Folks, I'm noticing that OpenBSD guests under vbox 4.1.2/FreeBSD-8-stable don't seem to be able to form proper CARP groups on internal networks. The emulated CARP interfaces report as good within the guest OpenBSD machines, and CARP failover reports operation as usual. BUT, other guests on the same internal net can't hit the CARP address. Reverting to virtualbox-ose-legacy fixes this. CARPs, and even carpnode load sharing, then work fine. Can anyone offer some insight? Perhaps there's an option setting I've missed? The machine in question was csup'd to 8-stable and then fully rebuilt (buildworld) on Wednesday 12 October. Both versions of vbox + vbox-kmod were then successively built from the ports tree and tested against the same set of guest images. FWIW, pinging a carp in the 4.1 situation yields a valid arp cache entry on the sending end, but a tcpdump on the receiving interface comes up empty. regards, Ross -- Ross Alexander, (780) 675-6823 desk / (780) 689-0749 cell, rwa@athabascau.ca "Always do right.
