removal of vdsm-hook-macspoof
by Dan Kenigsberg 28 Apr '19

28 Apr '19

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.

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) 378 Traceback (most recent call last): 379 File "/usr/lib/python2.7/site-packages/vdsm/virt/vm.py", line 866, in _startUnderlyingVm 380 self._run() 381 File "/usr/lib/python2.7/site-packages/vdsm/virt/vm.py", line 2819, in _run 382 self._connection.restore(fname) 383 File "/usr/lib/python2.7/site-packages/vdsm/common/libvirtconnection.py", line 131, in wrapper 384 ret = f(*args, **kwargs) 385 File "/usr/lib/python2.7/site-packages/vdsm/common/function.py", line 94, in wrapper 386 return func(inst, *args, **kwargs) 387 File "/usr/lib64/python2.7/site-packages/libvirt.py", line 4513, in restore 388 if ret == -1: raise libvirtError ('virDomainRestore() failed', conn=self) 389 libvirtError: internal error: Child process (gzip -dc) unexpected exit status 2: 390 gzip: stdin: decompression OK, trailing garbage ignored 391 392 2019-04-17 19:33:58,835+0800 INFO (vm/baaabf11) [virt.vm] (vmId='baaabf11-172d-4fac-9862-86ff05feb085') Changed state to Down: internal error: Child process (gzip -dc) unexpected exit status 2: 393 gzip: stdin: decompression OK, trailing garbage ignored 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. -- 王猛软件研发手机：13021702660 地址：济南市高新区银荷大厦B座10层 250101 邮箱: wang_meng(a)massclouds.com 网址: www.massclouds.com 山东乾云启创信息科技有限公司

Re: Arbiter brick disk performance
by Strahil 28 Apr '19

28 Apr '19

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.

NVME-oF
by Daniel Menzel 26 Apr '19

26 Apr '19

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.

Re: Ovirt 4.3.2 VM Failover
by Strahil 26 Apr '19

26 Apr '19

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 26 Apr '19

26 Apr '19

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.

All Windows vms report "Actual timezone in guest doesn't match configuration"
by michael＠wanderingmad.com 26 Apr '19

26 Apr '19

All of my windows VMs have a yellow exclamation point with the timezone error. The configuration in ovirt says eastern time, and I've tried changing the VM from eastern time to US eastern time, and error does not go away. This is with the latest ovirt guest tools for windows.

Adding network to VM - What stupid thing have I missed?
by eshwayri＠gmail.com 25 Apr '19

25 Apr '19

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 25 Apr '19

25 Apr '19

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. Steffen
