[ovirt-users] Engine HA-Issues

[Sven Achtelik]

Hi All,

after running solid for several month my ovirt-engine started rebooting on 
several hosts. I've looked into the hostend-engine -vm-status and it sees that 
the engine is up on one host but not reachable. At the same time I can access 
the gui and everything is working fine. After some time the engine is shutting 
down and all hosts are trying to start the engine until one is the winner, at 
least it looks like this. Any clues where to look at and find the issue with 
the liveliness check ?

Re: [ovirt-users] Installation oVirt node and engine on the same machine

[Vinícius Ferrão]

WC, here is one guide. The procedure is what Alexander said: self-hosted engine.

Re: [ovirt-users] oVIRT 4.1.3 / iSCSI / VM Multiple Disks / Snapshot deletion issue.

[Devin Acosta]

You can get my logs from:

https://files.linuxstack.cloud/s/NjoyMF11I38rJpH

They were a little to big to attach to this e-mail. Would like to know if
this is the similar bug that Richard indicated is a possibility.

Why not go with hosted engine at that point. hosted engine is basically a VM 
running the engine in the system. There should be lots of guides available on 
how to get it up and running.

Re: [ovirt-users] Windows USB Redirection

[Abi Askushi]

Hi Michal,

Thank you for your tip.
Do you have any example how this attribute can be extended to avoid
changing the default?

Thanx
Abi
