[ANN] oVirt 4.4.3 Seventh Release Candidate is now available for testing
by Lev Veyde
oVirt 4.4.3 Seventh Release Candidate is now available for testing
The oVirt Project is pleased to announce the availability of oVirt 4.4.3
Seventh Release Candidate for testing, as of October 29th, 2020.
This update is the third in a series of stabilization updates to the 4.4
series.
How to prevent hosts entering emergency mode after upgrade from oVirt 4.4.1
Note: Upgrading from 4.4.2 GA should not require re-doing these steps, if
already performed while upgrading from 4.4.1 to 4.4.2 GA. These are only
required to be done once.
Due to Bug 1837864 <https://bugzilla.redhat.com/show_bug.cgi?id=1837864> -
Host enter emergency mode after upgrading to latest build
If you have your root file system on a multipath device on your hosts you
should be aware that after upgrading from 4.4.1 to 4.4.3 you may get your
host entering emergency mode.
In order to prevent this be sure to upgrade oVirt Engine first, then on
your hosts:
1.
Remove the current lvm filter while still on 4.4.1, or in emergency mode
(if rebooted).
2.
Reboot.
3.
Upgrade to 4.4.3 (redeploy in case of already being on 4.4.3).
4.
Run vdsm-tool config-lvm-filter to confirm there is a new filter in
place.
5.
Only if not using oVirt Node:
- run "dracut --force --add multipath” to rebuild initramfs with the
correct filter configuration
6.
Reboot.

Hosted Engine install via cockpit - proxy issue
by simon＠justconnect.ie
I am installing oVirt in a closed environment where internet access is controlled by proxies.
This works until the hosted engine install via cockpit where it fails to complete as it appears to require internet access to the repository.
The only workaround I have found is to ssh onto the engine ‘mid install’ and add the proxy address to /etc/dnf/dnf.conf. After doing this the install is successful.
Am I missing something or does this type of install require unfettered internet access?

when configuring multi path logical network selection area is empty, hence not able to configure multipathing
by dhanaraj.ramesh＠yahoo.com
Hi team,
I have 4 node cluster where in each node I configured 2 dedicated 10 gig NIC with
dedicated subnet each ( NIC 1 = 10.10.10.0/24, NIC 2 = 10.10.20.0/24 ) and on the array
side I configured 2 targets with 10.10.10.0 /24 & another 2 target with 10.10.20.0/24
subnet. without any errors I could check in all four paths and able to mount iscsi luns in
all 4 nodes. However when i try to configure mutipathing at Data center level I could see
all the paths but not the logical network, it stays empty although I configured logical
network label for both NICs with dedicated names as ISCSI1 & ISCI2. these logical
names visible and green at the host network level, no errors, they are just L2 IP config
Am I missing something here? what else I should do to enable multiplathing

SPICE proxy behind nginx reverse proxy
by Colin Coe
Hi all
As per $SUBJECT, I have a SPICE proxy behind a reverse proxy which all
external VDI users are forced to use.
We've only started doing this in the last week or so but I'm not getting
heaps of reports SPICE sessions "freezing". The testing that I've done
shows that a SPICE session that is unattended for 10-15 minutes hangs or
freezes. By this I mean that you can't interact with the VM (using SPICE)
via mouse or Keyboard. Restarting the SPICE session fixes the problem.
Is anyone else doing this? If so, have you noticed the SPICE session
freezes?
Thanks in advance

Re: vdsm with NFS storage reboot or shutdown more than 15 minutes. with error failed to unmount /rhev/data-center/mnt/172.18.81.14:_home_nfs_data: Device or resource busy
by Strahil Nikolov
When you set a host to maintenance from oVirt API/UI, one of the tasks is to umount any shared storage (incluing the NFS you got). Then rebooting should work like a charm.
Why did you reboot without putting the node in maintenance ?
P.S.: Do not confuse rebooting with fencing - the latter kills the node ungracefully in order to safely start HA VMs on another node.
Best Regards,
Strahil Nikolov

