access to QEMU monitor
by Matthias Leopold 09 Apr '20

09 Apr '20

Hi, for educational purposes I'm trying to access the QEMU monitor of oVirt VMs. Can someone tell me how this can be done? Connecting to the unix socket with socat doesn't work, probably because it's not started with "server,nowait". Can the QEMU monitor be reached with the SPICE console? thx Matthias

Cannot upload image
by Green, Jacob Allen /C 07 Apr '20

07 Apr '20

Hello, I am in a precarious situation where I need to upload an image to the storage domain, I understand that normally you would achieve this via the upload button on the storage domain > Disks tab. However I currently do not have the ability to import the certificate. Is there a way from command line either on the RHV manager or otherwise to upload a qcow2 without using the image upload through the GUI? Thank you.

Gluster problems with new disk and device name change and overlap
by Gianluca Cecchi 07 Apr '20

07 Apr '20

Hi, I have configured a single host HCI environment through the GUI wizard in 4.3.9. Initial setup has thai layout of disks, as seen by the operating system: /dev/sda -> for ovirt-node-ng OS /dev/nvme0n1 --> for gluster, engine and data volumes /dev/nvme1n1 --> for gluster, vmstore volume So far so good and all is ok. I notice that, even with single path internal disks, at the end oVirt configures the gluster disks as multipath devices and LVM2 PV structure on top of the multipath devices. Is this for "code optimization" at low level or what is the rationale for that, as with Gluster normally you do use local disks and so single path? Multipath structure generated: [root@ovirt ~]# multipath -l nvme.8086-50484b53373530353031325233373541474e-494e54454c205353 dm-5 NVME,INTEL SSDPED1K375GA size=349G features='1 queue_if_no_path' hwhandler='0' wp=rw `-+- policy='service-time 0' prio=0 status=active `- 0:0:1:0 nvme0n1 259:0 active undef running eui.01000000010000005cd2e4b5e7db4d51 dm-6 NVME,INTEL SSDPEDKX040T7 size=932G features='1 queue_if_no_path' hwhandler='0' wp=rw `-+- policy='service-time 0' prio=0 status=active `- 2:0:1:0 nvme1n1 259:2 active undef running [root@ovirt ~]# Anyway, on top of the multipah devices On /dev/nvme0n1: gluster_vg_nvme0n1 volume group with gluster_lv_data and gluster_lv_engine On /dev/nvme1n1 gluster_vg_nvme1n1 volume group with gluster_lv_vmstore logical volume The problem arises when I add another nvme disk, that, occupying a PCI slot, it seems has always higher priority of the previous /dev/nvme1n1 disk and so takes its name.

The OS disk is seen as sda so it should not have problems with this Something like this: filter = [ "r|/dev/nvme|", "a|.*/|" ] And also I am not sure if I have to rebuild the initrd or not in this case and if so what would be the exact sequence of commands to execute. Any suggestions? Thanks in advance, Gianluca

Auto-logout while editing
by Shareef Jalloq 07 Apr '20

07 Apr '20

There's a rather annoying bug in the Engine UI where you can be logged out while actively using the system. I've been logged out twice now while editing the settings for a new VM. I'm screen grabbing and documenting as I go but I was just logged out while editing the System settings for a new VM. Shareef.

snapshot options on remote NFS storage
by Jayme 07 Apr '20

07 Apr '20

Was wondering if there are any guides or if anyone could share their storage configuration details for NFS. If using LVM is it safe to snapshot volumes with running VM images for backup purposes?

