[ovirt-users] Nested oVirt : Unofficial network recommendations wanted

Hello, I'm trying to setup a nested oVirt for the first time, and according to what I read around and experience, some special network settings have to be chosen. For this first try, the bare-metal host is a Debian, running KVM, and the virtual NICs are setup as macvtap in VEPA mode. I'm not up to date with macvtap, but I think I understood that one of its limit was that no packet could be exchanged between the host and the guests. So far, this is leading me to access my own local VMs from another host. Too bad. I'm also witnessing frequent loss of packets. So far, I'm also seeing that guests can not ping each others, so I'm not going further before having solved these basic issues. I'm remembering the good old times of lots of bridges where my VMs could be reached by anyone (this was desired), but virt manager is not offering me this choice. I also would like to avoid NAT for other reasons. To you all (4) people who are playing with nested oVirt : - which is your preferred bare metal OS? - which is your preferred guest (first virt level) OS? - which network setups and modes are working best? Thank you. -- Nicolas ECARNOT
