[ovirt-users] Re: Diskless oVirt Nodes
It would be nice. Initially when I was setting my lab I wanted to boot from USB and be able to host Vms properly but due to speed limitations - it failed to work normally. Maybe in-memory mode could be nice where booting from USB is possible.

It used an ISO image loaded to a RAM disk and a readwrite filesystem on disk for stuff we wanted/needed to change/keep. I wasn't part of the design process for node, but I do not think that "running diskless" was considered as a feature we want - neither in legacy nor in NG. > this is a key point that makes some people choose something like ESXi(that > loads into RAM and therefor is not dependent of the boot disk for running) > over oVirt node NG. Perhaps. > Do you think it is possible to get this back in oVirt node NG? I think it's possible, but obviously requires work. I have no idea how much work. As I suggested before, you can file an RFE. If enough people want this, and/or if someone provides patches, it's more likely to be added eventually.

[ovirt-users] Re: hosted engine migration
I think that you can try to set one of the HE hosts into maintenance and then
use UI to 'reinstall'. Don't forget to mark the host as a HE host also (some
dropdown in the UI wizard).

Sorry, I wasn't aware that this was disabled since 4.3.5, about a year ago:
https://gerrit.ovirt.org/#/q/Ia06b9bc6e65a7937e6d6462c001b59572369fe66,n,z
So you'll have to first fix migration on engine level.
