ovirt-guest-agent on windows : what Python env. needed?

by Nicolas Ecarnot

Hello, I read the following page : http://www.ovirt.org/OVirt_Guest_Agent_For_Windows and applied it on a server, and it ran very well. I obtained the two executables, copied them into "program files" according to the doc, along with the .ini as stated here : https://www.mail-archive.com/users@ovirt.org/msg18561.html - the "-install", the start, and the enabling went fine - rebooting the server runs OK too, and the agent is seen by oVirt What I don't understand is the following sentence of … [View More]

hosted-engine setup/migration features for 3.6

by Yedidyah Bar David

Hi all, We already have quite a lot of open ovirt-hosted-engine-setup bugs for 3.6 [1]. Yesterday I tried helping someone on irc who planned to migrate to hosted-engine manually, and without knowing (so it seems) that such a feature exists. He had an engine set up on a physical host, prepared a VM for it, and asked about migrating the engine to the VM. In principle this works, but the final result will be a hosted-engine, where the engine manages a VM the runs itself, without knowing it, and … [View More]
