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.
On what device you attached it? Bridge? the physical nic?
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.
