Virtual disk attached to VM showing in the Webui but not identified by the system
by Eugène Ngontang
Hi,
I'm facing a virtual disk behavior I don't understand.
Currently my VMs are spun up with a Boot disk of 25GB and an additional
disk of 215/45/65 GB depending.
When logged to the webui I see the two disks, but when I ssh to VM we only
see the primary boot disk, the other one can't get a *UUID* and then cannot
and is not mounted
I also noticed in the webui the second disk doesn't have a logical name as
you can see in the screenshot.
Pleas can someone explain this behavior please?
Here is my disk management commands outputs
[root@fp-gpu-node3 centos]# fdisk -l

Details about bios and custom emulated machine values
by Gianluca Cecchi
Hello,
in oVirt 4.3.7 in "Edit VM" -> System -> Advanced parameters
I can choose
Bios Type:
Default
Q35 Chipset with Legacy BIOS
Q35 Chipset with UEFI BIOS
Q35 Chipset with SecureBoot
and
Custom Emulated Machine:
Use cluster default (pc-i440fx-rhel7.6.0)
...
q35
pc-q35-rhel7.3.0
pc-q35-rhel7.4.0
pc-q35-rhel7.5.0
pc-q35-rhel7.6.0
and I can apparently mix all possible values.
Any deeper information about implications?
What is the "Default" value for Bios Type?
Did anything change in 4.3.8 (eg official support for q35)?
I search also through official docs for RHV 4.3 (virtual mgmt guide,
appendix A), but for example I don't find any reference to the "Bios Type"
parameter and a vague reference to the "Custom Emulated Machine". Is there
any more detailed link?
Thanks,
Gianluca

Problems in new oVirt install
by Steve Watkins
Got everything installed and was uploding an ISO when the system just stopped responding. Went to the host and saw the hostedengine was paused. Looked online and found the following instructions for unpausing it
virsh -c qemu:///system?authfile=/etc/ovirt-hosted-engine/virsh_auth.conf
resume HostedEngine
And get the following error
Failed to acquire lock: No space left on device
any ideas?

new install issues
by Steve Watkins
Very new to this, trying to work my way through it.
Got everything up and running, was uploading an ISO to try and start a vm and then everything just disconnected. On the host it shows the hostedengine as paused. Did some digging and found the suggestion to do the following:
virsh -c qemu:///system?authfile=/etc/ovirt-hosted-engine/virsh_auth.conf
resume HostedEngine
which gives me the message
Failed to acquire lock: No space left on device.
Ideas?

Cannot put host in maintenance mode
by Vinícius Ferrão
Hello,
I’m with an issue on one of my oVirt installs and I wasn’t able to solve it. When trying to put a node in maintenance it complains about image transfers:
Error while executing action: Cannot switch Host ovirt2 to Maintenance mode. Image transfer is in progress for the following (3) disks:
8f4c712e-66bb-4bfc-9afb-78407b8b726c,
eb0ef249-284d-4d77-b1f1-ee8b70718f3d,
73245a4c-8f56-4508-a5c5-2d7697f87654
Please wait for the operations to complete and try again.
I wasn’t able to find this image transfers. There’s nothing on the engine showing any transfer.
How can I debug this?
Thanks,

Subject: [ovirt-users] Windows Server Migration from Proxmox
Caution External Mail: Do not click any links or open any attachments unless you trust the sender and know that the content is safe.
I have several Windows systems I am trying to migrate from Proxmox. In each VM under Proxmox, I have removed all guest utilities and completed a clean shutdown.
I have successfully imported the disk image into oVirt and attached to a new VM with the same specs.
When I power on, though, they all give me a "kmode exception not handled".
Has anyone else run into this and successfully migrated a WIndows VM? These are primarily Server 2019 systems..

command line vm start/stop
by uran987＠gmail.com
Hello Experts.
In version 3.5.2.1-1.el6, we used an "ovirt-shell -E action..." command to start/stop virtual machines from command line. In version 4.3.7.2-1.el7 ovirt-shell is deprecated. Please advise how to start/stop them from command line. vdsm-client provides only destroy/shutdown/reset/cont, nothing about startvm or poweron.
Regards.

mirrors are still syncing, maybe you just hit a mirror which wasn't updated
yet.
Can you "yum clean metadata" and retry?
