It has CPU Intel Core i7 4600U vPro + VT-d. Host: Debian 8 x64 + VBox 4.3.18 +PUEL extpack (kernel 3.16) Guest: Debian 8 x64 (no additions) lspci on host shows: 00:19.0 Ethernet controller: Intel Corporation Ethernet Connection I218-LM (rev 04) I did: VBoxManage modifyvm ""Debian 8 netinst"" --pciattach 00:19.0@01:05.0 The device was actually removed from host and moved into VM, so far so good. But the guest doesn't receive any packets (not even DHCP client), and the link is shown as not detected via ""ethtool"" from the guest, as if the link is down. Why i get no network connectivity in VM ? -Technologov, 21.Oct.2014." defect closed VMM VirtualBox 4.3.18 obsolete other Linux
