VM stuck in paused mode with Cluster Compatibility Version 3.6 on 4.2 cluster
by Marco Lorenzo Crociani 19 Nov '18

19 Nov '18

Hi, we upgraded ovirt from version 4.1 to 4.2.6. Rebooted all vms. We missed two vms that were at Cluster Compatibility Version 3.6. There was a gluster/network IO problem and vms got paused. We were able to recover all the other vms from the paused state but we have two vms that won't run because: "Cannot run VM. The Custom Compatibility Version of VM VM_NAME (3.6) is not supported in Data Center compatibility version 4.1." Can we force the CCV of the paused vm to 4.1? Regards, -- Marco Crociani

ovirt-guest-agent running on Debian vm, but data doesn't show in web-gui

Software Version:4.2.5.2-1.el7 Installed agent (1.0.14, from source) following this: https://www.ovirt.org/documentation/how-to/guest-agent/install-the-guest-ag… Some vm's run 1.0.13, but I have the same problem there.

iSCSI constantly reading from storage (about 8 Mbps) after connecting hosts to storage
by silvio.delval＠pandasecurity.com 17 Oct '18

17 Oct '18

Hello, I recently deployed oVirt in some hosts to evaluate it as one of my main virtualization tool. I like it a lot, but I don't know if this behaviour is normal: I just configured my iSCSI network against a IBM V7000, and from that point on, the host with the role "SPM" continuosly is reading from storage at about 7 or 8 Mbps. I don't know what it i doing, due to no storage domains are still created. How can I know what it is doing ? Regards, Silvio

custom emulated machine in L2 ESXi
by Gianluca Cecchi 16 Oct '18

16 Oct '18

Hello, I had similar problem in the past with ESXi 6.0 U2 host where I defined a VM and used it as oVirt node for nested virtualization. If I run on this "virtual" node an L2 VM all went well until custom emulated machine value was at "pc-i440fx-rhel7.2.0". At some point the default became 7.3 and the L2 VM was not able to boot any more: it remained in blank screen at boot. The same up to now in 4.2.6.1 where this default seems to be 7.5 I'm having same problem in a mini lab on a nuc6 where I have ESXi 6.7 installed and try to setup an hosted engine environment. This problem prevents me to configure the hosted engine because the L2 VM that should be the hosted engine freezes (?) during its first startup and I see indeed that the qemu-kvm process is started with option "-machine pc-i440fx-rhel7.5.0" Being stated that I'm in an unsupported configuration, I would like to understand if I can correct in some point and proceed. So some questions: 1) How can I understand what is the difference between running qemu-kvm with "-machine pc-i440fx-rhel7.2.0" ad "-machine pc-i440fx-rhel7.5.0" so that I can then dig with ESXi parameters eventually to tune the settings of its VM that becomes my oVirt hypervisor? 2) Do I have any chance to configure my oVirt node so that when it runs the hosted-engine deploy it runs the engine VM with 7.2 parameter? Any conf file on host where I can somehow force 7.2 compatibility or set it as default? 3) during gluster base hosted-engine deployment at first "local" startup how can I connect to the console of the hosted engine VM and see where it is blocked? Thanks in advance, Gianluca

4.2 User Portal
by Стаценко Константин Юрьевич 16 Oct '18

Hello! Users cannot edit and expand VM’s disks from the User Portal after 4.2 upgrade anymore. VM UI screenshot attached. Users can press Edit icon, but only “Editing” appears and nothing more. Same thing happens under admin’s accounts on User Portal. From Admin Portal everything is fine. How can we fix this issue, so users can edit they VM from the User Portal as it was in 4.1 ? Thanks.

VLAN tagging with external provider networks
by anurag.porripireddi＠bigswitch.com 12 Oct '18

Hi, I see that checking the "External provider" box whilst creating networks clears and grays out VLAN tagging. Is VLAN tagging for external provider networks not supported? Thanks, Anurag

Info on HCI single host
by Gianluca Cecchi 11 Oct '18

11 Oct '18

Hello, following this reference guide: https://www.ovirt.org/documentation/gluster-hyperconverged/chap-Single_node… after having run with success the gdeploy based gluster setup, there is Setting up Hosted Engine Use the Ansible based installation flow of Hosted Engine to set up oVirt within a virtual machine. The storage details should be provided as type: glusterfs and connection path as: <hostname>:/engine (Replace hostname with address of host on which installation is carried out) What does exactly mean "Use the Ansible based instalation" ? Does it mean using cockpit web ui? In this casae I suppose I have to choose: Hosted Engine Deploy oVirt hosted engine on storage that has already been provisioned Correct? Thanks, Gianluca

IPoIB broken with ovirt 4.2.6
by Giulio Casella 10 Oct '18

10 Oct '18

Hi, latest ovirt node stable (4.2.6 today) introduced a bug in kernel: IP over infiniband is not workingh anymore after an upgrade, due to kernel 3.10.0-862.11.6.el7.x86_64. You can find some detail here: https://bugs.centos.org/view.php?id=15193 dmesg is full of "failed to modify QP to RTR: -22", and the networking stack (in my case used to connect to storage) is broken. The interface can obtain an address via DHCP, but also a simple ICMP ping fails. Does someone have news about a fix for this issue? TIA, Giulio

New oVirt deployment suggestions
by Stefano Danzi 08 Oct '18

08 Oct '18

Hello! I'm almost ready to start with a new oVirt deplyment. I will use CentOS 7, self hosting engine and glusert storage. I have 3 phisical host. Each host has four NIC. My first idea is: - configure bond betwheen NICs - configure a VLAN interface for management network (and local lan) - configure a VLAN interface for gluster network - configure gluster for the hosted engine - start "hosted-engine --deploy" process is this enough? do I need a phisical dedicated NIC for management network? Bye

[OT] transferring kvm raw mage from filesystem to lvm based
by Gianluca Cecchi 02 Oct '18

02 Oct '18

Hello, I have a windows 7 VM that is composed by a raw disk on filesystem on Fedora 28. I would like to transfer this VM to another environment, always based on same version of Fedora 28, but where the storage is configured in virt-manager as lvm based, so similar to what happens in oVirt block based storage domains. I'm trying to figure how to transfer the image. I presume I can create a new LV and then leave some bytes for the LVM header into the created LV and then make a sort of dd with offset? Anyone has any hint? Thanks in advance, Gianluca
