Bridge Issue
by Constantinos L 11 Oct '19

11 Oct '19

Hello all, I am trying to setup a bridge. I have 3 virtual machines. The 1st acting as router, the second acting as bridge and the 3rd is the client, like the following diagram ROUTER BRIDGE CLIENT internet(ovirtmng network) ----- [eth0 router --eth1 ] -------[eth0 --[br0]-- eth1] -------[--eth Windows 10] The problem is that windows 10 is not able to connect the internet although is able to allocate ip. I use ovirt external network to connect the VMs to each other. It seems that Windows 10 sends ARP to BRIDGE, the BRIDGE sends the ARP to ROUTER but the replies are not passing the br0 when it comes a reply from ROUTER to Windows 10. I use oVirt 4.3.6. Do you know what should be the issue ? Is there a chance that ovirt blocking the bridge?

Re: owner of vm paused/unpaused operation

You can always check the queue_if_no_path multipath.conf option and give it a try. But if your system that is queue-ing get's rebooted - that will be data loss -> use on your own risk. Don't forget that the higher in I/O chain you go - the higher the timeout is needed, so your VM should also use multipath with that option, in addition to the host. Still, we can't help you if you use that feature and you loose data.

iSCSI storage domain with no switch
by MIMMIK _ 10 Oct '19

10 Oct '19

Is it possibile to have a storage domain on an iSCSI LUN if the storage is connected to the cluster physical nodes with no switch and only direct connections? This is the scenario: - we have two physical nodes with 2 iSCSI ports each. - the storage has 2 controllers, 2 iSCSI ports on each controller - each server is directly connected with a port to a storage port on a controller and to another storage port on the other controller. Do you think is this possibile, maybe using any trick or workaround? Thanks. Regards

You can create an NFS on that host and export to itself that local storage...

owner of vm paused/unpaused operation
by Gianluca Cecchi 10 Oct '19

10 Oct '19

Hello, I'm doing some tests related to storage latency or problems manually created to debug and manage reactions of hosts and VMs. What is the subsystem/process/daemon responsible to pause a VM when problems arise on storage for the host where the VM is running? How is determined the timeout to use to put the VM in pause mode? Sometimes I see after clearing the problems that the VM is automatically un-paused, sometimes no: how is this managed? Are there any counters so that if VM has been paused and and problems are not solved in a certain timeframe the unpause can be done only manually by the sysadmin? Thanks in advance, Gianluca

Hyperconverged setup questions
by Vrgotic, Marko 10 Oct '19

10 Oct '19

Dear oVirt, Is it possible to add oVirt 3Hosts/Gluster hyperconverged cluster to existing oVirt setup? I need this to achieve Local storage performance, but still have pool of Hypevisors available. Is it possible to have more than 3Hosts in Hyperconverged setup? I have currently 1Shared Cluster (NFS based storage, where also SHE is hosted) and 2Local Storage clusters. oVirt current version running is 4.3.4. Kindly awaiting your reply. — — — Met vriendelijke groet / Kind regards, Marko Vrgotic ActiveVideo

Re: Delete snapshots task hung

Maybe you can change the status of the VM in order the engine to know that it has to blockcommit the snapshots.

Upgrading from oVirt-Node 4.2.8 to latest
by Sven Achtelik 10 Oct '19

10 Oct '19

Hi All, is there a way to go from 4.2.8 on ovirt node to go directly to the latest version, without reinstalling the node from the iso file ? I wasn't able to find anything in documentation on how to get this done. Thanks, Sven
