Cannot ping from guest to host and viceversa.

Guest is CentOS 6.7, default minimal installation + updates. Host is Windows 10 running VirtualBox 5.

Both machines configured with static ip addresses and same subnet. Windows 10 firewall disabled. CentOS network is bridged.

ifconfig from CentOS:

arp -a from Windows 10 ("statico" means static, "dinamico" means dynamic):

I was hit by the same error when I upgraded Virtualbox from 5.0.2 to 5.0.4.

Inspired by this Reddit Post I downgraded virtualbox back to 5.0.2 and the problem disappeared. So it seems to be a bug introduced with 5.0.4.

  • I upgraded to 5.0.8. today and everything works as expected, so they seem to have fixed the issue. – Zord Nov 4 '15 at 9:32
  • Me too, problem fixed I guess – user34295 Nov 4 '15 at 9:32
