Guest OS network doesn't work on 10.11 El Capitan

[tquang]

Dear friends,

I'm clean install new MacOSX 10.11 El Capitan, then install VirtualBox and guest OS (CentOS 6 64bit). I searched and not found any information helpful. So, could you please let me know why: from my mistak or bug of VirtualBox for now?

VirtualBox installed in Rootless mode (disable SIP)!

Thanks!

You would have to expand on "doesn't work", and also tell us what networking mode you are using (e.g. NAT or bridged). I would also check if IPv6 is involved, and if so, does everyone support it.

Dear mpack, thank you for your reply, I mean "doesn't work" just guest OS can not take IP from DHCP of VirtualBox. On my guest OS, I config with 2 network:
_1 for NAT
_1 for HOST

And no bridge, no enable ipv6 just ipv4

I must run command by manual: dhclient (add to rc.local). I think something wrong because I never do this before

I will move you to "Linux Guests" and then leave you in the capable hands of those who are more familiar with Linux than I.

Before I install MacOS 10.11, the guest os linux run nomal!
