From: Fabian Freyer <fabian.freyer(a)physik.tu-berlin.de&gt; At the moment this is just one check, but separating this out into a separate function makes checks more modular, allowing for more readable code once more checks are added. This also makes checks more easily testable.

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 - Add net-e1000 test --- src/bhyve/bhyve_capabilities.c | 27 ++++++++++++++++++ src/bhyve/bhyve_capabilities.h | 1 + src/bhyve/bhyve_command.c | 32 +++++++++++++++++++--- .../bhyvexml2argvdata/bhyvexml2argv-net-e1000.args | 9 ++++++ .../bhyvexml2argv-net-e1000.ldargs | 3 ++ .../bhyvexml2argvdata/bhyvexml2argv-net-e1000.xml | 22 +++++++++++++++ tests/bhyvexml2argvtest.c | 7 ++++- 7 files changed, 96 insertions(+), 5 deletions(-) create mode 100644 tests/bhyvexml2argvdata/bhyvexml2argv-net-e1000.args create mode 100644 tests/bhyvexml2argvdata/bhyvexml2argv-net-e1000.ldargs create mode 100644 tests/bhyvexml2argvdata/bhyvexml2argv-net-e1000.xml diff --git a/src/bhyve/bhyve_capabilities.c b/src/bhyve/bhyve_capabilities.c index be68e51..0ff34a3 100644 --- a/src/bhyve/bhyve_capabilities.c +++ b/src/bhyve/bhyve_capabilities.c @@ -192,6 +192,30 @@ bhyveProbeCapsRTC_UTC(unsigned int *caps, char *binary) return ret;
