removal of vdsm-hook-macspoof
by Dan Kenigsberg
vdsm-hook-macspoof was created to let VM owners override the
vdsm-no-mac-spoofing that was once hard-coded on each vNIC.
Since ovirt-4.0's
Bug 1317441 - [RFE] Allow MAC Anti-Spoofing per interface instead of globally
the hook is no longer needed, because ovirt-engine supports selection
of filters, including the "Empty" one.
Thus, we can finally drop vdsm-hook-macspoof from vdsm code.
https://gerrit.ovirt.org/#/c/94613/ does that.
If someone still depends on setting the ifacemacspoof custom property,
they can find and fix the vnic profiles using a script similar to the
following one. Note that ovirtlib does not yet have an easy-to-pull
canonical location.
from __future__ import print_function
import sys
from ovirtlib.system import SDKSystemRoot
from ovirtlib.netlib import Network, VnicProfile,
CustomProperty, NetworkFilter
from ovirtlib.datacenterlib import DataCenter
system = SDKSystemRoot()
system.connect(url=URL, insecure=True, password=PASSWORD, username=USER)
spoof_cp = CustomProperty(name='ifacemacspoof', value='true')
broken_profiles = [
profile for profile in VnicProfile.iterate(system)
if spoof_cp in profile.custom_properties and
profile.filter and profile.filter.name ==
'vdsm-no-mac-spoofing']
if broken_profiles:
if '--modify' in sys.argv:
print('clearing vdsm-no-mac-spoof filter from profiles:')
for profiles in broken_profiles:
print(profile.name)
profile.filter = None
else:
print('''ifacemacspoof custom property is no longer
supported by vdsm.
vnic profiles that depended on it for connectivity, e.g they
serve VMs with
in-guest bonds or vlans, must use an empty network filter instead.
profiles with ifacemacspoof and vdsm-no-mac-spoof filter:''')
for profiles in broken_profiles:
print(profile.name)
print('run again with --modify to remove the filter')
else:
print('no profile with ifacemacspoof and vdsm-no-mac-spoof
was found.')

Resuming VM from suspend that is based on iscsi/fc raise an exception.
by 王猛
Hi,
When I resume a VM from suspend that is based on iscsi or fcp, there's always an exception:
-----
2019-04-17 19:33:58,835+0800 ERROR (vm/baaabf11) [virt.vm] (vmId='baaabf11-172d-4fac-9862-86ff05feb085') The vm start process failed (vm:937)

394 (code=1) (vm:1675)
----------
After i read the Bug 1503468 (https://bugzilla.redhat.com/show_bug.cgi?id=1503468#c40), I know the reason why that happened.
But how should I avoid this exception? The only method i know and tested is to change gzip to lzop in /etc/libvirt/qemu.conf. But this is
not the way to solve the problem.

Re: Arbiter brick disk performance
by Strahil
I think 2 small ssds (raid 1 mdadm) can do the job better as ssds have lower latencies .You can use them both for OS (minimum needed is 60 GB) and the rest will be plenty for an arbiter.
By the way, if you plan using gluster snapshots - use thin LVM for the brick.
Best Regards,

NVME-oF
by Daniel Menzel
Hi guys,
just out of curiosity: Have there been any attempts yet to use NVMe over
Fabrics as Storage-Backend in oVirt? We have used NVMe-oF several times
in the past few weeks/month and its an absolutely gorgeous technology -
and more than perfect for virtualization.
Best
Daniel

Re: Ovirt 4.3.2 VM Failover
by Strahil
I have noticed after full power failiure (all nodes simultaneously - labs don't have UPS yet) one of my VMs was in that state, and I had to restart VDSM in order the engine to notice the crash.
Definitely , there is something phishy here...
I guess Sahina & Sandro can take a look in your case..

Ovirt 4.3.2 VM Failover
by michael＠wanderingmad.com
Is there something in the 4.3.x series that has changed when it comes to VM failover? I have the cluster configurated to automatically migrate all server VMs, but whenever One of the nodes goes down, all the VMs that were on that host switch to a ? status and I have to go and click "host has been rebooted" to have them failed over.

Adding network to VM - What stupid thing have I missed?
by eshwayri＠gmail.com
When creating a new VM, it looks like I connect it's nic(s) under the "Instantiate VM network interfaces by picking a vNIC profile." setting. The problem I am seeing is that the drop down only has "Empty" and "br-kvm-prod" (my production bridge). I should have two more. Under Networks and vNIC Profiles tabs, I also have a br-kvm-stor and kvm_heart-22 defined which don't appear in that list. Am I missing something I need to do for these additional profiles to also appear in the drop-down? Some of my VMs will need access to the other physical networks.

New disk creation very slow after upgrade to 4.3.3
by Steffen Luitz
This is on a 3-node hyperconverged environment with glusterfs.
After upgrading to oVirt 4.3.3 (from 4.3.2) creating a new disk takes very long (hours for a 100GByte disk, making it essentially impossible to create a new disk image).
In the UI the default is "preallocated" but changing it to thin provision does not make any difference. Regardless of this setting, an fallocate process gets started on the SDM host:
/usr/bin/python2 /usr/libexec/vdsm/fallocate 107374182400 /rhev/data-center/mnt/glusterSD/s-vmhost2-ovir.t...
Using fallocate to create a file directly on the underlying file system is fast. Using it to create a file through the glusterfs fuse mount is very slow.
Thanks for any insights.