Hi Anton, Sure thing. During the creation of the NFS storage, you should specify an export path. SSHing that export path will expose you to the storage domain's content. You can visit the "Attaching NFS Storage" section in https://ovirt.org/documentation/admin-guide/chap-Storage.html *Regards,* *Shani Leviim* On Tue, Apr 7, 2020 at 1:37 PM Anton Louw <Anton.Louw(a)voxtelecom.co.za> wrote: > > > Hi Shani, > > > > Great, thank you very much. > > > > Do you perhaps know if I can access the storage domain if I SSH to a node? > For instance, if I want to access a “datastore” in VMware, I SSH to a host > and select /vmfs/volumes > > > > Is there anything like that available for oVirt? > > > > Thanks > > > > *Anton Louw* > *Cloud Engineer: Storage and Virtualization* at *Vox* > ------------------------------ > *T:* 087 805 0000 | *D:* 087 805 1572 > *M:* N/A > *E:* anton.louw(a)voxtelecom.co.za > *A:* Rutherford Estate, 1 Scott Street, Waverley, Johannesburg > www.vox.co.za > > [image: F] <https://www.facebook.com/voxtelecomZA> > [image: T] <https://www.twitter.com/voxtelecom> > [image: I] <https://www.instagram.com/voxtelecomza/> > [image: L] <https://www.linkedin.com/company/voxtelecom> > [image: Y] <https://www.youtube.com/user/VoxTelecom> > > *From:* Shani Leviim <sleviim(a)redhat.com> > *Sent:* 07 April 2020 11:35 > *To:* Anton Louw <Anton.Louw(a)voxtelecom.co.za> > *Cc:* users(a)ovirt.org > *Subject:* Re: [ovirt-users] Mount ISO to VM > > > > Hi Anton, > > You can upload an ISO file as a disk using the UI: > > Storage -> Disks -> upload. > > Further information can be found here under the "Uploading a Disk Image to > a Storage Domain" section: > > https://www.ovirt.org/documentation/admin-guide/chap-Virtual_Machine_Disks.… > > > > Or use the following script using SDK: > https://github.com/oVirt/ovirt-engine-sdk/blob/master/sdk/examples/upload_d… > > > *Regards,* > > *Shani Leviim* > > > > > > On Tue, Apr 7, 2020 at 11:45 AM Anton Louw <Anton.Louw(a)voxtelecom.co.za> > wrote: > > > > Hi Everybody, > > > > Is there a way to mount an ISO to one of my VMs if I do not have an ISO > domain, but the ISO file is on a Data domain? > > > > Thanks > > > > *Anton Louw* > > *Cloud Engineer: Storage and Virtualization* at *Vox* > ------------------------------ > > *T:* 087 805 0000 | *D:* 087 805 1572 > *M:* N/A > *E:* anton.louw(a)voxtelecom.co.za > *A:* Rutherford Estate, 1 Scott Street, Waverley, Johannesburg > www.vox.co.za > > > > <https://www.facebook.com/voxtelecomZA> > > <https://www.facebook.com/voxtelecomZA> > > <https://www.facebook.com/voxtelecomZA> > > <https://www.facebook.com/voxtelecomZA> > > <https://www.facebook.com/voxtelecomZA> > > <https://www.facebook.com/voxtelecomZA> > > <https://www.facebook.com/voxtelecomZA> > > <https://www.facebook.com/voxtelecomZA> > > <https://www.facebook.com/voxtelecomZA> > > <https://www.facebook.com/voxtelecomZA> > > <https://www.facebook.com/voxtelecomZA> > > <https://www.facebook.com/voxtelecomZA> > > > *Disclaimer* <https://www.facebook.com/voxtelecomZA> > > The contents of this email are confidential to the sender and the intended > recipient.

ISO and Export domains deprecated
by Colin Coe 07 Apr '20

07 Apr '20

Hi all I'm trying to understand how ISO and Export domains going away is going to affect us. We have four RHV instances: - Prod DC1 (RHV4.1) - Prod DC2 (RHV4.1) - DEV (RHV4.3) - TEST (RHV4.3) Prod DC1, DEV and TEST all share export and ISO domains. Prod DC2 is remote and currently has its own ISO and Export domains. When ISO and Export domains go away, can I still share ISO domains between the RHV instances? Thanks
