multiple subnets on hosts for vm's
by eevans＠digitaldatatechs.com 12 Apr '20

12 Apr '20

This is not critical but some functionality I think should be in Ovirt and maybe I am going about it the wrong way. I have several subnets on my physical network. My engine host is separate from the clustered hosts that house the vm's. In order for the vm's on the other subnets (vlans) to get Internet access, I have to add the extra ip addrs on the ovirtmgmt network interface. I have read and tried every solution I could find trying to add teh subnets without using the extra ip addrs option but the machine either becomes isolated or will not start at all. Can someone tell me how to add the vlans so the engine host sees and utilizes them? The engine host can get to resources on the vlans because of the router config but will not let any subnet except ovirtmgmt outside the cluster. This is not critical but something I would like to get working for future deployments. Thank you for your help. Eric

Storage domain in maintenance
by Strahil Nikolov 11 Apr '20

11 Apr '20

Hello All, I have several storage domains in maintenance mode and I can't neither detach, nor activate. Can someone explain to me what is actually doing the engine whwn I try to activate - so I can debug it? The error from vdsm-client is that the storage domain does not exist, yet it is in the DB . I assume that there is somw storage issue, but in order to debug it - I need to know what is gooing on under the hood. Thanks in advance Best Regards, Strahil Nikolov

Windows 10 Pro 64 (1909) crashes when migrating
by Maton, Brett 11 Apr '20

11 Apr '20

I recently added a Windows 10 Pro 64 bit (release 1909) VM, and I'm seeing a lot of failures when oVirt tries to move the VM to another host (triggered by load balancing), These errors are showing up in the UI event log Migration failed (VM: <vm label>, Source: <host 1>, Destination: <host 2>). Followed by: VM <host> is down with error. Exit message: Lost connection with qemu process. Google returned some references to 'options kvm ignore_msrs=1' which I've added to /etc/modprobe/d/kvm.conf and restarted the hosts but that doesn't appear to have made a difference. Is this a known issue with Windows 10 guests?

Firewall GARP not reachable to VM
by k.betsis＠gmail.com 10 Apr '20

10 Apr '20

Hi all Does anyone know how i can allow my Firewall VM cluster act as the default gateway to VMs within the same network? I've configured the GARP functionality on the OPNSENSE firewalls (PFSENSE fork). VMs within the same network can ping the firewall IP addresses successfully but not the GARP IP. The ovirt network has been configured with the MAC Address Anti-spoofing to false. One firewall has been configured with virtio network drivers and the with e1000 both exhibiting the same behavior. Currently all VMs have been configured with a default gateway the primary firewall. Network workarounds using BGP and attributes can work, but are way to complicate to streamline for all VMs when a simple VRRP can do the job. Any ideas what i am missing?

Ovirt and Dell Compellent in ISCSI
by dalmasso＠cines.fr 10 Apr '20

10 Apr '20

hi all, we use ovirt 4.3 on dell server r640 runing centos 7.7 and a storage bay Dell Compellent SCv3020 in ISCSI. We use two 10gb interfaces for iSCSI connection on each dell server. If we configure ISCSI connection directly from web IU, we can’t specify the two physical ethernet interface , and there are missing path . (only 4 path on 8) So, on the shell of hypervisor we use this commands for configure the connections : iscsiadm -m iface -I em1 --op=new # 1st ethernet interface iscsiadm -m iface -I p3p1 --op=new # 2d ethernet interface iscsiadm -m discovery -t sendtargets -p xx.xx.xx.xx iscsiadm -m node -o show iscsiadm -m node --login after this, on the web IU we can connect our LUN with all path. Also, I don’t understand how to configure multipath in the web UI . By defaut the configuration is in failover : multipath -ll : 36000d3100457e4000000000000000005 dm-3 COMPELNT,Compellent Vol size=500G features='1 queue_if_no_path' hwhandler='0' wp=rw `-+- policy='service-time 0' prio=1 status=active |- 23:0:0:1 sdb 8:16 active ready running |- 24:0:0:1 sdd 8:48 active ready running |- 25:0:0:1 sdc 8:32 active ready running |- 26:0:0:1 sde 8:64 active ready running |- 31:0:0:1 sdf 8:80 active ready running |- 32:0:0:1 sdg 8:96 active ready running |- 33:0:0:1 sdh 8:112 active ready running |- 34:0:0:1 sdi 8:128 active ready running I think round robind or another configuration will be more performent. So can we made this configuration , select physical interface and configure multipath in web UI ? for easyly maintenance and adding other server ? Thank you. Sylvain.

oVirt 4.4.0 Beta release refresh is now available for testing The oVirt Project is excited to announce the availability of the beta release of oVirt 4.4.0 refresh for testing, as of April 9th, 2020 This release unleashes an altogether more powerful and flexible open source virtualization solution that encompasses hundreds of individual changes and a wide range of enhancements across the engine, storage, network, user interface, and analytics on top of oVirt 4.3. Important notes before you try it Please note this is a Beta release. The oVirt Project makes no guarantees as to its suitability or usefulness. This pre-release must not to be used in production. In particular, please note that upgrades from 4.3 and future upgrades from this beta to the final 4.4 release from this version are not supported. Some of the features included in oVirt 4.4.0 Beta require content that will be available in CentOS Linux 8.2 but can’t be tested on RHEL 8.2 beta yet due to some incompatibility in openvswitch package shipped in CentOS Virt SIG which requires to rebuild openvswitch on top of CentOS 8.2. Known Issues - ovirt-imageio development is still in progress. In this beta you can’t upload images to data domains using the engine web application. You can still copy iso images into the deprecated ISO domain for installing VMs or upload and download to/from data domains is fully functional via the REST API and SDK. For uploading and downloading via the SDK, please see: - https://github.com/oVirt/ovirt-engine-sdk/blob/master/sdk/examples/upload_d… - https://github.com/oVirt/ovirt-engine-sdk/blob/master/sdk/examples/download… Both scripts are standalone command line tool, try --help for more info. Installation instructions For the engine: either use appliance or: - Install CentOS Linux 8 minimal from http://centos.mirror.garr.it/centos/8.1.1911/isos/x86_64/CentOS-8.1.1911-x8… - dnf install https://resources.ovirt.org/pub/yum-repo/ovirt-release44-pre.rpm - dnf update (reboot if needed) - dnf module enable -y javapackages-tools pki-deps 389-ds - dnf install ovirt-engine - engine-setup For the nodes: Either use oVirt Node ISO or: - Install CentOS Linux 8 from http://centos.mirror.garr.it/centos/8.1.1911/isos/x86_64/CentOS-8.1.1911-x8… ; select minimal installation - dnf install https://resources.ovirt.org/pub/yum-repo/ovirt-release44-pre.rpm - dnf update (reboot if needed) - Attach the host to engine and let it be deployed.

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
