paused vm's will not resume
by eevans＠digitaldatatechs.com
I have 2 vm's, which are the most important in my world, that paused and will not resume. I have googled this to death but no solution. It stated a lack of space but none of the drives on my hosts are using more than 30% or there space and these 2 have ran on kvm host for several years and always had at least 50% free space.
I like ovirt and want to use it but I cannot tolerate the down time. If I cannot get this resolved, I'm going back to kvm hosts. I am pulling my hair out here.
If anyone can help with this issue, please let me know.

Hugepages and running out of memory
by klaasdemter＠gmail.com
Hi,
this e-mail is meant to caution people using hugepages and mixing those
VMs with non-hugepages VMs on the same hypervisors. I ran into major
trouble, the hypervisors ran out of memory because the VM scheduling
disregards the hugepages in it's calculations. So if you have hugepages
and non-hugepages VMs better check the memory commited on a hypervisor
manually :)
https://bugzilla.redhat.com/show_bug.cgi?id=1804037
https://bugzilla.redhat.com/show_bug.cgi?id=1804046
As for workarounds: so far it seems the only viable solution is
splitting hugepages/nonhugepages VMs with affinity groups but at least
for me that means wasting a lot of resources.
Greetings

main channel: failed to connect HTTP proxy connection not allowed
by Jorick Astrego
Hi,
Having a spice console issue on our new 4.3.8 cluster. The console stays
blank and with the cli and debug on, I get the following error "main
channel: failed to connect HTTP proxy connection not allowed"
We have a userportal through haproxy so this is configured in ovirt engine
engine-config -g SpiceProxyDefault
SpiceProxyDefault: http://userportal.*.*:****/ version: general
But the same setting works fine on our 4.2 cluster.
I can telnet to the ports on the 4.3.8 hosts without issue.

Understanding dashboard memory data
by nux＠li.nux.ro
Hello,
I'm having to deal with an oVirt installation, once I log in the
dashboard says:
Memory: "1.2 Available of 4.5 TiB" and "Virtual resources - Committed:
113%, Allocated: 114%".
So, clearly there is RAM available, but what's with the committed and
allocated numbers?

Ovirt storage domain ovirt-image-repository is unattached and can't use change CD to install windows on VM
by Heinrich Momberg
Good day,
Whenever i am trying to use the change CD to mount the ovirt tools iso so i can install windows server or any windows it says "could not find ISO file collection".It doesn't pick up the hdd that i have created in the windwos setup so i have to do the whole ovirt tools mount and select the windows i want to insteall etc. It has been working fine until a couple of days ago when we had power outages. I also noticed that the storage domain,ovirt-image-repository is unattached... How do i go about fixing this problem or where can i check logs. I have checked the permissions where the ISO's or images are stored.

Spacewalk Integration
by eevans＠digitaldatatechs.com
I finally figured out how to use Spacewalk as an external provider in Ovirt.
For the URL I used http://sat.digitaldatatechs.com/XMLRPC and used the admin login credentials. It registered and Spacewalk has the capability of provisioning a bare bones machine.
I have not tested provisioning but I will comment once I do.

Get CPU Family
by Luca
Hello guys,
how can I get the correct CPU Family in a ovirt host?
When I execute virsh -r capabilities I get only "Broadwell-noTSX-IBRS" and not the full "Broadwell-noTSX IBRS SSBD MDS"

Unsynced entries do not self-heal during upgrade from oVirt 4.2 -> 4.3
by Goorkate, B.J.
Hi all,
I'm in the process of upgrading oVirt-nodes from 4.2 to 4.3.
After upgrading the first of 3 oVirt/gluster nodes, there are between 600-1200 unsynced entries for a week now on 1 upgraded node and one not-yet-upgraded node. The third node (also not-yet-upgraded) says it's OK (no unsynced entries).
The cluster doesn't seem to be very busy, but somehow self-heal doesn't complete.
Is this because of different gluster versions across the nodes and will it resolve as soon as I upgraded all nodes? Since it's our production cluster, I don't want to take any risk...
Does anybody recognise this problem? Of course I can provide more information if necessary.
Any hints on troubleshooting the unsynced entries are more than welcome!
Thanks in advance!
Regards,
Bertjan
