Your multipath errors may be related to ovirt, but only because vdsm requires and starts multipathd, and install new multipath.conf. I suggest to try to get help about it in device-mapper channels (e.g. #lvm on freenode). If you cannot resolve this, please open a bug.

So should I detach the domain, update the tarball then reattach it. The problem lies with machines that have already been imported once before.

Hello, I have IBM Power 6 Server (p520), having 24 GB of RAM and 8 CPUs. As the server is having adequate resources, I would like to implement "Virtualization Environment". So, let me know if "oVirt" is having compatibility on Fedora 20. Here, please note that *IBM Power Server* make is *P520*, *8203-E4A*. Also, it's request you to provide some technical documentation to install & configure oVirt on Fedora 20 ppc64 only. Regards, *Nishith N.Vyas*

Re: [ovirt-users] change network MTU settings without taking all the VMs down?
by Darrell Budic 05 Feb '15

05 Feb '15

I wound up manually changing the network configs on my hosts during other updates, one at a time. Then I migrated off the lower MTU host and repeated. Seemed to be minor extra bit of pause after migration completed, then things were fine (and I manually updated MTU settings on the VMs at that time, without rebooting/shutdowns). I did have to reboot one VM that went to 100% cpu and didn’t recover, but it has done that before and I think it’s a different problem with that one in particular, not the process. Then I repeated on the other host. Both though the networks in question were not synchronized, but came up fine away. Once that was all done, I updated the MTU values via the database, and now ovirt thinks everything is happy. So the manaul process Loir describes for 3.4 works, and works for 3.5 if you manage it properly. I’m still set with my vdmds forced to ifcfg persistence due to troubles with bonded interfaces in 3.5, so this was easy for me. -Darrell > On Jan 28, 2015, at 11:37 AM, Donny Davis <donny(a)cloudspin.me> wrote: > > So adding a new network was the way you went??On Jan 28, 2015 9:22 AM, Darrell Budic <budic(a)onholyground.com> wrote: >> >> 3.5.1.

I see the GUI won’t let me do that while the network is in use. Any way around this, clean or otherwise? Restarting VMs to update them is ok, just trying to avoid having to take everything down at the same time. >>>>> >>>>> -Darrell >>>>> _______________________________________________ >>>>> Users mailing list >>>>> Users(a)ovirt.org >>>>> http://lists.ovirt.org/mailman/listinfo/users >>>>> >> >> _______________________________________________ >> Users mailing list >> Users(a)ovirt.org >> http://lists.ovirt.org/mailman/listinfo/users
