Hello, I have a question about cloud-init:
After installing vm, I installed cloud-init immediately, and enabled its
four services, and then I can use cloud-init in the admin interface.
However, I don't know how cloud-init knows where to get the relevant
information (such as host name, SSH secret key, etc.) that I configured on
the admin interface ? For I haven't configured the data source for
Why it can works ?
I have recently added a fresh installed host on 4.4, with 3 x nvidia gpu's
which have been passed through to a guest VM instance. The host also has a
1TB nvme SSD drive which we are using for the host OS install and /var/
partition size was modified to allow maximum space for the guest, the
intent is to give maximum space to a guest for fast SSD storage. Because
this is a partition, I have about 700GB that can be added or mapped to a
guest "disk" image that is locked to the host.
After doing the above and after learning how simple it was to map the three
GPUs in pass-through mode, my question is - can I simply map a PCI SSD
through to a guest in the same fashion as the GPUs?
I have not yet tried and do not find much results via google search. The
intent on this would be to provision the whole SSD to the guest (instead of
using the SSD for the host OS and some of that space for a guest (disk)
image. In this case I would use another disk for the host OS but that is
Has anyone done such a thing (PCI SSD passthrough) and are there any
concerns? (apart from the normal concerns with VM and host passthrough)
Good day to all,
I have a question about the console configuration of the VMs:
By default, for each console connection to a VM, a password is set for
120 seconds, after that you can't use it again. We currently have the
We want to access and control the VMs via the VNC/Spice of the Ovirt
host. We have already tried to use the password from the console.vv for
the connection and that works so far. Unfortunately we have to do this
every 2 minutes when we want to connect again. We are currently building
an automatic test pipeline and for this we need to access the VMs
remotely before OS start and we want to be independent of a VNC server
on the guest. This is only possible if we could connect to the VNC/Spice
server from the Ovirt host.
My question: would it be possible to fix the password or read it out via
api every time you want to connect?
I would appreciate a reply very much!
i get the below error when i try to add a new kvm host to the cluster. I know that the cpu is a haswell. if i run "virsh capabilities" it returns
<model>Haswell-noTSX-IBRS</model>. My KVM server is redhat 8.4 fully patched today on an DL-360 Gen9. oVirt is at 220.127.116.11-1.el8. i have tried many diffent CPU settings for the cluster and none of them work. this is new oVirt install.
"The host CPU does not match the Cluster CPU Type and is running in a degraded mode. It is missing the following CPU flags: vmx, model_Haswell-noTSX, nx. Please update the host CPU microcode or change the Cluster CPU Type."

on a 4.4.6 environment where I'm moving storage I want to change the lease
domain for an HA VM.
The VM is running and if I go and edit, change sd and then press ok button,
I get a window with:
Changes that can be applied immediately:
I don't select the "apply later" check box. But then instead when I
confirm, I get an error window with:
Cannot edit VM. Hot swapping of VM leases is not supported, please
remove the current lease and then set a new one.
Possibly it is possible to hot add a lease but not swap? So I think the
first window should be changed. Is this a known issue?
No problem if I change the lease storage domain while the VM is powered off.
I don't know if it is already fixed in 4.4.7... I'm going to check next
+Bella Khizgiyaev <bkhizgiy(a)redhat.com> can you please take a look?
