Re: [libvirt] [PATCH v2] bhyve: add e1000 nic support

Recently e1000 NIC support was added to bhyve; implement that in the bhyve driver: - Add capability check by analyzing output of the 'bhyve -s 0,e1000' command - Modify bhyveBuildNetArgStr() to support e1000 and also pass virConnectPtr so it could call bhyveDriverGetCaps() to check if this NIC is supported - Modify command parsing code to add support for e1000 and adjust tests - Add net-e1000 test ---
