I have attached 7TB disk ( pre allocated) for VM ( Redhat 8 ).. Due to
some space issue we have unattached disk from VM and deleted it. but free
space still has not changed and we can't use that space for other purposes

What would be the issue ?
Thanks,

Unable to migrate VMs to or from oVirt node 4.4.7

Hi All,
After upgrading some of my hosts to 4.4.7, and after fixing the policy issue, I'm no longer able to migrate VMs to or from 4.4.7 hosts. Starting them works fine regardless of the host version.

Q: Strange ping timeouts/network issues when 1 node is down
by Andrei Verovski
Hi,
I have observed strange ping timeouts/network issues when one of nodes is down, for example, for RAM upgrade.
Powering up and connecting node back solves this.
Each node have 2 networks (connected to different Ethernet interfaces), ovirtmgmt 192.168.0.xxx and DMZ 192.168.1.x.
Additionally, time consuming operations like VM cloning causes increase of ping latency to ALL nodes from local workstations.
VM cloning should load only 1 node but it should not affect the whole ovirt mgmt network on all nodes.
How to fix this issue?
Thanks in advance for any help.
Andrei

I cannot link these errors to any storage/fs issue (in dmesg or
/var/log/messages), brick devices looks healthy (smartd).
I can force start brick with
gluster volume start vms|engine force
and after some healing all works fine for few days
Did anybody observe this behavior?
vms volume has this structure (two bricks per host, each is separate
JBOD ssd disk), engine volume has one brick on each host...

export VM from oVirt engine 3.5
by fddi＠comcast.net
Hello,
I am trying to export a bunch o VM from oVirt version 3.5
The problem is that there is no OVA support for exporting them. I also tryed to export VMs into OVA format using ovirtsdk4 which anyway won't work on oVirt 3.5.
I can successfully export to a NFS partition but for each VM there are several qcow v2 files which I suppose to be the VM image and its snapshots.
How to identify the correct file to represent the current VM status ?
If I delete all the snapshots, will I end up with only one valid qcow v2 image that I can use ?

passing data between guacamole and xrdp server
by Jason Keltz
Hi.
I have a custom use case where I would like to have two guacamole RDP
connections that point to the same host, but the underlying xrdp start
script would initialize one connection slightly different than the
other. I don't see a simple way that I can pass anything between
Guacamole and the xrdp server which would allow the script to determine
which connection the user chose in guac? I thought *maybe* "client
name" under "Basic Settings" but it seems to apply to Windows only. It
would be neat to be able to pass environment variables in.
Thanks,
Jason.
