[ovirt-users] gfapi, 3.5.1

Hi, Will the vdsm patches to properly enable libgfapi storage for VMs (and matching refactored code in the hosted-engine setup scripts) for VMs make it into 3.5.1? It's not in the snapshots yet it seems. I notice it's in master/3.6 snapshot but something stops the HA stuff in self-hosted

Re: [ovirt-users] Change gluster primary

Hi John, There isn't really a primary in gluster. If you're using a glusterfs storage domain, you could turn off nix and the VMs would continue to run (although you'd have to disable quorum if you currently have it enabled on the volume, and you'd have to repoint the domain at some later

Messed up the quote. removed it for clarity: One thing that would render this whole issue moot is being able to use local fast storage on the hypervisor hosts, ie SSD or 3D-Xpoint drives in LVM-Cache to accelerate IOPS on shared storage. The underlying stuff is already there, and it works.

There are many things that tie a VM to a host, like USB device passthrough, but that's not reason to remove all such support from oVirt, is it? In my case, I'd like to mix iSCSI and local storage, because I have a couple of systems that need higher disk I/O that I'd like to put on my shared

Hi, If you have set up VM disks as Thin Provisioned, the VM has to pause when the disk image needs to expand. You won't see this on VMs with preallocated storage. It's not the SAN that's running out of space, it's the VM image needing to be expanded incrementally each time. Cheers Alex
