storage.
When I add a new host (Centos 6.6) the data storage (as a glsuterfs)
cannot be mount.

Strange disk behaviour within VMs
by Morten A. Middelthon
Hi,
last Sunday I experienced a power outage with one of my two oVirt
hypervisors. After power was restored I experienced some weirdness:
- on one of the VMs running on this hypervisor the boot disk changed, so
it was no longer able to boot. Looking at the console the VM would hang
on "Booting from hard disk". After I noticed that the wrong virtual disk
was marked as OS/bootable I got it booting again after correcting it to
the proper boot disk. This was done from the oVirt management server.
- on another VM I tried today to add another virtual disk to expand a
LVM volume. In dmesg I can see the new device:
[17167560.005768] vdc: unknown partition table
However, when I tried to run pvcreate I got an error message saying that
this was already marked as an LVM disk, and then running pvs give me the
following error:
# pvs
Couldn't find device with uuid 7dDcyq-TZ6I-96Im-lfjL-cTUv-nff1-B11Mm7.
PV VG Fmt Attr PSize PFree
/dev/vda5 rit-kvm-ssweb02 lvm2 a-- 59.76g 0
/dev/vdb1 vg_syncshare lvm2 a-- 500.00g 0
/dev/vdc1 VG_SYNCSHARE01 lvm2 a-- 400.00g 0
unknown device VG_SYNCSHARE01 lvm2 a-m 1024.00g 0
As you can see there's already a PV called /dev/vdc1, as well another
one named "unknown device". These two PVs belong to a VG that does NOT
belong to this VM, VG_SYNCSHARE01. The uuids for these two PVs are:
--- Physical volume ---
PV Name unknown device
VG Name VG_SYNCSHARE01
PV Size 1024.00 GiB / not usable 3.00 MiB
Allocatable yes (but full)
PE Size 4.00 MiB
Total PE 262143
Free PE 0
Allocated PE 262143
PV UUID 7dDcyq-TZ6I-96Im-lfjL-cTUv-nff1-B11Mm7
--- Physical volume ---
PV Name /dev/vdc1
VG Name VG_SYNCSHARE01
PV Size 400.00 GiB / not usable 3.00 MiB
Allocatable yes (but full)
PE Size 4.00 MiB
Total PE 102399
Free PE 0
Allocated PE 102399
PV UUID oKSDoo-3pxU-0uue-zQ0H-kv1N-lyPa-P2M2FY
The two PVs which doesn't belong on this VM actually belongs to a
totally different VM.
On VM number two:
# pvdisplay
--- Physical volume ---
PV Name /dev/vdb1
VG Name VG_SYNCSHARE01
PV Size 1024.00 GiB / not usable 3.00 MiB
Allocatable yes (but full)
PE Size 4.00 MiB
Total PE 262143
Free PE 0
Allocated PE 262143
PV UUID 7dDcyq-TZ6I-96Im-lfjL-cTUv-nff1-B11Mm7
--- Physical volume ---
PV Name /dev/vdd1
VG Name VG_SYNCSHARE01
PV Size 400.00 GiB / not usable 3.00 MiB
Allocatable yes (but full)
PE Size 4.00 MiB
Total PE 102399
Free PE 0
Allocated PE 102399
PV UUID oKSDoo-3pxU-0uue-zQ0H-kv1N-lyPa-P2M2FY
As you can see, same uuid and VG name, but two different VMs.
My setup:
oVirt manager: oVirt 3.5 running on CentOS 6.7
oVirt hypervisors: two oVirt 3.5 servers running on CentOS 6.7
During the time of the power outage mentioned earlier I was running
oVirt 3.4, but I upgraded today and rebooted the manager and both
hypervisors, but NOT the VMs.
Virtual machines:
Debian wheezy 7.9 x86_64
Storage:
HP LeftHand iSCSI
I have tried to locate error messages in the logs which can be related
to this behaviour, but so far no luck :(

Hi,
I am not able to resume a VM which was paused because of gluster
client quorum issue. Here is what happened in my setup.
1. Created a gluster storage domain which is backed by gluster volume
with replica 3.
2. Killed one brick process. So only two bricks are running in replica 3
setup.
3. Created two VMs
4. Started some IO using fio on both of the VMs
5. After some time got the following error in gluster mount and VMs
moved to paused state.
" server 10.70.45.17:49217 has not responded in the last 42
seconds, disconnecting."
"vmstore-replicate-0: e16d1e40-2b6e-4f19-977d-e099f465dfc6:

more gluster mount logs at http://pastebin.com/UmiUQq0F
6. After some time gluster quorum is active and I am able to write the
the gluster file system.
7. When I try to resume the VM it doesn't work and I got following error
in vdsm log.
