what is the best practices to delete vdisks in 100% used gluster stoargedoamin
by dhanaraj.ramesh＠yahoo.com
Hi Team
In my one of three node Hyperconverged (gluster + ovirt) setup, one of the storage domain went offline from Datacenter due to 100% storage space utilization, but luckily it is still online in Gluster. how should I properly delete some of the vdisks in that offline stoarge domain from Gluster and bring back to online?

ovirt importing vm stuck
by Sudhakar S
Hi Team,
I have initiated a VM import from VMware using Import as OVA option in
Ovirt.
I started importing and all going good but it is stuck at the last. Please
find the below attached screenshot FYR.
Please suggest me your steps to stop this task since it is running for a
whole day.

(try to add '--allowerasing' to command line to replace conflicting packages or '--skip-broken' to skip uninstallable packages or '--nobest' to use not only best candidate packages)
Running dnf distro-sync --nobest allows it to proceed, which causes some ovirt packages to be upgraded.
Running hosted-engine --deploy and installing with nfs storage, everything goes good up until stage 5, at which point vdsm pegs a core at 100% for some minutes, until the task inevitably fails. hosted-engine --vm-status reports EngineStarting forever. No memory is consumed to indicate that the VM even started. The VM never even tries to get a DHCP lease from my router. All indicators point the vm just not starting, for some reason.
Zero useful information available on Google. Zero useful information available in the documentation. Zero useful information available in the logs. No clear cause as to why the hosted engine refuses to start. The NFS share has correct permissions, and can be mounted. The NFS share is on the same host the engine is being installed to, in the same subnet/vlan and, even through the same network adapter. The shared storage works fine for copying the local hosted engine to the shared storage during the setup process and I can see the files have been created.

on-demand machine creation for VDI project
by Luca Contessa
Hi List,
I've made an oVirt node installation (oVirt ver. 4.4.9) for a VDI project and I'd like to ask if it is possible to create an empty pool with a maximum number of machine and as the machine are required by the end user (so when the users use the think client to request the provisioning of a machine of the pool in question) the pool will dynamically create the machine and link it to the end user.
To specify once more the pool will be create with no machine in it, only a maximum limit on the number of machines, and as the user start connecting to the pool the VM will be created, started and provisioned to the user requesting them.
Then when the user stop using the machine they would like the system to save the datas and stop the machine and from that point on when the user will connect the virtual machine connected to their account on the AD system should start.
Do you know if this is possibile?
Thanks a lot to everybody,
Luca

How to turn off the state of tlbflush for Windows vm
by Hean-Seng Tan
We encounter random Windows BSOD (blue screen of death) issues for vm's in environment running oVirt Engine 4.4.4. Upgrading the environment to 4.4.8 does not fix the issue. There is a suggestion from https://bugzilla.redhat.com/show_bug.cgi?id=1868572 to turn off the state of tlbflush under hyperv section for the Windows vm. Does anyone know how to achieve that?
Currently, vm description returned from api call includes the following section that has tlbflush state:
<features>
<acpi/>
<hyperv>
<relaxed state='on'/>
<vapic state='on'/>
<spinlocks state='on' retries='8191'/>
<vpindex state='on'/>
<runtime state='on'/>
<synic state='on'/>
<stimer state='on'/>
<reset state='on'/>
<frequencies state='on'/>
<reenlightenment state='on'/>
<tlbflush state='on'/>
</hyperv>
</features>

How to set Disk profile via REST API?
by ovirt.org＠nevim.eu
Hi,
I have ovirt version: 4.3.4.3-1.el7 I can't find in the documentation how to set up a server disk profile during creation via the REST API. If it didn't work during creation, then it doesn't matter later after creation.
How to please set up a disk profile server via REST API?
Thank you.

Moving backing datastores from NFS to iSCSI
by David Johnson
Hello braintrust,
My ovirt cluster is prone to hanging when it is put under a high IO load.
In an earlier thread, someone determined that this is consistent across
architectures and infrastructures when NFS is used for the backing
datastore for the cluster.
I was able to see a huge improvement by switching putting an nVME drive in
as the intent log cache on the NAS. But, alas, that appears to have only
put off the reckoning, and the cluster locked up again when I doubled the
IO workload.
Prior email chains to this list have established that the hang occurs
because "something" in qemu throws the VM into PAUSE state instead of
IOWAIT state when under load. Other emails I have viewed seem to point at
NFS as the root cause, so a "least cost" suggestion is to migrate from NFS
to iSCSI as backing storage.
Is there an existing procedure for migrating Ovirt VM storage from NFS to
iSCSI?
Current architecture:
Ovirt engine 4.4.4.7-1.el8 on centos 8.x, on bare metal intel desktop
2 hosts 4.4.4.7-1.el8 on centos 8.x
TrueNAS Core 2020, with shares exposed as NFS
10 GBit dedicated storage Network
Thanks,
*David Johnson*
