Same here. To eliminate some variables, I turned off my dnsmasq
service, disabled it and rebooted. The problem is still there: for a
few moments the guests are network-reachable, then they aren't. They
may come back, they may not. Or one does and the other doesn't. It's
completely unpredictable. If I could even figure out which component is
causing the problem I could BZ it, but nothing stands out.
I'll keep looking but I'm seriously considering a complete system
reinstall, something I haven't done in about 5 years, in case some
cruft from earlier iterations of Fedora is somehow lurking in the
shadows.
Well, I can't say that I've ever seen "intermittent" problems like that
caused by SW. But
since the host and guest are on the same HW it seems to be the only thing that makes
sense.
The only thing that comes to mind is that communication on a LAN with IPv4 takes place
based on the MAC address and ARP request/response. If somehow guest obtained the same
MAC
address for their interfaces one may see odd behavior.