How reproducible:
100%
Steps to Reproduce:
1. my test enviroment is one Ovirt engine(172.17.81.17) with 4 vdsm servers, exec "reboot" cmd in one of the vdsm servers(172.17.99.105), the server will reboot more than 30 minutes.ovirt-engine : 172.17.81.17/16
vdsm: 172.17.99.105/16
nfs server: 172.17.81.14/16Actual results:
As above. the server will reboot more than 30 minutes
Expected results:
the server will reboot in a short time.
What I have done:
I have capture packet in nfs server while vdsm is rebooting, I found vdsm is always sending nfs packet to nfs server circularly as follows:this is some log files while I reboot vdsm 172.17.99.105 in 2020-10-26 22:12:34. Some conclusion is:
1. the vdsm.log said the vdsm 2020-10-26 22:12:34,461+0800 ERROR (check/loop) [storage.Monitor] Error checking path /rhev/data-center/mnt/172.18.81.14:_home_nfs_data/02c4c6ea-7ca9-40f1-a1d0-f1636bc1824e/dom_md/metadata

Migrated disk from NFS to iSCSI - Unable to Boot
by Wesley Stewart
This is a new one.
I migrated from an NFS share to an iSCSI share on a small single node oVirt
system (Currently running 4.3.10).
After migrating a disk (Virtual Machine -> Disk -> Move), I was unable to
boot to it. The console tells me "No bootable device". This is a Centos7
guest.
I booted into a CentOS7 ISO and tried a few things...
fdisk -l shows me a 40GB disk (/dev/sda).
fsck -f tells me "bad magic number in superblock"
lvdisplay and pvdisplay show nothing. Even if I can't boot to the drive I
would love to recover a couple of documents from here if possible. Does
anyone have any suggestions? I am running out of ideas.

oVirt 4.4 Upgrade issue with pki for libvirt-vnc
by lee.hanel＠gmail.com
Greetings,
After reverting the ovirt_disk module to the ovirt_disk_28, I'm able to get passed that step, however now I'm running into a new issue.
When it tries to start the vm after moving it from local storage to the hosted storage, I get the following errors:
2020-10-27 21:42:17,334+0000 ERROR (vm/9562a74e) [virt.vm] (vmId='9562a74e-2e6c-433b-ac0a-75a2acc7398d') The vm start process failed (vm:872)

the permissions on the files appears to be correct.
https://bugzilla.redhat.com/show_bug.cgi?id=1634742 appears similar, but i took the added precaution of completely removing the vdsm packages and /etc/pki/vdsm and /etc/libvirt.
Anyone have any additional troubleshooting steps?

Gluster Domain Storage full
by suporte＠logicworks.pt
Hello,
I'm running oVirt Version 4.3.4.3-1.el7.
I have a small GlusterFS Domain storage brick on a dedicated filesystem serving only one VM.
The VM filled all the Domain storage.
The Linux filesystem has 4.1G available and 100% used, the mounted brick has 0GB available and 100% used
I can not do anything with this disk, for example, if I try to move it to another Gluster Domain Storage get the message:
Error while executing action: Cannot move Virtual Disk. Low disk space on Storage Domain
Any idea?
Thanks

oVirt 4.4 Upgrade issue?
by lee.hanel＠gmail.com
Greetings,
I'm trying to preform an upgrade from 4.3 to 4.4 using the hosted engine option of https://github.com/ovirt/ovirt-ansible-collection.
Unfortunately, when it goes to create the hosted engine disk images I get the following:
[Cannot move Virtual Disk. The operation is not supported for HOSTED_ENGINE_METADATA disks.]
This appears to be related to https://bugzilla.redhat.com/show_bug.cgi?id=1883817, BUT I've manually applied that patch. Shouldn't it be creating a NEW disk image instead of trying to move the existing one?
Any help would be appriciated.
Thanks,
Lee
