Re: [ovirt-users] Importing existing KVM hosts to Ovirt

I don't have that user at all.
The old hosts have only libvirtd installed and running kvm hosts

Also instruction is for XEN, we don't run XEN VMs

So it

Re: [ovirt-users] storage redundancy in Ovirt

[Konstantin Raskoshnyi]

Hi Nir,
BMC - board management controller, in my case I have ilo.
Yes I set up power management for all hosts - ovirt sees ilo status as ok.
I use remote pdu to shutdown the port, after that happens the picture I
attached.
After I switch power port on, ovirt is able to read ilo status, sees that
Linux is down and immediately switches the spm server.

But actually, it didn't work well. After main SPM host went down I see this

So that means only if BMC is up it's possible to automatically switch  SPM

Makes sense.
I was trying to set it up, but doesn't work with our staging hardware.
We have old ilo100, I'll try again.

"Corner cases"?
I tried to simulate crash of SPM server and ovirt kept trying to
reistablished connection to the failed node.

Re: [ovirt-users] storage redundancy in Ovirt

Hi Fernando,
I see each host has direct connection nfs mount, but yes, if main host to
which I connected nfs storage going down the storage becomes unavailable
and all vms are down

Re: [ovirt-users] storage redundancy in Ovirt

[Konstantin Raskoshnyi]

In ovirt you have to attach storage through specific host.
If host goes down storage is not available.

[ovirt-users] storage redundancy in Ovirt

[Konstantin Raskoshnyi]

Hi guys,
I have one nfs storage,
it's connected through host1.
host2 also has access to it, I can easily migrate vms between them.

The question is - if host1 is down - all infrastructure is down, since all
traffic goes through host1,
is there any way in oVirt to use redundant storage?

Only glusterfs?

Thanks

[ovirt-users] Importing existing KVM hosts to Ovirt

[Konstantin Raskoshnyi]

Hi guys, I just installed oVirt 4.1 - works great!

But the questing is, we have around 50 existing  kvm hosts, is it really
possible during adding them to oVirt add all VMs from them to oVirt?

Second options I see - import disks to oVirts and re-create machines

Thanks for the help.

[ovirt-users] Adding existing kvm hosts

[Konstantin Raskoshnyi]

Hi guys, We're never had mgmt for our kvm machines

I installed oVirt 4.1 on CentOS73 and trying to add existing kvm hosts but
oVirt fails with this error

2017-04-12 05:08:46,430Z ERROR [org.ovirt.engine.core.uutils.ssh.SSHDialog]
(org.ovirt.thread.pool-7-thread-21) [4a1d5f35] Exception:
java.io.IOException: Command returned failure code 1 during SSH session
'root@tank3'

I don't experience any problems connecting to virtank3 under root.
